阿贾伊，

要得到你将要使用的<一个安装日期href="http://developer.android.com/reference/android/content/pm/PackageManager.html"><$c$c>PackageManager类。更具体地，<一href="http://developer.android.com/reference/android/content/pm/PackageManager.html#getPackageInfo%28java.lang.String,%20int%29"><$c$c>getPackageInfo()方法。这会回报给你一个<一个href="http://developer.android.com/reference/android/content/pm/PackageInfo.html"><$c$c>PackageInfo对象，它包含<一个href="http://developer.android.com/reference/android/content/pm/PackageInfo.html#firstInstallTime"><$c$c>firstInstallTime值。

To get the installation date you will want to use the PackageManager class. More specifically the getPackageInfo() method. This will return to you a PackageInfo object which contains firstInstallTime value.

还有目前不存在一个公共API来获取应用程序的大小 PackageManager.getpackageSizeInfo（）是从SDK 0.9的API拆下来SDK 1.0。请参阅<一href="http://groups.google.com/group/android-developers/browse_thread/thread/df94daae34336aad/f96a8425549c6637">HERE

There does not currently exist a public API to get an application's size as PackageManager.getpackageSizeInfo() was removed from the API from SDK 0.9 to SDK 1.0. See HERE
