Hi Taras, I think you're right, but I find weird since I have retrotranslated all classes using the backport and target options. This is how I'm running retrotranslator now:
$ java -jar ../Retrotranslator-1.2.6-bin/retrotranslator-transformer-1.2.6.jar -srcdir srcdir -backport java.rmi.Remote:java.lang.Cloneable -target 1.5 -reflection safe -stripannot -embed . -classpath ../Retrotranslator-1.2.6-bin/retrotranslator-android-1.2.6.jar -verbose Just to double check I rebuilt my workspace and ran retrotranslator again as shown above. I don't get any errors when running retrotranslator [1] [2] but still get the same errors when running the calculator-android project. Also, I checked the sizes of the translated classes and found that they are not becoming much bigger [3] [4]. Do you think I'm missing something? Thank you so much for all your help.
