Hello,
My B4A aplications that uses AdMob library crashes when running on Android 4.1 and 4.2 devices. But runs OK in android 5 or Android 6.
I searched the forum and found some questions about this problem with other librarues, but not a conclusive answer.
The same I´ve found at StackOverflow. It seem like the problem is with these Android versions.
The problem happens with other libaries too, as seen in the forum.
Someone know a workaround for this?
I use B4A 5.8. The Android support library jar is the most recent.
The code crashes at the instruction adview.LoadAd. I tried to use the TRY / CATCH to at least trap the error, but I think it doesn't worked. Only when running in these Android versions.
adHeight=50dip
adview1.Initialize2("Ad", "ca-app-pub-xxxxxxxxxxxxxxxxxxxxxxxx",adview1.SIZE_SMART_BANNER)
Activity.AddView(adview1, 0,0,100%x,adHeight)
adview1.BringToFront
Try
adview1.LoadAd
Catch
ToastMessageShow("AdMob LoadAd Error. Android Version.",False)
End Try
Testing in the IDE the logs shows:
