Does this tool work for anyone? If so, please let me know what version of eclipse you are using.

I'm using the latest versions of eclipse (64bit) on windows 7 with the latest ADT eclipse plugin.

Answer 1

You can not belive this. I have exactly the same problem and is because I comment a class entirely. So I think that when eclipse try to change the package name of a commented class it throw this error.

To solve the problem you only has to delete the class or uncomment it.

Answer 2

I was facing the same problem. I just was was not able to rename the package using package > right click > rename package. It appeared the package references in some xml templates, using custom controls were not updated, so the R file could not be generated. After looking at the xml and renaming the references, the R file was generated and I could continue renaming.

Answer 3

Actually I decided to create my own package rename tool.

It's very simple in fact:

• Replace the AndroidManifest.xml with the [packagename].
• Replace [packagename].R in all *.java files
• Replace SCHEMAS in xml files: http://schemas.android.com/apk/res/[packagename]

I then choose to 'not update launch configurations' and refresh eclipse project.

All goes well then :).

That combined with git branches and the antenna preprocessor helps me to get the flexibility I need to perform many versions of an application with various options.
