Android PackageManager：检查库 APK 是否已安装
PackageManager.getPackageInfo(packageName, flags) 方法可用于检查特定包是否已安装。它要么返回 PackageInfo，要么抛出 PackageManager.NameNotFoundException。
如何检查库 APK 是否已安装？库 APK 的一个示例是 Trichrome 库： https://www.apkmirror.com/apk/google-inc/trichrome-library/trichrome-library-98-0-4758-101-release/trichrome-library-98-0-4758-101-3 -android-apk-download/download/
安装此 APK 后，调用PackageManager.getPackageInfo('com.google.android.trichromelibrary', 0) 抛出 PackageManager.NameNotFoundException。
通过 ADB 查看，我发现安装后，它在 pm list packages 下不可见，但在 pm list templates 下可见，名称为“library:com.google.android.三色图书馆”。
有什么方法可以以编程方式确定该库是否已安装？
The PackageManager.getPackageInfo(packageName, flags) method can be used to check whether a specific package has been installed. It either returns the PackageInfo or throws PackageManager.NameNotFoundException.
How to check if a library APK is installed? An example of the library APK is Trichrome Library: https://www.apkmirror.com/apk/google-inc/trichrome-library/trichrome-library-98-0-4758-101-release/trichrome-library-98-0-4758-101-3-android-apk-download/download/
After installation of this APK, calling PackageManager.getPackageInfo('com.google.android.trichromelibrary', 0) throws PackageManager.NameNotFoundException.
Looking via ADB, I see that once installed, it's not visible under pm list packages but it's visible under pm list libraries with the name "library:com.google.android.trichromelibrary".
Is there any way to determine programmatically whether the library has been installed?

正如您在 链接，
pm list links命令使用PackageManager.getSystemSharedLibraryNames()，该记录已记录此处。如果此方法不起作用，PackageManager 中还有其他方法可以获取有关共享库的信息。正如 @vmayorow 所提到的，这些方法之一是
PackageManager.getSharedLibraries(0)。As you can see in the source code of
pmin this link,pm list librariescommand usesPackageManager.getSystemSharedLibraryNames()which is documented here.If this method is not working, there are also other methods in
PackageManagerto get info about shared libraries. As mentioned by @vmayorow, One of these methods isPackageManager.getSharedLibraries(0).
