    Error running exported APK

    in General questions
    Hello!

    I tried to test my exported apk, trying full export, but I am facing a weird thing: It is crashing... Strange.. because in the export as player I never faced trouble and I thought that'd be the same... Then I tried to open in the android studio to debug and I am having a weird error that I have no any idea why it is happening...
    E/AndroidRuntime: FATAL EXCEPTION: GLThread 1104
                  Process: app.paulo.game, PID: 8961
                  com.giderosmobile.android.player.LuaException: Helper/TiledMap.lua:20: attempt to call a nil value
    My lua file that is pointing the error is the following:
    local map = loadfile(filename)()

    does anyone have a light? because in the player i don't have any compilation error pointing "nil" value but why now after apk full exported it is trowing this?

      Is it crashing on the start?

      It is a good practice to make essential variables safe after we load them, like:
      coinsTotal = dataSaver.loadValue("coinsTotal")
if coinsTotal==nil then
    coinsTotal=0
end
      Maybe you could find what variable is nil, and make it safe to work with.
      (I'm not sure if it helps, I'm also newbie in debugging)

      In your case you can write:
      local map = loadfile(filename)()
if map==nil then
map=yourSafeValue
end

      Maybe you forgot to ‘exclude from compilation’ the file you are trying to load dynamically ?

      @hgy29 Do you mean "exclude from execution"?
      I tried to do that and then export it again but nothing... same thing.

      @Apollo14 I don't know what 'safe value' I could set to a variable... it is a tiledMap configuration. I load a map in it.

      Yes, in the app launch It stops

      This is better...
      coinsTotal = dataSaver.loadValue("coinsTotal") or 0
      and
      local map = loadfile(filename)() or yourSafeValue

      @SinisterSoft thank you for the answer, but I load a map in the tiledmap. I don't know what 'safe value' I could set. Can I declare inside a loop while not nil? Don't know

      Maybe you should check your filename. Gideros player doesn't care about case errors in filenames.. but on export.. the device DOES care about case errors with filenames. This is one of the most annoying things I find in Gideros :D

      @antix I thought EXACTLY on that. Then I changed the names of my png files that the tiledmap calls, one is for "clouds.png", the other for "groud_small.png". But it still keeps throwing me the error. Is anything wrong? I mean it does accept "_"... and in my folders there is no "_" in any folder names just unique name.

      I set the file "Exclude from execution" now it works @antix @hgy29

      It compiled successfully on android studio :smiley:

      Aside from this, why do you still use Android Studio rather than the built-in apk creation?

      If you map loader results in a table being returned then just provide the table as the other answer,
      local map = loadfile(filename)() or {} -- in the table here put 'default' map data

      @SinisterSoft I tried but App Crashed... Then I imported it to android studio to debug and figure out why it was going on. But the tip of @hgy29 worked for me to "exclude from execution" the lua file containing map informations. Don't know why but it worked :smiley:

      by the way, now every change I make in gideros I'm exporting as "assets only" and debuging on android studio, this is working perfectly
