How big is your image?

It may not have enough memory allocated depending on how you setup or what your environment is. Or it could be a loop or anything...paste your code from where it's happening

i just realize that is the image that was too big, i tries added a smaller image and it worked. But does that mean that i cant send a good image or just a bad quality ones

What's it for? And how big was your image?

You should be able to get pretty good resolution images loading with no issues...

it was 2.6 MB

Mate that's huge!

If you have Photo Shop save it out as a JPEG and reduce the size of it. Most images that size have massive px heights and widths so resize to what it's going to be displayed at. If you're displaying at 300px by 300px make sure the image isn't 2000px by 2000px..this would give you an Out of Memory Exception in some cases :)

And if it needs an extra bit of love once it's resized (which it shouldnt) you can optimize it here: https://kraken.io/web-interface

If your image has to be super high res then there is a config in Android that allows you to set how much memory is allocated. However I'd recommend against this as it give poor perfromance

Ok now I get it, but my question is how apps like Whatsapp can send and retrieve an image that big?

I don't think they do, I think they compress it for display purposes

OR

If they do they use streaming through sockets instead of brute loading

Google around for "image stream to byte array" or something like that, I haven't done pure Android in ages, been doing Cordova lately

ok ok thanks man!!! know I understand!!!! God Bless you man!!
