Hi Taras, Thanks for your help. I think your suggestions resolved the problem, even though I'm getting other errors now. By mistake I sent the email only to you which I think resulted in me being the only recipient of your response. I include your response and my follow-up below, as someone else might find this useful.
Unfortunately I cannot open the TUSCANY wiki at the moment but it looks like > the contents of retrotranslator-android-1.2.6.jar hasn't been included > into the dex file. Try to explicitly refer to it in your code, for instance, > call > net.sf.retrotranslator.android.main.java.lang._Class.cast(String.class, > "test"); > > And you needn't use the 1.4 target - only using the 1.5 one makes sense for > Android. > I forgot to mention that you can use the embed option making inclusion > of retrotranslator-android-1.2.6.jar into the compile path redundant. > > So you can add "-embed <a single dot or any package name>": > > java -jar > ../Retrotranslator-1.2.6-bin/retrotranslator-transformer-1.2.6.jar > -srcdir ../workspace -target 1.5 -reflection safe -stripannot -embed . > -classpath ../Retrotranslator-1.2.6-bin/retrotranslator-android-1.2.6.jar > -verbose > After following your suggestion and adding retrotranslator-android-1.2.6.jar as an external library (as opposed to an external _user_ library) the retrotranslator related errors disappeared. I'm now receiving errors about java.rmi.Remote [1], which from what I could find is not supported in Android. I just thought I'd mention it in case you have any suggestions :-) On Tue, Jun 17, 2008 at 8:16 PM, Oscar Castaneda < [EMAIL PROTECTED]> wrote: > Hi Taras, > > Thank you so much for the detailed response. > > I think you're right that when I run the Android project from Eclipse it > both compiles the sources into classes and the classes into a dex file.
