推荐答案
- PackageManager.getInstalledApplications（INT标志）将为您提供有关AndroidManifest的
应用程序标签的信息，只是它。忘掉活动，接收器，服务也不管了。 - PackageManager.getInstalledPackages（INT标志），在另一方面，将为您提供有关信息的所有 AndroidManifest的元素，如申报的活动，服务，接收器，荟萃数据
- PackageManager.getInstalledApplications(int flags) will provide you information regarding the AndroidManifest's
Applicationtag, and just about it. Forget about activities, receivers, services and go on. - PackageManager.getInstalledPackages(int flags), on the other hand, will provide you information regarding all AndroidManifest's elements, such as declared activities, services, receivers, meta-data
这两种方法都将提供有关信息的任何应用程序，无论他们或他们没有宣布一些活动的 android.intent.category.LAUNCHER 意图类别。
Both methods will provide info regarding whatever application, regardless they have or they have not declared an android.intent.category.LAUNCHER intent category in some activity.
在此外，这两种方法将检索一个PackageInfo / ApplicationInfo每APK，或者是更具体的，用于包名称
In addition, both methods will retrieve one PackageInfo/ApplicationInfo per APK, or being more specific, for package name.
