RE: [google-admob-ads-sdk] Fatal Exception: java.lang.IllegalStateException at (MediaPlayer.java) and etc.

[Mobile Ads SDK Forum Advisor Prod]

Hi there,

Thank you for reporting this issue to us. Could you please try using our sample ad unit for native ads and see if you will encounter the same crash issue? If the crash would occur, this will rule out that this is related to bad creatives.

I saw a similar issue reported to us with the same error logs you shared. They found out by removing the problematic creative the crash issue stopped.

Also note that I’m going to mask your post (please. see below) on this thread as it contains sensitive information.

Hi,

We've initially reached out to  publishe...@google.com to determine if it's a case of "bad" creative. They are served using the standard GAM native video format. They checked the creative and observed on a test apk we provided. They eventually concluded that the problem seems to be with the media player of GMA SDK android.media.MediaPlayer.native_invoke(MediaPlayer.java)) rather than a problem in the ad itself and suggested we reached out to this forum. 

Please see attached stack traces and screenshots from our Crashlytics account.

Our app xxxxxxxxxxxxxxx /  SDK 19.5.0 installed, I beleive?

The crashes coincide with us running the aforementioned native video ad. 

Please let me know if you need more info.

Hi Sherwin,

We are using GAM as opposed to AdMob and plus, our implementation is native style (fluid) and not custom rendering, so which sample ad unit ID of yours has a native video ad?

Hi,

Thank you for responding back to us regarding this issue. You can check out our documentation here . Which will give you the information about what test ad unit we would be using.

Hi William,

Okay, that doesn't help at all. Nowhere on the page will you find any test ad unit that specifically contains a native video ad.

To recap our problem:

We've initially reached out to  publishe...@google.com to determine if it's a case of "bad" creative. They are served using the standard GAM native video format. They checked the creative and observed on a test apk we provided.

Our app (com.olx.pk) has afma-sdk-a-v204204999.204102000.1 /  SDK 19.5.0 installed, I beleive?

The crashes coincide with us running the aforementioned native video ad.

Hi there,

Thanks for your message. For your reference, here’s our sample ad unit ids:

/6499/example/native or /6499/example/native-video

Let me know if this works for you and if you will encounter any crash issues.

Thanks. 

To make the testing on par with our production set up, could you please confirm if the native video sample is using:

1. An MP4 video file

2. Has third-party impression tracker with cachebuster macro. For info, we are using the below for our creative:

Hi,

I hope you're doing well.

I just want to circle back with regard to the crashes that you're encountering with GMA SDK android.media.MediaPlayer.native_invoke(MediaPlayer.java)), can you confirm if you're still encountering this in your end? If yes, I would suggest to try our latest version, as there are changes made in the new version. Feel free to reach our to us if you still encountering this.
