Make Font Resources XML working on Android N or before device. This addresses several issues: - API 16 to API 25 There are two main issues. -- AssetManager failed to open file by path name. Fixed by using Resources.openRawResource instead of AssetManager.openNonAssetFd. -- TextView's style is ignored. Before API 26, there is no way to create Typeface from multiple font files. If Typeface is created from multiple font files, TextView will select correct font based on style information of them. However, this is impossible on API 25 or before. So select best match font from given list and create Typeface with it. At the same time, there is a concept "fakeBold" and "fakeItalic" on Android. If even the best matched Typeface is not usable for requested style, TextView makes bold/italic glyph with transforming available glyph. Since we does font selection by ourselves, needs to set fake bold/italic by manual too. - API 16 - API 19 Styled typeface can be created from another Typeface like as follows. Typeface boldTypeface = Typeface.create(baseTypeface, Typeface.BOLD); The passed style information can be retrieved by Typeface.getStyle() but this doesn't return real value on API 19 or before. Thus, introduce TypefaceHolder to hold actually using weight/italic information. Known Issues: - API 15 or before Still not working even after this patch. TypedArray returns false for hasValue with R.styleable.TextAppearance_android_fontFamily. - API 21 - API 25 The skew angle is sharper. Bug: 37754362 Test: ./gradlew support-compat:connectedDebugAndroidTest passes on API 15,16,17,18,19,21,23,25,26 Test: Test App attached issue 37754362 show the same result on API 16,17,18,19,21,23,25 except for fake italic angle. Screenshots is available on issue tracker. Change-Id: I6bd615774be55981289f5f3b88f3d71fa1b39014
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)?
