一个应用程序可以判断是手机和权限它们对其他应用程序？ [英] Can an app determine the other apps that are on the phone and what permissions they have?

问题描述

我想知道如果一个应用程序可以访问，显示的电话，他们有（即存取您的位置，联系方式等），哪些权限的其他应用程序的信息。我可以创建与显示其他应用程序和权限的功能的应用程序？我知道，用户可以查看通过设置这个信息，但我想知道，如果它可以通过一个应用程序来组织和显示。

I'm wondering if an app has access to the info that shows the other apps on the phone and what permissions they have (i.e. access to your location, contacts, etc). Could I create an app with a feature that displays other apps and their permissions? I know the user can view this info via settings, but I'm wondering if it can be organized and displayed by an app.

推荐答案

是的。使用 软件包管理系统 。呼叫<一个href=\"http://developer.android.com/reference/android/content/pm/PackageManager.html#getInstalledPackages(int)\"相对=nofollow> GetInstalledPackages 列出已安装的软件包，然后检查<一个href=\"http://developer.android.com/reference/android/content/pm/PackageInfo.html#requestedPermissions\"相对=nofollow> requestedPermissions 现场看到每个包的权限。

Yes. Use the PackageManager. Call GetInstalledPackages to list the installed packages, and then check the requestedPermissions field to see the permissions for each package.

请注意：下面的方法假设这个指活动

Note: the method below assumes this refers to an Activity.

private void getAppPermissions() {

    List<PackageInfo> apps = this.getPackageManager().getInstalledPackages(PackageManager.GET_PERMISSIONS);

    for (PackageInfo app : apps) {
        String appInfo = app.packageName + ": ";
        String[] permissions = app.requestedPermissions;
        if (null == permissions) {
            appInfo += "no permissions requested\n";
        } else {
            for (String permission : app.requestedPermissions) {
                appInfo += "\n    " + permission;                   
            }
        }
        Log.v("App Permissions", appInfo);
    }
}
