I can’t reproduce the error with our AdmobSample from https://github.com/vplayplugins/AdMobSample on any of our test devices. Does this happen with this project too or only in your custom project?
As the errors are AdMob SDK internal errors we probably need more information:
- Which Android build target (architecture)?
- Does it happen on all of your Android devices you have available for testing?
- Are you using multiple AdMob items within your project? Do they have different adunit ids?
- Are you using test ads (with testDeviceIds) or “real” ads?
