But think about i

This article shows you how to use the Chronometer control to implement an instance of an Android timer. Put the final implementation diagram first: The idea of Android timer implementation Use the chronometer control to implement the action of the meter. Set the initial time by setting SetBase (long base) and add

Let's start with the idea that we have a picture-cutting application in the Android system, so we just need to pass the photos we got to the picture-cutting application and then return the clipped photos to our own screen. In the process of developing some apps, we may be involved in the processing of avatars, such as from the phone or photo albums to get the Avatar, tailored to their own needs of the avatar, set or upload avatar. Some of the relevan

This article illustrates the Android triangle on Glsurfaceview based on OpenGL and the use of projection and camera view methods. Share to everyone for your reference, specific as follows: Defining triangles OpenGL allows us to use three-dimensional coordinates to define an object. Before we draw a triangle, we need to define the coordinates of its various points. We typically use arrays to store the coor

Android uses the binder mechanism to implement IPC, Binder communication is achieved with the help of Linux binder driver, two interprocess IPC feel like a process to enter another process to execute code, and locally can return the result of the remote function. Binder user space maintains an available thread pool for each process, the thread pool is used to process incoming call requests, including the requested message, and the remote response mess
