Android Question AdMob crashes on Activity_Pause

[andyr00d]

Hi,

Not sure what I did wrong, but for some reason my app will crash with a NullPointerException when my app is paused (inactivity). It's failing in the Activity_Pause sub.

I'm calling it in Activity_Create and the ad is loaded with no problems... I don't know what's going on :/

Sub Activity_Pause (UserClosed As Boolean)

AdView1.Pause

End Sub

Please post the full error message from the logs.

Hi @Erel

In this case, when I pushed the power/lock button on my phone while my app was running the error appeared.

** Activity (settings) Pause, UserClosed = false **

It wasn't doing this initially after I added AdMob, and I can't think of anything I changed to make this happen... any ideas?

Thanks,

Try it in release mode. Do you get the same error?

 

[andyr00d]

It doesn't seem to occur in release mode, is there anyway to fix it running in debug mode?

 

[Erel]

Can you send me your project (File - Export as zip) to erel@basic4ppc.com?

 

[Rusty]

Did you ever solve this? I'm getting the same error.
Code is already working and deployed, I'm just stepping through (debug) existing and working code...
Thanks,

PS it works in release mode, but not in Debug mode...
One thing else that might be important, I am starting an activity from within the MAIN Activity_Create function...

 

[Erel]

If it only happens in debug mode then the problem is most probably in the debugger. If you like send me the project and I'll test it here.
