images not working

Hi people, i have been making my ai2 project and am having some very annoying issues. i have made an app with button and am using .png images for the buttons. after i build the app and install it on the phone some of the images do not show up also not showing up in the ai2 creation window, if i then rebuild the .apk and install it again the same thing happens but with other images, sometimes 2 or 3 and sometimes up to 4 or 5 images don't show, always different ones each time. this also happens with the .jpeg background image.

i have checked another app i made a while ago that previously had no problems and the same thing has happened to that one too.

WHAT IS GOING ON???

is app inventor just broken?

i mean the app i have just made is a very simple application for opening 3 other screens with info on them and 9 buttons to open web pages, simple right? please please help me, i'm going mad with this and i need to get this app made and working for a friend of mine.

Did you read the information liked from the RED box in the AI Splash Screen?  Obviously not... just glanced over that box and continued.

Please reload the tab and click on the link in the hard-to-miss red box there on the splash screen.

Honestly, we don't post stuff there just for the heck of it, and we expect our users to pay attention and read the screens.  Perhaps that's asking too much, huh?

Anyway, do that and you'll have your answer...

Red Box??? Where? I've posted this where everyone else has posted questions with problems???

Jon... In the Splash Screen that opens up when you go to the App Inventor site, not the forum, there's a BIG RED BOX...  You have to click the continue button on the Splash Screen to get to the AI project screen, so the RED Box is right there in front of you before you go on.  Anyway, here's the page it links to:

Thanks, true I didn't read that, I can breath a sigh of relief now that I know it wasn't something I was doing wrong. Perhaps I should have read that but as most people do just click off the splash screens. Thanks for your help enis and I will make sure I read splash screens from now on. :)

NP Jon... and I've asked them to make that message there more generic so it applies to anyone with an operational problem!

The easiest way to check what's happening is to make an AIA file, change the extension from aia to zip and open it.  Check the assets there and I'm sure you'll see some that are 0 bytes... (don't forget to rename the zip file back to AIA or just nuke it and recreate a new one).

MIT App Inventor still has issues with the Google Cloud Storage, as mentioned in the red splash screen which results in missing assets, see also here https://docs.google.com/document/d/1wQy_1uCsZDAXY51wElbMyfy8AJid_EOqklIX_ggzBJY/pub

What you can do meanwhile is 

1. wait until these issues are fixed, or

2. install a personal server and work completely offline. 

Krupong just updated AI2U, version 2.3 is now identical to the MIT App Inventor version nb139c as of Dec 13. Just download the 32 or 64 bit version here http://sourceforge.net/projects/ai2u/files/ai2u%202.3/, install it, start AI2U and your own personal server is up and running! Then just open your browser using the address http://localhost:8888 . That's all.

And btw. with your own personal server you also will be able to build projects larger than 5 MB. So what are you waiting for?

This was also driving me nuts.  I was just scratching my head looking over my code over and over.  Glad to know I am not crazy!
