folder in your project.Then you need to put the name of your package, which is what is changed in note One, and is the same as the package name of the Android project.Failure to do so will result in the packaging not being successful, or the application failing to install, or applying a flashback.But want to sharesdk such plug-ins, they are no mainactivity, so it does not involve the uniform problem of package name.So here, all my sharing is over, writing relatively humble, I hope you like.
The go language package is very similar to the package in Java, both in the way the code is organized and in relation to the directory structure on disk.In the go language, the package name is generally the directory name of the go code, but unlike Java, the package name is only one level in the go language, while in J
There are already various language packs on the installation disk and we just need to find them and install them.

Golang has been used for some time, the Go's co-process and GC garbage collection features do improve program development efficiency. But after all, it's a new language, and if it's not understood, it might be used to pop a variety of Pandora's boxes. Let's talk about the use of the pool class of the Sync pack I used in my project to avoid confusion.

Package Bufio implements buffered I/O. It wraps an IO. Reader or IO. Writer object, creating another object (Reader or Writer) that also implements the interface but provides buffering and so Me help for textual I/O.

Install the Go Language Pack in Ubuntu Linux.
1. Download go linux development kit
2. decompress the package to the directory.
3. Set Environment Variables
Export GOROOT = xxxx/goExport GOOS = linuxExport GOARCH = 386
#(386 indicates that 32 is linux, and 686 indicates 64-bit linux. You can use uname-a to view it)Export PATH = $ PATH: $ GOROOT/bin
4. Run

switches to the Pyinstaller folder and executes commands such as:
Pyinstaller myscript.py
Of course, you can also add output options to get a better exe executable file, such as:
Python pyinstaller.py--upx-dir-f xxx.py
-F is used to create a standalone executable program,--upx-dir for compressing files.Attention:

If Upx.exe has been copied to the Pyinstaller folder, UPX is used by default, and if
Go is a feature that is automatically recycled with memory, so memory is generally not compromised. However, there is a leak in the goroutine, and the leaked goroutine reference memory cannot be recycled.In the following program, the background goroutine enters the natural number sequence to the pipeline, and the output sequence is in the main function. But when break jumps out of the for loop, the background goroutine is in a state that cannot be rec
