Hi Neil,

    mFuelLevel = intent.getIntExtra ("FUEL_LEVEL", -1);

We want to set our mFuelLevel variable to the FUEL_LEVEL constant value. and we have to specify where we are calling the getIntExtra method from. In our case it is from the "intent"

Hey kevin,

the idea of passing data through intent is by key - value pair. since FUEL_LEVEL is our key, it will hold the value that was given to him.

now, to get that value in another activity, we ofcourse use the getIntent(); just like kevin did, for the purpose of organization, use the variable name that will hold the data that passed to the activity and assign him the value - in our case the getIntExtra, passing the KEY and giving a default value, in case you didnt get any value, or there was any kind of error.

just in case, please use Log code to show if you got the desired result in the log cat -

Log.i("Log", mFuelLevel);

hope that helps :)
