**10.Android自带的Webview对JS SDK不支持 **
606+
在Android自带的Webview里面引用JS SDK的demo(http://jssdk.demo.qiniu.io/) :
607+
```
608+
public class MainActivity extends Activity {
609+
private WebView webview;
610+
@Override
611+
protected void onCreate(Bundle savedInstanceState) {
612+
super.onCreate(savedInstanceState);
613+
setContentView(R.layout.activity_main);
614+
webview = (WebView) findViewById(R.id.wv);
615+
webview.getSettings().setJavaScriptEnabled(true);
616+
webview.setWebViewClient(new WebViewClient(){
617+
public boolean shouldOverrideUrlLoading(WebView view, String url){
618+
view.loadUrl(url);
619+
return true;
620+
}
621+
});
622+
webview.loadUrl("http://demos.qiniu.com/demo/simpleuploader/");
623+
}
624+
625+
}
626+
```
627+
但是点击选择文件按钮没有反应，这个是Webview对JS不是很支持造成的，解决方法可以引入这个Webview,jar包地址如下:
628+
https://github.com/delight-im/Android-AdvancedWebView/blob/master/JARs/Android-AdvancedWebView.jar
629+
使用的方法文档上都有写，比较简单：
630+
```
631+
private AdvancedWebView mWebView;
632+
@Override
633+
protected void onCreate(Bundle savedInstanceState) {
634+
super.onCreate(savedInstanceState);
635+
setContentView(R.layout.activity_main);
636+
637+
mWebView = (AdvancedWebView) findViewById(R.id.webview);
638+
mWebView.setListener(this, this);
639+
mWebView.loadUrl("http://jssdk.demo.qiniu.io/");
640+
}
641+
```
642+
643+
**11.关于多个按钮选择文件的Demo **
644+
645+
很多用户都在问JSSDK多文件选择的Demo，其实比较简单，只需要在main.js文件里面多new几个Uploader对象就可以了，然后在主页面上里面写好对应的上传的按钮就可以了
646+
这里直接给出main.js和indxe.html里面需要改动的地方:
647+
main.js里面多new几个uploader对象
648+
```
