It worked!!! Here is what I did thanks for your advice:
- Downloaded the aia file.
- Changed its extension to “zip”.
- Extracted the files and folders in the zip file.
- Opened in text editor the files: “\src\io\kodular\ramidagan\MiHuZe\Screen1.scm” and “\youngandroidproject\project.properties”.
- Changed the occurrences of the old name “WhatsaPooh” to be the new name “MiHuZe”.
- Compressed the files\folder as an aia file.
- Imported the edited aia file to Kodular as a new project.
Now I am able to download the apk, install it and the app is running as expected. Thank you all (@dora_paz , @S.Vishwaja , @Boban ) so much for your great help. Its great to know I can keep in mind I am not alone when I have unexplained issues.
