app crashes when I add long image

I have 2 vertical arrangement (arr1,arr2) with 10 JPG images in each of them

I have 1 additional vertical arrangement with 1 long JPG image (100kb)

blocks board is empty

my apk file size: 3.5 MB

every time when I start the app it crashes "unfortunately <app name> has stopeed"

If I change image in additional vertical arrangement to another smaller image its work partially (somtimes it works and sometime crashes)

I add an attachment

How big is your AIA file?  When you say "When I start the app," does that mean in the emulator or on a device?  Please read my tips below.  Happy Holidays!

For our App Inventor Tips, visit TwoDogApps.com by clicking here!

my AIA size is 2.6MB

app starts in the device

I know that AIA size is limited to 5 MB so I dont see any reason for the crash

and I dont use blocks because I dont need them right now, I just start to build the app

note: when I remove some images from screen1 (but does not delete them from app inventor) it works good

to find out, why it force closes. you can use logcat, see also

Use SDK utilities with App Inventor by  Tony

let us know the logcat result...

I get this over and over in logcat: (I tried on the emulator)

this is your error

ANR in edu.mit.appinventor.aicompanion3 (edu.mit.appinventor.aicompanion3/.Screen1)
Reason: keyDispatchingTimedOut

see also here http://stackoverflow.com/q/5513457/1545993

you can find more information after doing a Google serch

what kind of logic are you using in your screen? any complex task?

which device do you use for your tests?

did you test after building your app with the apk file?

yes I test with apk file on my android device

there is no logic at all (blocks board is empty) I just add 22 images (screenshots) and maximum size of all of them is 2.5MB 

I get runtime error

heap size = 40903kb

allocated =24372kb

what does it means

which device do you use for your tests? most probably an older one?

do you have to display all images at the same time in your app?

probably you can reuse an image component and add some logic to your app?

Your link in your post above regarding the SDK utilities points to an expired webpage.

@Don: it seems to be, Tony's website expired, hopefully his site is up and running again soon!



my device is HTC one V4.1.1

I have 10 image components and I use each one of them to display 3 or 2 different images

but it depends on what button I press , when button is pressed former image is change to the new one (set image1.picture to ...)

do you need more info?

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

screenshot attached

what you can do is to reduce the image sizes and/or display less images the same time

I must have all images and I succeed to reduce just 200kb and its not enough 

I tried before to upload the image from website link instead to upload the image to app inventor but it takes a long time until picture is display 

(5 sec instead of 1 sec) there is a way to speed it up?
