This document describes how to quickly integrate the Tencent Cloud IM SDK to your projects. To configure and integrate the SDK, follow these steps.

Production Environment Requirements

• JDK 1.6.
• Android 4.1 (SDK API 16) or above.

Integrating the SDK (aar)

You can choose to use Gradle to automatically load aar or manually download aar and import it into your current project.

Method 1: automatic loading (aar)

Because the JCenter service will be deprecated, subsequent IM SDKs will be published to the Maven Central repository. You can configure Gradle to automatically download updates.
Use Android Studio to open your project and modify the app/build.gradle file in three simple steps to integrate the SDK to your project, as shown below:

• Step 1: add SDK dependencies

  Find the build.gradle of the app and add mavenCentral() dependencies to repositories.

  repositories {
       google()
       jcenter()
       // Add the `mavenCentral` repository.
       mavenCentral()
  }

  Add the IM SDK dependencies to dependencies.
  If the IM SDK standard edition is used, add the following dependencies:

  dependencies {
    api 'com.tencent.imsdk:imsdk:version number'
  }

  If the IM SDK lite edition is used, add the following dependencies:

  dependencies {
    api 'com.tencent.imsdk:imsdk-smart:version number'
  }

  Note：

  Replace version number with the actual version number of the SDK. You are advised to use the latest version.
  Take the version number 5.3.425 as an example:

  ```

  dependencies {
  api 'com.tencent.imsdk:imsdk-smart:5.3.425'
  }
  ```

• Step 2: specify the application architecture
  In defaultConfig, specify the CPU architecture used by the app (armeabi-v7a, arm64-v8a, x86, and x86_64 are supported starting from IM SDK v4.3.118).

    defaultConfig {
       ndk {
           abiFilters "arm64-v8a"
       }
   }

• Step 3: sync the SDK
  Click the Sync icon. If the connection to jCenter is normal, the SDK will be automatically downloaded and integrated to your project.
  

Method 2: manual download (aar)

If JCenter cannot be accessed, you can manually download the SDK and integrate it into your project:

• Step 1: download the IM SDK
  Download the latest version of the IM SDK from GitHub.

• Step 2: copy the IM SDK to the project directory
  Copy the downloaded aar file to the /libs directory of the project.
  

• Step 3: specify the architecture used by the app and compile and run the architecture
  In the defaultConfig of app/build.gradle, specify the CPU architecture used by the app (armeabi-v7a, arm64-v8a, x86, and x86_64 are supported starting from IM SDK v4.3.118).

  defaultConfig {
  ndk {
    abiFilters "arm64-v8a"
  }
  }

Integrating the SDK

If you do not want to integrate the aar library, you can integrate the IM SDK by importing the jar and so libraries.

• Step 1: download and decompress the IM SDK
  Download the latest version of the aar file from GitHub and decompress it. The extracted folder contains a jar file and a so subfolder. Rename classes.jar to imsdk.jar.
  

• Step 2: copy the SDK files to the project directory
  Copy the renamed jar file and so files of different architectures to the default loading directories of Android Studio.
  

• Step 3: specify the architecture used by the app and compile and run the architecture
  In the defaultConfig of app/build.gradle, specify the CPU architecture used by the app (armeabi-v7a, arm64-v8a, x86, and x86_64 are supported starting from IM SDK v4.3.118).

    defaultConfig {
       ndk {
           abiFilters "arm64-v8a"
       }
   }

Configuring App Permissions

To configure app permissions in AndroidManifest.xml, the IM SDK requires the following permissions:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

Configuring Obfuscation Rules

In the proguard-rules.pro file, add the IM SDK classes to the "do not obfuscate" list.

-keep class com.tencent.imsdk.** { *; }
