Hi guys,
 Recent days I was in busy with recent changes happening in android development. It was quite interesting to find that Google has brought up with lot more new API's and updates. Meanwhile was busy with building some recent projects even though I found my time to update the new API's available in SDK manager. As most curious thing was I just ended up coding with one of my new project and ready to test and build in eclipse IDE. After finishing downloading my new updated API's I found some recent errors with App-compact v7.jar over my LIB file. As usual was fixing it by correcting properties of the project and IDE even I found some hard to fix it. Even though I fixed the properties in eclipse by using each and every method I found that the dependencies were not matching with IDE resulting failure in adding LIB files.



Even though I tried every method to fix this error like 
  • "File->Import (android-sdk\extras\android\support\v7). Choose "appcompat" Project-> properties->Android. In the section library "Add" and choose "appCompat""
  • "-In Properties -> Android add the library, but uncheck "IsLibrary”. -In Android -> Project build tarjet check Android 4.0. -In "Java Build Path" -> Order and Export -> Unchecked the .jar library -Finally do a “Project -> Clean” both projects "
  • You should reinstall your Android Support Library by Android SDK Manager to get the complete android supportV7 library. The mediarouter library project dependency on the appcompat library project. So,after you have finished Step 1, you can follow Android Support Library v7: Error retrieving parent for item to fix this problem.
still it was unable to troubleshoot the error happened to the dependencies. Finally I referred our developer hub http://developer.android.com/ I found that some of the new API's dependencies are hard to work over in eclipse were as Google has announced their official IDE as ANDROID STUDIO.



After installing our new IDE all the dependency problem were solved regarding app.compact v7 and API 19, 20 and 21. Even our new IDE is literally awesome and it includes a lot of new features. So guys don't wait to get your new IDE. just download as early as possible.

Retrolambda in Android

Hi, folks, it's been a long time since we have discussed with new changes happening in the Android world. Today I would like to convey about a new feature which is used in Java 8  called Lambda functions. It's very interesting that Java is improving its coding structure with new updations. Hence Java 8 was a previous year release and currently, they have updated with Java 9 we are eagerly updating our technological deeds soon. In this blog post, I would like to give some detail about Lambda functions which was introduced in Java 8. Lambda function helps in making the declaration and instance creation much more simple and faster execution process. It also helps in reducing the line of codes which lead a developer much easier and approachable access to the specific program he wrote. As we know from the latest Android Studio updates IntelliJ is automatically handling the methods and instance creation in converting to the lambda expression. But some more method...

An android activity life cycle is most precious thing to keep in mind for each developer. The logic of an android app building comes under the open logic of activity life cycle. Here we can see on create, on resume,  on pause, on stop and on destroy methods (in the above specified life cycle). Each specified method are interlocked with each other at the runtime of an android application. Every method have equivalent role in implementing their function so as to perform without a runtime error. Of-course you might be thinking that generating a method without a proper function is impossible. Well let me say my point in saying that the proper use of timeline path of the activity life cycle can resist the runtime errors and can build a well quality application.
