Solution 1:

Please manage required permission for marshmallow.

First you add this permission in manifest file

<uses-permissionandroid:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permissionandroid:name="android.permission.ACCESS_FINE_LOCATION" />

After in your activity First declare two variable like this,

privatestaticfinalintREQUEST_CODE_PERMISSION=1;
 StringmPermission= Manifest.permission.ACCESS_FINE_LOCATION;

After in onCreate method

if(Build.VERSION.SDK_INT>= 23) {

        if (checkSelfPermission(mPermission) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(MainActivity.this,
                    new String[]{mPermission,
                    },
                    REQUEST_CODE_PERMISSION);
            return;
        }

        else
        {
            *here manage your code if permission already access
        }
    }

}

Put this code in seperate java file named LocationBackGroundService.java and call it in your MainActivity like this startService(new Intent(this, LocationBackGroundService.class)); and don't forget to add it in menifest like this <service android:name="LocationBackGroundService"></service>
