Build me a simple Android app called Game Resolution Scaler that helps people with lower end phones run heavy games more smoothly by lowering the device resolution and adjusting DPI automatically.

It should work on older Android versions from around Android 5 up to Android 11 if possible. When the user opens it, make the flow easy to understand, with a clean UI that lets them choose root mode or non root mode, set a custom resolution, restore the original resolution and DPI, and launch selected games. Include clear warnings for risky options like killing other apps before starting a game.

For rooted phones, support extra options like aggressive memory cleanup and killing non system apps before launching a game. For non rooted phones, guide the user through granting the needed secure settings permission with USB debugging and a computer.

Keep it lightweight, simple, and beginner friendly. Use Java for the Android app, and look up current Android docs online if needed.
