Question

我发现使用停留在后台的应用程序很难启动新活动。这是我的代码：

public class App1 extends Activity{

    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        registerReceiver(batteryInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
    }

    private BroadcastReceiver batteryInfoReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context c, Intent i) {
            Toast.makeText(getApplicationContext(), "TEST", Toast.LENGTH_LONG).show();
            Intent intent = new Intent("App2.intent.action.Launch");
            intent.putExtra("startedByApp", true);
            startActivity(intent);
        }
    }

    @Override
    public void onBackPressed() {
        moveTaskToBack(true);
    }
}


public class App2 extends Activity{

    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Toast.makeText(getApplicationContext(), "TEST 2", Toast.LENGTH_LONG).show();
    }
}

当App1在前台时，它可以正常工作。当App1在后台（moveToBack）时，它显示“TEST”，但它没有启动App2（我的屏幕上没有“TEST 2”。

伙计们，你能帮助我吗？

您需要一个标记intent.addFlag(Intent.FLAG_ACTIVITY_NEW_TASK);

活动移至开始活动
