progress 是这样，貌似少了小数点，前面多了个-号

I'm giving it a go with a fork from this code here https://www.npmjs.com/package/rn-update-apk / https://github.com/mikehardy/react-native-update-apk - released there with an example app to make sure I didn't break anything

The example shows progress and doesn't seem to have floating point issues
