Android service not restarting in lollipop

Question

In my application, I use location based service in background. So I need to restart my service when it gets destroyed.

But I got this message in logcat

Answer 1

import android.app.Notification;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.os.Environment;
import android.os.IBinder;
import android.support.v7.app.NotificationCompat;

import java.io.File;
import java.io.IOException;

import activity.MainActivity;
import activity.R;
import fragment.MainFragment;

public class MyService extends Service {
    public static final int NOTIFICATION_CODE = 1;


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


    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        startForeground(NOTIFICATION_CODE, getNotification());
        return START_STICKY;
    }

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

    @Override
    public void onDestroy() {
        stopForeground(true);
        super.onDestroy();
    }

    @Override
    public boolean stopService(Intent name) {
        return super.stopService(name);
    }


    /**
     * Create and return a simple notification.
     */
    private Notification getNotification() {    
        Notification notification;
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
        builder.setColor(getResources()
                        .getColor(R.color.material_deep_teal_500))
                .setAutoCancel(true);

        notification = builder.build();
        notification.flags = Notification.FLAG_FOREGROUND_SERVICE | Notification.FLAG_AUTO_CANCEL;

        return notification;
    }


}

You can modify this code to accomodate your needs but this is the basic structure to start foreground service. Which restarts if gets killed.

Finally I achieved with help of Evernote JobService

Github link - https://github.com/evernote/android-job

Step 1: Add evernote jobservice dependency

implementation 'com.evernote:android-job:1.3.0-alpha03'

Step 2: Create DemoJobCreator.java class

public class DemoJobCreator implements JobCreator {

@Override
@Nullable
public Job create(@NonNull String tag) {
    switch (tag) {
        case DemoSyncJob.TAG:
            return new DemoSyncJob();
        default:
            return null;
    }
}
}

Step 3: Create DemoSyncJob.java class

public class DemoSyncJob extends Job {

public static final String TAG = ">>>> job_demo_tag";

@Override
@NonNull
protected Result onRunJob(Params params) {
    // run your job here
    Log.d(TAG, "onRunJob: ");
    if(!isMyServiceRunning(this.getContext(), TestService.class)){
        Intent intent=new Intent(context,TestService.class);
        context.startService(intent);
    }
    scheduleJob();
    return Job.Result.SUCCESS;
}

public static void scheduleJob() {
    new JobRequest.Builder(DemoSyncJob.TAG)
            .setExecutionWindow(2_000L, 2_000L)
            //.setPeriodic(900000) -> recommended. but it will work after 15 min (if you used this no need scheduleJob(); inside onRunJob();)
            .build()
            .schedule();
 }

 public static boolean isMyServiceRunning(Context context, Class<?> serviceClass) {
    try {
        ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
            if (serviceClass.getName().equals(service.service.getClassName())) {
                return true;
            }
        }
    }catch (Exception e){
        Log.e(TAG, "isMyServiceRunning: ",e );
    }
    return false;
  }
  }

Step 4: In your Application file (If not available create it) add following line in onCreate()

 JobManager.create(this).addJobCreator(new DemoJobCreator());

Step 5: Finally start JobService in your Activity

DemoSyncJob.scheduleJob();

This JobService will check service running or not (every 2 second) If service not running it will restart the service.

Disclaimer : This may be not right solution. But it will 100% working.

I hope it helps atleast anyone in future.

Answer 3

how you check issocketalive that socket is connected or not ? if sockettimeoutexception is generated then try to on set getinputstream and getoutputstream. other issue that may be socket not closed properly. So if possible then put your socket code here

Answer 4

Your code in onTaskRemoved is preventing the system to run the killProcess commands. The delay on Kitkat is caused by using alarmService.set, which is inexact from API 19. Use setExact instead.

If you have a service that you want to keep alive, it is recommended that you attach a notification to it and make it foreground. That way the likeliness of it being killed would be lowered.

Answer 5

You can restart it by using a BroadcasteReceiver which handles the broadcast sent from onDestroy() of your service.

How to do this:

StickyService.java

public class StickyService extends Service
{

    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }

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


    @Override
    public void onTaskRemoved(Intent rootIntent) {
         super.onTaskRemoved(rootIntent);
         sendBroadcast(new Intent("IWillStartAuto"));
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        sendBroadcast(new Intent("IWillStartAuto"));
    }

}

RestartServiceReceiver.java

public class RestartServiceReceiver extends BroadcastReceiver
{

    @Override
    public void onReceive(Context context, Intent intent) {
    context.startService(new Intent(context.getApplicationContext(), StickyService.class));

    }

}

Declare the components in manifest file:

    <service android:name=".StickyService" >
    </service>

    <receiver android:name=".RestartServiceReceiver" >
        <intent-filter>
            <action android:name="IWillStartAuto" >
            </action>
        </intent-filter>
    </receiver>

Hope this will help you.

Answer 6

this worked for me

Add this attribute in android:allowBackup="false" in manifest file in application tag.

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">

<application
    android:allowBackup="false"
    tools:replace="android:allowBackup">

</application>
</manifest>
