Fatal Exception: java.lang.RuntimeException - App Crash on Android

[MSetnik]

The app is crashing on Android devices in production. We are not sure why and cannot trigger it in development, but it seems to be connected to the twilio-voice package

Fatal Exception: java.lang.RuntimeException

Our guess that rejecting a call via notification is triggering crash which should not be the issue.

any solution so far?

Hey @upal-factiiv do you have any additional crash logs to supplement the original poster? As much information as possible will help us out, thanks.

This seems to be the same crash called out here

#604

Try to set the enableProguardInReleaseBuilds to false in /android/app/build.gradle, it works for me

[domenic39]

@errorstudent thanks. Im not too familiar with that setting, do you know what that is doing to make the issue go away?

@errorstudent thanks. Im not too familiar with that setting, do you know what that is doing to make the issue go away?

Setting enableProguardInReleaseBuilds = false basically disables the shrinking/obfuscation step, so nothing gets stripped out — which is why the problem goes away.

You can follow this documentation https://www.twilio.com/docs/voice/sdks/android#set-up-proguard-rules if you want the enableProguardInReleaseBuilds = true.

Thanks for linking to this @errorstudent ! Looking at my expo project, it looks like proguard is turned off already by default.

Just to clarify, are you setting this in your application project or in the twilio sdk project?

If in your application project? Curious if you built a custom plugin to set it to make use of Expo CNG ?

Any code examples are much appreciated!

Thanks all for the additional info. I'll discuss with my Android teammate to see if/how proguard affects these crashing issues.

@domenic39 just wondering if that solution of setting enableProguardInReleaseBuilds = false works? Cause i already set it on prod and crashes still happened on my Android app
