Run KspTypeTests with javac This CL runs KspTypeTests w/ kapt to ensure they work the same. This required 3 changes: * KAPT replaces undefined types with `error.NonExistentClass` which means the `isError` check on TypeMirror is not reliable. I've updated Javac implementation to consider `error.NonExistentClass` as error as well. (Enabling correctErrorTypes should've prevented it but it does not seem to be happening in kotlin compile testing. I've not digged deeper because we would like to detect this even when developer did not enable correctErrorTypes option in kapt) -> In KSP, we had a similar fallback class in Room package. I've renamed it to use the same class as KAPT for consistency. * When types are resolved, KSP resolves bounded type variables to their extends bound instead of a non-type TypeMirror. Initially, we simply implemented extendsBound to return null for all KSP types which was inconsistent with Javac. This CL updates KspTypeArgumentType to implement extends bound properly (basically return the ksType). -> We no longer create KspTypeArgumentType for invariant types as they iare declared. -> If we receive a ksType whose declaration is a type parameter, we create KspTypeArgumentType. This might happen after calling asMemberOf. * When resolving nullability from KmType (kotlin-metadata type class), we read the nullability flag to make a decision, which is not enough to cover cases like `T : Foo?`. Now, if the KmType has an extendsBound, we also look at it. Bug: 160322705 Test: KspTypeTest, also extended existing tests to check for bounds Change-Id: Idc944519d0300804ea29cb88a0372978c1ffd072
Jetpack is a suite of libraries, tools, and guidance to help developers write high-quality apps easier. These components help you follow best practices, free you from writing boilerplate code, and simplify complex tasks, so you can focus on the code you care about.
Jetpack comprises the androidx.*
package libraries, unbundled from the platform APIs. This means that it offers backward compatibility and is updated more frequently than the Android platform, making sure you always have access to the latest and greatest versions of the Jetpack components.
Our official AARs and JARs binaries are distributed through Google Maven.
You can learn more about using it from Android Jetpack landing page.
For contributions via GitHub, see the GitHub Contribution Guide.
Note: The contributions workflow via GitHub is currently experimental - only contributions to the following projects are being accepted at this time:
When contributing to Jetpack, follow the code review etiquette.
We are not currently accepting new modules.
NOTE: You will need to use Linux or Mac OS. Building under Windows is not currently supported.
repo
(Repo is a tool that makes it easier to work with Git in the context of Android. For more information about Repo, see the Repo Command Reference)mkdir ~/bin PATH=~/bin:$PATH curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo chmod a+x ~/bin/repo
git config --global user.name "Your Name" git config --global user.email "you@example.com"
mkdir androidx-main cd androidx-main
repo
command to initialize the repository.repo init -u https://android.googlesource.com/platform/manifest -b androidx-main --partial-clone --clone-filter=blob:limit=10M
repo sync -j8 -c
You will use this command to sync your checkout in the future - it’s similar to git fetch
To open the project with the specific version of Android Studio recommended for developing:
cd path/to/checkout/frameworks/support/ ANDROIDX_PROJECTS=MAIN ./gradlew studio
and accept the license agreement when prompted. Now you're ready to edit, run, and test!
You can also the following sets of projects: ALL
, MAIN
, COMPOSE
, or FLAN
If you get “Unregistered VCS root detected” click “Add root” to enable git integration for Android Studio.
If you see any warnings (red underlines) run Build > Clean Project
.
You can do most of your work from Android Studio, however you can also build the full AndroidX library from command line:
cd path/to/checkout/frameworks/support/ ./gradlew createArchive
You can build maven artifacts locally, and test them directly in your app:
./gradlew createArchive
And put the following at the top of your ‘repositories’ property in your project build.gradle
file:
maven { url '/path/to/checkout/out/androidx/build/support_repo/' }
Our continuous integration system builds all in progress (and potentially unstable) libraries as new changes are merged. You can manually download these AARs and JARs for your experimentation.
Run FooBarTest
Run androidx.foobar
The AndroidX repository has a set of Android applications that exercise AndroidX code. These applications can be useful when you want to debug a real running application, or reproduce a problem interactively, before writing test code.
These applications are named either <libraryname>-integration-tests-testapp
, or support-\*-demos
(e.g. support-v4-demos
or support-leanback-demos
). You can run them by clicking Run > Run ...
and choosing the desired application.

AndroidX uses git to store all the binary Gradle dependencies. They are stored in prebuilts/androidx/internal
and prebuilts/androidx/external
directories in your checkout. All the dependencies in these directories are also available from google()
, jcenter()
, or mavenCentral()
. We store copies of these dependencies to have hermetic builds. You can pull in a new dependency using our importMaven tool.
