Fixes #239(Theme option)

[StellarSand]

As discussed in #309 splitting theme into a separate PR. Haven't added checkbox yet.

Did you have need help to continue PR ?
Is it more easy for you, if we drop API 21 and API 22 support ?

[StellarSand]

Hi. I was little busy with other things and hence could not continue. I will implement the checkbox tomorrow. If all works well there's no need to drop support for API 21 & 22. If not, we'll think about it later. I guess the only help needed is implementing preferences wherever I've added TODO comments. Will let you know after I try tomorrow.

Ok,
To implement preferences, you can check PR #273
I think switch is better to enable OLED mode
https://m3.material.io/components/switch/overview
Do you think, it's possible to add switch in pop-up ?

I suggest to add app:showAsAction="ifRoom" attributes in about_menu.xml and this icon https://fonts.google.com/icons?selected=Material%20Symbols%20Outlined%3Apalette%3AFILL%400%3Bwght%40400%3BGRAD%400%3Bopsz%4048

Switch ✔️
OK button ✔️
Icon ✔️
Preferences ❌

To implement preferences, you can find more information here
https://developer.android.com/topic/libraries/architecture/datastore

I think to start implementation, you need to add a new default value here:

exodus-android-app/app/src/main/java/org/eu/exodus_privacy/exodusprivacy/manager/storage/ExodusDataStoreRepository.kt

Line 33 in 78f5d38

private fun defaults(): String {

To check value, you can check this function

exodus-android-app/app/src/main/java/org/eu/exodus_privacy/exodusprivacy/MainActivity.kt

Line 97 in 78f5d38

private fun startInitial() {

To update value, you can check this

exodus-android-app/app/src/main/java/org/eu/exodus_privacy/exodusprivacy/MainActivityViewModel.kt

Line 27 in 78f5d38

fun saveNotificationPermissionRequested(status: Boolean) {

Is it easier for you, if we use android x preference?

[StellarSand]

Hello. I've been very busy and unwell recently. I'll take a look at this once I recover soon.

[StellarSand]

Tried my best, but no luck. Closing it down with a classic "skill issue." If someone else feels up to it, they can handle the preferences stuff.
