- Android Support v4 (Development Framework)
The Android Support Library is not actually a single library, but rather a collection of libraries that can roughly be divided into two groups: compatibility and component libraries. For details, please see
Understanding the Android Support Library.
- AndroidX Activity (Utility)
provides the base Activity subclass and the relevant hooks to build a composable structure on top.
- Android Jetpack Annotations (Utility)
library that contains the annotations for Android Jetpack.
- AppCompat (Utility)
support newer Android features on older Android versions.
- Constraint Layout Library (Utility)
library to reduce the number of nested views needed.
- Androidx Core (Utility)
a static library that you can add to your Android application in order to use APIs that are either not available for older platform versions or utility APIs that aren't a part of the framework APIs.
- DataStore (Development Aid)
stores data asynchronously, consistently, and transactionally, overcoming some of the drawbacks of SharedPreferences.
- Androidx Fragment (Development Aid)
- androidx.legacy (Utility)
a static library that you can add to your Android application in order to use APIs that are either not available for older platform versions or utility APIs that aren't a part of the framework APIs.
- Lifecycle (Utility)
perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.
- Media (Utility)
share media contents and controls with other apps.
- Preference (Utility)
a library to build interactive settings screens without needing to interact with device storage or manage the UI.
- Android Activity Saved State (Utility)
provides the base Activity subclass and the relevant hooks to build a composable structure on top.
- Transition (UI Component)
animates motion in the UI with starting and ending layouts.
- Android Jetpack VersionedParcelable (Utility)
Provides a stable but relatively compact binary serialization format that can be passed across processes or persisted safely.
- AndroidX Widget ViewPager2 (UI Component)
replaces AndroidX ViewPager, addressing most of its predecessor’s pain-points, including right-to-left layout support, vertical orientation, modifiable Fragment collections, etc.
- Butter Knife (Utility)
binds Android views and callbacks to fields and methods.
- FasterXML Jackson (Utility)
a fast and compliant streaming JSON parser/writer with a StAX-like API and support for marshalling/unmarshalling POJOs via annotations.
- Google Material Design (Utility)
library to help with material design guidelines.
- Google Protocol Buffers (Utility)
library that deals with Protocol Buffers (a.k.a., protobuf) – Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data.
- DBFlow (Utility)
ORM android database library.
- Picasso (Utility)
image downloading and caching library.
- JavaX Dependency Injection (Utility)
specifies a means for obtaining objects in such a way as to maximize reusability, testability and maintainability compared to traditional approaches such as constructors, factories, and service locators (e.g., JNDI). This process, known as dependency injection, is beneficial to most nontrivial applications.
- Kotlin (Utility)
The Kotlin Programming Language
- kotlinx.coroutines (Utility)
library support for Kotlin coroutines.
