我正误差：

解决方案
您应该扩展SherlockFragmentActivity代替SherlockActivity
- I am using Actionbarsherlock library, This is a project to perform drawer operation
- I have also ensured i don't mix compatibility packages, still i am getting this error

In the line ::
android.support.v4.app.FragmentTransaction ft = getSupportFragmentManager().beginTransaction().replace(R.id.frame_container, fragment).commit();
I am getting error as::
The method getSupportFragmentManager() is undefined for the type MainActivity
解决方案
You should extend SherlockFragmentActivity instead of SherlockActivity
