To integrate Android SDK with your unity project, please follow the below mentioned steps:

• In Unity project folder, create Assets/Plugins/Android/ folder
• Set android related configurations in Unity, from File -> Build Profile (Android platform) and select Player settings.
• From player settings do following things
  • In Other setting, Minimum API Level 24
  • In Publishing Settings, Check:
    • Custom Main Gradle Template
    • Custom Base Gradle Template
    • Custom Gradle Properties Template
    • Custom Gradle Settings Template
    • Custom Proguard File
• In mainTemplate.gradle, add the marked lines

apply plugin: 'com.android.library'
apply from: '../shared/keepUnitySymbols.gradle'
apply from: '../shared/common.gradle'

• Add the script in unity project to start the REVEChat SDK activity

using System.Collections;

    void Start()
    {

    }

    IEnumerator LaunchReveChatWithDelay()
    {
        yield return null;
