your myphonecall broadcastreceiver , declare activity. gives error.

05-13 05:55:33.031: e/androidruntime(1022): java.lang.runtimeexception: unable instantiate activity componentinfo{com.example.myphonecall/com.example.myphonecall.myphonecall}: java.lang.classcastexception: com.example.myphonecall.myphonecall cannot cast android.app.activity

declare following way.

<receiver android:name=".myphonecall" >         <intent-filter>             <action ...... />             <action ..... />         </intent-filter>     </receiver>
