BitmapTextureAtlasTextureRegionFactory.createFromAsset crash

i have took a look to andengine a few months ago, and i managed to make something out of it. Now i downloaded the newest version, and i'm having a crash for the simplest thing. Here my code

package francesco.mygame;

The logCat error is

Failed loading Bitmap in AssetBitMapTextureAtlasSource. Asset path: gfx/play.png

java.io.FileNoFoundException: gfx/play.png

But i put the 2 images i开发者_运维百科n the folder and i added them to the project like i did when i first tried andengine(and it worked).. So i don't really understand where the problem is..

The images are 2 png created with the gimp(one is 57x36 and the other 58x31).

A java.io.FileNoFoundException will be thrown if a file wasn't found - so there is no other possibility than the engine couldn't found the image.

Make sure your images are in: assets/gfx/ and not just in a folder called gfx/.

Make sure there is assets folder in your project and from BuildPath options(project options-you can access by right-click on your project explorer), from Source Tab press Add Folder button and check assets folder to import your compilation process.

gfxfolder must be in assets folder. If there is no such folder and all your images is assets folder, you don't have to set BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/")

I am new to android and if I gain errors I try possibilities rapidly to find correct one.
