android - 如何获取用户在 Android 设备上安装的应用列表？

Question

目前我正在使用以下代码:

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

但它会返回设备制造商和我安装的应用程序。如何限制它以便只返回我安装的应用程序？

Answer 1

// 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
