NativeModules is empty

[WesSouza]

I'm trying to use this module together with andpor/react-native-sqlite-storage, but something's preventing it from initializing correctly.

The error I could extract from the thread is:

TypeError: undefined is not an object (evaluating 'NativeModules["SQLite"][method]')

Seems to be related to line 84 on lib/sqlite.core.js that depends on the NativeModule bind for that module.

Is there a limitation on this kind of operation? I couldn't find any reference to NativeModules in the documentation.

I also found that NativeModules is an empty object inside a thread.

Module	Version
React Native	0.55.4
react-native-threads	0.0.12
react-native-sqlite-storage	3.3.6

Hi @wesleydesouza,

To use native packages such as react-native-sqlite-storage in a thread on Android, you will need to modify your MainApplication.java file as outlined in the android section of the README

To include additional native modules in your threads, pass them into the RNThreadPackage constructor after the mReactNativeHost like this: new RNThreadPackage(mReactNativeHost, new ExampleNativePackage(), new SQLitePackage())

On iOS the NativeModules object should not be empty.

@Traviskn thanks for pointing that out!

I guess I'll open a PR and make that section a bit more prominent, or create a dedicated section referencing that somewhere in the README. 😄
