Libgdx Game Crashes on Android Phone

Question

I have created a sample game that runs perfectly on desktop but crashes with following error on android phone.

**Unfortunately, My LibGDX Game has stopped.**

I have tested with two different phones and even the emulator but the error remains the same. Below are the project properties for Android version.

LogCat is(With Error Filter):

Answer 1

Thanks everybody:) Issue is solved. Actually the file name was

"smountains.PNG"

and in main libgdx project I was using the syntax with

sMountainTexture=new Texture(Gdx.files.internal("images/smountains.png"));

The difference in case "png" and "PNG" didn't matter in case of Desktop Project but was taken as error in Android Version. Thanks every body again for help.
