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 }
}

Also, enable 32bit mode for react-native, since react-native only supports 32bit apps. (If you have a 64bit device, it will not run unless this setting it set)

android {
    ...
    defaultConfig {
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }
    ...

Build and use your own SDK artifacts/binaries

Show building instructions

Start by making sure that your development environment is set up correctly.

A note on dependencies: Apart from the SDK, Jitsi also publishes a binary Maven artifact for some of the SDK dependencies (that are not otherwise publicly available) to the Jitsi Maven repository. When you're planning to use a SDK that is built from source, you'll likely use a version of the source code that is newer (or at least different) than the version of the source that was used to create the binary SDK artifact. As a consequence, the dependencies that your project will need, might also be different from those that are published in the Jitsi Maven repository. This might lead to build problems, caused by dependencies that are unavailable.

If you want to use a SDK that is built from source, you will likely benefit from composing a local Maven repository that contains these dependencies. The text below describes how you create a repository that includes both the SDK as well as these dependencies. For illustration purposes, we'll define the location of this local Maven repository as /tmp/repo

In source code form, the Android SDK dependencies are locked/pinned by package.json and package-lock.json of the Jitsi Meet project. To obtain the data, execute NPM in the parent directory:

$ (cd ..; npm install)

This will pull in the dependencies in either binary format, or in source code format, somewhere under /node_modules/

At the time of writing, there are two packages pulled in in binary format.

To copy React Native to your local Maven repository, you can simply copy part of the directory structure that was pulled in by NPM:

$ cp -r ../node_modules/react-native/android/com /tmp/repo/

In the same way, copy the JavaScriptCore dependency:

$ cp -r ../node_modules/jsc-android/dist/org /tmp/repo/

Alternatively, you can use the scripts located in the android/scripts directory to publish these dependencies to your Maven repo.

Third-party React Native modules, which Jitsi Meet SDK for Android depends on, are download by NPM in source code form. These need to be assembled into Maven artifacts, and then published to your local Maven repository. The SDK project facilitates this.

To prepare, Configure the Maven repositories in which you are going to publish the SDK artifacts/binaries. In android/sdk/build.gradle as well as in android/build.gradle modify the lines that contain:

"file:${rootProject.projectDir}/../../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:

"file:/tmp/repo"

Make sure to do this in both files! Each file should require one line to be changed.

To prevent artifacts from previous builds affecting you're outcome, it's good to start with cleaning your work directories:

$ ./gradlew clean

To create the release assembly for any specific third-party React Native module that you need, you can execture the following commands, replace the module name in the examples below.

$ ./gradlew :react-native-webrtc:assembleRelease
$ ./gradlew :react-native-webrtc:publish

You build and publish the SDK itself in the same way:

$ ./gradlew :sdk:assembleRelease
$ ./gradlew :sdk:publish

Alternatively, you can assemble and publish all subprojects, which include the react-native modules, but also the SDK itself, with a single command:

$ ./gradlew clean assembleRelease publish

You're now ready to use the artifacts. In your project, add the Maven repository that you used above (/tmp/repo) into your top-level build.gradle file:

allprojects {
    repositories {
        maven { url "file:/tmp/repo" }
        google()
        jcenter()
    }
}

You can use your local repository to replace the Jitsi repository (maven { url "https://github.com/jitsi/jitsi-maven-repository/raw/master/releases" }) when you published all subprojects. If you didn't do that, you'll have to add both repositories. Make sure your local repository is listed first!

Then, define the dependency org.jitsi.react:jitsi-meet-sdk into the build.gradle file of your module:

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

Note that there should not be a need to explicitly add the other dependencies, 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.

Note that this should only be needed when JitsiMeetActivity cannot be used for some reason. Extending JitsiMeetView requires manual wiring of the view to the activity, using a lot of boilerplate code. Using the Activity instead of the View is strongly recommended.

Show example

package org.jitsi.example;

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

import org.jitsi.meet.sdk.JitsiMeetView;
import org.jitsi.meet.sdk.ReactActivityLifecycleCallbacks;

// Example
//
public class MainActivity extends AppCompatActivity {
    private JitsiMeetView view;

    @Override
    protected void onActivityResult(
            int requestCode,
            int resultCode,
            Intent data) {
        ReactActivityLifecycleCallbacks.onActivityResult(
                this, requestCode, resultCode, data);
    }

    @Override
    public void onBackPressed() {
        ReactActivityLifecycleCallbacks.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;

        ReactActivityLifecycleCallbacks.onHostDestroy(this);
    }

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

    @Override
    public void onRequestPermissionsResult(
            final int requestCode,
            final String[] permissions,
            final int[] grantResults) {
        ReactActivityLifecycleCallbacks.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }

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

        ReactActivityLifecycleCallbacks.onHostResume(this);
    }

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

        ReactActivityLifecycleCallbacks.onHostPause(this);
    }
}

Starting with SDK version 1.22, a Glide module must be provided by the host app. This makes it possible to use the Glide image processing library from both the SDK and the host app itself.

You can use the code in JitsiGlideModule.java and adjust the package name. When building, add the following code in your app/build.gradle file, adjusting the Glide version to match the one in https://github.com/jitsi/jitsi-meet/blob/master/android/build.gradle

// Glide
implementation("com.github.bumptech.glide:glide:${glideVersion}") {
    exclude group: "com.android.support", module: "glide"
}
implementation("com.github.bumptech.glide:annotations:${glideVersion}") {
    exclude group: "com.android.support", module: "annotations"
}

JitsiMeetActivity

This class encapsulates a high level API in the form of an Android Activity which displays a single JitsiMeetView.

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.

ReactActivityLifecycleCallbacks

This class handles the interaction between JitsiMeetView and its enclosing Activity. Generally this shouldn't be consumed by users, because they'd be using JitsiMeetActivity instead, which is already completely integrated.

All its methods are static.

onActivityResult(...)

Helper method to handle results of auxiliary activities launched by the SDK. Should be called from the activity method of the same name.

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.

onHostDestroy(...)

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

onHostResume(...)

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

onHostStop(...)

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

onNewIntent(...)

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.

onRequestPermissionsResult(...)

Helper method to handle permission requests inside the SDK. It should be called from the activity method of the same name.

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 is also provided. 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: https://github.com/jitsi/jitsi-meet/blob/master/android/app/proguard-rules.pro

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.

Dropbox integration

To setup the Dropbox integration, follow these steps:

1. Add the following to the app's AndroidManifest.xml and change <APP_KEY> to your Dropbox app key:

<activity
    android:configChanges="keyboard|orientation"
    android:launchMode="singleTask"
    android:name="com.dropbox.core.android.AuthActivity">
  <intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.BROWSABLE" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:scheme="db-<APP_KEY>" />
  </intent-filter>
</activity>

2. Add the following to the app's strings.xml and change <APP_KEY> to your Dropbox app key:

<string name="dropbox_app_key"><APP_KEY></string>
