需要一些帮助，通过检索Android设备programmaticaly *的.apk文件名？难道任何机构提供了一些Android的方法这样做，还是Android下运行，即使外壳命令来获取文件的位置，如果我知道只是一部分，从文件名？

Need some help by retrieving *.apk file name from Android device programmaticaly ? Could any body provide some Android methods doing that or even shell commands run under Android to get the file location , if I know just a part from file name ?

另外，如果有一种方法如何找出从市场或市场外下载完成后，*的.apk文件去了？

Also if there is a way how to find out where the *.apk file went after downloading from Market or outside Market ?

感谢你在前进。

推荐答案

List<ApplicationInfo> PackageManager.getInstalledApplications（） 会给你安装的应用程序的列表，ApplicationInfo.sourceDir是路径的.apk文件

List<ApplicationInfo> PackageManager.getInstalledApplications() will give you a list of the installed applications, and ApplicationInfo.sourceDir is the path to the .apk file.

PackageManager pm = getPackageManager();

for (ApplicationInfo app : pm.getInstalledApplications(0)) {
  Log.d("PackageList", "package: " + app.packageName + ", sourceDir: " + app.sourceDir);
}

输出是这样的：

Outputs something like this:

package: com.tmobile.themechooser, sourceDir: /system/app/ThemeChooser.apk
package: com.tmobile.thememanager, sourceDir: /system/app/ThemeManager.apk
package: com.touchtype.swiftkey, sourceDir: /data/app/com.touchtype.swiftkey-1.apk
package: com.twitter.android, sourceDir: /data/app/com.twitter.android-2.apk
package: fm.last.android, sourceDir: /data/app/fm.last.android-1.apk
