如何在定制的OS手機（如Oppo，Vivo，MIUI）上處理FCM通知？

Question

我已經在Android應用中實現了FCM推送通知。 我在數據有效負載中獲得了所有通知JSON。 我還沒有在api上添加“ Notification”標簽。 因此，在所有狀態（前景/背景/已殺死）中，我僅在數據有效負載中收到了通知。

當應用程序為前台/背景/殺死時，在非定制OS手機（如Moto，Google等）上以及在所有國家/地區都可以正常工作。 但是問題是，當我在自定義OS手機（例如Oppo ， Vivo或MIUI）上進行測試時，通知僅在應用位於前景或后台（應用位於內存中）時到達，而在應用被“殺死”時未到達/出現（不是在記憶中）。

我該怎么辦？

無論如何，謝謝您的時間。

好吧，我已經找到了解決這個問題的方法。 為您的應用程序編寫一個自定義服務，該應用程序在后台連續運行，並編寫一個廣播接收器以終止該服務后重新啟動該服務。 這對我來說很好。 我已經在Vivo，Oppo，Redmi手機上對此進行了測試。 這是工作！

我的服務代碼如下-

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>

和我的MainActivity.java文件代碼一起啟動服務-

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);
}}

這是自定義操作系統提供商（例如MIUI，Vivo等）的悠久歷史，他們對電池優化策略非常嚴格，因此即使關閉應用程序，他們也不允許粘性服務重新啟動，這就是您選擇該操作系統的主要原因正在面對這個問題。 盡管您無法通過代碼執行任何操作來幫助您的用戶，但是您可以將他們帶到其Security Center並要求他們啟用auto-start功能。 為此，您必須添加以下代碼：

try {
    Intent intent = new Intent();
    String manufacturer = android.os.Build.MANUFACTURER;
    if ("xiaomi".equalsIgnoreCase(manufacturer)) {
        intent.setComponent(new ComponentName("com.miui.securitycenter", "com.miui.permcenter.autostart.AutoStartManagementActivity"));
    } else if ("oppo".equalsIgnoreCase(manufacturer)) {
        intent.setComponent(new ComponentName("com.coloros.safecenter", "com.coloros.safecenter.permission.startup.StartupAppListActivity"));
    } else if ("vivo".equalsIgnoreCase(manufacturer)) {
        intent.setComponent(new ComponentName("com.vivo.permissionmanager", "com.vivo.permissionmanager.activity.BgStartUpManagerActivity"));
    } else if("oneplus".equalsIgnoreCase(manufacturer)) { 
        intent.setComponent(new ComponentName("com.oneplus.security", "com.oneplus.security.chainlaunch.view.ChainLaunchAppListAct‌​ivity")); }

    List<ResolveInfo> list = context.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
    if  (list.size() > 0) {
        context.startActivity(intent);
        } 
    } catch (Exception e) {
        Crashlytics.logException(e);
}

此應用會將用戶帶到安全中心，在該中心您必須要求他們為您的應用啟用自動啟動功能。 現在，諸如whatsapp和instagram之類的應用程序沒有此類問題，但我不清楚原因。正如我在設備上看到的那樣，默認情況下，這些應用程序已啟用自動啟動。
