Display image from remote location

Solar2D Native builds

Hi good evening,

 

I’m trying to load a remote image via “display.loadRemoteImage”, it only works on simulator, it doesn’t work mobile phone. Is there a setup I need to do to make it work I already enable the write external strorage and internet permision.

 

local function networkListener( event )

        if ( event.isError ) then

                print ( “Network error - download failed” )

        else

               anchor(event.target)

               event.target.x = 0

               event.target.y = 0

        end

end

local img_map = display.loadRemoteImage( “http://maps.googleapis.com/maps/api/staticmap?center=13.6217, 123.21781&zoom=16&size=120x100”, “GET”, networkListener, “map_thumbnail.png”, system.DocumentsDirectory, 0, 0 )

Thanks,

What device? If it’s iOS running iOS 9 or later, you can’t access http:// addresses without adding some exceptions to your build.settings. It’s called App Transport Security (ATS). Basically Apple is forcing people to use https:// addresses. It’s 2016 and there is no excuse for a website to not be encrypted (Apple’s thinking, but I happen to agree). In fact iOS 10 will do away with the exceptions with out written approval from Apple. You can read about it here:

https://docs.coronalabs.com/guide/hardware/appleATS/index.html

But in your case, try changing the URL from http:// to https:// and see if that changes things. All Google endpoints should be https: capable now.

And if any one wants to argue about “It costs to much” or “it too difficult” to get an SSL certificate, I would suggest checking out:

https://letsencrypt.org/

Your hosting provider may support them already. Its like a trivial install process. For my host, I was presented a screen of my domain names and a check box. I checked the ones I wanted SSL on, hit the submit button and done.  For those sites running on my full server at Digital Ocean, I had to install a small script, ran it, listed my domains to set SSL up on and hit submit.

I’m using PC, the script works fine on emulator it displays the image, but when I publish it and try it on my android device it doesn’t display the image.

#4

Any messages in your console log? (adb logcat)

#5

On the corona simulator output or in my mobile device? In simulator it works fine, but when I run it on mobile it doesn’t display the image.

The device.

I am going to ball park it and say you need to make sure your internet permission on android.

I’m using android phone. I really didn’t know what happen but it’s working now.

Thanks for your reply,
