Well if you look at your code logically, you can see that it makes no sense. You can see you are starting an intent and then getting the intent within the onclick which makes no sense. You only use getExtra when you are on the activity where the intent was sent to.

All you need need to do is put the key-value pair into the intent

intent.putExtra("FUEL_LEVEL", mFuelLevel);

Im not sure why you put -1 to be honest. As you can see above, I am putting the key and the value (mFuelLevel) into the intent. You want to put that line right before you startActivity().
