It is believed that most people start with a white or black screen before starting the app and then entering the first interface, for example: Splashactivity. Then what is the cause of it? The reason is that we have to change the theme of activity/application set cause, because the theme of the corresponding Windowbackground and other backgrounds are set to white or black, And when we enter the first interface of the

in memory optimization, we found that in addition to resolving memory leaks, the only thing left was to reduce the actual memory footprint. In the app, most of the memory may be occupied by our pictures, so reduce the memory footprint of the image can bring a direct effect. This article simply introduces how much memory a picture occupies, let's assume that we have a p
