Configuration #

Android #

Gradle

Set dependencies of build tools gradle to minimum 3.6.3:

dependencies {
    classpath 'com.android.tools.build:gradle:3.6.3' <!-- Upgrade this -->
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

Set distribution gradle wrapper to minimum 5.6.4.

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip <!-- Upgrade this -->

Add Java 1.8 compatibility support to your project by adding the following lines into your build.gradle file:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

AndroidManifest.xml

Jitsi Meet's SDK AndroidManifest.xml will conflict with your project, namely the application:label field. To counter that, go into android/app/src/main/AndroidManifest.xml and add the tools library and tools:replace="android:label" to the application tag.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="yourpackage.com"
    xmlns:tools="http://schemas.android.com/tools"> <!-- Add this -->
    <application 
        tools:replace="android:label"  
        android:name="your.application.name"
        android:label="My Application"
        android:icon="@mipmap/ic_launcher">
        ...
    </application>
...
</manifest>

Minimum SDK Version 21

Update your minimum sdk version to 21 in android/app/build.gradle

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "com.harryluu.jitsi_meet_mb_example"
    minSdkVersion 21 //Required for Jitsi
    targetSdkVersion 28
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}

Proguard

Jitsi's SDK enables proguard, but without a proguard-rules.pro file, your release apk build will be missing the Flutter Wrapper as well as react-native code. In your Flutter project's android/app/build.gradle file, add proguard support

buildTypes {
    release {
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        signingConfig signingConfigs.debug
        
        // Add below 3 lines for proguard
        minifyEnabled true
        useProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

Then add a file in the same directory called proguard-rules.pro. See the example app's proguard-rules.pro file to know what to paste in.

Note
If you do not create the proguard-rules.pro file, then your app will crash when you try to join a meeting or the meeting screen tries to open but closes immediately. You will see one of the below errors in logcat.

If you don't provide any flag to JitsiMeetingOptions, default values will be used.
If you don't provide a flag in featureFlags in JitsiMeetingOptions, its default value will be used.
We are using the official list of flags, taken from the Jitsi Meet repository

REMARK about Call integration Call integration on Android (known as ConnectionService) has been disabled on the official Jitsi Meet app because it creates a lot of issues. You should disable it too to avoid these issues.

Listening to Meeting Events #

Events supported

NameDescription
onConferenceWillJoinMeeting is loading.
onConferenceJoinedUser has joined meeting.
onConferenceTerminatedUser has exited the conference.
onErrorError has occurred with listening to meeting events.

Per Meeting Events

To listen to meeting events per meeting, pass in a JitsiMeetingListener in joinMeeting. The listener will automatically be removed when an
onConferenceTerminated event is fired.

await JitsiMeet.joinMeeting(options,
  listener: JitsiMeetingListener(onConferenceWillJoin: ({message}) {
    debugPrint("${options.room} will join with message: $message");
  }, onConferenceJoined: ({message}) {
    debugPrint("${options.room} joined with message: $message");
  }, onConferenceTerminated: ({message}) {
    debugPrint("${options.room} terminated with message: $message");
  }));

Global Meeting Events

To listen to global meeting events, simply add a JitsiMeetListener with
JitsiMeet.addListener(myListener). You can remove listeners using
JitsiMeet.removeListener(listener) or JitsiMeet.removeAllListeners().

@override
void initState() {
  super.initState();
  JitsiMeet.addListener(JitsiMeetingListener(
    onConferenceWillJoin: _onConferenceWillJoin,
    onConferenceJoined: _onConferenceJoined,
    onConferenceTerminated: _onConferenceTerminated,
    onError: _onError));
}

@override
void dispose() {
  super.dispose();
  JitsiMeet.removeAllListeners();
}

_onConferenceWillJoin({message}) {
  debugPrint("_onConferenceWillJoin broadcasted");
}

_onConferenceJoined({message}) {
  debugPrint("_onConferenceJoined broadcasted");
}

_onConferenceTerminated({message}) {
  debugPrint("_onConferenceTerminated broadcasted");
}

_onError(error) {
  debugPrint("_onError broadcasted");
}

Title bar #

When Jitsi Meet is opening, the title bar will reflect:

  • For Android: the android:label tag in the AndroidManifest.xml in
  • For iOS: the Bundle name in Info.plist For IOS - Support added for Xcode 11.4 Ensure in your Podfile you have an entry like below declaring platform of 11.0 or above. platform :ios, '11.0' Also in Info.plist add the following This will ensure the right permissions are configured in your project.
