Android Question B4Agalleryview 3.10 and OutOfMemoryError

[kostefar]

Dear All,

I modified the example in https://www.b4x.com/android/forum/threads/library-b4agallery-v3-55.24963/#content a bit:

    Gallery.Initialize("Gallery")
    Activity.AddView(Gallery, 0, 105dip, 100%x, 100%y)
   
    'Gallery.CreateCache = "Pippo.Pluto.Paperino"

    Gallery.TextSize = 16
    Gallery.TextColor = Colors.Yellow
    Gallery.ShowText = False
    Gallery.ItemWidth = 140
    Gallery.ItemHeight = 140
    Gallery.Spacing = 10
   
    '*************************************
   
    'Gallery.ScaleType = Gallery.ScaleType.Center_Crop
    Gallery.ScaleType = Gallery.ScaleType.Center_Crop
    Gallery.SetNoEffect = True
    Gallery.SetBorderColor=Colors.Yellow
    Gallery.SetCornerRadius = 0
    Gallery.SetBorderWidth = 0
    Gallery.SetOval = False
   
    '*************************************

    Gallery.ShowFromMediaStore

And it did what I wanted. Then I tried moving it to the code for the app I´m working on, but got:

java.lang.OutOfMemoryError: OutOfMemoryError thrown while trying to throw OutOfMemoryError; no stack trace available
java.lang.OutOfMemoryError: Failed to allocate a 12 byte allocation with 3424 free bytes and 3KB until OOM

I tried copying my manifest over to the example app, in order to find out if something there could have any impact, but that one was still running fine.
Then I tried doing so that loading the gallery would be the very first thing happening in my own app, and nothing else would happen after that - just to see if something happening in the app would take up alot of space, but still the same.
Then I tried with

SetApplicationAttribute(android:largeHeap, "true")

in the manifest, still no luck.
I then tried increasing the memory in the genymotion emulator from 2048 to 3172 - same result.
Then I found out that if removing gallery.showfrommediastore, things are working. Obviously this one is crucial, but maybe it gives a hint of what is going on? There are only some 15 pics in the mediastore of the device.
The reason that I´m not using the 3.55 version of the lib is that if I do so, some properties of the library from v3.10 are no longer recognized.

The app I´m working on is pretty large, and there´s a lot of things that I want to remove from it, but I doubt this would be of any help since the problem occurs even before the app has done anything else than just loaded.

Does anybody have any ideas about what´s going on here?

Thanks in advance!

Maybe your pics are to big.
Try it with some realy small pics and see if it works.

Thanks, so I just tried this.. moved all photos, which were indeed large but worked fine with the example, to another folder. Put an image that´s only 300x300 pixels and 50 kb there. Same problem.
Only if the folder is empty I don´t get the outofmemory error...

Try the new beta 3.7 - there is a new feature exactly for this situation: LoadBitmapResize. Search in the forum, it could be the feature you need in this situation!

Thanks rboeck, but I cannot find this anywhere. Are you sure it´s not photopager, of which there´s a v 3.8?

Sorry, my mistake, i wanted write 7.3 instead of 3.7 - here is the link to the info:https://www.b4x.com/android/forum/t...dbitmapresize-loadbitmapsample.82693/#content
and the beta: https://www.b4x.com/android/forum/threads/b4a-v7-30-beta-is-available-for-download.82665/#content

Ahh yes, already installed that one! That could indeed be a great improvement in this situation, but it would need the library to be updated.

Update: Decided to go with https://www.b4x.com/android/forum/threads/lib-class-customgallery.20082/ instead. No memory errors there!

And yet another update. Maybe I missed it, but the above does not have loadimageasync which makes it too slow for what I wanted to achieve.
Hence, I fiddled and fiddled with UltimateListView and came up with a lovely horizontal gallery scroll view, loading images at the speed of light!
Can´t emphasize enough how amazing ULV is, and really worth spending time to understand.
