Make Work/PeriodicWork respectful of top-level package.

Currently, BaseWork has some stuff that the developer cares
about but it sits in the impl subpackage.  This is a large
refactor that cleans up a lot of the weirdness with our
file layout.

- Removed BaseWork entirely
  - PeriodicWork and Work no longer share a base class;
    there was no real reason they needed to
  - All constants moved to Constants.java
  - Moved the BaseWork.Builder to a new class of its own
    and made it an interface (because it shouldn't know
    about WorkSpecs, etc.)
- Made Work and PeriodicWork abstract, with abstract
  Builders (again, they shouldn't know about WorkSpecs
  and other implementation details)
  - Both classes have newBuilder methods that will
    instantiate concrete implementations; these in turn
    go to WorkManager (more on this below)
- The impl package contains concrete implementations of
  Work and PeriodicWork, backed by WorkSpecs
  - Note that these classes can no longer share a
    parent (this was causing all the confusion in
    ag/3346205) so there is some code duplication; I
    chose not to make a helper object for this
- WorkManager contains protected abstract methods to
  create Work and PeriodicWork builders that are backed
  by concrete implementations in WorkManagerImpl
  - This allows us to have only one exposed impl object
    (WorkManagerImpl in WorkManager.getInstance())
- Updated tests; a lot like the previously mentioned CL

Test: updated tests

AOSP Support Library Contribution Guide

Accepted Types of Contributions

  • Bug fixes (needs a corresponding bug report in b.android.com)
  • Each bug fix is expected to come with tests
  • Fixing spelling errors
  • Updating documentation
  • Adding new tests to the area that is not currently covered by tests

We are not currently accepting new modules, features, or behavior changes.

Checking Out the Code

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

Using Android Studio

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.

Optional - Full Build

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

Running Tests

Single Test Class or Method

  1. Open the desired test file in Android Studio.
  2. Right-click on a test class or @Test method name and select Run FooBarTest

Full Test Package

  1. In the project side panel open the desired module.
  2. Find the directory with the tests
  3. Right-click on the directory and select Run android.support.foobar

Running Sample Apps

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.

Making a change

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)?

Getting reviewed

  • After you run repo upload, open r.android.com
  • Sign in into your account (or create one if you do not have one yet)
  • Add an appropriate reviewer (use git log to find who did most modifications on the file you are fixing)
