Hello everyone ! I just created a new app (react 16.11 and react-native 0.62) , installed react-native-webrtc and configure the android part acording to the docs (as i did for an other app that works well) but without even calling any method form the package the app open and close immediatly. Anyone run into that problem ? ---

Would be easier to debug if you could provide logs from logcat. Shouldn’t be more than opening the android project in Android Studio, hooking up the device, launch the app a few times, check the logs for the crash error. ---

If you’re experiencing crashing due to using a newer gradle version then you can fix that by adding `android.enableDexingArtifactTransform.desugaring=false` inside your gradle.properties file. ---

How can this work, if this property is experimental and unsupported? The current default value of this property - ‘true’. I tried your advice, but I got a new error “Native module WebRTCModule tried to override WebRTCModule.” I made rebuild, but this didn’t help in my case(Any ideas?) ![Снимок экрана 2020-05-12 в 20.57.54](https://global.discourse-cdn.com/free1/uploads/reactnativewebrtc1/original/1X/3c5b81c07ad373b6553f0ff1aebf2517bfb988fa.png) ---

Weird error. Seems almost like you’re trying to load the module twice. ---
