The ANRs & crashes section of the Google Play Console has been recently updated to display more ANRs & crashes (automatically collected from users that have opted in).>
I managed to decrease occurrences of it by adding these lines to my Proguard file:
-keep class android.app.Application
-keep class <>.MyApplication
that may be shortened to:
-keep class * extends android.app.Application
According to android source code I suppose it fixed the first issue.
I also updated all my libs to the last versions (Google Play Services 11.0.2, support lib 25.4.0) that should have fixed the second one.
UPDATE: it doesn't fix the issue completely. I got far less occurrences but there are still some.
