You may think that the best apps have a price, but more of them are actually free. If you pay for the app, the cost is still affordable anyway. Who says the best things for life are not for free? Here is a list of the best apps that you can find in the Android market:
1. The Weather Channel
The Weather Channel is one of the best Android apps that you can download from the Android market. The newly enhanced Weather Channel gives you a much better and richer weather experience. Due to customers’ feedback, many improvements were made such as a brand new user interface that includes user-friendly navigation between main weather screens and easier access to maps like animated radar and personalized weather maps. These weather maps are also capable of giving specific weather forecasts, conditions, alerts, notifications and the current temperature.
2. Facebook for Android
Sometimes, accessing Facebook through your browser is too tedious, especially when you know that there is an easier way of connecting with your friends. Facebook is always synonymous to staying in touch with the world. All people have an account; maybe your grandparents do, too. The success of Facebook is so overwhelmingly successful that Android developers created an application for you to access your account anytime and anywhere. Essentially, Facebook is a social network that allows you to do anything like chat with your friends, check news feeds, review events, share links, check messages, upload photos, watch videos and play games. Downloading the free Facebook for Android will allow you to keep in touch with your old friends and meet new people.

One of the greatest social networking sites that have invaded the Android market, Twitter remains to be a top pick among busy people who do not have the time for Facebook. Most celebrities, political figures and other VIPs are quite active in using Twitter. This Android app allows you to access important updates on what’s happening around the globe, like business, sports, music, politics, entertainment and travel. You can view many interesting topics on what people are talking about. You can also send private messages to your friends, share photos, videos, view maps and a lot more.
4. Angry Birds
When you feel the need for relaxation, fun and pleasure all you have to do is just to play Angry Birds from your Android device. It is one of the best games in the Android market. This game is for everyone to enjoy. Based on the laws of physics, you would not think that this game will be forgotten just yet. Aside from all the fun-filled launching of the revengeful birds, you get to play this game for free. The best thing is that developers keep on releasing new versions every now and then.
5. Kindle
Probably the best Android app that can widen your knowledge and improve your reading skills is the Kindle. With the Kindle app, you will get the chance to access over 900,000 books in the Kindle library, such as newspapers, magazines and dictionaries. You can also read articles from the Wall Street Journal, as well the best sellers from the New York Times. You will also enjoy many benefits like customizing the page color and font size of your reading material. You can also use links from Google and Wikipedia for more information.
If you are wondering when you can be liberated from the frustration of not recognizing the numbers on your cell phone, kept in suspense on who keeps calling your spouse in the thick of night, or simply trying to trace the type of company your teenage child is keeping, here is a foolproof way to accurately and quickly trace phone numbers using the reverse cell phone lookup.
Compared to your endless sleepless nights of futile internet searches, the reverse cell phone lookup gives you specific, accurate, updated and collated information any time at your own convenience. Here are the simple steps in using the service. find a reliable service, ensure that you get sufficient word of mouth testimonials. Key the phone number into the search box. Select your choice of package, namely single or unlimited search option. Once completed, you will be presented with the full report of name, current and past addresses, location map, immediately family member details, and more. Some services will also provide personal background checks as well as criminal records.
For a small fee of less than a good meal even for the unlimited access package of the reverse cell phone lookup, you are liberated from the endless sleepless nights of futile online searches. A wise way to make the best value out out of your membership fee is to opt for the unlimited option especially when you have more than two to three numbers to search. This is because the total price of about three single searches is equivalent to the unlimited access package allowing you multiple searches for an entire year, which effectively means you enjoy free searches after the first three searches. So consider your potions carefully before you choose your package.
Android, also know as Droid, is an operating system for last generation mobile phones. The OS has been developed by Google and is currently the most spread operating system for smartphones in the world, used by more than 33% of the market. Android also runs on tablets developed by Google Inc. as well.
The purchase of Android by Google happened six years ago, in 2005, and the first time it was distributed was in November 2007. The unveiling was announced with the founding of the Open Handset Alliance, which is a consortium of 80 IT companies working for mobile phones improvements. Most of the code for Android was released by Google under the Apache License, which makes Android licensed as free software.
The OS is based on the Linux kernel and is written with middleware, libraries and APIs in C language, and includes Java-compatible libraries as well. Like the other very popular OS on the market, Apple’s iOS, Android has a large database of third-party applications developed by independent programmers or companies, most of them written in Java. More than 250.000 applications are currently available in the Android Market ran by Google. The applications can also be downloaded from other sites, but it is recommended to use the versions from the official market of the OS.
Android is right now the most popular and best-selling smartphone platform in the world, according to Canalys and comScore. Google’s OS was the best sold in the fourth quarter of 2010.
Since its original release, several updates were made for Android. Each version of Android has a code number and a nickname, and the most recent versions are the following: 2.0 Eclair, 2.1 Eclair, 2.2 Froyo, 2.3 Gingerbread, 3.0 Honeycomb, 3.1 Honeycomb and 3.2 Honeycomb. The 4.0 Ice Cream Sandwich version is set to be released in Q4 of 2011, being currently in the development and testing process.
Android is mainly powered up by hardware from the ARM architecture. The Android-x86 project offers support for x86 and Google TV uses a special version of Android, working on x86 as well. The first smartphone to use Android was HTC Dream, released in October 2008. Google collaborated with HTC for its first Android device, Google Nexus One, while the 2010 version was made in collaboration with Samsung: Google Nexus S.
Though it works on the Linux kernel, Android had some security issues over the time. In August 2010, a SMS Trojan infected a large number of devices, while in March 2011 Google found 58 malicious applications in the Android Market, which were downloaded to around 260.000 devices. Most of the applications were hiding Trojans and infected many devices. The latest study made in August 2011 stated that around half a million Android users were infected by malware in the first half of 2011.
Nevertheless, Android still remains one of the most popular operating systems in the world, and the only competitor, Apple’s iOS, is still placed quite at a distance in the ranks.
Chinese electronics manufacturer Xiaomi, known more for its affordable smartphones, is also a key player in the smart wearables segment. Riding on the …
Hybrid mobile applications are like any other applications you will see on your mobile. They get easily installed on your mobile device. You can look for these apps in the App stores. By using these apps, you can engage your friends via social media, play games, track your health, take photos and much more.
Hybrid mobile applications are developed using a combination of web technologies like CSS, HTML, and JS as same as websites on the internet. The major difference is that hybrid applications are hosted inside a native app which further uses a mobile platform’s WebView. Here, WebView is a chromeless browser window which is typically configured to run fullscreen.
In fact, hybrid mobile apps enable you to access various device capabilities viz. camera, accelerometer, contacts, and much more. However, inside mobile browsers don’t allow you to access these capabilities from it. Furthermore, hybrid mobile applications include native UI elements in those situations where it is necessarily required, as proved by Basecamp’s approach towards hybrid mobile application development.
It is not easy to answer the question how a mobile app is built. Similarly, hybrid mobile apps are no different. A well-written hybrid application should not behave or look any different than its native equivalent. However, users don’t care about it as they only want an app that works well. It is what actually matters to them. If you are trying to figure out whether a mobile application is hybrid or native, it would be like you are trying to differentiate rare grape varieties of wine.
Unless you are the one who really cares about this, it is not terribly important. What all matters are how your hybrid mobile application development is going to work in the long run as no one will care about how it was built. A hybrid mobile application is said to be good if it performs well for its users.
How are hybrid mobile applications built?
Like other websites are built, hybrid mobile apps follow the same manner. Both are built with a combination of technologies like CSS, HTML, and JS. Generally, a hybrid app targets a Web View which is hosted inside a native container rather than targeting a mobile browser. This allows its users to access various hardware capabilities of the mobile device.
Many hybrid mobile apps today leverage Apache Cordova, a simple platform that consists of a set of JavaScript APIs for accessing mobile device capabilities through plug-ins that are built with native code. These plug-ins include APIs in order to access the device capabilities like contacts, accelerometer, camera, and more. In fact, a huge number of plugins are built and maintained by mobile app developers community-at-large which is can be found in the Apache Cordova Plugins Registry. A group of plugins that have been properly tested, documented, and extended can be found at the Telerik Verified Plugins Marketplace.
If we talk about Apache Cordova, it was actually started as a project named PhoneGap. But nowadays, PhoneGap is considered as a distribution of Apache Cordova which includes additional tools. To know more about its history, you can check out Cordova, PhoneGap and what’s in a name?
Various application assets like CSS, HTML, JS are packaged via tooling through Apache Cordova for targeting platform SDKs. Once a hybrid app is built, it can be run just like any other app on the mobile device. Apache Cordova provides the tooling that is highly driven by a command line interface. However, mobile app developers can still leverage IDEs such as Visual Studio and effective solutions like the Telerik Platform to further increase productivity.
Since mobile app developers don’t want to be getting locked into proprietary platforms, so hybrid mobile apps give a way to mobile app developers for re-using their existing skills in web development. This mainly includes SDKs provided by platform vendors and the programming languages.
Hybrid mobile app development somehow looks appealing to a company’s bottom line such as Why hire a developer for each platform when you can hire one developer and target all of them through CSS, HTML, and JavaScript? But, the reality is actually a bit more complicated to accept.
Obviously, it’s true that mobile app developers become able to target multiple platforms with hybrid mobile app development. But when it comes to WebView or web runtime, each platform comes with a set of caveats. This is more true for Android and not consistent between OS versions.
Furthermore, there must be some unique capabilities of platforms to which a mobile app developer may wish to target. In such cases, a combination of platform-specific code and plugins must be utilized which will take advantages of those capabilities. Optionally, mobile app developers can take advantage of 3rd party web runtimes such as Crosswalk which can be further embedded into your hybrid applications.
When should you build a hybrid mobile application?
It is the foremost concern of every mobile app developer who wants to build a hybrid mobile app. The first thing you should do is to check your mobile application’s requirements. Before committing to a platform strategy must evaluate the technical merits as well as non-technical merits of hybrid mobile apps over the web and native mobile apps. You should first consider the following questions before developing a hybrid app:
– What are the technical abilities of your mobile development team?
– Which mobile app platforms do you wish to target?
– Are you looking to use the multiple capabilities of the mobile device?
– Do you want to distribute your apps through the app stores?
– Does the hybrid approach really live up to its promise in the coming years?
The above questions are needed to be answered properly before the development of mobile apps. You may further evaluate more questions in detail.
WHICH MOBILE APP PLATFORMS DO YOU WISH TO TARGET?
You may have a number of choices if you want to target more than one platform. This is because the web offers a highly interactive solution for this purpose. However, the mobile browser is your target. HYbrid apps lend itself to this due to its reliance upon the WebView.
On the other hand, Native apps find a unique space among this. In fact, you are essentially coupled to this platform if you rely upon platform-specific programming languages and vendor SDKs. For this case, Objective-C or Swift is used for iOS, Java is used for Android and C# is used for Windows phone.
DO YOU WANT TO DISTRIBUTE YOUR MOBILE APP VIA APP STORES?
If you want to distribute your app via an app store, you must build a native or hybrid app. You can not distribute sites through app stores. Hence, browser’s address bar is provided for this. Despite this limitation, whether you build a hybrid or native app, it is strongly recommended that you must have a website available for your mobile app. You need to create this because this will be the first place your app users might expect to go in case if they stuck with any problem.
ARE YOU LOOKING TO USE THE CAPABILITIES OF THE MOBILE DEVICE?
As compared to native and hybrid apps, websites have a limited set of abilities. These limitations are put up by a browser that effectively sandboxing it from mobile OS. A lot more device capabilities are exposed through HTML5 with the help recent developments with mobile browsers which include geolocation, camera, and others.
In spite of these advancements, support for advanced functionality is still limited. For an instance, streaming and media capture are still unsupported in various mobile browsers. Due to these limitations with mobile browsers, there are many mobile app developers who are compelled to evaluate native and hybrid apps as alternatives. These platforms enable mobile app developers to access device APIs. While in case of hybrid apps, plugins support this capability.
It is often said that native app development is best suited for apps where graphics performance is paramount. The best example is the mobile games which completely rely on complex visual interactions on the screen. No matter, how wonderful game app you have developed for your users and how flawlessly it operates from a functional perspective, you can expect this game app to have a very low app store rating if it is lacking energy. Due to these reasons, mobile app developers have long argued for using a hybrid approach to build their game applications.
However, there exist a number of solutions for hybrid mobile apps. This includes WebGL and HTML5 Canvas that are well-suited to build game applications. In fact, these technologies are most preferred and approachable for mobile app developers due to the presence of libraries like EaselJS, Paper.js, and others. This is not limited to game development only. Developers build more traditional, line-of-business apps by using frameworks like Kendo UI and Famo.us.
WHAT ARE THE TECHNICAL ABILITIES OF YOUR APP DEVELOPMENT TEAM?
The team’s technical abilities is another major factor when it is about to evaluate development options for mobile. To build native applications, you need to hire developers who are proficient and experienced with the programming languages of every platform that you wish to target and platform SDKs. But for building web and hybrid apps, you need to hire developers who use web technologies like CSS, HTML, and JS. You may also have a team that can target more than one platform with a single set of technologies. So, this is a worth considering when you have to evaluate your opinions.
DOES THE HYBRID APPROACH REALLY LIVE UP TO ITS PROMISE?
Lastly, it is important to know that hybrid is not the be-all and end-all approach for mobile app development. At the initiation of this article, I have thrown light upon the challenges of overcoming the inconsistencies between WebViews. While other challenges still remain. With hybrid app development, you can target the various features of a mobile platform in order to discover if they are inaccessible. This is because plugins used for them can be unreliable, out-dated or missing altogether. This takes you to the dilemma whether to remove an application feature or to write the plug-in by yourself.
You may find hybrid app development model restricted when you have to develop an app that requires numerous native features or an app where performance is critically required for the success of the app. With this situation, you may found yourself to forcefully choose native development technologies. However, these are considered as alternative approaches which let you build performant native apps without having core knowledge of tools like Android Studio and Xcode.
Furthermore, the JavaScript-based NativeScript framework allows developers to build Android and iOS apps that forego the WebView for interactive and enhanced performance. NativeScript provides 100% access to Android APIs and iOS, removing the reliance on plugins which prove limitations while developing hybrid apps. But it is also not the be-all-end-all approach for developing native applications. However, this approach to application development is powerful which become more powerful with a higher learning curve. With NativeScript, you would not be using HTML to build UI. So, NativeScript is seriously considered by app developers if they have to develop an application with non-trivial performance requirements
Although Android Marshmallow is out for some devices, many of the devices are still using Lollipop and are still receiving updates to the OS. Lollipop has been a spectacular operating system for Android with such amazing features, but there is no such thing as perfect, and Lollipop is no exception. There are many Android Lollipop issues and we’re going to list here some common Android Lollipop issues and their possible fix.
Crashing Apps:
The Lollipop update somehow introduced memory leaks that caused way too many problems all over. This Android Lollipop issue caused the apps to crash and have lag in the UI and even caused the UI to force stop without any kind of warning.
On high-end devices, this leak isn’t much noticeable, but for the older devices, this can cause a lot of problems.
Rebooting the device will only fix this temporarily and after a few days, the lag will return.
Clearing the Google play’s data will somehow solve the issue, but to permanently solve the issue you’ll have to wait for Google to release an official update.
Slow Charge:
If your device happens to charge a little slower than before, then you’re not actually alone in this matter. A lot of users are having this Android Lollipop issue and do note that charging from a PC will always be slow. Some potential solutions to this are.
• If you’re using a third-party charger, then that might be the reason of slow charging.
• The cable might be causing a problem, try charging it with another trusted cable.
• Clear your device’s cache partition.
Rapid battery drain:
A lot of users are complaining about this Android Lollipop issue that their mobile’s battery drains a lot faster than it used to or decreases really fast. This was a major issue in the first Lollipop update was later fixed with an update and should probably have a much better battery life than before. If you’re still facing the problem, try these.
• Update all your apps so they are compatible with the new OS and also clear their cache.
• Factory reset your device.
No audio on call:
Quite a few people have actually faced this Android Lollipop issue where they can’t seem to hear the caller and vice versa. This makes the user impossible to receive calls. The potential solutions to this are.
• Restarting your phone seems to solve the problem.
• Try using your headsets or a Bluetooth headset and then switch back to the audio of your device.
Camera is not working:
Not a lot of people have been facing this Android Lollipop issue but for those who have, this issue has frustrated them a lot. Some people have also been complaining about the camera buttons disappearing so even you cannot switch to the front camera. Some solutions to fix this issue are.
• Restart your mobile and then open the app.
• Force stop the camera app from settings and clear its cache and data and then restart your device
Google Play is not the one and only market for Android applications. Many people are incentivized to look for apps outside Google Play for a number of reasons. The main Android market is huge and popular, but on the other hand this makes new apps harder to discover. Alternative markets may include apps that were filtered out from Google Play, country-special apps, or simply be designed for special devices (such as Amazon Appstore).
Alternative application stores has concerns faced by both users and software owners. For users there is an increased risk of getting malware or apps with poor UX. For developers and software owners the problems may hide in terms and conditions of app deployment, as well as piracy issues. Not all alternatives to Google Play are equally useful, but some might be interesting for expanding the area of app distribution.
Google Play Store
We all know the giant Google Play, the primary target of developers’ efforts. Thus it’s not quite necessary to write much about it. Whatever stores you choose for your app, they are most likely to be complementary to this one, which holds more than million apps in its vaults.
Amazon Appstore
If we speak about the most popular alternative to Google Play, we speak about Amazon Appstore. This is the default store for Kindle Fire tablets, which run a forked version of Android and often top the lists of the most popular Android tablets. Therefore it may be useful for owners of tablet-optimized apps. For mobile users, there’s an interesting feature called ‘Test Drive’ that allows trying out an app by launching a virtual copy in the browser, and a popular free-app-of-the-day feature. For developers, there is a stricter quality control than on Google Play Store. Currently there are about 128,000 apps in Amazon Appstore, and it’s available in more than 200 countries worldwide.
Samsung Apps
Samsung is the biggest hardware manufacturer for Android, and it has its own application store, which can be accessed by an app called S Suggest, which is as well a trademark of Samsung. Apps must be submitted and must undergo the process of quality control and check of device compatibility, so here the risk of catching malware is minimal. The store has about 30,000 apps and works across 125 countries.
SlideME
Another alternative application store with over 21,000 Android apps, which has a relatively large community and a process of quality check. It’s globally available and supporting a number of payment options, the most popular being probably PayPal. It would be rather easy for your app to get noticed in this store. Other noteworthy peculiarities are SlideMe ad network and an opportunity to get more revenues than from the standard model, which works in three aforementioned stores (70% of revenues go to the software owner, 30% go to the store).
GetJar
GetJar dubs itself the world’s biggest open application store, and it’s not solely focused on Android. This independent vault contains 350,000 mobile applications for Android, BlackBerry, Windows Mobile, and minor platforms. Like in other stores, it’s easy for a user to discover and find apps through categories and subcategories. This is an immensely popular free app repository which is quite capable of bringing additional users for your software product.
You may always browse for detailed information about these and other stores (such as Opera Mobile Store or LG Smart World), and you may consult with your developer before planning the distribution of your Android software. The openness and flexibility of the platform has ensured its worldwide popularity, and niche apps can be placed and discovered by numerous users in niche application stores. Although smaller application stores have fewer visitors than Google Play, there’s quite a bigger chance for your app to become featured.
