Android SDK Access Example

This topic describes how to use AMQP to connect the Android system to the IoT platform and receive subscribed messages from the platform.

Preparations

  • Install Android Studio. Go to the Android Studio website to download and install a desired version. The following uses Android Studio 4.1.1 running on 64-bit Windows as an example.

  • Install the JDK. You can also use the built-in JDK of the IDE.
    1. Go to the Oracle website to download a desired version. The following uses JDK 8 for Windows x64 as an example.
    2. After the download is complete, run the installation file and install Node.js as prompted.

Development Environment

The development environments used in this example are as follows:

Sample Code

  1. Download the AMQP demo.
  2. Run Android Studio, click Open, and select the sample code downloaded in 1.
