 This module was designed to be a substitution of `Blob`, there's a set of APIs including basic file system CRUD method, and file stream reader/writer. Also it has a special `fetch` implementation that supports binary request/response body.

-All updates are `backward-compatible` generally you don't have to change existing code unless you're going to use new APIs. In latest version (v0.5.0), new APIs can either `upload` or `download` files simply using a file path. It's much more memory efficent in some use case. We've also introduced `fs` APIs for access files, and `file stream` API that helps you read/write files (especially for **large ones**), see [Examples](#user-content-usage) bellow. This module implements native methods, supports both Android (uses awesome native library  [AsyncHttpClient](https://github.com/AsyncHttpClient/async-http-client])) and IOS.

 Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app. So adding permissions in `AndroidManifest.xml` won't work in Android 6.0 devices. To grant permissions in runtime, you might use modules like [react-native-android-permissions](https://github.com/lucasferreira/react-native-android-permissions).
