Meshenger Version 4.3.8. Calling from Android 6.0 to Android 11.0 crashes the app on Android 11.0

[barkoder]

To reproduce.

0. Install Meshenger 4.2.8 on Android 6.0 device and Android 11.0 device and scan QR codes and Add to Contacts.

1. Notice Green Circle indicator on both devices.

2. Call from Android 6.0 to Android 11.0 .

3. Meshenger on Android 11.0 exits immediately, and the Android 6.0 device throws an error.

Also after it errors, when I reopen Meshenger on the Android 11.0 device, the indicator on both the Android 6.0 device and 11.0 device doesn't turn green automatically. I have to open the app switcher on the Android 6.0 device, click on Meshenger again to get the contact indicators on both devices to turn green.

Also calling from Android 11.0 to the Android 6.0 device immediately crashes the app on the Android 11.0 device.

Also even after Meshenger crashes on the Android 11.0 device, the contact indicator(for the Android 11.0 device) on the Android 6.0 device continues to stay green, when it should turn red immediately.

Hi, are you using a dedicated hotspot / access point? If one of the devices creates a hotspot, then it would be a known problem.

[barkoder]

I can confirm that hotspot is off on both devices. I'm using my Local Wifi to get the devices to see each other.

The current problem is that I do not have an Android 6 phone for testing.

I got this error on Android 6 with 4.3.1

Caused by: java.lang.ClassNotFoundException: Didn't find class "java.util.Optional" on path: DexPathList[[zip file "/data/app/d.d.meshenger-1/base.apk"],nativeLibraryDirectories=[/data/app/d.d.meshenger-1/lib/arm64, /data/app/d.d.meshenger-1/base.apk!/lib/arm64-v8a, /vendor/lib64, /system/lib64]]

[mwarning]

@iddq what Meshenger release is this? Please also try Meshenger 4.3.0 and the 4.3.2-pre (from here https://github.com/meshenger-app/meshenger-android/releases/tag/v4.3.1)

[iddq]

4.3.2 is ok on Android 6. what was the solution? did you remove Optional class?

[mwarning]

@iddq 4.3.1 uses a self compile WebRTC, maybe other build flags are needed. In general I like to not have to compile WebRTC myself. That 4.3.2-pre package uses WebRTC compiled by some other open source project.

Using 4.3.8 .

For the first time I got the app working. I can call between Android 6.0 and 8.1 successfully. Yay!

However calling from Android 11.0 still immediately crashes the app on Android 11.0. Calling from Android 6.0 to 11.0 also crashes the app on Android 11.0 .

No more errors on Android 6.0 like it was in 4.2.8

I'm willing to share any debug logs from the Android 11.0 device via email if that would help, @mwarning .

Thanks.

@barkoder feel free to send the logs to moritzwarning@web.de. But you can also attach them here if that is OK for you.

Thanks.

[mwarning]

@barkoder thank you, I will check the logs later.

[mwarning]

The problem seems to be that RingtoneManager.getActualDefaultRingtoneUri() calls android.media.RingtoneManager.setRingtonesAsInitValue() on Samsung devices and throws a

java.lang.SecurityException: d.d.meshenger was not granted this permission: android.permission.WRITE_SETTINGS.

[iddq]

Is it in the initRinging function?

[mwarning]

Is it in the initRinging function?

yes

[mwarning]

Looks like this is a known problem for some samsung phones: https://stackoverflow.com/questions/74849517/calling-getactualdefaultringtoneuri-requires-write-settings-permission

[mwarning]

I pushed a fix that I came up with yesterday. In my opinion, Meshenger should not change the default ringtone. As such now a fallback ringtone is used ("Orion" from LineageOS) and a warning is displayed briefly.

@barkoder thank you very much for the logs!

This issue might be fixed now with the latest release, please test.

[barkoder]

@mwarning

It works now. Thank you very much!
