Corona test project Works at emulator but not on the Device

Question

I have this weird situation. I have 2 scenes. I can go from 1 to the other in the simulator but it crashes when I do the same on the device...

This is the code of the first scene (menu)

menu.lua

local storyboard = require( "storyboard" )
local scene = storyboard.newScene()

-- include Corona s "widget" library 
local widget = require ("widget")

-- forward declarations and other locals
local playBtn
local optsBtn
local helpBtn



-- Levels Menu
local function onPlayBtnRelease()
    -- ads.hide()
    storyboard.gotoScene( "levels", "fade", 500 )
    return true -- indicates successful touch
end

-- Options
local function onOptionsBtnRelease()
    storyboard.gotoScene( "options", "fade", 500 )
    return true -- indicates successful touch
end

-- Help
local function onHelpBtnRelease()
    storyboard.gotoScene( "help", "fade", 500 )
    return true -- indicates successful touch
end

-- NOTE: Code outside of listener functions (below) will only be executed once,

-- Called when the scene s view does not exist:

    local group = self.view
    
    -- display a background image
    local background = display.newImageRect( "background.jpg", display.contentWidth, display.contentHeight )
    background:setReferencePoint( display.TopLeftReferencePoint )
    background.x, background.y = 0, 0

    -- create/position logo/title image on upper-half of the screen
    local titleLogo = display.newImageRect( "title.png", 264, 42 )
    titleLogo:setReferencePoint( display.CenterReferencePoint )
    titleLogo.x = display.contentWidth * 0.5
    titleLogo.y = display.contentHeight / 5

    -- create a widget button (which will loads levels.lua on release)

    -- Load Configurations
    local utili = require( "utility" )

    -- all display objects must be inserted into group
    group:insert( background )
    group:insert( titleLogo )
    group:insert( playBtn )

And this is the code of the second one:

Can you help me to find what could be wrong?

levels.lua

local storyboard = require( "storyboard" )
local scene = storyboard.newScene()
-- include Corona s "widget" library 
local widget = require ("widget")
--------------------------------------------

local function onKeyEvent( event )
    if (event.keyName == "back") and (system.getInfo("platformName") == "Android") then
        storyboard.gotoScene( "menu", "fade", 500 )
        return true
    end
    return false
end

Runtime:addEventListener( "key", onKeyEvent );



-- forward declarations and other locals
local play1Btn
local play2Btn
local menuBtn

-- 'onRelease' event listener for playBtn
local function onLeve1BtnRelease()

    return true -- indicates successful touch
end

Very very Thanks. I'm new on Corona and I'm stuck on this :(

Answer 1

krs is correct!

I have disrespected the resource naming convention.

I put "-" in the name of the images files and it is not allowed.

Problem was solved changing the name of the images.
