Hi, did U copy the icon from the demo in your assets folder?

or put some icon in your assets folder and call them by:

SetImageForEmptyUri and SetImageOnFail

JakeBullet70 · Sep 20, 2014

I am getting the same error above and yes, the icon is there.
How do I call 'SetImageOnFail' ?

Hi, store some Icon in your assets folder = your Project and in your project there is a File( Files = assets folder)
and in Activity_Create call example:

vp.SetImageForEmptyUri = "icon.png"
vp.SetImageOnFail = "icon.png"

Thanks. I just had to do it before I called init.

Hi Lonleystar, is there any way to increase the image quality of the displayed images even if it slows down the paging between items. I am displaying photos with text that has been overlay onto the original photo and you can tell the image quality is quite low as the text is blurred. Thanks ...

Parsing code. 0.00 Compiling code. Error Error compiling program. Error description: Riferimento a un oggetto non impostato su un'istanza di oggetto. Occurred on line: 36 vp.ToggleFade = True Word: =

if i comment this line all work. Any idea ??
Thank you

Hey @MarcoRome,
Just simply write vp.ToggleFade (with no = true/false) if you want the fade transition effect to be enable. If you don't write that code it will be by default disabled.

I like it a lot but my feeling says the diskcache does not work. When I go offline I cannot load images which indicates the cache does not work. Where do you exactly store cache images?

Would be nice to set a cache directory or db.

Cheers.

Seems the cache is indeed working. Can I switch off error messages or intercept them?

Hi, U don't need to switch of by default CacheOnDisk and CacheInMemory are off

The cache stuff works but how can I supress error messages like output error, cannot decode image etc.
