[Yanis Biziuk]

We have a lot of ANR reports in google play console
Most of all start from MobileAds.initialize

Of cource we call MobileAds.initialize(context) { status -> ... } from the main thread

Is it allowed to init library from another than the main thread?

It's very difficult to reproduce it, this ANRs I only see in google play console. Usually, this ANR is happening with `slow` devices.

I can see that zzfjl.java (get) method should work with not a main thread. This is a root of the problem I think.

Hi there,

I'm afraid that we're left with not much of an option here as we'll need a detailed debug information from a device where it's observed in order to actually make any progress in diagnosing this. The only way for us to investigate further is by reproducing the issue locally. Could you provide the following details as well via Reply to author or a direct, private reply to mobileads...@gmail.com?

• App ID
• Ad Unit ID
• Affected devices
• occurrence percentage of the ANR

I have tested with 19.6.0 version of ads, and no problem with ANR!

@mobileadssdk I have sent info to provided email 

[Mobile Ads SDK Forum Advisor]

Hi Yannis,

Thank you for sending over the additional information. I was able to download the sample app and run it. While I do not see the error messages that you showed. I do in fact see errors which I have included for you to look over. From what I have seen regarding things similar to this. It would look like the way you are setting the redirect from the XML is not set up properly. So you are going to get crashes from that. When looking at the R type error with the URL cookies question is what I believe is causing the possible issue.

Hi William,

We haven't send any sample app. Can you please clarify what exactly did you check?

Hi Mikhail,

Thank you for the response. In looking back over the messages. I did see your response with the attached files. But, I have to apologize as I also saw another user regarding an issue that was similar to yours in our emails and mistook it as yours. Once we get the sample we will test it further and see what we can find.

Hi William,

Just to reiterate on Mikhail's initial point, obviously the main problem is high ANR rate. I think Mikhail sent a Stack trace for ANRs, will this be sufficient or do we require additional information.

[Omar Soussa]

Hi Team, 

Do we have any update on this open case?

Thanks,

Omar

Hi Omar,

I work with William and will assist you. I brought this to my team and we will get back to you as soon as possible. To help solve this, could you give us a sessions per ANR ratio, devices and OS versions this is occurring on and full traces of all threads?

Hi,

 

I hope you're doing well.

 

I just want to circle back on this. Can you confirm if you're able to turn the initialization optimization flag? If you haven't yet tried it, we suggest to use it as it mentioned that starting from Google Mobile Ads (GMA) SDK version 21.0.0, you can enable optimized SDK initialization and ad loading to improve the overall responsiveness of ads and help prevent "Application Not Responding" (ANR) errors on your app.
