如何获得所有的应用程序（包括系统应用）的名单？ [英] How to get list of ALL apps (including System Apps)?

问题描述

我做下面让应用程序列表，我只获得已安装的应用程序，但并非所有的应用，包括系统应用。

I am doing the following to get the list of apps and I am only getting apps that were installed but not ALL apps, including system apps.

我曾尝试以下内容：

    packageList1 = getPackageManager().getInstalledPackages(PackageManager.GET_META_DATA);

和这样的：

    packageList1 = getPackageManager().getInstalledPackages(0);

有关这两种情况下，我得到了我已经安装在手机上的应用程序相同的列表。

For both cases, I am getting the same list of apps that I have installed on the phone.

推荐答案

您已经获得所有已安装的应用程序的列表，包括通过调用该系统的应用程序：

You are already getting a list of all installed applications including the system apps by calling this:

List<ApplicationInfo> apps = getPackageManager().getInstalledPackages(0);

那些具有标志：

• ApplicationInfo.FLAG_UPDATED_SYSTEM_APP


• ApplicationInfo.FLAG_SYSTEM

• ApplicationInfo.FLAG_UPDATED_SYSTEM_APP
• ApplicationInfo.FLAG_SYSTEM

是系统的应用程序。您可以检查这样的标志：

are system apps. You can check for the flags like this:

List<ApplicationInfo> apps = getPackageManager().getInstalledApplications(0);
for(ApplicationInfo app : apps) {
    if((app.flags & (ApplicationInfo.FLAG_UPDATED_SYSTEM_APP | ApplicationInfo.FLAG_SYSTEM)) > 0) {
        // It is a system app
    } else {
        // It is installed by the user
    }
}
