Android crash while loading flagged by Play Store Pre-Launch Report

Expo SDK
1

The Android Play Store is now flagging up crashes in its pre-launch report on 3 out of the 9 Android devices tested. Looking at the video it is during loading while the splash screen is visible.

The main difference is I just upgraded to SDKv21, are there known issues with this?

Crash as follows:

I’ve upgraded to SDKv22 but still getting crashes in the Play Store Pre-Launch report: The first release had no crashes in Google’s pre-launch report. The second release crashed on 1 out of 9 devices tested.

I had 4 out of 9 crash on SDKv21 before that. Looks fairly random.

I’ve also seen a crash on first running a brand new installed APK on my own phone. Could it be related to fetching the JS first time run? The recent Play Store report crash follows the logcat line:

Do not have cached source file for https://d1wp6m56sqw74a.cloudfront.net/%40crasher%2Fapp%2F1.0.4%2F06107da86759ea357eea8bb48bf0b65f-22.0.0-android.js

There are similar reports on Github: https://github.com/expo/expo/issues/779

Anyone else seeing similar?

The crash in your original post looks like it’s happening when React Native loads your JS bundle. Perhaps there’s some character or string of characters in your bundle that’s causing this, like non-ASCII characters (though those should be fine in theory).

Hi,

Thanks for the reply @ide. Might that affect it randomly between runs if it’s just loading the bundle in the first place?

The latest one is still at JSStringCreateWithUTF8CString+104 but the call stack is different (and abi22 this time):
