Android app UI hardware accelerated rendering technology brief introduction and Learning Plan

The fluency of the Android system has been compared to iOS and is considered inferior to the latter. This aspect is related to the uneven quality of the Android device, on the other hand, and the implementation of the Android system. For example, before 3.0, the Android application UI drawing does not support hardware acceleration. However, starting from 4.0, the Android system has been optimized for the UI with "run fast, smooth, and responsively". T

Overview and learning plan of hardware accelerated rendering technology for Android application UI

Overview and learning plan of hardware accelerated rendering technology for Android application UI The smoothness of the Android system has always been compared with that of iOS, and is considered inferior to that of the latter. This is related to the hardware quality of Android devices and the implementation of Android systems. For example, Android app UI rendering before 3.0 does not support

GPU hardware acceleration control in Android and its limitations on 2D graphics rendering

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 programs (OpenGL, DirectX) are GPU-accelerated.Before Android3.0, the 2D drawing API only supported software rendering mode, starting with A

Learning to identify computer hardware faults

The poorest people in the computer market are counting the people who have moved faulty computers. Although the Assembly Machine has her strengths compared with the brand machine, it is her critical weakness to have no good after-sales service. Most computer faults are software faults, so there is no need to migrate the entire machine before it is determined to be a hardware fault. Even if the hardware is

Android Hardware acceleration

OverviewStarting with Android 3.0 (API L11), Android is starting to use hardware acceleration for 2D rendering, hardware acceleration means that graphics images drawn on the view in Android are drawn using the GPU, using hardware acceleration and, most of the time, making the drawing smoother, But the cost of paying is to consume more memory resources.Hardware ac
