throw if recycled error while painting tilemap android - android-canvas

Question

I'm having trouble loading my game's tilemap onto the screen. My code seems fine and it doesn't contain any errors. I'm new to android game development and I can't seem t figure out what I'm doing wrong. I've read up on how to access access what's in the assets folder but I don't think I'm getting it right. For this code I'm getting throwifrecycled error, please help.
