Fix schema identity has to be stable Room v1 has a bug where it generates the schema identity from the create table query, which was OK when it was written (because Room considered column order as part of schema) but not anymore (since we don't enforce column order). The problem is fixed by creating both legacy and new identity hash so that RoomOpenHelper can validate old database. Unfortunately, this is a large CL because we don't want to update schema json files so all of the Schema data classes implements a new schema equality api which checks if the schema description of two entities are the same, even though their SQL might be different. (e.g. the column order in an entity or the auto generated index name) Since we are not overriding json files, the fix will only take effect after a migration. Bug: 64290754 Test: android.arch.persistence.room.migration.bundle.* Change-Id: I44959a353ac919850e2606ca704008ea57da7313
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)?
