How to Use APK Expansion Files to Test Your Android App on Real Devices
What is a dummy apk file?
A dummy apk file is a fake or simulated Android application package (APK) that does not contain any real functionality or logic. It is usually created for testing, debugging, or demonstration purposes, such as checking the layout, design, compatibility, performance, or security of an app.
A dummy apk file has the same format and structure as a real APK file, which is a compressed archive that contains the code and resources of an Android app. However, a dummy apk file does not execute any code or perform any actions when installed or launched on an Android device.
