How to Find App Package & Activity in Android?

Test execution of Android applications in Testsigma (or in General) requires a few characteristic details about the application to locate the application and the specific feature to be tested. They are:

• App Package Name
• App Activity Name

Each Android app has a unique identifier, like a Java package name, like com.example.myapp. This identifier helps find your app on devices and the Google Play Store.

Moreover, an Android application will have multiple Activities or Pages, each containing elements like fields or buttons for testing.

In simple terms, An Activity in an Android Application is similar to a Web page in a Web Application or Website.

The App Package Name helps locate the application for testing purposes, while the App Activity Name pinpoints the specific page to be tested.

Prerequisite for ADB

• Android SDK should be installed and set up on the computer.

Steps to Find App Details Using ADB

Let us try finding the details of the Whatsapp application in this case.

1. Connect your Android device or emulator to your PC/Mac. Open the app you wish to inspect, in this case, WhatsApp.
2. Open a Command Prompt or Terminal window and run the adb devices command. This will display a list of connected devices with their unique device ID.

3. Use the following commands to retrive information about the currently open application:

   • For Mac/Linux: adb shell dumpsys window | grep -E 'mCurrentFocus'
   • For Windows: adb shell dumpsys window | find "mCurrentFocus"

4. The output will display the Android Application Package name and Application Activity name.

   • For example, here, com.whatsapp is the package name, and com.whatsapp.HomeActivity is the activity name.
