Jetifier: remove dangling refs from the const pool. Bytecode generated by the compiler contained some extra references to androidx even after dejetification. These references were actually not used during the runtime so ASM silently kicked them out during the rewrite. That didn't trigger change detection so jetifier did not detect that file was changed and did not update the bytecode generated by ASM. This happened only for files that had no direct androidx usage but still had some unsused references in constant pool. To be more defensive we now update bytecode for every file that was processed by ASM but only mark the file changed in case there is a real remapping of some reference using jetifier. This allows us to keep files up to date but only save those archives that had at least one real reference rewrite. Since we don't want to rewrite archives that have no support usage. Bug: b/64833662 Test: Manually inspected that the generated class file no longer contains androidx reference. Change-Id: If492baf77d119e6c5df47be8ab73c7ee5507c28b
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
If you intend to repeatedly make changes to Support Library and to wish to see the results in your app, and you don't want to have to repeatedly build them as separate Gradle projects, you can configure your app build to build Support Library too
Run FooBarTestRun android.support.foobarSupport 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)?
