Kristian Waagan commented on DERBY-4458:
----------------------------------------

As for generating .dex files there's now http://code.google.com/p/dexmaker/=
 . Other potential libs are smali and asmdex, but no idea how well suited t=
hey are.
Anyone up for making the byte-code generation in Derby pluggable? ;)

On a similar note, but unrelated to Android, would it be better if we used =
ASM to generate the byte-code?

>          Components: Miscellaneous

> derby.jar cannot be used on mobile devices running the Android OS. Androi=
d uses Dalvik as runtime environment, and the classfiles from derby.jar can=
not be translated to Dalvik byte code.
> Steps to repeat:
> 1. get the Android SDK from http://developer.android.com
> 2. navigate to [android-sdk]/platforms/android-1.5/tools
> 3. execute ./dx --dex path/to/derby.jar
> The dx tool should convert the JRE byte code to Dalvik byte code. Instead=
, it spits out this warning several time:
> warning: Ignoring InnerClasses attribute for an anonymous inner class tha=
t doesn't come with an associated EnclosingMethod attribute. (This class wa=
s probably produced by a broken compiler.)
