Known issue

Due to the way the browsers handle extensions, when an extension receives an update, content scripts in already-open web pages cannot use the Storage API, until the user reloads those web pages. In the context of this extension, it means that when the extension receives an update, as long as the user doesn't reload YouTube web pages, the extension cannot get the data regarding the user-preferred qualities.

A kind-of working solution

To provide a smooth user experience, I decided to use the last qualities that were fetched.

This solution is not perfect, since if the user wants to update the quality of the videos in the currently-open web pages using the popup page, it will not update dynamically. However, this is the only viable solution, as the alternative would be to auto-reload web pages, which would result in a bad user experience.

Phone/tablet

1. Install Android Studio on your operating system
2. Create an AVD (Android Virtual Device)
3. For a phone emulator, choose one that has Play Store preinstalled
4. For a tablet emulator, follow these steps after creating it to have Play Store preinstalled
5. Run the emulator:

    emulator @DEVICE_NAME

6. Download Kiwi Browser. I recommend creating a Google account specifically to be used with the emulator
7. • If you're using a single emulator while on Windows, you can run:

     pnpm build-pack:test-push

   • If you're testing on multiple emulators, and you're on PowerShell: First find the emulator ID:

     adb devices

     Then:

     pnpm build-pack:test; `
     $zip = "chrome-mv3-prod.zip"; `
     $destAndroid = "/storage/emulated/0/Download/$zip"; `
     adb -s ID shell rm $destAndroid; `
     adb -s ID push "build/$zip" $destAndroid;

     where you replace ID with the emulator ID
8. Side-load the extension on Kiwi

   
9. Select the ZIP in the Download folder
10. To reload, you must first remove the extension and then repeat steps 5-8

Sideloading onto your daily driver browser

After pnpm dev:

• Chromium-based browsers
  1. Open the extensions page
  2. Enable "Developer mode"
  3. Open youtube-auto-hd/build on your file system
  4. Drag-drop chrome-mv3-dev onto the extensions page
