There are generally two types of errors: syntax errors and logic errors. You have a logic error. This is something that android studio doesnt pick up on. why? because your syntax is properly coded.... but your logic is wrong and is returning a null. showing us the error log does nothing to help you, sir. perhaps show us your code? — letsCode, Jul 28 '17 at 15:23
Kindly edit your question, and include your code for `register` click event — boop_the_snoot, Jul 28 '17 at 15:32

make sure that the button has been correctly assigned with correct id of the corresponding xml. i.e. Button myRegisterBtn = (Button)findViewById(R.id.myRegisterBtn);//make sure the id within findViewById is located in the xml you inflated in your activity.

app stops immediately after i click register
