How to check current running applications in Android?
提问by UMAR
I want to check current running applications in android programmatically, similar to how it shows 6 applications if we press and hold the HOMEbutton.
我想以编程方式检查 android 中当前正在运行的应用程序，类似于如果我们按住HOME按钮它显示 6 个应用程序的方式。
I'm mostly interested in the application names.
我最感兴趣的是应用程序名称。

You can get current name package using
您可以使用获取当前名称包
ActivityManager am = (ActivityManager) mContext
.getSystemService(Activity.ACTIVITY_SERVICE);
String packageName = am.getRunningTasks(1).get(0).topActivity
.getPackageName();
You can use this package name to get current active application
您可以使用此包名称来获取当前活动的应用程序

You can check the processName of each element in the list to see if it's the process you're looking for. You can use this code
您可以检查列表中每个元素的 processName 以查看它是否是您要查找的进程。您可以使用此代码
boolean isNamedProcessRunning(String processName){
if (processName == null)
return false;
ActivityManager manager =
(ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
List<RunningAppProcessInfo> processes = manager.getRunningAppProcesses();
for (RunningAppProcessInfo process : processes)
{
if (processName.equals(process.processName))
{
return true;
}
}
return false;
}

A long press of the HOME key brings up a list of recent (not necessarily running) tasks.
长按 HOME 键会显示最近（不一定正在运行）任务的列表。
ActivityManagerhas what you need. Look at getRunningAppProcessesor getRunningTasks.
ActivityManager有你需要的东西。看看getRunningAppProcesses或getRunningTasks。
You can view this information (and much more) by running dumpsys activityvia 'adb shell'.
您可以dumpsys activity通过“adb shell”运行来查看此信息（以及更多信息）。
