[Facebook] Login and Loading Spinning

Hi there
It’s my first time trying to use facebook and corona together, and I’m having a simple “problem” (it’s not a logical or code problem, its more visual). When my app tries to login facebook a black screen opens twice with a spinning circle (on android). I want to trade this for one of my loadings, I tried to do something like this to solve the problem:

local function onSystemEvent ( event ) &nbsp;&nbsp; &nbsp;if event.type == "applicationSuspend" then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--its logging on facebook &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;bigLogo&nbsp; = display.newImage("bigLogoLetsParty.png", systemDocumentsDirectory) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;bigLogo.x = display.contentCenterX &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;bigLogo.y = display.contentCenterY &nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;if event.type == "applicationResume" then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;bigLogo:removeSelf() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;bigLogo = nil &nbsp;&nbsp; &nbsp;end end

But it just failed.

Here’s the another part of the code:

local composer = require "composer" local json = require( "json" ) local fieldRequested = "me/events/created" display.setDefault("background", 255, 255, 255, 1) local function facebookListener( event ) &nbsp;&nbsp;&nbsp; print( "event.name", event.name )&nbsp; --"fbconnect" &nbsp;&nbsp;&nbsp; print( "event.type:", event.type ) --type is either "session", "request", or "dialog" &nbsp;&nbsp;&nbsp; print( "isError: " .. tostring( event.isError ) ) &nbsp;&nbsp;&nbsp; print( "didComplete: " .. tostring( event.didComplete ) ) &nbsp;&nbsp;&nbsp; --"session" events cover various login/logout events &nbsp;&nbsp;&nbsp; --"request" events handle calls to various Graph API calls &nbsp;&nbsp;&nbsp; --"dialog" events are standard popup boxes that can be displayed &nbsp;&nbsp;&nbsp; if ( "session" == event.type ) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; --options are: "login", "loginFailed", "loginCancelled", or "logout" &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if ( "login" == event.phase ) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; local access\_token = event.token &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; --code for tasks following a successful login &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp; elseif ( "request" == event.type ) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; --print("facebook request") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if ( not event.isError ) then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--process response data here &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if(event.response == nil) then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("response nil") &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;else &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("fieldRequested: ") &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print(fieldRequested) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local response = json.decode( event.response ) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("response decoded = ") &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if (fieldRequested == "me/events/created") then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;for i,v in ipairs(response.data) do &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--print(response.data[n].name) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print(v.name) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp; elseif ( "dialog" == event.type ) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print( "dialog", event.response ) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; --handle dialog results here &nbsp;&nbsp;&nbsp; end end local fbAppID = "XXXXXXXXXXXXXXXX"; -- id do aplicativo / appID facebook.login(fbAppID, facebookListener, {"user\_friends","user\_events","publish\_actions"} ) --Id, listener e permissoes / Id, listener and permissions
