I'm really a newbie so I just watch tutorials. I'm having an issue about the location. I'm using a switch to go online/offline but when I pressed the switch, my app crashes.Here is the code

I tried to debug it and it always points out the mCurrent = mMap.addMarker part. I tried a lot but it always crashes. Please help me fix it. Thankyou
also this is the logcat
