We also have the same issues reported on Google Play console, roundly 50 effected users per day. It's the top reason that makes our app crashes. It looks like OneSignal did not running on background. Unfortunately I couldn't reproduce on my environments.

[anilmercan]

We are getting same ANR in some devices . I attached the log output. Not all of our users getting ANR . Our OneSignal Version is 3.6.2

@mitonline Do you have a web view that is starting with your app? I see webview on the main thread.

@baole @anilmercan Can you attach a full ANR log like above?

[jkasten2]

We made some large changes to the SyncService which I believe should fix this issue in PR #470. This will released it this week under the version 3.8.2 which you can watch for on our Releases Page

Some ANRs are due to two instances of the main launcher Activity being created. Make sure your Activity can handle this, or better yet add android:launchMode="singleTop" to your Activity in your AndroidManifest.xml to be safe. See Google's docs on Actives for more details.
