What i have did is like this - I have android-support-v7-appcompat.jar as well as android-support-v4.jar in android java build path.

In some answer in SO suggested that unchecked Android dependencies in java build path i tried it also but nothing is working for me.

In my gen folder there are two package one for goole-play-service-lib and another for my project , and in my project package under gen folder only trwo file is there R.java and BuildCOnfig.java. Anybody have any suggestion please suggest me

Answer 1

Import the support.v7.appcompat as a library project in your workspace and attach it with your project.

Try this,it will work for sure. if you still face any issue, do comment.

Answer 2

You have to just delete your appcompat and re-import it to eclipse and change its android built property to highest api configuration. Clean your project, copy-paste R file in gen package and change project build path to highest api level like api-21.

This will solve your problem.

Answer 3

In "android-support-v7-appcompat" project:

-Delete “android-support-v7-appcompat” from Package explorer.
-Import again and check “Copy into workspace”
-In Properties -> Android -> in Project build target, uncheck Android 2.2 and check Android 4.1.2
-In Java build path, uncheck if you have any .jar library, and uncheck the Dependence

and finally this is what you need to do.
