be absolute, or relative to the appium server.

Answer 1

The path to your application APK is set incorrectly. I need to know your file structure to give the exact answer, but this is what I think is wrong.
Most likely you are trying to provide the application at C:\path\to\my\project\data\app\com.philips.sleepmapper.root-1\base.apk
If you run Appium in C:\path\to\my\project and you try to pass the relative path to the APK, you are missing the dot in the Appium test code. Change the path in the code to
File app = new File("./data/app/com.philips.sleepmapper.root-1/base.apk");
To make it work from any folder (absolute path) change the code to
File app = new File("C:\path\to\my\project\data\app\com.philips.sleepmapper.root-1\base.apk");
Remember to replace path\to\my\project with the real path you are using.
