我写了一个示例来学习 BroadcastReceiver..但是当我重启我的手机时，应用程序崩溃了。这是我的源代码和 manifest.xml:
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public class BootCompleteReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context,"Boot Complete",Toast.LENGTH_LONG).show();
}
}
}
