无法从应用程序android中的前台服务接收活动中的数据

问题描述

我正在制作一个应用程序，它读取在一个活动中通过蓝牙发送的数据，然后将其重定向到前台服务，该服务将意图发送到将处理数据的另一个活动。我知道我在活动代码上的广播接收器代码中遗漏了一些东西。

如果有人可以给我建议或帮助我处理数据。到目前为止没有崩溃。我是 android studio 的新手，任何帮助都会很棒！

*** 这是前台服务的代码***

public class ForegroundService extends Service {

public static final String CHANNEL_ID = "ForegroundServiceChannel";

@Override
public void onCreate(){
    super.onCreate();

    createNotificationChannel();
    Intent notificationIntent = new Intent(this,MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this,notificationIntent,0);
    Notification notification = new NotificationCompat.Builder(this,CHANNEL_ID)
            .setContentTitle("Foreground Service")
            .setContentIntent(pendingIntent)
            .build();

    startForeground(1,notification);
}

@Override
public int onStartCommand(Intent intent,int flags,int startId) {
    //super.onStartCommand(intent,flags,startId);

    String input = intent.getStringExtra("inputExtra");
    Log.i("Tag",input);
    sendData(input);
    createNotificationChannel();
    Intent notificationIntent = new Intent(this,CHANNEL_ID)
            .setContentTitle("Foreground Service")
            .setContentText(input)
            .setContentIntent(pendingIntent)
            .build();
    startForeground(1,notification);
    return START_NOT_STICKY;
}
@Override
public void onDestroy() {
    super.onDestroy();
}
@Nullable
@Override
public IBinder onBind(Intent intent)
{
        return null;
}

private void sendData(String input){
    Log.i("Tag","inside sendData");
   
    Intent intent = new Intent();
    intent.setAction("com.example.Pillwoah.sendbroadcast");
    intent.setFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
    intent.putExtra("inputExtra",input);
    sendbroadcast(intent);
}

private void createNotificationChannel() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel serviceChannel = new NotificationChannel(CHANNEL_ID,"Foreground Service Channel",notificationmanager.IMPORTANCE_DEFAULT);
        notificationmanager manager = getSystemService(notificationmanager.class);
        manager.createNotificationChannel(serviceChannel);
    }
}

}

*** 这是活动代码***

public class MainActivity5 extends AppCompatActivity {

protected static final String TAG = "TAG";

TextView dataText;

broadcastReceiver receiver;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main5);

    Log.i(TAG,"data sending");
    configureReceiver();
}

class DatabroadcastReceiver extends broadcastReceiver {
    @Override
    public void onReceive(Context context,Intent intent) {
        String message = "broadcast intent detected " + intent.getAction();
        Log.i(TAG,message);
    }
}

private void configureReceiver(){
    IntentFilter filter = new IntentFilter();
    filter.addAction("com.example.Pillwoah.sendbroadcast");
    receiver = new DatabroadcastReceiver();
    registerReceiver(receiver,filter);
}

}
