Android Studio Setup Project module encoding to solve garbled problems when executing Android studio projects

The project setup logic for Android studio differs greatly from Eclipse. Run the operation for File->setting->file encodings and then come to the settings that you see:

Watermark/2/text/ahr0cdovl2jsb2cuy3nkbi5uzxqv/font/5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/dissolve/70/gravity /center "width=" "height=" >

Opening the module's Build.gradle file changes the encoding used by the compiler, which, through the above settings, can only affect the encoding of the contents of the file you see in the editor view inside the IDE.

The encoding used by the compiler also needs to be set separately, otherwise the Gradle default use Utf-8 encoding and the actual encoding of the file is inconsistent, it will cause the program to display garbled when the execution.
The Gradle configuration code is configured in the Build.gradle script file. Add the following configuration.

Android {... compileoptions {encoding "GBK"}}

If you just set a file's encoding, open the file directly in Android Studio. The file encoding option appears when you right-click.
