Corona Ads and Scaling

gsglawson · September 18, 2016, 11:40pm

Hi,

I am testing the new Corona Ads and I am using the code directly from the documentation example. This is my first attempt at implementing ads and the ads are showing up correctly. However, it doesn’t seem that these ads are scaling when using “letterbox” in the config.lua. The ads appear to remain at a “real” 320x50 instead of scaling to fit. Is this the correct behavior? Do the other ad plugins do this as well?

Thanks,

Scott

Couple screenshots showing this…

Samsung Galaxy S4 phone which seems to display correctly.

Can anyone who is using Corona Ads either confirm or deny that banner ads are scaling properly for you when using scale = “letterBox” in the config.lua? Or, can you confirm that the ad plugin/network that you currently use (not Corona Ads) scales correctly using “letterbox”? Just trying to find a banner ad solution that scales correctly.

Thanks ahead of time!

Looking at the two screen shots, I would guess the first one is actually wrong. That ad looks way bigger than 320x50 in your content area. Also the rest of the app is scaled up as well.

Can you post your config.lua?

Everything there looks file. “letterBox” should be “letterbox”, but the system makes either work, so it’s not a cause of the issue.

You could put in some print statements in your code to dump out all of the sizing values:

display.contentWidth

display.pixelWidth

display.actualContentWidth (and their height variants)

display.contentScaleX

display.contentScaleY

display.screenOriginX

display.screenOriginY

display.statusBarHeight

display.topStatusBarContentHeight

display.viewableContentHeight

display.viewableContentWidth

And see how the two devices compare. There is also additional screen information in system.getInfo(). There are several AndroidDisplay values you can look at as well. Perhaps we may discover what’s different between the two.

Rob,

Below is a small sample app, config.lua, build.settings and output from two devices that show the scaling issue that I am seeing. Note the gray box that I display behind the ads that are 320x50 and how the ads do not scale to fit those boxes using “letterbox”.

Any help is greatly appreciated!

Look at this API: https://docs.coronalabs.com/api/library/system/getInfo.html#androiddisplayapproximatedpi

There are six different options to pass to system.getInfo() that will get the device’s DPI information. Can you print those out as well?

I’m trying to get our engineers to look into this. I was hoping something obvious would show up. I know some Android devices don’t report proper values for the DPI information which can lead to scaling problems but that doesn’t seem to be the case here.e

Interesting. It’s like it’s detecting a tablet and delivering an ad scaled to the tablet, not to the content area. I’ll update the engineers.

Couple screenshots showing this…

Samsung Galaxy S4 phone which seems to display correctly.

Samsung Galaxy Tab A tablet which doesn’t seem to scale.

Can anyone who is using Corona Ads either confirm or deny that banner ads are scaling properly for you when using scale = “letterBox” in the config.lua? Or, can you confirm that the ad plugin/network that you currently use (not Corona Ads) scales correctly using “letterbox”? Just trying to find a banner ad solution that scales correctly.

Thanks ahead of time!

Looking at the two screen shots, I would guess the first one is actually wrong. That ad looks way bigger than 320x50 in your content area. Also the rest of the app is scaled up as well.

Can you post your config.lua?

Everything there looks file. “letterBox” should be “letterbox”, but the system makes either work, so it’s not a cause of the issue.

You could put in some print statements in your code to dump out all of the sizing values:

display.contentWidth

display.pixelWidth

display.actualContentWidth (and their height variants)

display.contentScaleX

display.contentScaleY

display.screenOriginX

display.screenOriginY

display.statusBarHeight

display.topStatusBarContentHeight

display.viewableContentHeight

display.viewableContentWidth

And see how the two devices compare. There is also additional screen information in system.getInfo(). There are several AndroidDisplay values you can look at as well. Perhaps we may discover what’s different between the two.

Rob

gsglawson · September 27, 2016, 9:51pm

Rob,

Below is a small sample app, config.lua, build.settings and output from two devices that show the scaling issue that I am seeing. Note the gray box that I display behind the ads that are 320x50 and how the ads do not scale to fit those boxes using “letterbox”.

Any help is greatly appreciated!

Look at this API: https://docs.coronalabs.com/api/library/system/getInfo.html#androiddisplayapproximatedpi

There are six different options to pass to system.getInfo() that will get the device’s DPI information. Can you print those out as well?
