Image Classifier OpenGL ES API Error

[AlanLiu96]

Hi,

I've been running into a couple of issues with the image processing. Could anyone shed some light on how to address this?

I'm running the sample code on master adapted for the rainbowHat on top of a Pico i.MX7. My fork is located here, but the only changes to the source shouldn't affect the issue (changing the mapping of a button & LED). Currently using SDK API Level 25 (Android 7.1.1).

Error text below.

Reproduced by

1. Running app
2. Pressing button to trigger Camera "Cheese"

Edit: This may be because the pico i.MX7 doesn't support OpenGL
