问题
In my existing project i want to add ActionBar for older versions less than api-11. So i imported android-support-v7-appcompact with resources following the official site.Till here every thing works fine. When i extended ActionBarActivity to my MainActivity.java the following error occurred in console, please see the screen shot.
android:minSdkVersion="10"
android:maxSdkVersion="19"
android:targetSdkVersion="16"
Project Build Target is 4.1.2 . Java Compiler is set to 1.6. I am also using facebook sdk in my project, so i deleted android-support-v4.jar file from the project libs folder but error did not go. Finally clean and build the project. Any suggestions PLEASE. Thanks in advance.
