Build An Android Video Call App In 10 Minutes

ZEGOCLOUD has launched a new UIKits SDK, which can complete the development of the Video Call App in 10 minutes. This tool is extremely useful in building an Android video call.

Learn about official website documentation, ZEGOCLOUD video calling API support 1 on 1 calls, and group calls.

This article will show you how to use the UIKits SDK to quickly implement Android Video Call functionality. We will implement the following functions:

1v1 video call
Camera switching
Microphone, speaker management

Introduction to UIKits SDK

UIKits SDK is a brand-new pre-built UIKits and UI Components by ZEGOCLOUD. Through it, We can complete the development of video calls, live streaming, video conference, and other scenarios within 10 minutes.

As shown in the figure, UIKits SDK is responsible for processing audio and video calls and the logic related to text chat. Include:

UI and interaction of the calling module
call status management
Audio and video data transmission

You only need to implement business-related logic. For example:

User login registration
Friends List Management
Call billing recharge

Preparation

A ZEGOCLOUD developer account–Sign up
Android Studio 2020.3.1 or later
Devices with Android 5.0 or later
Basic understanding of Android development

Call Kit SDK integration

Add the `jitpack` configuration.

If your gradle version is later than 6.8, modify your settings.gradle File like this:

dependencyResolutionManagement {
   repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
   repositories {
      maven { url 'https://www.jitpack.io' } // <- Add this line.
   }
}

If not, modify your project-level build.gradle file instead:

allprojects {
    repositories {
        maven { url "https://jitpack.io" }  // <- Add this line.
    }
}

Add ZEGOCLOUD Call Kit.

Modify your app-level build.gradle file:

dependencies {
    ...
    implementation 'com.github.ZEGOCLOUD:zego_uikit_prebuilt_call_android:latest.release'    // add this line in your module-level build.gradle file's dependencies, usually named [app].
}

Implement Video Call

Create a new Activity

1 Create a new empty activity and name it CallActivity.

2 modify it’s layout file ‘activity_call.xml’ in res/layout directory.

<?xml version="1.0" encoding="utf-8"?>
    <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/fragment_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

</androidx.constraintlayout.widget.ConstraintLayout>

3 modify CallActivity to show Call Kit UI
When starting a video call, ZegoUIKitPrebuiltCallFragment needs to be displayed 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(R.id.fragment_container, fragment).commitNow();
}

modify MainActivity to add a Call Button to start video call.

activity_main.xml:

   <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="start video call" />
    </RelativeLayout>

MainActivity.java:

   public class MainActivity extends AppCompatActivity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            findViewById(R.id.button).setOnClickListener(v -> {
                Intent intent = new Intent(MainActivity.this, CallActivity.class);
                startActivity(intent);
            });
        }
    }
