View app's full package name? I am using Android 4.0.3 and I can no longer find package name for some app. If I recall, I used to go to Applications and has been able to see it there. 

So, how can I see full package name of some app? Like, the app's name is "Test" and I need to see its package com.test.mytest.
If you're comfortable using the command line, a solution I like is Android's pm command. It can easily be called using adb like so:

$ adb shell "pm list packages -f test"
package:/system/app/AutomationTest_JBUP.apk=com.sec.android.app.DataCreate
package:/system/app/BluetoothTest.apk=com.sec.android.app.bluetoothtest


Replace test with whatever package you're looking for.

pm has a variety of options that may be useful depending what you want to do:

usage: pm list packages [-f] [-d] [-e] [-s] [-3] [-i] [-u] [FILTER]
pm list packages: prints all packages, optionally only
  those whose package name contains the text in FILTER.  Options:
    -f: see their associated file.
    -d: filter to only show disbled packages.
    -e: filter to only show enabled packages.
    -s: filter to only show system packages.
    -3: filter to only show third party packages.
    -i: see the installer for the packages.
    -u: also include uninstalled packages.
