Here I have implemented functionality to read messages of incoming push notifications using Text-To-Speech. I created a separate service class for it which works fine and a

Answer 1

From the API level 26, android restricted background service access. You can solve this by starting your service as a foreground.

I had the same issue with my one project and i have fixed it by using below code.

In YourService.class

private static final String NOTIFICATION_CHANNEL_ID_DEFAULT = "my_flow_notification_channel_default";

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

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID_DEFAULT)
                .setOngoing(false).setSmallIcon(R.drawable.ic_notification).setPriority(Notification.PRIORITY_MIN);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
            NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID_DEFAULT,
                    NOTIFICATION_CHANNEL_ID_DEFAULT, NotificationManager.IMPORTANCE_LOW);
            notificationChannel.setDescription(NOTIFICATION_CHANNEL_ID_DEFAULT);
            notificationChannel.setSound(null, null);
            notificationManager.createNotificationChannel(notificationChannel);
            startForeground(1, builder.build());
        }
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // TODO: 
     return START_STICKY;
    }

To Start Service

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
     ContextCompat.startForegroundService(context, new Intent(context, YourService.class));
else
     context.startService(new Intent(context, YourService.class));

To Stop Service

stopService(new Intent(getActivity(), YourService.class));

In Your AndroidManifest.xml

Add this permission

<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />

Add this inside Tag.

<service
   android:name=".service.YourService"
   android:enabled="true"
   android:exported="true" />

Hope this help.. :)
