The second approach to know the package and activity details is to use the Appium GUI app. When we use Appium to install the app on the emulator/device, it also loads the Package details and the Launch Activity. So, the steps to be followed are as listed:

1. Launch the Emulator/Device.
2. Launch the Appium GUI app.
3. Select the App path parameter and browse to the APK package.
4. Click on Launch.
5. This will start the Appium server; now click on the Inspector icon.
6. Click on Stop (to stop the Appium server).
7. Click on the Android icon in the Appium GUI app.
8. Select the Package checkbox and click on the dropdown; it will show the value from the last APK file installed.
9. Select the Launch Activity checkbox and click on the dropdown; it will show all the values from the last APK file installed.
