We've just come across a slightly odd bug. Our game has a function which takes a "screenshot" of the game using display.captureScreen().

This is then scaled down and put into a popup as if you've taken a photo and are seeing a preview: http://i.imgur.com/zmKxze1.png (the area inside the black rect was the previous screen).

 

On some devices (reported on Samsung Galaxy Nexus GT-I9250, Samsung galaxy s2 and MotoRazr) it takes the screenshot but some of the display objects get left out for some reason: http://i.imgur.com/xW2MtiD.jpg

 

In the second image, all text plus the logo at the top and a rect that covers the bottom buttons has not been saved to the screenshot.

 

Our best guess is that somewhere during the process where the screen is assigned to a display object an error is occurring, which prevents the rest of the objects being added, but we're not sure. The only error I've seen in the log when it happened is this one:

I'm not sure that's related though, it seems to be an email error. We do have the option for the user to send the screen capture function to a friend using email - but at this point no email functions have been called.

 

Does anyone have any ideas about what could be happening here?

You need to see if there are crash reports, ways to get the console log of the device, or something to look at.  This "feels" like a  low memory issue since you said its on older devices, or perhaps underpowered GPU's.  Do you have largeheap turned on?

Yes largeHeap is turned on. The game doesn't crash, so there are no crash reports. 

 

I do however have a copy of the log from just before and after the screenshot is taken:

Well there is this:  01-19 20:11:06.890: E/HttpOperation(1044): java.io.IOException: Cannot obtain authentication token

and a crash afterwards.  I don't know what you're app is trying to do at this point, or even if this is from your app..

 

There seems to be something going on with IAP going on too:

The error in question actually begins at this point:

01-19 20:11:01.804: I/Corona(5526): new share popup

I don't think that java.io.IOException error is anything to do with our app, we're not making any network requests at that point.

 

 

All that has happened in our app at this point (with regards to this error) is:

 

Opened a new popup, which is just a rounded rect with a few buttons on it.

01-19 20:11:01.804: I/Corona(5526): new share popup

Checked to see if the device has been rotated (we redraw the popup if it has

01-19 20:11:01.811: I/Corona(5526): [SP] hasRotated = 	false

Add screen capture to group.

01-19 20:11:02.335: I/Corona(5526): cap

As mentioned before - from there the user can send the image via email, but at this point no email functions have been called (showPopup, openURL, etc).

 

I've asked for more logs from the QA guys, so hopefully I'll be able to find out what it is and let you know.

Well native.showPopup() may be suspending your app since it's calling another Android Activity to handle the sharing.  When your app suspends, Android dumps all the OpenGL textures.  It could be a case that screenCapture is firing before the system has a chance to rebuild the display after it resumes.

 

Can you try to capture the screen before you call native.showPopup?

It already is called before native.showpopup.

  • The screen is captured, and the resulting image is shown as a preview on top of a rounded rect.
  • 4 buttons are also then drawn on this rounded rect.
  • Pressing one of these buttons will either: cancel, post to facebook, post to twitter, open email client.

 

The screen capture can be taken and the user will see images/text etc missing from the capture WITHOUT pressing any of those 4 buttons, so Facebook/Twitter/Email/nativePopup etc never come into the mix.

 

I have a longer log from the QA team where they have tried the capture numerous times in one session, and there are no error messages that I can see. It's over 3000 lines long and has some debug code such as our server requests that I'd rather not post, but at any rate whenever the screen capture is made this is what it is showing every time:

I don't see anything out of place there?

I have footage that shows this happening, and hopefully makes it easier to understand what we are doing:

 

https://www.dropbox.com/s/vw727wucxmu5xix/0001850_Reopen.mp4?dl=0%27

 

At 0:05 the user taps a button which places a full screen rect behind the question UI, and then takes a screenshot - you can see that the text just vanishes, as does the icon on the button in the bottom left corner (the timer bar near the top and images next to it are supposed to disappear, so not concerned about those).

As well as the text that disappears, there is also supposed to be a header image which appears at the top, but that is not shown either.

 

Still no errors in the log, and it works on some devices but not others. If it was failing to load an image I'd expect it to throw an error and probably not finish the screen capture process, but that carries on as normal. I also wouldn't expect text that is already there to disappear.
