Hello Backendless team!

I checked other answers but didn’t realy understand how can I solve this problem. I am trying to keep the current user logged in after restarting the app but I get the error in the attached photo. I highlighted the relevant code snippet.

Kasim

Hi Kasim,

The code you wrote looks reasonable.

Could you please grab the latest build of our library and try with it:
https://github.com/Backendless/Android-SDK/blob/master/out/backendless.jar

if you get an exception, please post the complete stack trace.

Regards,
Mark

Hi Mark!

Thanks for quick reply. I have this line in my gradle file and nothing else. Where should I put this file?

compile 'com.backendless:android:1.16'

Hi Kasim,

You’re using a super old version of the library. Try changing it to this first and see if it works:

compile ‘com.backendless:backendless:3.0.8.2’

Thank you Mark!

I think you should place a new line with newest gradle version somewhere in the README.md on github :slight_smile:

Have a nice day!
