我正在开发HTML5应用程序，当我在android上创建主屏幕的快捷方式时，它的应用程序图标会得到默认的书签图标或fav图标+书签图标。如何为android指定应用程序图标，就像我们可以在iPhone中指定一样

android是否有指定应用程序图标的标签？

使用以下选项：

<link rel="apple-touch-icon-precomposed" href="/apple-touch-icon-precomposed.png"/>

使用javascriptbridge

private class JavaScriptBridge {

  private Context mContext;

  public JavaScriptBridge(Context context) {
    mContext = context;
  }

  public void launchHome() {
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_HOME);
    intent.addCategory(Intent.CATEGORY_DEFAULT);
    mContext.startActivity(intent);

  }
}

声明您的javascriptbridge

private class JavaScriptBridge {

  private Context mContext;

  public JavaScriptBridge(Context context) {
    mContext = context;
  }

  public void launchHome() {
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_HOME);
    intent.addCategory(Intent.CATEGORY_DEFAULT);
    mContext.startActivity(intent);

  }
}

在webview实例中添加该桥的引用

mWebView.addJavascriptInterface(new JavaScriptBridge(theContext), "MyAndroidBridge");

html访问该按钮的方式

<html>
  <head>
    <script type="text/javascript">
      function launchHome() {
        if (typeof MyAndroidBridge === 'undefined') {
          alert('bridge not declared');
        } else {
         MyAndroidBridge.lauchHome();
        }
      }
    </script>
  </head>
  <body>
    <a href="javascript:launchHome();">Launch Home</a>
  </body>
</html>


函数launchHome（）{
如果（MyAndroidBridge的类型==='undefined'）{
警报（“未声明桥”）；
}否则{
MyAndroidBridge.lauchHome（）；
}
}

<link rel="shortcut icon" sizes="196x196" href="icon-196x196.png">

最初，您需要允许Chrome for Android在设置中显示“添加到主屏幕”选项

像这样的起始模板

<!doctype html>
<html>
<head>
    <title>HTML5 app</title>
    <link rel="shortcut icon" sizes="128x128" href="./icns/1410745473_39412.ico">
    <meta name="mobile-web-app-capable" content="yes">
    <meta name="apple-mobile-web-app-capable" content="yes">

<body>
    <h1>Adventures in HTML5 android apps</h1>
</body>
<script type="text/javascript">
    navigator.standalone = navigator.standalone || (screen.height-document.documentElement.clientHeight<40)

    alert(navigator.standalone == true);
    alert(screen.height-document.documentElement.clientHeight)
</script>
</html>
