I link this 2 log in api with my app and it is already done in debug mode(connect my phone with my computer and press run). When I build apk and put it to my phone and run , it doesn't work like in debug mode.
It alerts that 1. windows excption index out of bound 2. hash key doesn't match (google result error code: 10)
I think the first problem isn't the true problem. I think the second is the problem so I go to see the SHA-1 on my computer. It's a match with SHA-1 in developergoogle.
I run app in debug mode.
It works well. The result of google api is error code:0 (not error)
Can anyone tell me what this problem is and how to solve it ?
