Introduction

This document demonstrates how to support our ota-agent solution under your android system.This demonstration is android 4.3 based. If you encounter problems under your some-verson android system,please mailto me: jin.xin@advantech.com.cn

Architecture

RTENOTITLE

The android ota solution is compose of two parts: the C-lanuage  based Ota-agent and the Java-language based OtaService.

  • Ota-agent achieves communiction with the ota-server, besides, it achieves the package download and unzip. But, the Ota-agent is C-language based and it can't invoke the Java-language based android OTA APIs, so the OtaService comes.
  • OtaService is on the android framework layer, so it can invoke the android OTA APIs directly. The OtaService provides as a socket server. So the Ota-agent can invoke the android OTA APIs through the socket connnect providing by OTaService indirectly.

Android OtaService

we now support four commands, you can  extent your commands:

Android Ota-agent

The Android Ota-agent is same as the wise-pass ota-agent，The difference is that I modify the linux's Makefie to Android's Android.mk.

You can get the binary file for android from here:

https://github.com/ADVANTECH-Corp/wise-paas-ota-agent-android

Or you can rebuild the ota-agent under android system too.
