Answer 1

Try to remove the platform, and then add it again, and then build your application.

So, if you have android as targeted platform execute these commands:

ionic platform remove android
ionic platform add android
ionic build android

My son had a very similar problem, and we never did figure out what caused it. He ended up creating a brand new blank ionic project, and then just copying the www folder from the old project. It worked, and he was able to get things building again. If you try it, you'll also have to re-add your plugins, copy package.json and bower.json, and then rerun bower install and npm install . It's not pleasant, but it might be worth a shot if you're desperate.
