Top 5 Tips for Video Chat On Android

Without a doubt, Android apps keep getting better as technology advances. Although some Android apps may have recently changed their tune, the Android video chat function has remained the most common. We’ll learn how to create video chat applications for Android with ZEGOCLOUD; win this post.

Tip 1. What is Video Chat?

Video chat, or video chatting, is a communication technique whereby real-time video and audio signals are continuously transmitted between the connected users and the service server.

It has quickly become the most convenient way of passing information face-to-face. With video chat apps, freedom of expression is assured.

Tip 2. Must-have Features of Video Chat on Android

We have so many Android video chat apps existing today. From Facebook Messenger to Zoom, and many more. If you take the time to explore most of them, you’ll notice that they all have some features in common.

Below are the must-have features of video chat on Android:

1. Registration

Registration interface is a common feature in almost every video chat application. It helps with user management and provides more straightforward identification of users on the platform.

2. Group calls

Group call is an effective way of distributing some chunks of information to a broader audience. Many video chat apps allow more than two people to chat conveniently in a group.

3. Screen sharing

There’s no better way to share information displayed on the screen than using the screen-sharing feature many video chat providers offer. All you have to do is just tap on the “share screen” button or its equivalent in the video chat you’re using, and boom, you’re good to go.

4. End-to-end encryption

Privacy is essential in almost every communication app, not only video chat. End-to-end encryption protocol ensures that information isn’t leaked to a third party apart from the connected individuals.

5. Text messaging

I know text messaging can be very boring for some people, but it may come in handy when users on the chat can’t hear each other, want to send some additional information, or simply cannot talk at the moment.

6. Meeting recording

Recording a video chat can be a great way of creating moments that can be used for reference purposes or further distribution.

7. Push notifications

The push notifications feature in the video chat app ensures that your users never miss a moment. They update your users about new messages in the chat and missed calls and keep them informed about new updates.

8. Contact list

This works like the regular contact on your phone. It keeps track of the people you’re connected with.

The first part of creating our Android video chat app is developing the project in Android Studio.

You can follow the steps below to create a project in Android Studio:

  1. Open Android Studio and select FileNewProject.

Import the SDK

Integrating ZEGOCLOUD’s Video Call SDK into your project is very easy.

Just follow the steps below to fire it up in your project:

  1. Download the latest version of the Video Call SDK.
  2. Extract the files from the SDK packages into your project directory, for example, app/libs.
add sdk video chat on android
  1. Add SDK import statements. Open the file app/build.gradle and add the following contents:

a. Add the ndk node inside the defaultConfig node to specify the supported ABIs.

ndk {
    abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64'

b. Add the sourceSets node inside the android node to specify the directory containing the SDK files.

    sourceSets {
        main {
            jniLibs.srcDirs = ['libs']

c. Add the following code in the dependencies node:

  dependencies {
      implementation fileTree(dir: 'libs', include: ['*.jar'])

Add permissions

We need some permissions in order to make use of some systems resources.

Open the File app/src/main/AndroidManifest.xml, and add the following code for the permissions:

<!-- Permissions required by the SDK  -->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

<!-- Permissions required by the App -->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

    android:required="true" />

<uses-feature android:name="" />
<uses-feature android:name="" />

Prevent class name obfuscation

To prevent the ZEGO SDK public class names from being obfuscated, you can add the following code in the File

-keep class **.zego.**{*;}

Implement Video Call

Create a new activity.

1 Create a new empty activity and name it CallActivity.

  1. modify its layout file, activity_call.xml in the res/layout directory.
<?xml version="1.0" encoding="utf-8"?>
    <androidx.constraintlayout.widget.ConstraintLayout xmlns:android=""

call activity mod
  1. Modify ZegoUIKitPrebuiltCallFragment to display the Call Kit UI on the screen.
public void addFragment() {
    long appID = ;
    String appSign = ;
    String callID = "callID111";
    String userID = Build.MANUFACTURER + "_" + generateUserID();
    String userName = userID + "_Name";
    ZegoUIKitPrebuiltCallConfig config = ZegoUIKitPrebuiltCallConfig.oneOnOneVideoCall();
    ZegoUIKitPrebuiltCallFragment fragment = ZegoUIKitPrebuiltCallFragment.newInstance(appID,      appSign, userID, userName, callID, config);
    getSupportFragmentManager().beginTransaction().replace(, fragment).commitNow();

  1. Add a “Call Button” to MainActivity to initiate video calls.


   <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android=""

        android:text="start video call" />

   public class MainActivity extends AppCompatActivity {

        protected void onCreate(Bundle savedInstanceState) {

            findViewById( -> {
                Intent intent = new Intent(MainActivity.this, CallActivity.class);

Run a demo.

You can test the app on an Android device or Android emulator with audio and video support.
