process id of a process

[Ubuntu guy]

Hi,

is there anyway to find out the process id by the process name? In
my case the process is executed by dalvik vm. I was hoping to find it
in android.os.process but no luck.

Process names are not unique.

aren't they unique? I see them as com.android.phone all the time...

That is just a string.  There is no guarantee that multiple processes don't have the same name.

Ok, in my case the name is going to be unique.
So could you share the java API to get the pid?

[Dianne Hackborn]

There isn't one.  Trying to find a process by name is just plain wrong.  It is not guaranteed to work, and is not secure, and any process can change its name so you can't know it is going to be unique.

This is just not the right way to do whatever you are trying to accomplish.

In the interests of protecting your (potential) users from security
issues, what are you trying
to do *exactly*?

Well, this is not targetted for users. This was just for debugging
purpose where i'm
interested in knowing the details of other process from a different
process and for that
i need to know the other process's pid.

From within an activity you can do:
int myPid = android.os.Process.myPid();
to get the pid for your app.

Or, you could do, with a bit of hacking:
//get all process-ids
String command = "ls /proc/";

//get the name of a id
String command = "cat /proc/<pid>/stat";
(will return a string, separated with spaces, where the second part is
the name of the process)

execute the commands with:

Process p = Runtime.getRuntime().exec(command);
BufferedReader in = new BufferedReader(new
InputStreamReader(p.getInputStream()));
String line = null;

while ((line = in.readLine()) != null)
{
//do something with the text in line..
}
