Migrations

Below are some highlights on major refactoring/breaking changes

v5.2.0

KPref

In an effort to improve testing options, KPref has some updates to allow for in memory preferences during unit tests. While you can still use KPref like before as an object (provide the KPrefFactoryAndroid factory), it is recommended that you use some sort of dependency injection/service locator to provide the factory. An example can be found in the sample app test class.

Also note that to better support in memory preferences, reset() will clear the in memory content for both variants, meaning that in memory preferences will reset to default. Previously, in memory reset() did nothing.

AboutActivityBase

configBuilder was previously required in the constructor, but is now an open function so that activity fields can be used in the builder.

Gradle

v5.1.0

KPref

You’ll notice some errors with kpref imports. You can simply remove (optimize) them. Extension functions were converted to interfaces to allow for mocking, so imports are no longer necessary.

v5.0.0

Material Dialog Update

Material Dialog is now 3.x. This leads to a whole new API, but fortunately it is based around kotlin. Please refer to MD’s documents for the new methods.

Alongside such changes, :colorpicker is no longer as necessary. It exists mainly to provide an internal interface for other submodules.

After Material Dialog 2.x, a decision was made to enforce theming through xml styles only to avoid reflection. As a result, options to supply custom dialog colors are now removed (ie in the changelog dialog and color picker kprefs).

ProgressAnimator

ProgressAnimator has been completely rewritten to be an extension of ValueAnimator. This for the most part is not a breaking change, apart from the fact that creating an animator will not start it immediately. Make sure to call .start() to begin the animation.

Gradle Plugin

The plugin has been converted to kotlin objects. Now, usage is done through the classes directly, and no extensions are provided within the project. For instance, instead of using kauDependencies, we now use kau.Dependencies. There is also no longer a need to use apply plugin 'ca.allanwang.kau'; adding the plugin to the classpath suffices.

v4.0.1-alpha02

Anko has been removed

A lot of the methods are already implemented in KAU, and it was primarily imported for its doAsync methods. Now, they have been replaced with coroutines. Some methods have been copied over:

v4.0.0-alpha01

This is the first introduction of androidx. The goal is to just do a migration with minimal changes. Nothing has been changed internally, but the dependencies are updated. Notably, Android-Iconics split their Community Icons into two enums.

Kotterknife is also no longer deprecated. There are some use cases where kotlin-android-extensions isn’t the best, such as when multiple layout files are used, or when ids are defined in the id.xml. It is still recommended to use the extension where applicable.

v3.8.0

Along with the update to support Android Studio 3.1, a lot of changes have occurred with other dependencies and with lint.

Invalid Resource Id Equality

Resource ids can be negatives due to the bit overflow. Instead, INVALID_ID has been introduced to signify an unset or invalid id. Methods such as Context.string(id, fallback) now check against INVALID_ID through equality rather than using an inequality to address this.

Deprecate Kotterknife

Kotterknife has been deprecated in favour of kotlin-android-extensions. See official docs.

Update KPref

KPref has been slightly refactored internally. Preferences backed by StringSet can now go back to Set<String>

v3.6.0

startActivity

Before, startActivity attempted to bind a lot of options with defaults. Instead, we will now rely on the builder pattern so users may supply their own. Attributes like transition have been replaced with bundle functions such as withSceneTransitionAnimation(context). The ordering of the builder functions have also been unified so that bundleBuilder is always before intentBuilder.

kpref-activity

Click Events

Instead of passing parameters through the click functions, which were often unused, they will now be provided through extensions from KClick.

KClick holds the same values you’d expect (itemView, innerView (renamed), item), and adds on context and is loaded lazily where possible.

Title Res

In an attempt to make kprefs functional and thus easy to configure, two new functions, titleFun and descFun have been introduced. They will be triggered whenever kprefs are updated to get an up to date stringRes based on whatever conditions you specify. Most conditions are passed through anyways, which is why these functions supply no additional information.

You are still free to use the original descRes and the constructor title, which has been renamed to titleId to emphasis its immutability. Reloading kprefs are always done through the original titleId, regardless of the actual resource currently used.
