java - Oppo、Vivo、MIUI等定制OS手机如何处理FCM通知？

Question

我已经在我的 Android 应用程序中实现了 FCM 推送通知。我在数据有效负载中获得了所有通知 JSON。而且我在 api 上“未添加”“通知”标签。所以在所有状态(前景/背景/杀死)中，我只收到数据有效负载中的通知。

它在 Moto、Google 等非定制操作系统手机上运行良好，在所有状态下，当应用处于前台/后台/终止状态时。但问题是，当我在定制的操作系统手机上测试时，如 Oppo、Vivo 或 MIUI 通知仅在应用程序处于前台时到达或背景(应用程序在内存中)，当应用程序被“杀死”(不在内存中)时未到达/出现。

我该怎么办？

无论如何，感谢您的宝贵时间。

好吧，我已经找到了解决这个问题的方法。为您的应用程序编写一个在后台持续运行的自定义服务，并编写一个广播接收器以在服务被终止后重新启动该服务。这对我来说很好。我已经在 Vivo、Oppo、Redmi 手机上测试过了。它正在工作!

我的服务代码如下--

public class MyService extends Service
{

private static final String TAG = "MyService";


@Override
public void onStart(Intent intent, int startId)
{
    // TODO Auto-generated method stub
    super.onStart(intent, startId);
}

@Override
public boolean onUnbind(Intent intent) {
    return super.onUnbind(intent);
}


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

@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
    //call to onTaskRemoved
    onTaskRemoved(intent);
    //return super.onStartCommand(intent, flags, startId);
    Toast.makeText(this, "Service Started!", Toast.LENGTH_SHORT).show();

    return START_NOT_STICKY;
}

@Nullable
@Override
public IBinder onBind(Intent intent)
{
    return null;
}

@Override
public void onDestroy()
{
    Toast.makeText(this, "Service Destroyed!", Toast.LENGTH_SHORT).show();
    Intent intent = new Intent("com.myapp.startservice");
    //Intent intent = new Intent("android.intent.action.BOOT_COMPLETED");
    intent.putExtra("yourvalue", "torestore");
    sendBroadcast(intent);
    super.onDestroy();

}



@Override public void onTaskRemoved(Intent rootIntent)
{
    Log.e("onTaskRemoved", "Called!");

    //thread = new Thread(this);
    //startThread();

    /*Intent alarm = new Intent(this.getApplicationContext(), MyBroadCastReceiver.class);
    boolean alarmRunning = (PendingIntent.getBroadcast(this.getApplicationContext(), 0, alarm, PendingIntent.FLAG_NO_CREATE) != null);
    //if(!alarmRunning)
    {
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 0, alarm, 0);
        AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        if (alarmManager != null) {
            alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime(), 10000, pendingIntent);
        }
    }*/

     //send broadcast to your BroadcastReciever
    Intent intent = new Intent("com.myapp.startservice"); //unique String to uniquely identify your broadcastreceiver
    //Intent intent = new Intent("android.intent.action.BOOT_COMPLETED");
    intent.putExtra("yourvalue", "torestore");
    sendBroadcast(intent);

     //intent to restart your service.
    Intent restartServiceIntent = new Intent(getApplicationContext(), this.getClass());
    restartServiceIntent.setPackage(getPackageName());

    PendingIntent restartServicePendingIntent = PendingIntent.getService(getApplicationContext(), 1, restartServiceIntent, PendingIntent.FLAG_ONE_SHOT);
    AlarmManager alarmService = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
    if (alarmService != null) {
        alarmService.set(
                AlarmManager.ELAPSED_REALTIME,
                SystemClock.elapsedRealtime() + 1000,
                restartServicePendingIntent);
    }

    super.onTaskRemoved(rootIntent);

}}

我的 BroadcastReceiver 如下 --

public class MyBroadCastReceiver extends BroadcastReceiver
{

@Override
public void onReceive(Context context, Intent intent)
{
    Log.e("MyBroadCastReceiver", "onReceive");

    //if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction()))
    {
        Intent service = new Intent(context, MyService.class);
        context.startService(service);
        Log.e("BootCompleteReceiver", " __________BootCompleteReceiver _________");

    }
}}

我的 AndroidManifest.xml 文件如下--

 <!-- My Service -->
    <service
        android:name=".Service.MyService"
        android:exported="false"
        android:stopWithTask="false" />


    <!-- My Broadcast Receiver -->
    <receiver
        android:name=".Service.MyBroadCastReceiver"
        android:enabled="true"
        android:exported="false">

        <intent-filter>
            <action android:name="com.myapp.startservice" />
            <action android:name="android.intent.action.BOOT_COMPLETED"/>
            <action android:name="android.intent.action.ACTION_EXTERNAL_APPLICATIONS_AVAILABLE"/>
            <category android:name="android.intent.category.DEFAULT"/>

        </intent-filter>

    </receiver>

还有我的MainActivity.java文件代码启动服务---

public class MainActivity extends AppCompatActivity
{

Button btnStopService;

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

    btnStopService = findViewById(R.id.btnStopService);

    //get FirebaseToken
    getToken();

    //start Service
    startService();



    btnStopService.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(MainActivity.this, MyService.class);
            stopService(intent);
        }
    });

}


private void getToken()
{
    FirebaseId firebaseId=new FirebaseId();
    String token_firebase=firebaseId.getFireBaseToken();
}


private void startService()
{

    Intent myIntent = new Intent(this, MyService.class);
    PendingIntent pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);
    Log.e("TAG", "++++++++++222222++++++++");
    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
    Calendar calendar = Calendar.getInstance();
    // calendar.setTimeInMillis(System.currentTimeMillis());
    //calendar.add(Calendar.SECOND, 10);
    if (alarmManager != null) {
        alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
    }

    Toast.makeText(this, "Start Alarm", Toast.LENGTH_LONG).show();

}

private void s()
{
    Intent intent = new Intent(this, MyService.class);
    startService(intent);
}}
