片段活动在项目点击时崩溃

Question

I used "empty activity" but I am changing with "Navigation drawer activity". Now, when I click on my item "ACTIVA 128", my application stop running and I don't know how to fix it.

Thank you.

Answer 1

Change this code

String code1[] = {spinn_code[0], spinn_code[2], spinn_code[3]};

with

String code1[] = {spinn_code[0], spinn_code[1], spinn_code[2]};

You got this error because there is no third item of spinn_code array.
