  Message : docs: Document how to use ANGLE on Android This CL creates a new page that is dedicated to building and using ANGLE for Android. With Android 10 released, now anyone can try out ANGLE as their GLES driver for debuggable apps. It can also be loaded for any app if the user has root access. Also migrated existing Android build instructions with updates from the team.

• # ANGLE + dEQP
  
  drawElements (dEQP) is a very robust and comprehensive set of open-source
  tests for GLES2, GLES3+ and EGL. They provide a huge net of coverage for
  almost every GL API feature. ANGLE by default builds dEQP testing targets for
  testing against GLES 2, GLES 3, EGL, and GLES 3.1 (on supported platforms).
  
  ## How to build dEQP
  
  You should have dEQP as a target if you followed the [DevSetup](DevSetup.md)
  instructions. Current targets:
  
    * `angle_deqp_gles2_tests` for GLES 2.0 tests
    * `angle_deqp_gles2_no_gtest` for GLES 2.0 tests without google test suite
    * `angle_deqp_gles3_tests` for GLES 3.0 tests
    * `angle_deqp_gles3_no_gtest` for GLES 3.0 tests without google test suite
    * `angle_deqp_egl_tests` for EGL 1.x tests
    * `angle_deqp_egl_no_gtest` for EGL 1.x tests without google test suite
    * `angle_deqp_gles31_tests` for GLES 3.1 tests (currently very experimental)
    * `angle_deqp_gles31_no_gtest` for GLES 3.1 tests (currently very experimental) without google test suite
  
  ## How to use dEQP
  
  Note:
  To run an individual test, use the `--deqp-case` flag on any of the `no_gtest` targets.
  It supports simple wildcard support. For example: `--deqp-case=dEQP-
  GLES2.functional.shaders.linkage.*`.
  The `gtest` targets support wildcards via the `--gtest_filter` argument,
  but have different test names.
  
  The tests lists are sourced from the Android CTS masters in
  `third_party/VK-GL-CTS/src/android/cts/master`. See `gles2-master.txt`,
  `gles3-master.txt`, `gles31-master.txt` and `egl-master.txt`.
  
  If you're running a full test suite, it might take very long time. Running in
  Debug is only useful to isolate and fix particular failures, Release will give
  a better sense of total passing rate.
  
  ### Choosing a Renderer
  
  By default ANGLE tests with D3D11 on Windows, GLES on mobile and Desktop GL otherwise.
  To specify the exact platform for ANGLE + dEQP, use the arguments:
  
    * `--deqp-egl-display-type=angle-d3d11` for D3D11 (highest available feature level)
    * `--deqp-egl-display-type=angle-d3d9` for D3D9
    * `--deqp-egl-display-type=angle-d3d11-fl93` for D3D11 Feature level 9_3
    * `--deqp-egl-display-type=angle-gl` for OpenGL Desktop (OSX, Linux and Windows)
    * `--deqp-egl-display-type=angle-gles` for OpenGL ES (Android/ChromeOS, some Windows platforms)
    * `--deqp-egl-display-type=angle-metal` for Metal (Mac)
    * `--deqp-egl-display-type=angle-swiftshader` for Vulkan with SwiftShader as driver (Android, Linux, Mac, Windows)
    * `--deqp-egl-display-type=angle-vulkan` for Vulkan (Android, Linux, Windows)
  
  The flag `--use-angle=X` has the same effect as `--deqp-egl-display-type=angle-X`.
  
  ### Check your results
  
  If run from Visual Studio 2015, dEQP generates a test log to
  `out/sln/obj/src/tests/TestResults.qpa`. To view the test log information, you'll need to
  use the open-source GUI
  [Cherry](https://android.googlesource.com/platform/external/cherry). ANGLE
  checks out a copy of Cherry to `angle/third_party/cherry` when you sync with
  gclient. Note, if you are using ninja or another build system, the qpa file
  will be located in your working directory.
  
  See the [official Cherry README](https://android.googlesource.com/platform/external/cherry/+/master/README)
  for instructions on how to run Cherry on Linux or Windows.
  
  ### GoogleTest, ANGLE and dEQP
  
  ANGLE also supports the same set of targets built with GoogleTest, for running
  on the bots. We don't currently recommend using these for local debugging, but
  we do maintain lists of test expectations in `src/tests/deqp_support`. When
  you fix tests, please remove the suppression(s) from the relevant files!
  
  ### Running dEQP on Android
  
  Running the tests not using the test runner is tricky, but is necessary in order to get a complete TestResults.qpa from the dEQP tests (since the runner shards the tests, only the results of the last shard will be available when using the test runner). First, use the runner to install the APK, test data and test expectations on the device. After the tests start running, the test runner can be stopped with Ctrl+C. Then, run
  ```
  adb shell am start -a android.intent.action.MAIN -n org.chromium.native_test/.NativeUnitTestNativeActivity -e org.chromium.native_test.NativeTest.StdoutFile /sdcard/chromium_tests_root/out.txt
  ```
  After the tests finish, get the results with
  ```
  adb pull /sdcard/chromium_tests_root/third_party/angle/third_party/deqp/src/data/TestResults.qpa .
  ```
  Note: this location might change, one can double-check with `adb logcat -d | grep qpa`.
