<activity android:hardwareAccelerated="true" /> (though usually not needed): software rendering doesn 39-t support drawrendernode
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) setLayerType(View.LAYER_TYPE_HARDWARE, null) What Triggers This Error
Force-disable hardware acceleration for a specific view to reproduce the error: = Build.VERSION_CODES.O) PixelCopy.request(view
The error is Android's way of telling you: "This drawing command requires the GPU." Turn on hardware acceleration or change your drawing approach.
If you've ever seen the red-lined error in your Logcat: Software rendering doesn't support drawRenderNode you've encountered a hard constraint of Android's 2D rendering pipeline.

// Avoid this view.setDrawingCacheEnabled(true) val bitmap = view.drawingCache // Instead use PixelCopy API (Android O+) if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) PixelCopy.request(view, bitmap, ...)
