如何在不使用 PackageManager 的情况下读取 Android Manifest？

我正在开发一个 Android 应用程序，它需要比 PackageManager 中提供的信息更多的信息（例如意图过滤器）。我创建了一个解析器来读取 AndroidManifest 文件，但我找不到任何已安装应用程序的 AndroidManifest.xml 的位置。我使用的代码是：

int flags = PackageManager.GET_ACTIVITIES
                       //| PackageManager.GET_CONFIGURATIONS
                       //| PackageManager.GET_DISABLED_COMPONENTS
                       //| PackageManager.GET_GIDS
                       //| PackageManager.GET_INSTRUMENTATION
                       //| PackageManager.GET_INTENT_FILTERS //Not needed (see BUG: http://code.google.com/p/android/issues/detail?id=3217)
                       | PackageManager.GET_META_DATA
                       | PackageManager.GET_PERMISSIONS
                       | PackageManager.GET_PROVIDERS
                       | PackageManager.GET_RECEIVERS
                       | PackageManager.GET_RESOLVED_FILTER
                       | PackageManager.GET_SERVICES
                       | PackageManager.GET_SHARED_LIBRARY_FILES
                       | PackageManager.GET_SIGNATURES
                       | PackageManager.GET_UNINSTALLED_PACKAGES
                       | PackageManager.GET_URI_PERMISSION_PATTERNS;
final PackageInfo pkg = pm.getPackageInfo(info.packageName, flags);
File manifest = new File(pkg.applicationInfo.publicSourceDir + "/AndroidManifest.xml");
if (manifest.exists()) {
    //Code never reaches this point
}

根据文档， ApplicationInfo.publicSourceDir 是：

此内容公开部分的位置的完整路径包（即主要资源包和清单）。为了非前向锁定应用程序，这与 {@link #sourceDir) 相同。

我做错了什么，或者我该如何做正确的事情？

I am working on an Android application that requires more information than what is available in the PackageManager (such as intent filters). I have created a parser for reading the AndroidManifest file, but I cannot find the location of the AndroidManifest.xml for any installed application. The code I am using is:

int flags = PackageManager.GET_ACTIVITIES
                       //| PackageManager.GET_CONFIGURATIONS
                       //| PackageManager.GET_DISABLED_COMPONENTS
                       //| PackageManager.GET_GIDS
                       //| PackageManager.GET_INSTRUMENTATION
                       //| PackageManager.GET_INTENT_FILTERS //Not needed (see BUG: http://code.google.com/p/android/issues/detail?id=3217)
                       | PackageManager.GET_META_DATA
                       | PackageManager.GET_PERMISSIONS
                       | PackageManager.GET_PROVIDERS
                       | PackageManager.GET_RECEIVERS
                       | PackageManager.GET_RESOLVED_FILTER
                       | PackageManager.GET_SERVICES
                       | PackageManager.GET_SHARED_LIBRARY_FILES
                       | PackageManager.GET_SIGNATURES
                       | PackageManager.GET_UNINSTALLED_PACKAGES
                       | PackageManager.GET_URI_PERMISSION_PATTERNS;
final PackageInfo pkg = pm.getPackageInfo(info.packageName, flags);
File manifest = new File(pkg.applicationInfo.publicSourceDir + "/AndroidManifest.xml");
if (manifest.exists()) {
    //Code never reaches this point
}

According to the documentation, ApplicationInfo.publicSourceDir is:

Full path to the location of the publicly available parts of this
package (i.e. the primary resource package and manifest). For
non-forward-locked apps this will be the same as {@link #sourceDir).

What am I doing wrong, or how can I do this right?

这里是代码：

AssetManager am = yourContext.createPackageContext("packageName", 0).getAssets();

XmlResourceParser xml = am.openXmlResourceParser("AndroidManifest.xml");

但是你需要解析它。

Here the code:

AssetManager am = yourContext.createPackageContext("packageName", 0).getAssets();

XmlResourceParser xml = am.openXmlResourceParser("AndroidManifest.xml");

but then you need to parse it.
