How can I fix it?
Are you creating the spk using the "Save SPK" option in DroidScript?
If you try to create it any other way, it will probably include .js files which the forum does not accept and it may strip them out.
Is this the only project that has been created using a rtl language? I have no experience of creating APKs with those files so do not know if that causes problems.
I have no evidence for that as I have not tested it and do not intend to install it.

In the app there are Hebrew (rtl) text but I made a lot of applications with rtl languages and I have never got an error.
You could start with the basics. Is it a native app or html?
Since it cannot create an spk it would help if you describe the directory structure and what file names make up that structure.
What is the purpose of the app?
Is it built fro scratch with DroidScript or have you included files from other sources?
Give us some idea of what the app is like and we may be able to ask specific questions.
Is that the case?
