So, your mind is embedded with creativity to build a thirst quenching app for the users. Some great pictures coming in your mind where you can see unsurpassed downloads? Where are you stuck? Is it in learning to code a successful Android Application?
Learning is a never-ending process and if you have that hunger in you, no task is unreachable. Android Application Development can be a daunting task, especially if you are a beginner. Lots of in-depth knowledge is required to start on with the development process. Some of the terms which you might not be even familiar with pops up but special thanks to Google, which makes our task way easier. Take a deep sigh of relief and fasten your seatbelt for a big and a bumpy coding ahead.
Step 1: Selection of Operating System
An Operating System is the most important software that runs on a computer. It is a medium of communication between the programmer and the computer itself. Proper selection of OS (Operating System) depends upon the scope of your project. There is three major OS ruling the Internet world- Linux, Windows, and Mac.
Linux is the preferred OS by most of the developers, but if you are new to it, go for Windows Operating System. Once the selection has been done, you can go on to the next step of installation of the Android Studio.
Step 2: Downloading and Installing Android Studio
Android Studio is the most used ‘Integrated Development Environment’ owned by Google. IDE is a platform where you can see the codes that you write and view the results there itself. After downloading the Android Studio, you can just finish off the installation process to see a screen where you can run your codes.
A common editor can also be used to run the codes, but why to ignore the specialty of this IDE? It is specifically designed to code and Android Application.
Step 3: Downloading the Java Development Kit (JDK)
After the Android Studio has been downloaded, the next important software is the JDK. The programming language which will be used to develop the Android app will be JAVA. Therefore, to use the Android Studio, JDK needs to be installed which can be downloaded here. Follow the instructions carefully to install. Once it has been done, your Android Studio is ready to be launched.
Another deciding factor is the UI in which you want to see the output of your code. There are two options open for you- Emulator or the Real Time Device.
An Android Emulator is an Android Virtual Device which will look exactly the same as your Android device and can be used to run and test your code. If you have opted to test your code on a Real-Time Device, the Driver supporting it needs to be installed again.
Step 4: Starting your First Project
You are all set to start your new Android Studio Project. Enter the name of the project you are all the way waiting for and after successful completion, you can upload it to Google Play Store.
Naming your project should be smart enough because this will be the file which all the users will be seeing. While thinking about the application, you might have decided the platform on which it shall run, meaning; Phone or Tablet.
Step 5: The Starting Page for the Final Project
Once the app you are making, opens, you can see a message saying- “Hello World”. This is the smallest program which all the developers make while learning a new technology. From this, you can start coding your desired project in mind. It can be a Job Listing App or a Cab Booking app or maybe a Book Store even.
Finally Jumping into the Reality
Not all apps become successful and get great reviews. A bit of marketing along with User-friendly experience is something which needs to be focused the most. Also, JAVA is a language which requires a deep sense of knowledge. Practicing is the best possible way to come out with flying colors.

In the age of smart phones and tablets, Android powered devices have successfully managed to carve a unique identity for them. All the Android powered devices are famous for their user- friendly interface as well as the cheap apps and games available with them. Though these apps were already a part of many smart phones that came before Android, these were expensive enough that not everyone was able to afford them. With the introduction of Android powered smart phones and tablets in the market, this entire range of high end games as well as apps became more accessible to the common masses.
Android tablets have an advantage over other tablets available in the market. These tablets are powered with one of the most powerful and portable operating systems available today i.e. Android itself. These are highly customizable as well. The reliability as well as powerful features provided by Android is the reason why some of the automobile manufacturers in the world are also interested in it, so that they can find something useful and engaging for their customers.
Specifically speaking of Android tablets, it is a known fact that a whole new range of tablets have exploded in the digital market. Apart from this, the new range of applications and games that accompany these tablets are also commendable. However, all these choices can put people in a huge dilemma. To make it easier for everyone to easily and wisely invest in an Android tablet, below are some factors which should be kept in mind before investing in an Android powered tablet. In order to make a wise decision, scroll down and take a look at some of the points to be kept in mind before buying an Android tablet.
1. Purpose/ Usage of tablet
Interestingly, a wide range of tablets are available under the Android platform. These range from utility tablets for grownups to the user friendly and educative tablets for kids. The Kid’s Safe Tablet is especially designed for kids so as to assist them in various educative programs involved in their curriculum. It can be used for the purpose of playing games and solving puzzles as well. Also, there are the usual bigger and smarter tablets meant for grownups. These tablets are as efficient as a full- fledged laptop.
The perks of choosing separate tablets for you and your kids is that it will certainly reduce the wear and tear which kids often leave on their parent’s tablets. So, the first step is to determine the purpose for which you are planning to invest in an Android tablet.
2. Size of the tablet
After determining the purpose of investing in an Android tablet, the next step is to decide the size of the tablet. Luckily, Android powered tablets are available in a variety of sizes. One of the most interesting as well as advantageous fact about a tablet is that it is compact in size. The sleek design and smart built of a tablet is what makes them easy to carry and look after. While it is impossible to carry a PC around and since laptops are huge in size, tablets are what come to everyone’s rescue.
The 7 inch tablets from Android are way cheaper than many other tablets available in the market. But if you are interested in playing games and using apps on your tablet, those 10 inch tablets are simply perfect for you. While smaller tablets are easy to carry around, bigger ones have their share of advantages as well. For instance, watching movies and playing games is something that can be conveniently achieved on a big tablet. Since Android tablets can be highly customised, bigger tablets make the whole experience more enjoyable and mesmerising for the users. So, the second factor to be kept in mind while choosing the right Android powered tablet is the size of the tablet.
3. The right Android operating system
Like iOS, various versions of the Android operating system are also available. All these versions of Android have their own set of features. Starting from the very first version of Android i.e. Android 1.5 (Cup Cake), there are 8 more versions available. The most recently launched version of Android is the Android 4.4 (Kit Kat). It is entirely the buyer’s decision that which version of Android he/ she wants in his/ her tablet. Accordingly, their tablet will be performing all the functions which are offered within the scope of that particular version of Android.
Moreover, there are certain applications as well as games which are unique to each version and they may/ may not be upgradable to the higher ones. Hence, every buyer should be cautious while buying a tablet with Android 2.3 or below. The reason behind this is that these versions do not support Flash. It is advised to choose the appropriate version of Android wisely. This can be done based on the user’s preferences as well as the reasons behind buying a tablet.
4. The right manufacturer
Looking at the popularity and fan following of Android tablets in the market, there are few very potentially powerful tablet manufacturers in the digital world today. The dilemma arises because each of these tablets is worth putting your hands on. Manufacturers like Sony, Google, Samsung, etc have emerged as equally powerful suppliers of Android powered tablets in the world.
However, it may not be that difficult to choose between these tablets. The reason behind this is that each of these manufacturers has some additional features and may function differently as well. Hence, the only way to zero in on any Android tablet is by being sure about the features and specifications that you expect to be there in your tablet.
5. What’s your budget?
The cost of an Android tablet depends on the version of the Android operating system installed as well as the features offered by it. The various factors which contribute in the final price of a tablet include the operating system, features, built, design, utility as well as the size. While smaller tablets are definitely cheaper than the bigger ones, it solely depends on the user’s requirements and budget.
6. Does your tablet connect to the Android market?
Sadly, not every Android powered tablet can be connected to the online Android market. This is because Google does not have much control on Android. Once a new version of Android is released to the masses, there is nothing that Google can do. But Google certainly has the control over the entire Android market. Hence, older versions of Android such as Android 2.2 and below will never connect to the Android market. No doubt some apps will be available to you, but the majority of utility apps and games will be far out of your reach.
You must be wondering about the significance of buying an Android tablet if you cannot have access to all the apps and games in the Android market. Hence, this is another important factor to be kept in mind while buying any Android powered tablet.
7. Tablets may/ may not require a data plan
All Android tablets can be either sold with Wi-Fi connectivity or with 3G/ 4G wireless data access. Often it is seen that these tablets are sold at a discount price because of their collaboration with any cellular service provider. Before investing in any Android tablet, check if you are covered under the 2 years of payment over the price for which you are buying your tablet. Also, check the amount of data that you will be provided under this plan. It is always advised to go for a plan which is expandable in future.
8. Say no to Modified Androids
Similar to the modifications brought in Android user interfaces in different devices by their manufacturers, modifications can be brought in Android tablets as well. Often manufacturers state that it is a wonderful thing, but it also has some disadvantages.
The disadvantage is that these modified versions often act differently from their real versions. This may pose a difficult situation for people using the modified version of Android. Hence, you should always go for the real and original version of Android.
Investing in the right Android tablet is surely a difficult decision to make. But once you invest in the right tablet, there will be no looking back for you.

Time was when Google developer conferences buzzed around Google Maps, Web tool kit and so on. But from the last conference on the Limelight was on Android, and Chrome in that order. Perhaps the humongous opportunity resting in smartphones has sunk deep into Google. A fact acknowledged by Larry Page himself when he quipped that he would like to run the company via his smartphone.
Google has bought to integrate its other products with Android and update them in Android without having to update Android to match them in compatibility.
As mentioned in the previous paragraph, Android aficionados do see a silver lining out of the limited Android updates. Blogs are rife with how features introduced from this edition onwards do not needlessly need an update in the OS. It provides fodder for agreement as the basic premise for changing an OS 'version is to enable it to play all the applications, be it ancient or futuristic. The various versions and configurations (of individual mobile hardware companies like Samsung, HTC, Sony etc) of Android were creating considerable firewalls to updating even the proprietary Google apps; apps that provide the quintessential Android experience. Google via its feature update, effectively tackles the problem of fragmentation as Google+, Gmail, Google Maps, Google Play, apps that are present in Android from versions Froyo onwards a well as Google Music All access that is all in versions Froyo onwards without need of an update. It sees the issue of fragmentation has been hopefully nailed.
Android Studio : this update does have the name android stamped on it! Meaning, it is Android specific. News is that Google plans to introduce Android Studio to replace the existing Eclipse developer environment for Android apps. Google collaborated with JetBrains to create the Android Studio. Of course this development has some loose ends to tie up, yet Google feels this IDE when launched would help Android developers increase their productivity. Here's how it could help:
- It combines capabilities of Maven and Ant to build flexible and variedly flavored solutions.
- Excellent code editing capabilities including finding inline resources and Android specific customizations. It is boosted by advanced editor UI that enables drag-drop of widgets, simulate output view in different hardware configurations and even preview while editing in XML.
- Provides deep analytical capability to identify all sorts of bugs
- Provided wizards based on preset templates and also access to other Google services.
- Provides for easy migration of projects from Eclipse (as export) or import into Studio (of existing Eclipse IDE projects).
Google has, like Android OS, made Android Studio free and open source which could be the sweetener.
Google Play : Android developers can use the Google Play services to procure the desired APIs to construct maps, games or social media (read Google+) on Android devices (mobiles or tablets).
Gaming : entertainment is moving to handheld devices by droves putting a premium on providing the same user experience as in computer / gaming console. Google has stepped up the user experience by introducing the following features:
- Leaderboards: a maximum of 100 leaderboards, both public and social, is provided to enable developers engage users by letting them compare scores with other players. Leaderboards are created automatically for daily, weekly, monthly or customized versions.
- Rewards system: developers can reward users for engaging in the game by providing standard or incremental achievements that can be viewed in a user interface. The can use the developer consoles to control the achievements.
- Google provides the Cloud Saving APIs to save game status and settings on cloud.
- Developers can allow users to invite other players to the game or play with random users with the maximum limit pegged at 4.
Google facilitates the development of location aware apps by providing the following APIs:
Geofencing APIs : this API is used to define geographical boundaries. It also provides the following options:
- to create alert filters for customers exiting a particular area
- alter updates of location in response to locomotion habit (like walking, riding or driving) of the customer (see Activity recognition API )
- add or delete geographic boundaries
Fused location provider: this API uses underlying schema to provide the apt results to your query on locations, even complex level queries. It is quick, versatile and utilizes less battery power.
Activity recognition provider : this API uses power sensors to detect the customer's current activity, for example, driving, walking, riding idling etc. This is used in tandem with the Geofencing API to provide the apt updates to the customer.
Single Sign-on via Google+ : accounting for the fact that users change mobile devices often and that these devices may run different OS, Google provides the API to sign in via Google+ in any device. This obliterates the need to make services like Google Wallet, Games, Plus device specific. There are libraries for these services that respond to the auto sign request using their method.
Google Cloud Messaging : Google has made it possible to register apps using its Single Method. It also provides for messaging to 3rd party servers via its bi-directional messaging (XMPP) using Cloud Connection Server. Users can synchronize notifications across devices using Google's APIs for user notification.
Google Play Developer Console : Google has been supporting its huge Android developer community and this year's conference added the fillip to it.
App Translation Service : The localization support team from Google enables you to avail translation services for a nominal fee and post the strings to be translated in the language of your choice. If required it prompts the apt localization sting in the app graphics, APK or the About product sections. This eventually helps developers reach out to a wider audience.
Analytics and Monetization : Keep a track on the performance of an app just become easier. Google Play and Google Analytics provides complementary services like app views and downloads and engagement metrics.
Google has introduced the order status API to let developers view the order status of an in-app from their servers. It has also decided not to charge test accounts for in-app test purchases.
Alpha and Beta testing and Staged Rollouts : Google has added the alpha-beta testing to let developers split their apps into two alternatives, alpha and beta, and get them tested by different user groups. If needed, testers for Google+ can also be added to test these versions.
Developers can sinceforth roll-out updates only, to their apps to a batch of users to gauge their feedback. Developers can set the percentage of users who would be using the update.
Perhaps for those expecting Android only chants at the Google I / O 2013, it might be a dampener. But for those familiar with the maverick that Google is will vouch the shrewd way it's gone about indulging Android community. Updates to Google Play, its services, launch of the Android Studio, cloud messaging and ability to sign into Google services sans OS or hardware requirements are significant game changers. In short, it is about updating features sans the need to update OS.
Google's I / O 2013 was an Android winner, in a hush hush way!

The operating system is being optimized for hands-free operations. We bring you 5 new features on Android Wear 2.0 for Android App Development.
A new App Launcher
The app launcher has been redesigned to accommodate the round screen format and look uncluttered. Device interaction has been made user-friendly towards the new app launcher changes. Pushing the side button will display apps in an arc and a new action drawer at the bottom of the display will provide context-specific actions similar to the ones we find on the smartphone.
The new update will unclutter the interface, especially for spherical interface with the well placed cards. Smaller icons are displayed instead of huge messages and the notifications are easier manage with a progress bar on the bottom display showing how many cards are left in the stack. When the user raises the watch to activate it, the notification card will be first folded up before it is hidden. Bottom to top swiping action will enable the user to normally view the notifications. The cards themselves have been redesigned with light text on a black background and dark text with white background. The two options are offered as a battery saving moving and lessen intrusion of bright notification.
More on Fitness
Android is becoming fitness friendly and with new smartwatches, Google is exploring fresh scope in fitness applications. The new Wear update comes with Google Fit integration and has a new feature for automatic activity recognition. User can open relevant apps for running, walking or bike reading and sensing the activity the relevant app will open up. User can also launch fitness playlist to listen to music of their choice without turning on the device. Music apps can be accessed directly from the homescreen, without turning on the device. The Google Fit app itself can now automatically detect activity and log it. Data sharing between devices and apps have been overhauled.
Messaging is a limited activity on the tiny screen as of now and with the new keyboard and voice texting options it is likely to get better with version 2.0. a small keyboard can be swipedscreen to type messages and handwriting recognition allows user to write single letters or join words for messaging. Smart answers from Gmail will be accessible with three reasonably responses as prompts to send quick reply to contact. By tapping o the message user can access options to respond to message.
With the new version, users can now type text directly into the watch, which is a welcome update. There is support for handwriting recognition and Swype-style inputs with traditional typing option. Users can dictate their responses, although in the preview version only short messages are currently working smoothly. However, considering the fact that the wearable device format is for quick actions, this should not pose a big problem. One can access saved responses on the Wear which prompts three contextually relevant responses. This is a smart integration from Gmail's smart replies.
The new version is likely to be released in the fourth quarter of this year and will integrate with the new Android app development Nougat and come on new devices. The developer preview is available for installation and testing the new features on applications, but improvements are still awaited before the release date to fine-tune the new system.

Are you an Android phone user, but are unaware of most of the features it provides? Do you want to discover safer and interesting features on your phone? Go through this article to know some of the Android tips and tricks, which will be useful for you.
Most of the people in the present world use Android phones daily, for calling, messaging and more. Android is the mobile operating system, which most of the phone manufacturing companies use in their phones. There are lots of features, rather than calling and messaging to be examined. Explore the hidden features and many time-saving tricks in your gadget.
The basic problem, a phone user face, is the battery issues. Most of the Android phones have an inbuilt power strip option, which when activated, provides faster disconnection of all the phone ‘s battery thus killing the applications. Another feature is that, you can be the developer of your own phone settings. Go to the ‘Settings’, select ‘About phone’ option and tap seven times on your phone’s ‘Build number’.
An onscreen countdown will be shown on the screen, which will be followed by a command telling that you are now a developer and ‘Developer option’ will be shown just above the ‘About phone’ option.
This ‘Developer option’ can be utilized well to reduce the lagging of your Android phone as well.
By reducing the ‘Window animation scale’, ‘Animator duration scale’ and ‘Transition animation scale’ in ‘Developer option’, from 1x to 0.5x, your phone may actually feel faster than before. Now you can get a grip on those annoying app notifications by long pressing on the notification of the app, on notification bar, which will show an information icon on the right corner. Tapping on this icon gives you option to prioritize your notifications. You can block unwanted apps, hide private information or select priority mode for most prior app.
To zoom in and out your Google maps while driving, all you need to do is a just double tap on the spot and swipe upward or downward. This tip will help you to avoid the problem of pinching your phone screen while managing your phone to stay in place, all while driving.
Nowadays kids use their parents’ phone more frequently. To keep away your kids from getting into unsafe games, adult contents or accidental access to your bank, this feature will be of great help. Go to ‘Setting’ then to ‘Security’ and enable the ‘Screen pinning’ option. Open the app you wish to pin and protect, then press the overview button to pin the app.
Another interesting feature is the inbuilt games on the Android phones. In ‘Settings’, select ‘About phone’ and tap several times on the device’s ‘Version number’ to get this feature.
