Empty constructor exception in DeviceAdminReceiver

Question

E/AndroidRuntime(27856): java.lang.RuntimeException: Unable to instantiate receiver com.inc.statusbar.Statusbar$DeviceAdminSampleReceiver: java.lang.InstantiationException: can't instantiate class com.inc.statusbar.Statusbar$DeviceAdminSampleReceiver; no empty constructor 

I already tried to call the default constructor of the DeviceAdminReceiver class, but to no avail. A constructor exception also gives the same error. DeviceAdminSampleReceiver Class Definition -

 public class DeviceAdminSampleReceiver extends DeviceAdminReceiver { public DeviceAdminSampleReceiver() { super(); } @Override public void onEnabled(Context context, Intent intent) { super.onEnabled(context, intent); } @Override public CharSequence onDisableRequested(Context context, Intent intent) { super.onDisabled(context, intent); return "admin_receiver_status_disable_warning"; } @Override public void onDisabled(Context context, Intent intent) { super.onDisabled(context, intent); } }
