Summary:
The bridge implementation on React Android does not currently support boxed numeric/boolean types (the equivalent of NSNumber arguments on iOS), nor does Java support Objective-C's nil messaging system that transparently casts nil to zero, false, etc for primitive types.
To avoid platform incompatibilities, we now treat all primitive arguments as non-nullable rather than silently converting NSNull -> nil -> 0/false.
We also now enforce that NSNumber * objects must be explicitly marked as `nonnull` (this restriction may be lifted in future if/when Android supports boxed numbers).
Other object types are still assumed to be nullable unless specifically annotated with `nonnull`.
Summary:
Added Gzip function to RCTUtils. This uses dlopen to load the zlib library at runtime so there's no need to link it into your project.
The main reason for this feature is to support gzipping of HTTP request bodies. Now, if you add 'Content-Encoding:gzip' to your request headers when using XMLHttpRequest, your request body will be automatically gzipped on the native side before sending.
(Note: Gzip decoding of *response* bodies is handled automatically by iOS, and was already available).
Summary:
As discussed with @nicklockwood in the issue https://github.com/facebook/react-native/issues/1780, the error should be changed to a warning to not break fetch() to send a POST to a remote API without wanting to parse the reply. E.g. google sends back an empty 1x1px gif when POSTing something to google analytics.
