拿到包的版本被替换Android中 [英] Get the version of the package been replaced in Android

问题描述

我有一个广播接收器注册时得到通知发送PACKAGE_REPLACED意图。
在onReceiver我需要的软件包的版本的基础上执行某些操作被取代。
是否有一种方式来获得这些信息？我想：

I have a Broadcast receiver registered to be notified when PACKAGE_REPLACED intent is sent. In the onReceiver I need to perform some operations on the basis of the version of the package been replaced. Is there a way to get that information? I tried:

Uri data = intent.getData();
final String intentPackageName = data.getEncodedSchemeSpecificPart();
pi = context.getPackageManager().getPackageInfo(intentPackageName , PackageManager.GET_META_DATA);
versionCode = pi.versionCode;
versionName = pi.versionName;
packageName = pi.packageName;

因为版本已经更换，我所得到的是新的，而不是旧的它不工作。

It does not work because the version is already replaced and what I get is the new and not the old one.

推荐答案

在姜饼版本的源刚才检查。我想这是不可能的检查。应用程序的previous版本没有被存储。我不知道为什么。您可以创建一个功能请求，谷歌添加此功能。

Just checked in the sources of Gingerbread version. I guess that this is impossible to check. Previous version of the application is not stored. I do not know why. You can create a feature request to Google to add this feature.
