Preserve type in query result adapters This CL fixes a bug that happens only in KSP pipeline. When a dao method returns List<T> where T maps to a primitive in java (e.g. List<Long>) and non null, Room would end up using a primitive column row adapter for T. ListQueryResultAdapter previously read its type argument from the row adapter, which is a problem because the row adapter has primitive type. I've updated ListQueryResultAdapter to explicitly receive the type on construction instead of relying on the row adapter. Same case for ImmutableList. Both Java and Guava optional hits a similar issue as well. In both cases, I changed the row adapter query to also use a nullable type when querying to ensure that we'll prefer a row adapter that can return null values. Otherwise, in a case like Optional<Int>, we would return Optional.of(0) because we would look for a non-null row adapter even though Optional semantically accepts nullable. I've also added more tests for Binders. They were not failing without the change but I decided to keep them. Unfortunately, some of these tests fail with KAPT until b/146755796 is fixed. To be able to disable them for kapt, I've added a BuildConfig field to pass down whether ksp was used during compilation.

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.
