Jitsi react native error

Hello,
i want to integrate jitsi for react native android in to my project.
i used jitsi version 2.1.1
i added the following codes (as the documentation said) in to my project.

const blacklist = require('metro-config/src/defaults/blacklist');

module.exports = {
  resolver: {
    blacklistRE: blacklist([
      /ios\/Pods\/JitsiMeetSDK\/Frameworks\/JitsiMeet.framework\/assets\/node_modules\/react-native\/.*/,
    ]),
  },
};

project.ext.react = [
    entryFile: "index.js",
    bundleAssetName: "app.bundle",
]

import androidx.annotation.Nullable; // <--- Add this line if not already existing
  ...
    @Override
    protected String getJSMainModuleName() {
      return "index";
    }

    @Override
    protected @Nullable String getBundleAssetName() {
      return "app.bundle";
    }

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        maven {
            url "https://maven.google.com"
        }
        maven { // <---- Add this block
            url "https://github.com/jitsi/jitsi-maven-repository/raw/master/releases"
        }
        maven { url "https://jitpack.io" }
    }
}

implementation(project(':react-native-jitsi-meet')) {
      exclude group: 'com.facebook.react',module:'react-native-locale-detector'
      exclude group: 'com.facebook.react',module:'react-native-vector-icons'
    }

after going to the page where is jitsi , after setTimeOut the app closed.
Can you help me to integrate it in the right way.
Thanks.
