Selendroid-test-app: https://mvnrepository.com/artifact/io.selendroid/selendroid-test-app

The path to APK file:

Download desired android application file from Google Play Store and save the desired location on the computer. We create a file object which represents the actual apk file on the disk. I placed my apk file in the folder '/home/jannat/apk/'.

// Path of the android application file (apk)

File appDir = new File("/home/jannat/apk");

// path with android application name

File app = new File(appDir, "selendroid-test-app-0.17.0.apk");

// An absolute local path to the APK file

capabilities.setCapability(“app”, app.getAbsolutePath());

Handle already installed an android application using appium:

We need to provide android application package name and activity name which help to open already installed application.

Please browse to below url to find android application package name and activity name.

https://hiromia.blogspot.com/2017/02/how-to-find-package-name-and-launcher.html

// Java package of the tested Android app

capabilities.setCapability("appPackage", "io.selendroid.testapp");

// An activity name for the Android activity you want to run from your package.

capabilities.setCapability("appActivity", "io.selendroid.testapp.HomeScreenActivity");
