"aapt package" Command - Resource Code Generation
This section describes the 'aapt package' command to perform the resource code generation step in the Android project build process. The main output is the R.java file in the .\gen folder.
Looking at the output of "ant -verbose debug", I have created this "aapt package" command to perform the resource code generation step of the build process. This is how the command works on the HelloAndroid project:
C:\herong\HelloAndroid> \local\android-sdk-windows\build-tools\22.0.1\aapt package -v -f -m -M AndroidManifest.xml -S .\bin\res -S .\res -I C:\local\android-sdk-windows\platforms\android-22\android.jar -J .\gen --generate-dependencies Configurations: (default) hdpi ldpi mdpi Files: drawable\ic_launcher.png Src: (hdpi) .\res\drawable-hdpi\ic_launcher.png Src: (ldpi) .\res\drawable-ldpi\ic_launcher.png Src: (mdpi) .\res\drawable-mdpi\ic_launcher.png layout\main.xml Src: () .\res\layout\main.xml values\strings.xml Src: () .\res\values\strings.xml AndroidManifest.xml Src: () AndroidManifest.xml Resource Dirs: Type drawable drawable\ic_launcher.png Src: (hdpi) .\res\drawable-hdpi\ic_launcher.png Src: (ldpi) .\res\drawable-ldpi\ic_launcher.png Src: (mdpi) .\res\drawable-mdpi\ic_launcher.png Type layout layout\main.xml Src: () .\res\layout\main.xml Type values values\strings.xml Src: () .\res\values\strings.xml Including resources from package: \ C:\local\android-sdk-windows\platforms\android-15\android.jar applyFileOverlay for drawable trying overlaySet Key=ic_launcher.png baseFile 0 has flavor ,,,,,,,,,,,hdpi,,,,,,, baseFile 1 has flavor ,,,,,,,,,,,ldpi,,,,,,, baseFile 2 has flavor ,,,,,,,,,,,mdpi,,,,,,, overlayFile 0 has flavor ,,,,,,,,,,,hdpi,,,,,,, overlayFile 1 has flavor ,,,,,,,,,,,ldpi,,,,,,, overlayFile 2 has flavor ,,,,,,,,,,,mdpi,,,,,,, found a match (0) for overlay file ic_launcher.png, \ for flavor ,,,,,,,,,,,hdpi,,,,,,, found a match (1) for overlay file ic_launcher.png, \ for flavor ,,,,,,,,,,,ldpi,,,,,,, found a match (2) for overlay file ic_launcher.png, \ for flavor ,,,,,,,,,,,mdpi,,,,,,, applyFileOverlay for layout applyFileOverlay for anim applyFileOverlay for animator applyFileOverlay for interpolator applyFileOverlay for xml applyFileOverlay for raw applyFileOverlay for color applyFileOverlay for menu applyFileOverlay for mipmap (new resource id ic_launcher from \ .\bin\res\drawable-hdpi\ic_launcher.png) (new resource id ic_launcher from \ .\bin\res\drawable-ldpi\ic_launcher.png) (new resource id ic_launcher from \ .\bin\res\drawable-mdpi\ic_launcher.png) (new resource id main from .\res\layout\main.xml) Writing symbols for class R.
I think my "aapt" package command is working. The main output is the .\gen\com\herongyang\R.java file. What do you think?
