With this commit, activities will automatically change theme between day/night if `night-mode` `termux.properties` is not set or is set to `system` without requiring app restart.
Dialog theming will be fully added in a later commit and may currently be in an inconsistent state or have crashes.
The `uiMode` has been removed from `configChanges` of `TermuxActivity`, this may cause termux app to restart if samsung DEX mode is changed, if it does, then users should report it so that it can be fixed by re-adding the value and ignoring the change inside `TermuxActivity.onConfigurationChanged()`. The docs don't state if its necessary. Check related pull request #1446.
Running `termux-reload-settings` will also restart `TermuxActivity`, the activity data should be preserved.
This will not break existing `use-black-ui` settings for users and it will automatically be converted to `night-mode` when properties are loaded from disk but a deprecation message will be logged.
This `night-mode` key can be used to set the day/night theme variant for activities used by termux app and its plugin. The user can set a string value to `true` to force use dark variant of theme, `false` to force use light variant of theme or `system` to automatically set theme based on current system settings. The default value is still `system`. The app must be restarted for changes to take effect for existing activities, including main terminal `TermuxActivity`.
This is required since "theme != night mode". In future custom theme or color support may be provided that will have both dark and night modes for the same theme.
Termux will now automatically request legacy `WRITE_EXTERNAL_STORAGE` or `MANAGE_EXTERNAL_STORAGE` permissions if targeting targetSdkVersion `30` (android `11`) and running on sdk `30` (android `11`) and higher when `termux-setup-storage` is run.
Functions have been added to `PermissionUtils` to automatically check and request either permission depending on app `targetSdkVersion` and android version. Functions have been added to `PackagUtils` to get `requestLegacyExternalStorage` value from app manifest if added. If legacy storage is possible, then it must be set to `true`. Check `PermissionUtils.checkAndRequestLegacyOrManageExternalStoragePermission()`, `PermissionUtils.isLegacyExternalStoragePossible()` and `PermissionUtils.checkIfHasRequestedLegacyExternalStorage()` for details.
ContextCompat.checkSelfPermission() may return true for permissions not even requested so it now checked if permissions are even requested in app manifest before checking if they are granted and before asking for permission to be granted.
Also some general improvements in code quality, including using ActivityUtils to request non-standard permissions and added support for AppCompatActivity instances to request permissions in addition to Activity instances.
