Generate ProGuard rules to keep generated adapters Once an adapter class is generated, also generate a ProGuard configuration file that only marks the generated class as a seed (entry point to be kept) if the peer class is ever instantiated. If the generated classes are always kept (since they are referenced through reflection) then the peer class is always kept. This can cause large amounts of code to remain in the final binary that is unreferenced. This change depends on ProGuard being able to pull the configuration files from inside the jar file. A new Unused lifecycle observer was added as a canary to ensure that ProGuard can be taught to use the new keep rules. Test: Rebuilt the integration test APK and verified the keep rules were generated. Test: :lifecycle:compiler unit tests Bug: 65293954 Change-Id: I56c3d8a228e74048eac057ac2da265be046c45fc
We are not currently accepting new modules, features, or behavior changes.
NOTE: You will need to use Linux or Mac OS. Building under Windows is not currently supported.
Follow the “Downloading the Source” guide to install and set up repo
tool, but instead of running the listed repo
commands to initialize the repository, run the folowing:
repo init -u https://android.googlesource.com/platform/manifest -b ub-supportlib-master
Now your repository is set to pull only what you need for building and running support library. Download the code (and grab a coffee while we pull down 7GB):
repo sync -j8 -c
You will use this command to sync your checkout in the future - it’s similar to git fetch
Open path/to/checkout/frameworks/support/
in Android Studio. Now you're ready edit, run, and test!
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 support library from command line:
cd path/to/checkout/frameworks/support/ ./gradlew createArchive
Run FooBarTest
Run android.support.foobar
Support library has a set of Android applications that exercise support library 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 support-*-demos (e.g. support-4v-demos or support-leanback-demos. You can run them by clicking Run > Run ...
and choosing the desired application.
cd path/to/checkout/frameworks/support/ repo start my_branch_name . (make needed modifications) git commit -a repo upload --current-branch .
If you see the following prompt, choose always
:
Run hook scripts from https://android.googlesource.com/platform/manifest (yes/always/NO)?
