Question

我想要的是： I want to run an application without LAUNCHER ICON and BraodCastReceiver running in the background. I searched And Make a DEMO for it

结果： Launcher ICON gone but when I reboot the phone BroadCastReceiver dosen't run. What is the possible Solution for this. I added the code what I am trying.

MainActivity

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Intent intent = new Intent(MainActivity.this, MyBroadcastReceiver.class);
        sendBroadcast(intent); 

        PackageManager p = getPackageManager();
        p.setComponentEnabledSetting(getComponentName(),PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
}

BroadCastReceiver类

public class MyBroadcastReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "hahahah", Toast.LENGTH_LONG).show();
    }

}

试试这个......

     protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_main);
     PackageManager p = getPackageManager();
     p.setComponentEnabledSetting(getComponentName(),PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
     finish();  
    }

如何隐藏在后台运行的启动器图标和BroadCastReceiver？
