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 problem under your some-versio android system,please mailto me: jin.xin@advantech.com.cn
Architecture
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.
switch(Advaction.getAdvaction(asplit[0])){
case systembackup:
Slog.i(TAG, "switch systembackup");
RecoverySystem.rebootSystemBackup(mContext);
break;
case wipedata:
Slog.i(TAG, "switch wipedata");

case wipecache:
Slog.i(TAG, "swtich wipecache");
RecoverySystem.rebootWipeCache(mContext);
break;
case install:
Slog.i(TAG, "switch install");
String file = asplit[1].trim();
Slog.i(TAG, "install file: " + file);
File recoveryFile = new File(file);
if(!recoveryFile.exists()){
Slog.i(TAG, "install, file not exist");
return;
}
// first verify package
