If you know another way to provide crash log, please tell me.

Thank you

Without a crashlog it will be difficult to find the issue. I thought I found the issue and it doesn't crash anymore on my Android 6 device but apparently that was at best an incomplete solution.

If you are rooted there are several apps that read logfiles, otherwise you can use adb logcat from the Android NDK: https://developer.android.com/studio/command-line/logcat

BTW, since which version did these crashes start for you? Would that be 5.12, when the settings screens were moved to Kotlin?

Hello @johanw666

Following your instructions, i did retrieve a crash log using the free software Scoop available on F-Droid
Here it is

I've encountered this issue since 5.13, i didn't install 5.12 (and can't downgrade to it)

[johanw666]

Some investigation lead to seeing it uses the wrong Java version for some compile jobs, the crashed line in Quote.java pointed to Java 11 source. I set the JDK in Android Studio from internal to 1.8.0.192, this changes that behaviour and also fixed the (reoccurring) crash on my own Android 6 test device.

@Go-rom could you please test if this test release https://github.com/johanw666/Signal-Android/releases/tag/5.14.0.1-JW works for you?

Hello @johanw666

Thank you for your investigation, i just tested 5.14.0.1-JW and it works flawlessly. Thank you very much 👍

ps : i don't see anything regarding donation, don't hesitate to provide a way to do that

[johanw666]

@Go-rom I tried something else to fix the crash on Android 6 (changed the build file of libsignal, addded targetCompatibility) and that works on my Android 6 device. Could you please report if 5.14.2 works for you too?

Edit: it crashed again on my Android 5 machine, I have to go back to the original solution.

Hello @johanw666
5.14.2 has been installed yesterday and it's working fine

[johanw666]

Yes, but I reverted to my old solution and re-released.
