Determines whether a view object is accelerated by hardware.
Sometimes, especially for custom view objects, It is very helpful for applications to know whether the current view object is accelerated by hardware. This judgment is particularly useful if the applicat

First, my idea:There is no wheel in the world, just the code of the number of people, there is a wheel! Because so far we have not developed a fully self-learning code code, while the requirements are constantly moving toward the direction of complexity, so the code has become more and more thin division of labor! Once hardware and software This is a, code code will have to follow the hardware platform, thr
Drawing operations not supported by hardware acceleration
During hardware acceleration, the 2D rendering pipeline supports most of the drawing operations that are usually used for canvas and some rarely used operations. Used for rendering applicationsProgramAll of the drawing operations are sent to the Android system, the default widgets and layout, and some common visual effects, such as reflection and t

For example, download the 1.2.0.5 library from codeplex of 51degrees.mobi.
Why download the version 1.2.0.5 is simple. Because the library of version 1 implements the wurfl interface and uses the wurfl hardware package, you can accurately obtain the hardware model. The Library of version 2 can no longer obtain the hardware model. Only the paid version can be use
