Android Login with JSON registration

For the first time to do Android, it may be a good demo faster than anything, but recently in the registration of Android login, found that the basic can not find what I want, but have to bite the bullet to do, fortunately do not pay, finally fix, also is to give themselves a confessed.
Structurally speaking, this code is not good, just a simple implementation of the registration login function, there is a need for the pot friends to the past. Contains full Android side and server side code and test JSON files, database.
Nothing to say, said more is all tears, these days are tired. Get a good night's sleep by sending out the code.
