screen.noun explanationSurfaceflinger : Android system service, which is responsible for managing the frame buffer of the Android system, which is the display screen. Surface : Each window of the Android app corresponds to a canvas (canvas), or surface, which can be understood as a window for Android apps. With the de

Graphics can be rendered in two categories: software rendering and hardware rendering. Software rendering relies on the CPU to calculate various coordinates and draw, mainly to occupy memory, hardware rendering is GPU-based, mainly video memory, the general 3D graphics progr

Profile GPU RenderingThe Android Developer option provides the profile GPU rendering feature for real-time display on the screen of how long the GPU takes to render each frame image (in ms).The rendering time is represented by a h

I. Description of the problem The setting "Use software rendering without GPU rendering" cannot be changed in IE9. Second, the method The "Use software rendering without GPU rendering" setting is turned on and grayed out t

Surface member function lock to obtain a Canvas, which is essentially a Graphic Buffer to the SurfaceFlinger service Dequeue. Canvas encapsulates the 2D UI rendering interface provided by Skia and is drawn on the previously obtained Graphic Buffer. After the rendering is complete, the Android application process then calls the unlockAndPost request of the Canvas

. Whenever a window needs to draw the UI, it calls its associated surface's member function lock to get a canvas, essentially dequeue a graphic Buffer to the Surfaceflinger service. The canvas encapsulates the 2D UI drawing interface provided by Skia and is drawn on top of the graphic buffer previously obtained. After drawing is completed, the Android application process then invokes the previously obtained member function of the canvas unlockandpost

Android text rendering A common method for rendering text using OpenGL is to calculate a texture image that contains the displayed text, which usually uses a complicated packaging algorithm to minimize the redundant part of the texture, before creating such an image, you must be clear about the font used when the application is running, including the font shape,

adding the turbine, it is possible to compress the air to increase the oxygen content and actively inhale the air supply for combustion.The scary technology is to improve the efficiency of instruction transmission between CPU and GPU by Emui in software, and finally improve graphics processing efficiency without changing hardware conditions.How scary is the technology to add a turbo to the bottom system of the phone? The data from the Glory play show

1.Glossary GPU: Graphic Processing Unit (graphics processor) OpenGL: Open Graphic Library defines the specification of a cross-programming language and cross-platform programming interface. Different vendors have different implementation methods. It is mainly used for 3D image (two-dimensional) painting. Surfaceflinger:Dynamic library in Android that is responsible for surface overlay and hybrid operations

Basic knowledgeCPU: central processing Unit, it integrates operation, buffering, control and other units, including drawing function. The CPU handles objects as multidimensional graphics, and textures (Bitmaps, drawables, etc. are packaged together into a uniform texture).GPU: A CPU-like processor specifically designed to handle graphics, to help speed up grid operations, and, of course, to have the appropriate cache data (such as caching already rast

through Grglinterface.The grglinterface contains the interface that corresponds to OpenGL es.Webgraphicscontext3dcommandbufferimpl::creategrglinterface () callSkia_bindings::createcommandbufferskiaglbinding () generates Grglinterface,and binds the grglinterface contained interfaces to the Webgraphicscontext3dcommandbufferimpl corresponding interfaces.Grglinterface was passed to Grcontext. This action is called by Grglinterface in GrcontextThe actual call is Webgraphicscontext3dcommandbufferimpl

OpenGL ES is usually used on Android to display the rendered results on the screen, sample processing, model display, and so on. In this case, you only need to use the Glsurfaceview class and the renderer class provided in the Android API to set/write the appropriate code in the initialization, callback functions provided by these two classes. However, if you do not want the

The final display of the interface is implemented after all of these operations have been completed, so if the layout quality is poor, the time cost of each step will increase, and the final displa

Source code analysis of the View rendering mechanism in Android I haven't written a blog for almost half a year. I think my work is busy, I think there is nothing worth writing, and I think I am getting lazy, however, I recently have some new ideas about the View rendering mechanism in Android, so I want to record it

When an activity receives a focus, it is required to draw its layout. The android framework will deal with this painting process, but the activity must provide its layout level root node. Painting starts from the root node of the layout. It is required to measure and plot the layout tree. Painting is processed by traversing the layout tree and rendering the view that intersection each of the failure areas
