IoT Platform:Environment requirements and configuration

Configure Link SDK for Android

1. Add the address of the Alibaba Cloud repository to the build.gradle or settings.gradle file in the root directory of the Android project.

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

2. Add dependencies to the ./build.gradle file of the related module, such as app, and download Link SDK for Android.

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

AndroidX features

If you create a project that supports AndroidX features, the keyword androidx is included in the build.gradle file of the related module. In this case, specify the following code in the gradle.properties file:

android.enableJetifier=true
