使用ResultReceiver在应用程序之间进行Android通信

Question

我有两个申请。第一个应用程序是简单的服务应用程序，它在后台完成一些工作。我决定使用IntentService。

@Override
protected void onHandleIntent(Intent intent) {

    if (intent == null) {
        return;
    }

    ResultReceiver callbacks = intent.getExtras().getParcelable(EXTRA_CALLBACKS);
    ...

在我的情况下，第二个应用程序必须使用第一个使用Intent的IntentService。

public class SendActivity extends AppCompatActivity {


private ResultReceiver callbacks = new ResultReceiver(new Handler()) {
    @Override
    protected void onReceiveResult(int resultCode, Bundle resultData) {
        super.onReceiveResult(resultCode, resultData);
        System.out.println(String.format("%d, %s", resultCode, resultData.toString()));
    }
};

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

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Intent intent = new Intent(Intent.ACTION_SEND);
            intent.setType("text/plain");
            intent.putStringExtra("TEXT", "Text");
            intent.putExtra("CALLBACKS", callbacks);
            intent.setClassName("com.service", "com.service.MyIntentService");
            startService(intent);
        }
    });
}

我得到了：
