About

This is An Android library for Java and JavaScript communication . iOS repo OCTWebViewBridge

Important

All is builded by webview.loadUrl() , which means this repo is not an JavaScript interpreter .

This bridge handle below problems between Js and java communication

• @JavaScriptInterface cannot inject window.mine.func into JavaScript
• @JavaScriptInterface cannot handle the callback from JavaScript

Principle

see this article WebView JS Java communication

Usage

First

In Java create a handler, like below LogHandler ,and override functions.

public class LogHandler extends JavaHandlerNoCallback{
    public LogHandler(){

    }

    @Keep
    public void log(String args){
        Log.e("js obj: " + getJsObjectName(),args);
    }

    public String getJsDefine(){
        return defineJsObj("log");
    }


    @Override
    public String getJsObjectName() {
        return LogHandler.class.getSimpleName();
    }

    @Override
    public String getProjectObjectName() {
        return "nativeUtils";
    }

    @Override
    public String getJavaHandlerName() {
        return LogHandler.class.getName();
    }

    @Override
    public String getDefaultNativeFunc() {
        return "log";
    }

Second

In JavaScript just call it.

function callJava() {            			       	 	    
    window.nativeUtils.LogHandler.log("123")
}
