java.lang.RuntimeException: Unable to instantiate activity ComponentInfo

Question

I was trying to run a sample code While launching the application in the android 1.5 emulator , I got these errors.... Any one have some hint..?

ERROR from LogCat:<

Answer 1

For me it was different from any of the above,

The activity was declared as abstract, That is why giving the error. Once it removed it worked.

Earlier

     public abstract class SampleActivity extends AppcompatActivity{
     }

After removal

     public class SampleActivity extends AppcompatActivity{
     }
