PackageManager.movePackage（）在哪里？

Question

检查Android文档，这种方法不存在。但看在应用程序管理器（the built in one）的源代码，它使用：

mPm.movePackage(mAppEntry.info.packageName, mPackageMoveObserver, moveFlags); 

的movePackage()方法，而looking in the source code（2.2 Froyo的，API）这样的方法是存在的，声明为public abstract。我想知道我怎样才能访问这个方法？

Answer 1

movePackage

公共抽象无效movePackage（字符串的packageName， android.content.pm.IPackageMoveObserver观察者， INT标志）

Attempts to move package resources from internal to external media or vice versa. Since this may take a little while, the result will be posted back to the given observer. This call may fail if the calling context lacks the Manifest.permission.MOVE_PACKAGE permission, if the named package cannot be found, or if the named package is a "system package". 

Parameters: 
    packageName - The name of the package to delete 
    observer - An observer callback to get notified when the package move is complete. android.content.pm.IPackageMoveObserver#packageMoved(boolean) will be called when that happens. observer may be null to indicate that no callback is desired. 
    flags - To indicate install location MOVE_INTERNAL or MOVE_EXTERNAL_MEDIA
