android - 如何获取 android 中所有设备管理员( Activity 和非 Activity )的列表？

Question

Google API 允许我们从方法中获取设备中所有 Activity 管理员的列表:getActiveAdmins()。但是，我的要求是我想要设备中所有可能的管理员的列表，无论是否处于 Activity 状态。有什么方法可以做到吗？

谢谢

您可以通过以下代码找到应用程序列表

final Intent deviceAdminIntent = new Intent("android.app.action.DEVICE_ADMIN_ENABLED", null);
final List<ResolveInfo> pkgAppsList = getPackageManager().queryBroadcastReceivers(deviceAdminIntent, 0);
for (ResolveInfo aResolveInfo : pkgAppsList) {
    String pkg = aResolveInfo.activityInfo.applicationInfo.packageName;
        String name = aResolveInfo.activityInfo.applicationInfo.loadLabel(getPackageManager()).toString();

    System.out.println("Package :: " + pkg);
    System.out.println("Name :: " + name);
}

您可以在应用程序的 ResolveInfo 中获取所有必要的数据。您可以查看 ResolveInfo javadoc here .

我写了一个返回 ComponentName 的方法与getActiveAdmins相同

private List<ComponentName> getAllAdmins(Context mContext) {
        List<ComponentName> result = new ArrayList<ComponentName>();

        // Read all receivers who can listen android.app.action.DEVICE_ADMIN_ENABLED 
        // You can add all other action which can be used for DeviceAdminReceiver 
        final Intent deviceAdminIntent = new Intent("android.app.action.DEVICE_ADMIN_ENABLED", null);
        final List<ResolveInfo> pkgAppsList = mContext.getPackageManager().queryBroadcastReceivers(deviceAdminIntent, 0);
        for (ResolveInfo aResolveInfo : pkgAppsList) {
            // Prepare component and add to list

            result.add(new ComponentName(aResolveInfo.activityInfo.applicationInfo.packageName,
                    aResolveInfo.activityInfo.name)); 

            //String pkg = aResolveInfo.activityInfo.applicationInfo.packageName;
            //String name = aResolveInfo.activityInfo.applicationInfo.loadLabel(getPackageManager()).toString();
            //System.out.println("Package :: " + pkg);
            //System.out.println("Name :: " + name);
        }
        return result; 
    }
