But my down-loaded-app's image is "MIT APP Inventor image" on my cell phone

I made icon image of my app and registed in Google play store.

But my down-loaded-app's image is "MIT APP Inventor image" on my cell phone.

Your image image

How can I change from your image to my image on the phone?

Did you enter the filename of your iconfile here? See icon. Now it says None....
image

Iconfile is empty.

So I upload my designed Icon.

I will test it in google play store. Thanks....
