Hi @shashank-ADOBE ,

Thank you for reporting. I checked the code around these lines, and it does not look like a MAM issue. I.e. without MAM integration, your app is likely to see the same ANR. MAM is being in the stack trace only because we are a wrapper around the actual Android API call.

Do you have an app without MAM integration that you can check for a similar trace?

 at com.microsoft.intune.mam.client.app.offline.OfflineContentProviderBehavior.attachInfo (OfflineContentProviderBehavior.java:44)
  at com.microsoft.intune.mam.client.content.MAMContentProvider.attachInfo (MAMContentProvider.java:68)

MAMContentProvider.attachInfo is calling into OffineContentProviderBase.attachInfo, which just calls the app defined attachInfo method. This is the OffineContentProviderBase.attachInfo method:

    @Override
    public void attachInfo(final Context context, final ProviderInfo info) {
        mContentProvider.attachInfoMAM(context, info);
    }

Thanks for responding. Agreed & although we do not have an builds without Intune MAM but I did find this happening in general with several other clients here: https://issuetracker.google.com/issues/234116801

Will followup from there. Closing this one.
