Server error: Could not save one or more files, try again later!

[Irene Agustin]

Hello, I've been working with App Inventor and it has been working fine for some months. Today I've tried to build my app but it says "Server error: Could not save one or more files, try again later!". I have developed some other projects but I recive the same error mesage for all of them. How can I fix it?

Did you get this working Irene?  

Sometimes the solution is to   try again later .    If not you could be getting the message for a variety of reasons, the most common being:

One of the following  possibly applies to your code (all may not apply to your code):

1)  You have coding errors in your blocks.  In the Blocks editor, look in the lower 

left corner of the window for the yellow and red triangle icons. If the red icon has a value larger than 0, 

you have a serious coding error.  Find the block in your code that has a red triangle and 

fix it.   Red triangles always inhibit creating an apk or running a project in the 

emulator or possibly creating an aia file.     Yellow triangles are more forgiving, 

however, sometimes, these need to be fixed because they trip an internal warning and not filling puzzle piece sockets that are left un-filled can sometimes cause issues if the app needs a value that is not filled.

2) Your source file (the aia file) is larger than the 5Mb limit allowed in AI2 (the aia can not be larger than 5Mb). You may have put images or other resources in your Media (resources) that you do not use in the app.  All the images and sounds in resources count toward the 5Mb limit along with the source code.    You can program apps larger than 5Mb in the browser, but the apps will not compile and might not run in the emulator or the project may not save as an aia. If this is the case you need to reduce the size of your image and/or sound files.   Most image files can be made quite small by resizing them using a photo manipulation program on your PC to less than 50Kb each.

3)  You might have more than 10 Screens in your app.  AI2 becomes unstable when more than ten screens are used.  Projects CAN be built with slightly more screen but then you should expect your app to occasionally behave erratically.

Anything familiar?
