Android assigns each application a UID (User ID) at install time; unlike PID (Process ID) which is transient and keeps changing all the time, UID stays constant as long as the application is not reinstalled. The UID should be unique to each application, except when the application explicitly requests to share a userid with another application (there are security restrictions around this, the two applications must be signed with the same private key, i.e. comes from the same developer).

These applications claims to show UID of applications:


Try looking at /data/system/packages.xml (you need root to view this file), each installed application should have an entry there. Say, I have Adobe Reader installed in my phone:

<package name="com.adobe.reader" codePath="/mnt/asec/com.adobe.reader-1/pkg.apk" flags="262144" ts="1300539048000" version="37149" userId="10034" installer="com.google.android.feedback">
<sigs count="1">
<cert index="21" key="... very long random string ..." />
<perms />

My phone have assigned userId="10034" to Adobe Reader.

For applications that have requested to share user id with another application, say Handcent:

<package name="com.handcent.nextsms" codePath="/system/app/HandcentSMS.apk" flags="1" ts="1217592000000" version="373" sharedUserId="10064">
<sigs count="1">
<cert index="17" key="... very long random string ..." />

then the attribute you're looking for is sharedUserId="10064"

Thanks! It works! –  azat Apr 19 '11 at 19:55

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.

I try this, but it doesn't works, because such app is not already running –  azat Apr 19 '11 at 13:54
This is for PID, the asker was referring to UID –  Lie Ryan Apr 19 '11 at 17:21
The UID is shown in the ps output as well as the PID. The ps output typically has lines like '12345 app_118...' where 12345 is the PID and app_118 is the UID (corresponding to userId=10118 in /data/system/packages.xml) –  Art Swri Jun 12 '13 at 16:09

In ADB shell (or terminal emulator) use the following command:

cat /proc/<your_process_id_here>/status

and look in the "Name" field. This should be the name of the process. So in your case it would be "cat /proc/10058/status"
