(4 bytes is a well-performing value) so that the Android system can read the file using the Mmap () function (see the purpose of the function itself) to get higher performance on read resources ,Ps:1. Alignment on a 4-byte boundary means that, in general, the compiler bar 4 bytes are read as a unit, so that the CPU can access the variable efficiently and quickly (not before).2. The root cause of alignment: The Davlik virtual machine in the

I am guilty. I spent an afternoon and finally learned from myself without a teacher. I used C # To develop my first Android browser app. I am sorry for the Java Community (with the development process)

How to write an Android APP in PythonWriting Android apps using Python is definitely not the best choice, but it must be a very lazy choice and I really don't want to learn Java. Furthermore, as far as programming is concerned, there will already be Python and Golang (Note: Python and Golang are both at the normal level). After a long time,

more perfectly.One thing to be aware of is that Coordinatorlayout does not know the internal workings of Floatingactionbutton or appbarlayout, It simply provides an additional API in the form of Coordinator.behavior, which enables child view to better control touch events and gestures, and to declare dependencies between them, and receive callbacks through Ondependentviewchanged ().You can use Coordinatorlayout.defaultbehavior (your View.Behavior.class) annotation or use app:layout_behavior= in
