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.

  • It's called application ID: Every Android app has a unique application ID that looks like a Java package name, such as com.example.myapp. This ID uniquely identifies your app on the device and in Google Play Store. Your application ID is defined by the android.defaultConfig.applicationId property in your module's build.gradle.kts file. The naming rules are: It must have at least two segments (one or more dots), each must start with a letter, all characters must be alphanumeric or underscore [a-zA-Z0-9_].

Edit: I like ofir_aghai's answer better, although my answer may still be helpful for apps that aren't on the Google Play Store.

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.

  • This works perfect. As a generic solution, this seems to be the correct answer for the question. Also we can use grep if we know some part of the package name. Commented Jul 21, 2014 at 9:17

    @gnuanu Yes, I used grep at first and then I realized the -f flag does the same thing (filters by package name), as you can see in the example. Either works fine. Commented Jul 21, 2014 at 12:38

    If you are on Windows, use double quotes " instead of single quotes '. Like this: adb shell "pm list packages -f test" Or you will get weird errors. Commented Jul 16, 2015 at 9:28

    This doesn't work if the full name of the app or apk file does not contain the displayed name of the app. e.g. "Google Play Services" is com.google.android.gms, but this is basically impossible to find Commented Apr 2, 2017 at 6:29

    It's saying /data/app/br.org.academia.volp-… but there's no app directory inside /data. Why? Commented Jul 1, 2021 at 22:50

Just share the app from Google Play Store to somewhere, (by clicking on the share button in the app's page) and see the shared value.

You will see something like:
https://play.google.com/store/apps/details?id=com.my.packagename
(note: this app doesn't exist, it is only used as an example)

(If you can't find it in Google Play: You can long press on app icon and press on "Application info" Go to the bottom of the Android page, and then click on "App details in store")

  • This will only work if the app is published, if it is a test app or some qa app, this method wouldn't work. Commented Jul 8, 2024 at 23:50

You can look into the LogCat.

  1. Open the LogCat.

    • Either in Eclipse or on the cmd line if the device is connected to your PC.
    • Or on your mobile itself, using any app which allows you to view LogCat.

  2. Once LogCat is available, launch the app.

    The log corresponding to "ActivityManager" will display the activity started. It will usually be in the format: "Starting activity: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER]...".

However technical this approach might be, this is - IMHO - the best way to achieve knowledge about the launching activity for any of the installed apps.

Many apps can show the package name of the installed apps. I'm suggesting App Manager (available on F-Droid) which I currently use. Search the app name or the package name, and the the relevant entries would start showing up.

If you are proficient at using adb and Linux you can find it pretty quick using the linux command grep.

Just do:

adb shell ls -al /data/data/ | grep 'yourAppName'

You need root of course to be able to search in /data/data/

    So how do I become root? Root as in Linux root or root as in "root" your device? Commented Jul 13, 2019 at 12:18

    @NelsonGon "Rooting your device" means "gaining the ability to become root on the device". As such, in order to become root, your device must, by definition, be rooted. Commented Aug 1, 2020 at 4:09

Use Link2SD. It can list apps by name and show package names and other useful info.

  • You can search for the app's name in the Play Store and open that app. Now look into the URL. The last part of the URL is the package name, like id=com.google.

  • You can use adb shell and execute pm list packages -f. There are many operators, look into it. If you do not find all packages, then use dumpsys package command.

    On Oppo mobile, pm list packages provide me with 150 entries while dumpsys package provide me with 163 entries.

  • You can use an Android package name viewer application.

  • pm and dumpsys commands do list package names but how does one go around knowing which one belongs to the app of interest? Not all developers add app label in package name, so it is not obvious to guess. Commented Apr 29, 2021 at 9:03

Use App Manager app. It has plenty of features: sorting, filtering, finding, managing APK files, showing removed apps (since the time you've installed the app), root operations, and handling various split-APK files (APKS, APKM, XAPK) right from file manager apps.

Disclosure: I made the app.

On the phone, you can use Package Name Viewer 2.

You can browse through installed apps or search by app name.

I used an F-Droid package called "Applications Info" that provides a user-friendly UI for an app metadata which includes an application's full package name as well as the app's launcher activities. https://f-droid.org/en/packages/com.majeur.applicationsinfo/
