1-to-1 Video Chat App on Android Using the Agora 4.x SDK Preview

In this tutorial, we will build a basic video chat app for Android using the Agora Video 4.0 SDK Preview. The prerequisites include Android Studio, basic knowledge of Java and Android SDK, and an Agora.io developer account. We will follow these steps: 1. Get your App ID from the Agora Console. 2. Integrate JCenter into the project level /app/build.gradle file. 3. Set up the Agora App ID in the Android project's Strings.xml file and add necessary permissions within Manifest.xml. 4. Set up views for the UI elements, such as ImageView or Button. 5. Check permissions by requesting users to grant access to camera and audio recording. 6. Initialize the Agora SDK, set up user profile, and configure video quality settings. 7. Connect the video streams by setting up local and remote video containers. 8. Set up the SDK Event Handler to handle various events triggered by the engine. 9. Join and leave channels using the engine's joinChannel() and leaveChannel() methods. 10. Add other functionality, such as toggling microphone and video streams on the local device.
