Failed to create image decoder with message 'unimplemented' #19

Closed pedromcunha closed 2 years ago

pedromcunha commented 3 years ago

Getting an error when trying to print and image, this is on the mCPrint3 printer. I'm passing in a valid http url but it seems to throw this error:

07-22 14:44:37.272  8746  8790 D skia    : --- Failed to create image decoder with message 'unimplemented'
07-22 14:44:37.272  8746  8790 D DRM/DcfDecoder: decodeDrmImageIfNeeded with data

I'm on Android running it in production mode. Any idea if there's a work around? Worst case scenario I feel like a failed image shouldn't cancel all the print actions (which is what's happening now).

I fixed the issue, the url needs to be https otherwise it won't load which creates this error. Should be added to the docs or handled more gracefully.

Although this issue has already been closed and time has passed, I will describe the information for this matter.

When used on iOS and Android, this appears to be due to OS security specifications that restrict non-secure communications (http communications) from within the app. Therefore, https is basically recommended when specifying by URL.

However, if it is desired to use non-secure communication by specifying the image source, it is necessary to configure the following settings in your application.

Thank you.
