Android WebView無法添加多個javascriptinterface

Question

我發現如果我使用之前添加的界面，則webview無法再添加javascriptInterface。 demo1的

this.webView.loadUrl("http://www.google.com"); 
    this.webView.addJavascriptInterface(test1, "test1"); 
    this.webView.addJavascriptInterface(test11, "test11"); 
    this.webView.addJavascriptInterface(test2, "test2"); 
    this.webView.addJavascriptInterface(test22, "test22"); 

    this.webView.loadUrl("javascript:window.test1.describle('Hello1');"); 
    this.webView.loadUrl("javascript:window.test11.describle('Hello11');"); 
    this.webView.loadUrl("javascript:window.test2.describle('Hello2');"); 
    this.webView.loadUrl("javascript:window.test22.describle('Hello22');"); 

DEMO2

this.webView.loadUrl("http://www.google.com"); 
    this.webView.addJavascriptInterface(test1, "test1"); 
    this.webView.loadUrl("javascript:window.test1.describle('Hello1');"); 
    this.webView.addJavascriptInterface(test11, "test11"); 
    this.webView.addJavascriptInterface(test2, "test2"); 
    this.webView.addJavascriptInterface(test22, "test22"); 

    this.webView.loadUrl("javascript:window.test1.describle('Hello1');"); 
    this.webView.loadUrl("javascript:window.test11.describle('Hello11');"); 
    this.webView.loadUrl("javascript:window.test2.describle('Hello2');"); 
    this.webView.loadUrl("javascript:window.test22.describle('Hello22');"); 

在DEMO2，當我使用的接口，如TEST11，我將被告知無法找到OBJ TEST11

我不知道爲什麼。期待您的建議

交換loadUrl和addJavascriptInterface，並可能做到這一點。

this.webView.addJavascriptInterface(test1, "test1"); 
this.webView.addJavascriptInterface(test11, "test11"); 
this.webView.addJavascriptInterface(test2, "test2"); 
this.webView.addJavascriptInterface(test22, "test22"); 
this.webView.loadUrl("http://www.google.com");
