为什么我无法以编程方式在Android中看到所有正在运行的应用程序? [英] Why i can't see all Running Apps in Android Programmatically?
问题描述
我正在尝试列出所有正在运行的应用程序，但是我不知道为什么我不能这样做.
I'm trying to list all running Apps but i don't know why i can't do it.
当我尝试运行以下命令时，我只返回了我的应用程序.
When i try to run the following command, i just have mine application returned.
List<ActivityManager.RunningAppProcessInfo> listProcesses = manager.getRunningAppProcesses();
许多网站都告诉您使用
List<ActivityManager.RunningTaskInfo> alltasks = am.getRunningTasks(Integer.MAX_VALUE);
而且还刚刚退回了我的申请
But also just returned my application
没有root权限可以使所有任务/进程运行吗?
Is there anything to do without root to get all task/process running ?
推荐答案
如上所述，从Android 5(Lollipop)开始不再支持getRunningTasks和getRunningAppProcesses
As stated, getRunningTasks and getRunningAppProcesses are no longer supported starting with Android 5 (Lollipop)
对于较新的Android版本，您需要要求用户向您授予应用程序使用情况"权限，然后向UsageStatsManager询问在特定时间段内运行的应用程序.
For newer Android versions, you need to ask the user to grant you Apps Usage permission and then ask UsageStatsManager for the apps running in a certain period of time.
