Typical drawing process for 1.1.1 applications We know that Bufferqueue has up to 32 bufferslot, so what is the purpose of this design? One possible reason is to improve graphics rendering speed. Because if there are only two buffers, imagine that when the output efficiency of the application producer is greater than the processing speed of the consumer, it will soon dequeue the buffer and be in the waiting state, causing unnecessary trouble. Of cour

Android obtains desktop applications and android obtains desktops. First, before reading this blog, you can look at this blog, http://blog.csdn.net/harryweasley/article/details/50057707 This section describes two methods to obtain application information: packageInfo and ResolveInfo. A bug occurs when packageInfo is used to obtain application information, that is

Each variant of the name, like Friendlydebug, is capitalized (Friendlydebug), and then the corresponding installation task (INSTALLFRIENDLYDEBUG) is added to the installdebugflavors task.This mission is in the configuration phas

Android provides a rich set of UI components, all of which are inherited from the view class , and the view component is very similar to the swing programming JPanel, which represents a blank rectangular area. Android uses the "combo" design pattern to Design view and ViewGroup:ViewGroup is a subclass of view, so viewgroup can also be used as a view . Instead of using Java code to develop the user in

The Dalvik Virtual Machine supports garbage collection, but this does not mean you don't have to worry about memory management. Pay special attention to the memory usage of mobile devices. The memory space on the mobile devices is limited. In this article, let's take a look at how some of the memory profiling tools in the android SDK help us trim the memory usage of the application. Some memory usage problems are obvious. For example, if the app has a
