Android的 - 如何让processName或通过的packageName采用PID？ [英] Android - How to get the processName or packageName by using PID?

问题描述

我的问题：我能使用它来检索的 processName 或的packageName 给予一定的过程的 PID ？

MY QUESTION: What could I use to retrieve the processName or packageName of a certain process given its PID?

由于我的任务管理器，我想使用PID同时利用killBackgroundProcesses code杀掉的进程。问题是我需要的packageName / processName做到这一点，那将是这样一个麻烦的用户，如果我问他们在processName输入，而不是直接键入其PID。

Since in my task manager I wanted to use the PID while utilizing the killBackgroundProcesses code to kill the processes. Problem is I need the packageName/processName to do that and it would be such a hassle to the user if I asked them to type in the processName rather than just typing its PID.

推荐答案

您好：您可以使用此code，它为我的Andr​​oid 2.3.3：

Hello you can use this code, it works for me in Android 2.3.3:

private String getAppName(int pID)
{
    String processName = "";
    ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);
    List l = am.getRunningAppProcesses();
    Iterator i = l.iterator();
    PackageManager pm = this.getPackageManager();
    while(i.hasNext()) 
    {
          ActivityManager.RunningAppProcessInfo info = (ActivityManager.RunningAppProcessInfo)(i.next());
          try 
          { 
              if(info.pid == pID)
              {
                  CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA));
                  //Log.d("Process", "Id: "+ info.pid +" ProcessName: "+ info.processName +"  Label: "+c.toString());
                  //processName = c.toString();
                  processName = info.processName;
              }
          }
          catch(Exception e) 
          {
                //Log.d("Process", "Error>> :"+ e.toString());
          }
   }
    return processName;
}
