Uncaught Error: Error calling method on NPObject的几种解决方案

网上解决方法收集整理：
1、涉及线程安全：

使用WebView的JavaScriptInterface调用startActive()，报错Uncaught Error: Error calling method on NPObject.解决办法是：使用Handler mHandler = new Handler();mHandler.post(new Runnale(){public void run(){// Code in here}});这样子就不报错了。原因可能是线程安全。

2、涉及线程安全2：

WebBrowseActivity.this.runOnUiThread(new Runnable() {@Overridepublic void run() {// TODO Auto-generated method stubwebviewBrowse.loadUrl("javascript:alert('2');  }});

3、涉及线程安全3：

webviewBrowse.post(new Runnable() {@Overridepublic void run() {// TODO Auto-generated method stubwebviewBrowse.loadUrl("javascript:alert('2');  }});

4.自己遇到的坑：android4.1.2

webviewBrowse.loadUrl("javascript:alert('2');
写成了
webviewBrowse.loadUrl("JavaScript:alert('2');  就报这个错误了！！！
