编程方式检查OTA的Andr​​oid系统更新 [英] Programatically check for Android OTA system updates

问题描述

如果你去设置 - >关于电话 - >检查更新检查开始，看看是否theres任何系统更新准备好您的手机。

我如何做这个动作编程？此外，我想在这里找到在Android源$ C ​​$ C发生这种情况，所以我可以完全看到它，并更好地理解它。有没有人有什么建议？

解决方案

据我所知，目前还没有已知的广播，意图或API以编程方式做到这一点。

和它依赖于ROM中，和制造商。

索尼例如使用服务，当在WiFi被激活时，在索尼公司的服务器的任何更新和它通知服务检查。

但是，当谈到AOSP源代码，我不认为会发生。

中的系统更新的是包/应用程序/设置/ src目录/ COM /安卓/设置发现/ DeviceInfoSettings.java <最近的点/ P>

Protip ：grep的字符串系统更新的 RES /值目录中和工作backwords，并找出该字符串变量标识符用！

修改

下面是一个例子广播接收器：

 公共类SystemUpdateClass扩展的BroadcastReceiver {
   @覆盖
   公共无效的onReceive（上下文的背景下，意图意图）{
      如果（intent.getAction（）。等于（android.settings.SYSTEM_UPDATE_SETTINGS））{
           Toast.makeText（背景下，
                 是啊！收到系统更新广播，
                 Toast.LENGTH_SHORT）.show（）;
      }
   }
}
 

下面是一个例子code，从一个活动的的onCreate ：

  SystemUpdateClass sysUpdate =新SystemUpdateClass（）;
IntentFilter的过滤器=新的IntentFilter（）;
filter.addAction（android.settings.SYSTEM_UPDATE_SETTINGS）;
registerReceiver（sysUpdate，过滤器）;
 

现在，会发生什么是您的应用程序应该接收广播，除非我弄错了广播是一个系统签名的应用程序......然而，剩下的就是作为一个练习：）

If you go to Settings->About Phone->Check for updates a check is initiated to see if theres any system updates ready for your phone.

How can I do this action programmatically? Further, I am trying to locate where in the Android source code this happens so I can see it fully and understand it better. Does anyone have any suggestions?

解决方案

As far as I know, there is no known broadcast, intent or API to do this programmatically.

And it depends on the ROM, and manufacturer.

Sony for example uses a service which, when the wifi is activated, the service checks on Sony's servers for any updates and informs of it.

But when talking about AOSP source, that I do not think happens.

The nearest point of System update is found in packages/apps/Settings/src/com/android/settings/DeviceInfoSettings.java

Protip: grep the string "System update" within the res/values directory and work backwords and find out where that string variable identifier is used!

Edit:

Here's an example broadcast receiver:

public class SystemUpdateClass extends BroadcastReceiver{
   @Override
   public void onReceive(Context context, Intent intent){
      if (intent.getAction().equals("android.settings.SYSTEM_UPDATE_SETTINGS")){
           Toast.makeText(context, 
                 "Yup! Received a system update broadcast", 
                 Toast.LENGTH_SHORT).show();
      }
   }
}

Here's an example code, from within a activity's onCreate:

SystemUpdateClass sysUpdate = new SystemUpdateClass();
IntentFilter filter = new IntentFilter();
filter.addAction("android.settings.SYSTEM_UPDATE_SETTINGS");
registerReceiver(sysUpdate, filter);

Now, what should happen is your app should receive the broadcast, unless I am mistaken that the broadcast is only for system-signed apps... however the rest is left as an exercise :)
