I am making an Android app in WebView and I need to add a code to upload for Android. I have found this code (BELOW) and I need to make that into a JavaScript instead of java (if possible) I need to tie it to this upload button (below) I would like for it to also work from the website as well.
Screenshot:
Code:
public class MyWb extends Activity {
    /** Called when the activity is first created. */
    WebView web;
    ProgressBar progressBar;
    private ValueCallback<Uri> mUploadMessage;  
     private final static int FILECHOOSER_RESULTCODE=1;  
     @Override  
     protected void onActivityResult(int requestCode, int resultCode,  
                                        Intent intent) {  
      if(requestCode==FILECHOOSER_RESULTCODE)  
      {  
       if (null == mUploadMessage) return;  
                Uri result = intent == null || resultCode != RESULT_OK ? null  
                        : intent.getData();  
                mUploadMessage.onReceiveValue(result);  
                mUploadMessage = null;  
      }
      }  
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        web = (WebView) findViewById(R.id.webview01);
        progressBar = (ProgressBar) findViewById(R.id.progressBar1);
        web = new WebView(this);  
        web.getSettings().setJavaScriptEnabled(true);
        web.loadUrl("http://www.script-tutorials.com/demos/199/index.html");
        web.setWebViewClient(new myWebClient());
        web.setWebChromeClient(new WebChromeClient()  
        {  
               //The undocumented magic method override  
               //Eclipse will swear at you if you try to put @Override here  
            // For Android 3.0+
            public void openFileChooser(ValueCallback<Uri> uploadMsg) {  
                mUploadMessage = uploadMsg;  
                Intent i = new Intent(Intent.ACTION_GET_CONTENT);  
                i.addCategory(Intent.CATEGORY_OPENABLE);  
                i.setType("image/*");  
                MyWb.this.startActivityForResult(Intent.createChooser(i,"File Chooser"), FILECHOOSER_RESULTCODE);  
               }
            // For Android 3.0+
               public void openFileChooser( ValueCallback uploadMsg, String acceptType ) {
               mUploadMessage = uploadMsg;
               Intent i = new Intent(Intent.ACTION_GET_CONTENT);
               i.addCategory(Intent.CATEGORY_OPENABLE);

               Intent.createChooser(i, "File Browser"),

        });  
        setContentView(web);  
    }
