It looks like these
ligne[i] = display.newText( ligne[i], 10, 10*i, native.systemFont, 24)
are not getting inserted into the scene’s view (group). Add this line just after your function call:
local function networkListener ( event )
local group = scene.view
then after your display.newText, do this:
ligne[i] = display.newText( ligne[i], 10, 10*i, native.systemFont, 24)
group:insert(ligne[i])
Then storyboard will manage those text items.
Hello rob, i did what you said, and it work, more preciasly, the text is not on all pages only in the good page so one problem resolv.
The second problem is always here! My device display 3lines instead of all the text, you can see my problem in my image : http://www.hostingpics.net/viewer.php?id=512964Screenshot20130720103807.jpg
It’s the last problem…
Are you talking about the text overlapping each other? This one is pretty simple:
for i = 1,nbr_pronos do
ligne[i] = display.newText( ligne[i], 10, _ 10*i, _ native.systemFont, 24)
ligne[i]:setTextColor(0,0,0)
end
See the 10 * i ? You are moving your text down 10px for each line. Your font size is 24, which roughly means 24 pixels high. You need to be multiplying your i variable by at least 24, perhaps more to get you more line spacing.
Maybe:
for i = 1,nbr_pronos do
ligne[i] = display.newText( ligne[i], 10, _ 36*i, _ native.systemFont, 24)
ligne[i]:setTextColor(0,0,0)
end
to give you a 1.5 line spacing…
Hi Kevin,
Please refer to the following guide under “Android Build Settings” and make sure that you configured all of the permissions properly:
http://docs.coronalabs.com/guide/distribution/buildSettings/index.html#androidsettings
Regards,
Brent Sorrentino
Thank you Brent, my permissions are good but the file txt don’t display!
i think it’s because have this error!!
[sharedmedia=core:attachments:418]
Can you copy and paste your code where you are trying to download the file and open it? Please include it in and tags (take out the space after the bracket).
Also paste in your build.settings file.
Yes :
[code]
– view2.lua
–
ligne = {}
local storyboard = require( “storyboard” )
local scene = storyboard.newScene()
local function networkListener ( event )
local path = system.pathForFile( event.response.filename, event.response.baseDirectory )
local file = io.open( path, “r” )
nbr_ligne=1
for line in file:lines() do
ligne[nbr_ligne] = tostring(line)
nbr_ligne=nbr_ligne+1
end
io.close( file )
file = nil
nbr_pronos = (nbr_ligne-1)/4
for i = 1,nbr_pronos do
ligne[i] = display.newText( ligne[i], 10, 10*i, native.systemFont, 24)
ligne[i]:setTextColor(0,0,0)
end
end
network.download(
“http://devkevin.olympe.in/pronostics.txt”,
“GET”, networkListener,“pronostics.txt”,system.TemporaryDirectory
)
[/code]
the first big bloc is a at the beginning of the view 2 and the network download after in the code when i want he appaer.
what do you want copy in build setting?
yes, please post your build.settings file. I dunno what happend with your code tags though. Looks like the closing one still has a space in it. I don’t know what the code=auto;0 is either. Though I think I see the problem.
Your networkListener is going to get called multiple times. There is an event.phase member of the event table that tells you what phase you are in. They include “began”, “ended” and potentially “progress” if you have the right settings. So when the began phase happens, you don’t have a file to open yet so your app crashes. Please add:
if event.phase == “ended” then
and
end
around your code inside of your networkListener function and see if that helps. You should also check inside that ended phase to make sure that event.isError is false. If it’s true, your connection timed out or the server was down for some reason. You should also check event.response (or maybe event.status) and look for some 200 code at the beginning (any 2XX value actually) to indicate it was successful. The event.isError can be false meaning it successfully talked to the file server, but still not find your file. If you get any 4XX or 5XX codes then it failed to retrieve the file and you should handle those conditions accordingly.
This is my build.setting file :
-- Supported values for orientation: -- portrait, portraitUpsideDown, landscapeLeft, landscapeRight settings = { orientation = { default = "portrait", supported = { "portrait", } }, android = { versionCode = "1", usesPermissions = { "android.permission.INTERNET", "android.permission.WRITE\_EXTERNAL\_STORAGE", }, }, }
and my view 2 where is the network.listener.

copy the code again, I missed a “then” after the if event.phase == “ended”…
shame on me… for the ‘then’
now i have the always same error…
we are near…
Up please its very important for me…
Can you post your current code?
I dont understand curent code …
What do you want on m’y code ?
Thanks

with the same error : http://www.hostingpics.net/viewer.php?id=639600afterdebug2.png
please
change this:
network.download( "http://devkevin.olympe.in/pronostics.txt", "GET", networkListener,"pronostics.txt",system.TemporaryDirectory )
to:
network.download( "http://devkevin.olympe.in/pronostics.txt", "GET", networkListener,"pronostics.txt",system.CachesDirectory )
and see if that makes a difference? I think your Windows isn’t letting you access the systems temporary folder. This could be a local Windows permission problem. If that doesn’t work, then try system.DocumentsDirectory
Your code will likely work on your Android device as is. I think this is a Windows problem.
Yes, your idea about Windows i think the same but i had test caches et documentsdirectory and always the same probleme no open file Stream error…
My file.txt don’t display on the screen !
