"dx.bat --dex" Command - Converting .class Files into .dex File
This section describes the 'dx.bat --dex' command that can be used to convert Java byte code (.class) files into a Dalvik executable (.dex) file.
The next tool used in the "ant -verbose debug" command is the "dex" tool, which converts Java byte code into a .dex (Dalvik Executable) file.
Looking at the output of "ant -verbose debug", I have created this "dx.bat --dex" command to perform the byte code conversion step of the build process. The dx.bat calls a Java application to do the actual conversion work. This is how the command works on the HelloAndroid project:
C:\herong\HelloAndroid> \local\android-sdk-windows\build-tools\22.0.1\dx.bat --dex --verbose --output .\bin\classes.dex .\bin\classes processing ...\bin\classes\com\herongyang\BuildConfig.class... processing ...\bin\classes\com\herongyang\HelloAndroid.class... processing ...\bin\classes\com\herongyang\R$attr.class... processing ...\bin\classes\com\herongyang\R$drawable.class... processing ...\bin\classes\com\herongyang\R$layout.class... processing ...\bin\classes\com\herongyang\R$string.class... processing ...\bin\classes\com\herongyang\R.class... C:\herong>dir \herong\HelloAndroid\bin\classes.dex 2,328 classes.dex
I think the command worked correctly. All *.class files are converted into a single .dex file: classes.dex.
