Jitsi Meet SDK for Android

Build your own, or use a pre-build SDK artifacts/binaries

Jitsi conveniently provides a pre-build SDK artifacts/binaries in its Maven repository. When you do not require any modification to the SDK itself, it's suggested to use the pre-build SDK. This avoids the complexity of building and installing your own SDK artifacts/binaries.

Use pre-build SDK artifacts/binaries

In your project, add the Maven repository https://github.com/jitsi/jitsi-maven-repository/raw/master/releases and the dependency org.jitsi.react:jitsi-meet-sdk into your build.gradle files.

The repository typically goes into the build.gradle file in the root of your project:

allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url "https://github.com/jitsi/jitsi-maven-repository/raw/master/releases"
        }
    }
}

Dependency definitions belong in the individual module build.gradle files:

dependencies {
    // (other dependencies)
    implementation ('org.jitsi.react:jitsi-meet-sdk:+') { transitive = true }
}

Build and use your own SDK artifacts/binaries

1. Install all required dependencies.

2. Create the SDK-release assembly, by invoking the following in the jitsi-meet project source:

   cd android/
   ./gradlew :sdk:assembleRelease
   

   When this successfully executes, artifacts/binaries are ready to be published into a Maven repository of your choice.

3. Configure the Maven repositories in which you are going to publish the artifacts/binaries during step 4.

   In the file android/sdk/build.gradle modify the line that contains "file:${rootProject.projectDir}/../../../jitsi/jitsi-maven-repository/releases"

   Change this value (which represents the Maven repository location used internally by the Jitsi Developers) to the location of the repository that you'd like to use.

4. Publish the Maven artifact/binary of Jitsi Meet SDK for Android in the Maven repository configured in step 3:

   ./gradlew :sdk:publish
   cd ../
   

5. In your project, add the Maven repository that you configured in step 3, as well as the dependency org.jitsi.react:jitsi-meet-sdk into your build.gradle file. Note that it's needed to pull in the transitive dependencies:

   implementation ('org.jitsi.react:jitsi-meet-sdk:+') { transitive = true }
   

Generally, if you are modifying the JavaScript code of Jitsi Meet SDK for Android only, the above will suffice. If you would like to publish a third-party react-native module which Jitsi Meet SDK for Android depends on (and is not publicly available in Maven repositories) continue below.

6. Create the release assembly for each third-party react-native module that you need, replacing it's name in the example below.

   ./gradlew :react-native-webrtc:assembleRelease
   

7. Configure the Maven repositories in which you are going to publish the artifacts/binaries during step 8.

   In the file android/build.gradle (note that this is a different file than the file that was modified in step 3) modify the line that contains "file:${rootProject.projectDir}/../../../jitsi/jitsi-maven-repository/releases"

   Change this value (which represents the Maven repository location used internally by the Jitsi Developers) to the location of the repository that you'd like to use. You can use the same repository as the one you configured in step 3 if you want.

8. Publish the Maven artifact/binary of each third-party react-native module that you need, replacing it's name in the example below. For example, to publish react-native-webrtc:

   ./gradlew :react-native-webrtc:publish
   

   Note that there should not be a need to explicitly add these dependencies in your project, as they will be pulled in as transitive dependencies of jitsi-meet-sdk.

Using the API

=======

Jitsi Meet SDK is an Android library which embodies the whole Jitsi Meet experience and makes it reusable by third-party apps.

First, 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
}

To get started, extends your android.app.Activity from org.jitsi.meet.sdk.JitsiMeetActivity:

package org.jitsi.example;

import org.jitsi.meet.sdk.JitsiMeetActivity;

public class MainActivity extends JitsiMeetActivity {
}

Alternatively, you can use the org.jitsi.meet.sdk.JitsiMeetView class which extends android.view.View:

package org.jitsi.example;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import org.jitsi.meet.sdk.JitsiMeetView;

public class MainActivity extends AppCompatActivity {
    private JitsiMeetView view;

    @Override
    public void onBackPressed() {
        if (!JitsiMeetView.onBackPressed()) {
            // Invoke the default handler if it wasn't handled by React.
            super.onBackPressed();
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        view = new JitsiMeetView(this);
        view.loadURL(null);

        setContentView(view);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();

        view.dispose();
        view = null;

        JitsiMeetView.onHostDestroy(this);
    }

    @Override
    public void onNewIntent(Intent intent) {
        JitsiMeetView.onNewIntent(intent);
    }

    @Override
    protected void onResume() {
        super.onResume();

        JitsiMeetView.onHostResume(this);
    }

    @Override
    protected void onStop() {
        super.onStop();

        JitsiMeetView.onHostPause(this);
    }
}

JitsiMeetView

The JitsiMeetView class is the core of Jitsi Meet SDK. It's designed to display a Jitsi Meet conference (or a welcome page).

dispose()

Releases all resources associated with this view. This method MUST be called when the Activity holding this view is going to be destroyed, usually in the onDestroy() method.

getDefaultURL()

Returns the default base URL used to join a conference when a partial URL (e.g. a room name only) is specified to loadURLString/loadURLObject. If not set or if set to null, the default built in JavaScript is used: https://meet.jit.si.

getListener()

Returns the JitsiMeetViewListener instance attached to the view.

isPictureInPictureEnabled()

Returns true if Picture-in-Picture is enabled; false, otherwise. If not explicitly set (by a preceding setPictureInPictureEnabled call), defaults to true if the platform supports Picture-in-Picture natively; false, otherwise.

isWelcomePageEnabled()

Returns true if the Welcome page is enabled; otherwise, false. If false, a black empty view will be rendered when not in a conference. Defaults to false.

loadURL(URL)

Loads a specific URL which may identify a conference to join. If the specified URL is null and the Welcome page is enabled, the Welcome page is displayed instead.

loadURLString(String)

Loads a specific URL which may identify a conference to join. If the specified URL is null and the Welcome page is enabled, the Welcome page is displayed instead.

loadURLObject(Bundle)

Loads a specific URL which may identify a conference to join. The URL is specified in the form of a Bundle of properties which (1) internally are sufficient to construct a URL (string) while (2) abstracting the specifics of constructing the URL away from API clients/consumers. If the specified URL is null and the Welcome page is enabled, the Welcome page is displayed instead.

Example:

Bundle config = new Bundle();
config.putBoolean("startWithAudioMuted", true);
config.putBoolean("startWithVideoMuted", false);
Bundle urlObject = new Bundle();
urlObject.putBundle("config", config);
urlObject.putString("url", "https://meet.jit.si/Test123");
view.loadURLObject(urlObject);

setDefaultURL(URL)

Sets the default URL. See getDefaultURL for more information.

NOTE: Must be called before (if at all) loadURL/loadURLString for it to take effect.

setListener(listener)

Sets the given listener (class implementing the JitsiMeetViewListener interface) on the view.

setPictureInPictureEnabled(boolean)

Sets whether Picture-in-Picture is enabled. If not set, Jitsi Meet SDK automatically enables/disables Picture-in-Picture based on native platform support.

NOTE: Must be called (if at all) before loadURL/loadURLString for it to take effect.

setWelcomePageEnabled(boolean)

Sets whether the Welcome page is enabled. See isWelcomePageEnabled for more information.

NOTE: Must be called (if at all) before loadURL/loadURLString for it to take effect.

onBackPressed()

Helper method which should be called from the activity's onBackPressed method. If this function returns true, it means the action was handled and thus no extra processing is required; otherwise the app should call the parent's onBackPressed method.

This is a static method.

onHostDestroy(activity)

Helper method which should be called from the activity's onDestroy method.

This is a static method.

onHostPause(activity)

Helper method which should be called from the activity's onPause method.

This is a static method.

onHostResume(activity)

Helper method which should be called from the activity's onResume or onStop method.

This is a static method.

onNewIntent(intent)

Helper method for integrating the deep linking functionality. If your app's activity is launched in "singleTask" mode this method should be called from the activity's onNewIntent method.

This is a static method.

onUserLeaveHint()

Helper method for integrating automatic Picture-in-Picture. It should be called from the activity's onUserLeaveHint method.

This is a static method.

JitsiMeetViewListener

JitsiMeetViewListener provides an interface apps can implement to listen to the state of the Jitsi Meet conference displayed in a JitsiMeetView.

JitsiMeetViewAdapter

A default implementation of the JitsiMeetViewListener interface. Apps may extend the class instead of implementing the interface in order to minimize boilerplate.

onConferenceFailed

Called when a joining a conference was unsuccessful or when there was an error while in a conference.

The data Map contains an "error" key describing the error and a "url" key with the conference URL.

onConferenceJoined

Called when a conference was joined.

The data Map contains a "url" key with the conference URL.

onConferenceLeft

Called when a conference was left.

The data Map contains a "url" key with the conference URL.

onConferenceWillJoin

Called before a conference is joined.

The data Map contains a "url" key with the conference URL.

onConferenceWillLeave

Called before a conference is left.

The data Map contains a "url" key with the conference URL.

onLoadConfigError

Called when loading the main configuration file from the Jitsi Meet deployment fails.

The data Map contains an "error" key with the error and a "url" key with the conference URL which necessitated the loading of the configuration file.

ProGuard rules

When using the SDK on a project some proguard rules have to be added in order to avoid necessary code being stripped. Add the following to your project's rules file:

# React Native

# Keep our interfaces so they can be used by other ProGuard rules.
# See http://sourceforge.net/p/proguard/bugs/466/
-keep,allowobfuscation @interface com.facebook.proguard.annotations.DoNotStrip

Picture-in-Picture

JitsiMeetView will automatically adjust its UI when presented in a Picture-in-Picture style scenario, in a rectangle too small to accommodate its "full" UI.

Jitsi Meet SDK automatically enables (unless explicitly disabled by a setPictureInPictureEnabled(false) call) Android's native Picture-in-Picture mode iff the platform is supported i.e. Android >= Oreo.
