Describe the bug

When initializing the video room.initVideoRenderer, crash logs:

If I switch the version of webrtc-sdk it will work fine

I switched 114.5735.05 to 104.5112.10

implementation 'io.github.webrtc-sdk:android:104.5112.10'

I guess it is because webrtc-sdk is packaged using java11. Can this problem be solved?

[davidliu]

I'm unable to repro this crash on my Android 9.0 device with the sample apps in the repo. Try adding the following to your app/build.gradle file in the android section:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

I'm unable to repro this crash on my Android 9.0 device with the sample apps in the repo. Try adding the following to your app/build.gradle file in the android section:

compileOptions {
  sourceCompatibility JavaVersion.VERSION_1_8
  targetCompatibility JavaVersion.VERSION_1_8
}

It is invalid because I always have JavaVersion.VERSION_1_8 in compileOptions of app/build.gradle

Although Android 8 has a small market share, the main target group of our project is middle-aged and elderly people, and most of their devices have low configurations, so there are relatively more mobile phones equipped with Android 8. It is certain that this type of problem will occur on the Android 8 platform of vivo or MEIZU, but there is no such problem with Livekit SDK version 1.2.0. As I said above, when I run Livekit When SDK (1.6.0) is packaged locally and uses io.github.webrtc-sdk:android:104.5112.10, it will not have this problem.

I learned through google search that it is most likely caused by Java11. The following are the search results. I hope it can help you find and solve the problem. Thank you very much!

It is an issue from other projects and has nothing to do with livekit, but it is very similar to the problems we currently encounter when using livekit. I hope it can help: https://github.com/react-native-webrtc/react-native-webrtc/issues/1310

Does setting the targetCompatibility to targetCompatibility JavaVersion.VERSION_11 work for you?

[wzJun1]

Sorry, due to project policy, I cannot modify targetCompatibility, and our project has been fixed to JavaVersion.VERSION_1_8 over the years.

Does setting the targetCompatibility to targetCompatibility JavaVersion.VERSION_11 work for you?

[wzJun1]

Currently I use io.github.webrtc-sdk:android:104.5112.10 and livekit 1.6.0. Everything is fine for the time being, not particularly urgent. But I still hope to use the latest version

[davidliu]

Can you see if the sample apps crash in the same way as well?

[wzJun1]

OK, Wait a minute, I'm going to test

[wzJun1]

There is no problem with the demo, which is really strange. We just upgraded a version of livekit sdk, and this happened.

I'll check the code again.

[wzJun1]

But as soon as I switch to version 1.2.0, Android 8 will work fine. It's amazing

[davidliu]

Can you upload a sample project reproing the issue? It's likely a difference in build.gradle settings.

[wzJun1]

I found that this problem occurs when using livekit sdk 1.6.0 on Android 8 or 9 when the gradle version is lower.

for example:

Android gradle plugin version = 4.2.2
Gradle version = 6.7.1

There will be problems using livekit sdk 1.6.0 at this time.

But there is no problem using livekit sdk 1.2.0 at this time.

Due to problems with our project, it may not be possible to modify the Gradle version, so is there a better solution?
