Android - How to get the processName or packageName by using PID?
Solution 1
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;
}

This code is a simplified version of Yaqub's code. I use this as a static method in a Util
class:
public static String getAppNameByPID(Context context, int pid){
ActivityManager manager
= (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
for(RunningAppProcessInfo processInfo : manager.getRunningAppProcesses()){
if(processInfo.pid == pid){
return processInfo.processName;
}
}
return "";
}

Kill other processes is generally bad idea..
Look at this Question Android process killer and android task kill..
And also this blog Android: Killing a running process with processid(pid) and package name
And for your question How to get Process Name from pid then
Something like,
Install a terminal emulator, launch it and run:
ps | grep 10058
ps lists the processes and grep filters for the ID you want.
But this only works if the application is running when you run the command.

MY QUESTION: What could I use to retrieve the
processName
orpackageName
of a certain process given itsPID
?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.
here's the image of my task manager:

Loren over 12 yearsThanks for the code. I'm just trying to figure it out first since I'm not that well-versed in Android and it's been a long time since I programmed anything. :)

Loren over 12 yearsYup, I've read that several times. However, it's a project in our class so I have no choice but to comply with the requirements. Thanks for helping.

Loren over 12 yearsIt completely works now with the rest of my code. Thank you so much. :D

Mike Venzke over 9 yearsIf your process is a remote service, this won't work. You'll want to do the same thing, but call am.getRunningServices(), and use an ActivityManager.RunningServiceInfo object. For me, info.process then has: com.[package name]:[process name]

Naveed almost 9 yearsSorry I din't get your point The pid that we are passing to this function we are already getting from RunningAppProcessInfo object so instead of passing to this function and again get list of all running apps, we can directly call property from RunningAppProcessInfo object i,e processInfo.processName

Amaksoft over 5 yearsDoesn't work on API above 23 as
getRunningAppProcesses()
only returns your application's processes. Apparently there is no correct way to obtain other application package by its PID. See Dianne Hackborn answer to similar question. groups.google.com/d/msg/android-platform/pmL5wl2w7PU/…
