如何获取用户已在Android设备上安装的应用程序的列表? [英] How to get the list of apps that have been installed by a user on an Android device?

问题描述

我目前正在使用以下代码:

I am using the following piece of code at the moment:

List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);

，但它返回由设备制造商和我安装的应用程序.如何限制它，以便仅返回我安装的应用程序?

but it returns Apps that have been installed by the both device manufacturer and me. How to limit it so that only the apps that I installed are returned?

推荐答案

// Flags: See below
int flags = PackageManager.GET_META_DATA | 
            PackageManager.GET_SHARED_LIBRARY_FILES |     
            PackageManager.GET_UNINSTALLED_PACKAGES;

PackageManager pm = getPackageManager();
List<ApplicationInfo> applications = pm.getInstalledApplications(flags);
for (ApplicationInfo appInfo : applications) {
    if ((appInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 1) {
        // System application
    } else {
        // Installed by user
    }
}

标志:

• GET_META_DATA
• GET_SHARED_LIBRARY_FILES
• GET_UNINSTALLED_PACKAGES

• GET_META_DATA
• GET_SHARED_LIBRARY_FILES
