Updating emulator version became simple by Bug 1718341. Then just updating emulator version caused a lot of test failure.

• Test result of emulator of Adnroid 24(default)
• Test result of emulator of Adnroid 25
• Test result of emulator of Adnroid 27
• Test result of emulator of Adnroid 28
• Test result of emulator of Adnroid 30
• Test result of emulator of Adnroid 33

Latest Android emulator 33 addressed some test failures of accelerated canvas. But test failures of R-swr-nofis was not addressed.

• Test result of enabling accelerated canvas on emulator of Adnroid 24(default)
• Test result of enabling accelerated canvas on emulator of Adnroid 33

Sotaro, do you know whether accelerated canvas works on a device running Android 7 (SDK level 24)? ie is it actually an emulator problem, or is it a problem with older versions of Android?

Comment 4

[Sotaro Ikeda [:sotaro]]

I do not have an Android 7 device, but it should be an emulator specific problem.

From Bug 1794380 comment9, Android 8.0 Pixel2 did not cause the problem. By modifying test, it seems to possible to check if accelerated canvas works on Android 7.0 MotoG5.

From android 25 emulator, the followings R-nofis tests' failures were addressed. But several failures of R-swr-nofis were not addressed.

(In reply to Sotaro Ikeda [:sotaro] from comment #5)

But several failures of R-swr-nofis were not addressed.

It was caused by current implementation of RenderAndroidSurfaceTextureHost. On android emulator, single buffer mode SurfaceTexture is not used. Since single buffer mode SurfaceTexture does not work on Android Emulator.

When SurfaceTexture is not single buffer mode, RenderAndroidSurfaceTextureHost calls mSurfTex->UpdateTexImage() in RenderAndroidSurfaceTextureHost::Lock(). It is necessary for video playback with hardware WebRender. But it does not work with WebRender (Software OpenGL).

accelerated canvas seemed to cause timeout failures in Wd1 mda1 mda2 of debug build on Android emulator.

Android emulator does not use hardware GPU. It seems to be related.
