Environment requirements and configurations

Configure the SDK

1. Add the Alibaba Cloud repository address to the root configuration file (build.gradle or settings.gradle) of your Android project.

   maven {
       url "https://maven.aliyun.com/nexus/content/repositories/releases/"
   }         

2. In the ./build.gradle file of the relevant module, such as the App module, add the SDK dependency.

   Note

   To upgrade from an older version of the SDK, you must first delete the following coordinates from the .gradle file:

   • com.aliyun.alink.linksdk:iot-linkkit

   • com.aliyun.alink.linksdk:iot-device-manager

   • com.aliyun.alink.linksdk:public-channel-core

   implementation ('com.aliyun.alink.linksdk:lp-iot-linkkit:1.7.3.8') 

AndroidX feature support

For projects that support AndroidX, add the following configuration to the gradle.properties file. A project supports AndroidX if the module's build.gradle file contains the androidx keyword.

android.enableJetifier=true
