ADB Tips for Appium: How to Locate Android Package and Activity Names Easily

In mobile test automation, Appium is a widely used tool for testing Android and iOS applications. It helps testers automate actions on various devices and environments. A key part of setting up Appium tests is correctly identifying the package and activity names of the Android app you want to test. These names serve as unique identifiers, helping Appium locate and launch the application on the device. Without this information, Appium can’t access the app, making the automation setup incomplete.

This is where the Android Debug Bridge, or ADB, comes in as a powerful tool in mobile automation. ADB allows testers to communicate directly with Android devices, enabling essential actions like retrieving package and activity details, monitoring system logs, and more. By using ADB commands, we can easily extract the exact package and activity names needed for Appium automation, simplifying the setup process and enhancing testing accuracy.

📌Understanding Package and Activity Names

When working with Android applications, especially in the context of automation, understanding package and activity names is crucial. These two elements act as the key identifiers for any Android app, guiding tools like Appium to locate, launch, and interact with specific app components.

What is a Package Name?

The package name serves as a unique identifier for every Android application. It’s assigned when the app is created, usually following a reverse domain name format (e.g., com.example.myapp). This identifier differentiates one app from another, much like a unique address.

For example:

• In the Facebook app, the package name could be com.facebook.katana.
• For WhatsApp, it’s com.whatsapp.

The package name is essential because:

1. It uniquely identifies an app on a device.
2. It’s used by the Google Play Store to manage listings, permissions, and updates.
3. It allows automation tools like Appium to target the correct app during testing.

What is an Activity Name?

An activity in Android is a screen or a component that allows user interaction. Each screen within an app is represented by an activity, and the activity name indicates which specific screen Appium should start with.

For instance, in a social media app, MainActivity might represent the home screen, while LoginActivity could be the login screen.

Activity names help Appium:

1. Identify which screen to begin automation on.
2. Bypass certain screens to start tests exactly where required.
3. Simplify navigation and improve testing efficiency.

Example of Package and Activity Names in Appium

If we’re automating the login screen of a banking app with package com.bank.app and activity LoginActivity, we configure Appium like this:

Example code:

Here:

• appPackage tells Appium which app to open.
• appActivity directs Appium to start on the specified screen, optimizing the testing process. How Package and Activity Names Help in Launching and Automating Apps Using Appium In Appium, automation of Android apps requires specific “capabilities” to communicate with the app. Two of the most essential capabilities are the package name and activity name.
