Large fonts option

[lkernan]

I've installed EVMap onto my MG4 with F-Droid but the UI is extremely small.
Any chance we could have a zoom or large fonts option in the app settings?

Changing the default size in Android breaks the cars standard User Interface. Probably since the car maker never intended for us to break out of their UI or run third party apps.

The MG4 runs an older version of Android Automotive but doesn't include the app host so that UI isn't an option.

Hmm, it might be possible to change the scaling for the current app, but it's not something that's as well supported by existing libraries as changing the language or the dark mode setting.

Maybe this could be done the way EVMap used to implement the language setting before AppCompat supported it?
LocaleContextWrapper.kt

EVMap/app/src/main/java/net/vonforst/evmap/MapsActivity.kt

Lines 56 to 62 in 27cbb5e

	override fun attachBaseContext(newBase: Context) {
	return super.attachBaseContext(
	LocaleContextWrapper.wrap(
	newBase, PreferenceDataSource(newBase).language
	)
	);
	}

As an alternative, if you want to go the app host route, you could try installing the AOSP version of the app host. I have a fork of it with a working map implementation: https://github.com/johan12345/car-templates-host
However, Google hasn't updated the AOSP app host code for a couple years, so this won't support all of the latest features (like pan&zoom for the map).
