Admob library causes ANR problems to the App

[Денис Жигало]

Hello! 

I am seeing increasing number of ANR's in my Developer Console caused by Google Mobile Ads SDK.

I'm using the latest 

'com.google.android.gms:play-services-ads:15.0.1' 

for Banner Ads.

targetSdkVersion - 27

In some circumstances Admob library causes ANR errors like this:

Hi,

Thank you for providing the error logs captured.

I'm assuming that this is not reproducible on your end locally, however, if you were able to reproduce it later, then providing us a sample project and replication steps will be really helpful. On the other hand, in your last comment, are you implying that the crash was triggered from MobileAds.initialize()?

To help with our investigation, could you provide to us privately (using Reply privately to author option) the following information?

• Information on the affected Devices
• Complete ANR or crash reports from your Developer Console
• If available, Crashlytics link

Regards,

Ivan Bautista

Yes, this is not reproducible on my end locally. 

ANR was triggered from my.app.Application.onCreate line MobileAds.initialize().

Information on the affected Devices and android versions on picture.

Hi,

Thank you for the additional information provided.

I will pass this on to the rest of the team and we will update you accordingly in this thread.

Hi,

I just want to check back with you if you are still encountering the same ANRs even with our latest SDK version (17.1.1 as of this writing). However, please note that starting 17.0.0, there is a required step when initializing the Mobile Ads SDK.
