This task will allow you to switch between all your available Android themes (Styles) if using a Google Pixel device, Pixel Experience custom ROM, or any other custom ROM based on Pixel devices.
- This task was based on a request from a Reddit user. (reference)
- The 'android.permission.WRITE_SECURE_SETTINGS' permission will have to be granted to tasker for non-rooted devices (guide), and 'android.permission.WRITE_SETTINGS' too.
- All of the properties from every action were based on my current device and ROM, so I would suggest you to find and use yours instead. Just to avoid possible problems.
- Styles are managed by the Google Wallpaper app, but its settings could exists or not on the Secure Settings table (or maybe other), as custom ROM devs can make some redirection for the app to not allow it to save/load content from Settings tables. If it's your situation, try looking at '/data/data/.../shared_prefs/*' (root required) to try changing app's values by this way.
