I am still new to android development, as well as Java. I was following a
tutorial on how to make a login, and I am using some of their code right
now, but I can't get this to work at all. I am getting a lot of errors.
The errors I am getting are:
Method does not override method from its superclass
Class "ProcessRegister" must either be declared abstract or implement
abstract method 'doInBackground(params) in AsycTask
NOTE: THE SAME GOES FOR class NetCheck
Hopefully someone can help me, because I have no clue what I am doing wrong
here...
