Hello you can use the PackageManager clas for this:

    List<PackageInfo> pInfos = getPackageManager().getInstalledPackages(PackageManager.GET_ACTIVITIES);
for (PackageInfo pInfo : pInfos) {
  ActivityInfo[] aInfos = pInfo.activities;
  if (aInfos != null) {
    for (ActivityInfo activityInfo : aInfos) {
      Log.i("ACT", activityInfo.name);
      // do whatever else you like... 
    }
  }
}

I guess you need to look at the ActivityManager ( http://developer.android.com/reference/android/app/ActivityManager.html ). This will help you to find the running process. Perhaps this helps:

boolean ProcessRunning(String name) {
        ActivityManager manager = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
        List<RunningProcess> processes = manager.getRunningAppProcesses();
        for (RunningProcess process : processes) {
            if (name.equals(process.name)) {
                return true;
            }
        }
        return false;
}

I didn't test this, but this link could also be helpful: Automate closing of applications in Android

您只能看到已启动的应用程序列表，并且不能通过自己的应用程序杀死其他应用程序，因为它是由OS处理的。
