Hello Xda,
I Have created a simple apk and i want to add login/register feature to my app.
Thanks
We need more info as to what you're using.
IE: Any frameworks? Native?
Typically, how it's done is an HTTP request is made to a URL that returns JSON DATA.
I can't post links yet, else I'd link you to some tutorials, but, I would suggest Googling PHP login script, and a tutorial on JSON for whatever framework you are using.
If you let me know the details, I can create a simple example script that will help.
