Continue modularisation by moving core activity classes that almost all activities depende on to a `core.activity` module. This includes core "helper" classes as well. Implement core.activity: - Contains BaseActivity, BottomSheetActivity - Contains LinkHelper and other utility classes used by activities Implement core.common.extensions: - Move ViewBindingExtensions and ViewExtensions here Implement core.common.util: - Move BlurHashDecoder and VersionName here Implement core.designsystem: - Holds common resources (animations, colours, drawables, etc) used through the app - Import "core.designsystem.R as DR" through the app to distinguish from the module's own resources Implement feature.login: - Move the LoginActivity and related code/resources to its own module Implement tools/mvstring - Moves string resources (and all translations) from one module to another |

Intents for starting activities to break circular dependencies.
A common approach for surfacing type-safe (ish) intents to start activities is for the activity-to-be-launched to provide a method in a companion object that returns the relevant intent, possibly taking additional parameters that will be included in the intent as extras.
E.g., if A wants to start B, B provides the method that returns the intent.
This introduces a dependency between A and B.
This is worse if B also wants to start A.
For example, if A is StatusListActivity
and B isViewThreadActivity
. The user might click a status in StatusListActivity
to view the thread, starting ViewThreadActivity
. But from the thread they might click a hashtag to view the list of statuses with that hashtag. Now StatusListActivity
and ViewThreadActivity
have a circular dependency.
Even if that doesn't happen the dependency means that any changes to B will trigger a rebuild of A, even if the changes to B are not relevant.
This package contains Intent
subclasses that should be used instead. The quadrant
plugin is used to generate constants that can be used to launch activities by name instead of by class, breaking the dependency chain.
If the activity's intent requires specific extras those are passed via the constructor, with companion object methods to extract them from the intent.
Using the intent classes from this package is enforced by a lint IntentDetector
which will warn if any intents are created using a class literal.
