[Azad_Verma]

I am unable to build my apk I see this Error

[Anke]

We need to see the complete error.
Post the aia.

[Azad_Verma]

BSV3.aia (1.1 MB)

[TIMAI2]

Builds OK here, tried it twice.

There was an error message when I first loaded the aia, but this did not happen on subsequent loads.

Try again ?

A lot of extensions ...

Also, an internal error loading onto the code server ...

Also, saw a loose block in the Home screen after a Cleanup Blocks:

Compiles ok on the code server:

Hello!
I noticed such a "bug" that may be related to this problem. If you create more screens, for example Screen2, and then delete that screen, the system will print this: Server error: could not delete the file. Please try again later!
Then the entire project disappears (there is an empty area). You can open the list of projects, but your last (current) project cannot be opened. Reloading (F5) the entire App Inventor helps. Then the project can be opened, you can happily build, but until you want to do a "Build".
Here is a list of the compiler error message:

App Inventor is unable to compile this project.

Try exporting the project aia file, renaming the aia file, then importing the new aia file under a different project name.

Excellent, that helped. Thank you.
