Summary

Hi,

I have spend 2 days tried to fix this error but it keeps appearing whatever I try.

Here is a related StackOverflow question

It works when I remove ffmpeg plugin and packages from npm modules, and it works on iOS

I have tried

• Downgrading to v2.0.0 and expo v45
• Modifying build.gradle and app/build.gradle according to the SO answers
• Fresh install with just ffmpeg plugin
• 2 Emulator and 1 real device
• Expo prebuild --clean, ./android/gradlew clean, deleting node_module at each try

I am out of solutions now

Config Plugin

@config-plugins/ffmpeg-kit-react-native

What platform(s) does this occur on?

Android

SDK Version

~46.0.13

Reproducible demo

https://github.com/top-kat/expo-ffmpeg-kit-example

Run

• yarn install
• yarn prebuild
• yarn android

We have the same problem, we also have have ffmpeg installed.

I found a way how to solve this issue. So basically this ffmpeg plugin changes android minSdkVersion to version 24 and it causes this error. What we do, is we use lts version for android, which requires minSdkVersion 16 and we patched this config plugin to not update minSdkVersion. Here is the patch-package patch:

Getting this same error, trying to use the plugin: https://github.com/react-native-webrtc/react-native-webrtc

I'm on versions: @config-plugins/react-native-webrtc": "^5.0.0", "expo": "~47.0.9", "react-native-webrtc": "^106.0.1"

Here's a screenshot from my android emulator:

After messing with this all day I abandoned react native altogether in favor of two native apps. Honestly I think I can develop my app quicker without dealing with all these layers of abstraction.
