This tutorial will demonstrate the steps to add video calling features to your Android app in Javascript. Before getting started, we recommend you to create an account with MirrorFly and download the video call SDKs needed for the setup.
Without any delay, let us get started with the development:
There are two ways to add our video call SDKs into your existing video call app,
Let’s get into the details.
The entire integration process begins with the installation of app's dependencies.
Step 1 : Open your Android IDE.
Step 2 : Create a new project or open an existing one.
Step 3 : Add the below given libraries to your project's app/libs folder.
Step 4 : Now, download the library files from your MirroFly SDK files and add them to your project as shown below.
Step 5 : Add the below given codes to the app/build.gradle file.
plugins {
...
id 'kotlin-android'
id 'kotlin-kapt'
}
android {
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
packagingOptions {
exclude 'META-INF/AL2.0'
exclude 'META-INF/DEPENDENCIES'
exclude 'META-INF/LICENSE'
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/license.txt'
exclude 'META-INF/NOTICE'
exclude 'META-INF/NOTICE.txt'
exclude 'META-INF/notice.txt'
exclude 'META-INF/ASL2.0'
exclude 'META-INF/LGPL2.1'
exclude("META-INF/*.kotlin_module")
}
}Step 6 : Continue adding the following dependencies to the app/build.gradle file.
dependencies {
... // your app dependencies
implementation files('libs/appbase.aar')
implementation files('libs/flycommons.aar')
implementation files('libs/flynetwork.aar')
implementation files('libs/flydatabase.aar')
implementation files('libs/videocompression.aar')
implementation files('libs/xmpp.aar')
implementation files('libs/flywebrtc.aar')
}
Step 7 : Now, the SDKs are required to have the below dependencies,
dependencies {
... // your app dependencies
configurations {
all {
exclude group: 'org.json', module: 'json'
exclude group: 'xpp3', module: 'xpp3'
}
}
//For lifecycle listener
implementation 'android.arch.lifecycle:extensions:1.1.1'
annotationProcessor 'android.arch.lifecycle:compiler:1.1.1'

//room database
implementation 'androidx.room:room-runtime:2.2.5'
kapt 'androidx.room:room-compiler:2.2.5'
implementation "androidx.room:room-ktx:2.2.5"
// Lifecycle
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
kapt 'androidx.lifecycle:lifecycle-compiler:2.2.0'
}
Step 8 : Continue adding the below codes to the gradle.properties file, mainly to avoid importing library conflicts.
android.enableJetifier=true
Step 9 : Now, open the AndroidManifest.xml and add the below permissions to it.
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.DISABLE_KEYGUARD" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
buildTypes {
debug {
buildConfigField 'String', 'SDK_BASE_URL', '"https://api-preprod-sandbox.mirrorfly.com/api/v1/"'
buildConfigField 'String', 'LICENSE', '"xxxxxxxxxxxxxxxxxxxxxxxxx"'
buildConfigField 'String', 'WEB_CHAT_LOGIN', '"https://webchat-preprod-sandbox.mirrorfly.com/"'
buildConfigField "String", "SUPPORT_MAIL", '"contussupport@gmail.com"'
}
}
You require some critical data for the video call SDK to operate properly. Thus, you need a ChatSDK builder class to provide data to call SDKs.
Now, add the below lines in the oncreate() method of your application class,
| Argument | Description | Type |
|---|---|---|
| CALL_UI_ACTIVITY | Class | Activity which needs to be invoked during incoming call. when a incoming call is received Call sdk will start this activity with the call details |
@Override
public void onCreate() {
super.onCreate();
//Initialize call manager
CallManager.init(this);
//set your call activity
CallManager.setCallActivityClass(CALL_UI_ACTIVITY.class);
CallManager.setMissedCallListener((isOneToOneCall, userJid, groupId, callType, userList) -> {
//show missed call notification
});
CallManager.setCallHelper(new CallHelper() {
@NotNull
@Override
public String getDisplayName(@NotNull String jid) {
return ContactManager.getDisplayName(jid);
}
@Override
public String getNotificationContent(@NonNull String callDirection) {
return CallNotificationHelper.getNotificationMessage();
}
@Override
public boolean isDeletedUser(@NonNull String jid) {
return ContactManager.getProfileDetails(jid).getContactType() == ContactType.DELETED_CONTACT;
}
@Override
public void sendCallMessage(@NotNull GroupCallDetails details, @NotNull List users, @NotNull List invitedUsers) {
CallMessenger.sendCallMessage(details, users, invitedUsers);
}
});
}
In your manifest, you need to define the Call UI Activity as given below,
<activity
android:name="YOUR_CALL_ACTIVITY"
android:configChanges="screenSize|smallestScreenSize|screenLayout|orientation"
android:excludeFromRecents="true"
android:launchMode="singleTask"
android:resizeableActivity="false"
android:screenOrientation="portrait"
android:supportsPictureInPicture="true"
android:showOnLockScreen="true"
android:turnScreenOn="true"
android:taskAffinity="call.video"
tools:targetApi="o_mr1" />
Now, to configure the call activity you can call the below method on your call activity onCreate(),
CallManager.configureCallActivity(ACTIVITY);
If you wish to notify the call SDK to remove the ongoing call notification, call the below method on onStart() from your activity.
CallManager.bindCallService();
To notify the call SDK to show the ongoing call notification, must call the below onStop() method from your call activity.
CallManager.bindCallService();
To make or receive calls, the SDKs need permissions for both audio and video as given below,
You require a below permission to make a voice call
Manifest.permission.RECORD_AUDIO
Manifest.permission.READ_PHONE_STATE
To check for the audio permission, you can use this below method,
CallManager.isAudioCallPermissionsGranted();
The same way to make a video call you require the below permission,
Manifest.permission.RECORD_AUDIO
Manifest.permission.CAMERA
Manifest.permission.READ_PHONE_STATE
To check for a video call permission you can use the below mentioned method,
CallManager.isVideoCallPermissionsGranted();
| Arguments | Type | Description |
|---|---|---|
| TO_JID | String | jid of the call receiver |
| CALLBACK | CallActionListener | callback to observe the action status |
As soon as the permissions are checked, you can use the following codes to make a one-to-one video call to get connected with another user.
CallManager.makeVideoCall("TO_JID", (isSuccess, message) -> {
});
To make a Group video call, you can use the following codes to add group video call functionality,
CallManager.makeGroupVideoCall(JID_LIST, GROUP_ID, (isSuccess, message) -> {
});
Once, the call is connected you get access to add users to the ongoing call using the below codes:
| Arguments | Type | Description |
|---|---|---|
| JID_LIST | List |
jid list of the callee's |
CallManager.inviteUsersToOngoingCall(JID_LIST);
If your android device’s version is greater than or equal to Android 10 (API level 29), your call SDK will notify you about every incoming call you receive. Otherwise, the set activity will get started during the SDK initialization using the CallManager.setCallActivityClass() method.
Whenever a user (callee) accepts an incoming call, the below given two primary actions are performed :
Hence, the below codes will be used to achieve the same:
| Arguments | Type | Description |
|---|---|---|
| CALLBACK | CallActionListener |
callback to observe the action status |
CallManager.answerCall((isSuccess, message) -> {
});
Whenever the callee declines a call without answering it, the below activities will take place :
You can use the below codes to establish this process,
CallManager.declineCall();
To disconnect an ongoing call, the user needs to follow the below codes,
CallManager.disconnectCall();
