react-native-preloader

React Native Pre-loader for Android.

During development of React Native on Android hybrid app, we can find that even in a release package with js bundle in assets, the first startup of the entry React Native Activity can still cost over 1 second, which severely effects user experience. What's more, if we exit the React Activity, and enter again, it still costs that much time. Holy shit!

This library is to solve the problem, and let you load the React Native Activity in milliseconds, painlessly.

Support React Native versions:

• 0.30
• 0.31
• 0.32

May also run on other versions, but I have not checked that.

Effects on our application:

TODO

• Check bundle update support.

Run demo

In order to run demo, your should have react-native installed, then

# install dependencies according to package.json
npm install

# package js files into bundle, which will be under assets directory.
sh package.sh

Usage

dependencies {
    compile "com.github.markzhai:react-native-preloader:0.32.0"
}

In the activity which you want to pre-load ReactActivity:

ReactPreLoader.init(this, DemoReactActivity.reactInfo);

Make your ReactActivity extends the one in the library:

public class DemoReactActivity extends MrReactActivity {

    public static final ReactInfo reactInfo = new ReactInfo("HelloWorld", null);

    @Override
    protected String getMainComponentName() {
        return reactInfo.getMainComponentName();
    }

    @Override
    public ReactInfo getReactInfo() {
        return reactInfo;
    }
}

How it works

See ReactPreLoader and MrReactActivity's onCreate.
