Android Ant Build.xml Instance

Use ant to compile apk. You only need to modify the SKD path Javahome path and project path when using it.

Call Dx.bat to the third-party library file that the. class file and other calls to Compiling into a. dex file (. dex files can be run directly on the Dalvik virtual machine file format, can be understood as the Java bytecode for embedded device optimization) 6.
