@ Quality @ Smart Eagle
Ask a few questions:
Book banner fiction now supports mobile phones of 2.3 and above
1, now adding hardware acceleration on the activity, may be on a phone that does not support hardware acceleration, will cause a control outside the WebView rendering problems? If the UC kernel fails to download, does using the native WebView in the SDK cause problems with turning on hardware acceleration?
2. What if we add hardware acceleration at the view level, for example: adding hardware acceleration only to UC WebView? Why do I have to be at the activity level?
All read
Zhi
1.1.4 View Level
We can disable hardware acceleration for individual view at run time phase. We can use the following code:
Myview.setlayertype (view.layer_type_software, NULL);
Note: Hardware acceleration at the view level is not possible at this stage.
Zhi
In essence, your activity enables hardware acceleration, but some view, which does not want to be treated as a layer alone, can be disabled, so that some layers will use software compositing, like PS, which merges multiple layers into a single bitmap, forming a layer within the hardware acceleration, and compositing with other hardware acceleration layers.
Wei
With hardware acceleration at the activity level, the main concern is the impact on the activity's non-webview controls, because compatibility with some low-end phones can render
Zhi
So I said the setup of hardware acceleration options is a more complicated process.
Zhi
According to the experience of Personal Edition, it consists of three steps.
Chan Yan

2, through the view of the Dispatchdraw (canvas canvas) interface obtained by the canvas parameters (first draw), to determine whether the canvas is a hardware canvas, if not, disable AC.
3. Initialize the kernel with the final AC value.

@ wei This I have no experience, do not know whether setting this option will cause other view problems, but should not it? Hardware acceleration is supported only for versions above 14.

Excuse me:
Failed to download the UC kernel in SDK or the first time I loaded the SDK, using the native WebView in the kernel
In this scenario, the Utils.checksupportsamplerexternaloes () method can be used to determine if I am fit to turn on hardware acceleration? (The native WebView is used in this scenario and does not want to turn on hardware acceleration)
Zhi
@ Zhang Zanyan checksupportsamplerexternaloes () just stand at the kernel angle and check to see if the GL API used by the kernel meets the requirements.
Zhi
@ can rock theoretically, the activity may work in hardware acceleration mode, but because the kernel's OpenGL API is not supported, it is also possible to use software to draw webview.
Zhi
@ wei Checksupportsamplerexternaloes () does not require the UC kernel to execute, it is just some check.

@ Quality Hi, we are now doing the SDK for Android This browser framework, there are currently two issues with the introduction of the UC kernel:
1, the document says 4.0 below does not support hardware acceleration, because our SDK needs to be compatible with 4.0 below, so we need to have a judgment on the current version and then turn on hardware acceleration, the problem is that if hardware acceleration is the activity level, every activity that wants to use our SDK needs to make a judgment, because do not know except WEBV If other controls outside of Iew require hardware acceleration, then the abstraction of the SDK is not too good! The question is, can you use the view-level hardware acceleration? Or the view level and the acitvity level, what is the difference between the bottom of our kernel?
2, more than 4.0 turn on hardware acceleration, the first time into the application to load the UC kernel, this is still native webview, hardware acceleration will also affect the native WebView. Is it still necessary to determine if the UC kernel is loading and then turning on hardware acceleration?
Zhi
Hardware acceleration, not when you want to drive.
Zhi
Before the first screen is drawn, it must be determined.
Wei
Yes, so before the activity is loaded, you need to determine
Zhi
What we provide externally as an SDK is an acceleration option setting plus a check interface.
Zhi
Similarly, you can also set, whether an AC initialization option, provide an API check (inside the suggestion plus your check logic, as well as our external Checksamples interface), can be.
Wei
What's the difference between the view level and the acitvity level hardware acceleration kernel bottom?
Zhi
We recommend that you look at the documentation for the rendering schema first.
Zhi
The activity is rendered from the Viewroot
Zhi
The beginning.
Zhi
The following view tree nodes, by some rules, can be organized into multiple layers that can be represented individually.
Wei
But there are some specific view I if I do not need to speed up rendering, it is necessary to set the
Zhi
And some view, you can display the declaration, you do not want to be a separate display layer (that is, not the hardware accelerator layer), its rendering is first and other layers merged into a bitmap, and finally become a hardware accelerator layer, and finally the other hardware acceleration layer on the GPU to be synthesized.
Wei
Good
Zhi
I pull a rendering of the great God answer your questions will be more professional.
Wei
The first time I entered, the native WebView I also want to display the statement, do not do hardware acceleration it
Zhi the Yixu into the group
Wei
You know, thanks.
Zhi
Actually, it's very simple. All you have to do is determine if the activity is going to turn on AC, then use an algorithm: (Own open condition && UC Kernel open condition && system kernel on condition)
Zhi
Where you have open conditions, can be the memory size of the judgment, CPU core count, the system version of the judgment.
Zhi
The condition of the UC kernel is the Checksamplesxxxxxx interface.
Zhi
The condition of the system kernel is that you filter out the characteristics of the models that have found the stability problem.
Chan Yan
