Add nullable versions of ColumnTypeAdapters for KSP With javac, Room's type converters support nullable types (e.g. java.lang.Boolean) using its boxed primtives. This does not work well with KSP where we have proper type nullability which is considered in type equality. This CL adds nullable versions of boxed ColumnTypeAdapters. It is limited to KSP and also still generates the same code for declared types even when we know the type is not nullable. This decision can be changed in the future to generate better code (we'll need to do that for kotlin codegen). I've limited these null aware adapters to KSP because in javac, type comparison ignores nullability. I've also fixed a possible bug in String and byte[] converters. Right now, when reading values, they always call cursor getString/Blob which happens to return null but appearantly it is not guarateed so now we generate code that checks for null. Bug: 160322705 Bug: 176104406 Test: BasicColumnTypeAdaptersTests are now run with KSP as well and also test for nullable boxed types Test: SQLTypeAffinityTest Change-Id: Ib4e74f54fdb5ab83e58a8287c5324f434cb0fddd
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 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.
