WebView Methods is not called in android

Question

My Web view is not calling the javascript function it is returning warning like below. Can anybody suggest how to get rid of the below warning.

07-30 10:15:44.031: W/webview_proxy(3770): java.lang.Throwable: Warning: A WebView method was called on thread 'WebViewCoreThread'. All WebView methods must be called on the UI thread. Future versions of WebView may not support use on other threads.

Below is my function.

public boolean onLongClick(View v){
    System.out.println("dfdsf");
    // Tell the javascript to handle this if not in selection mode
    //if(!this.isInSelectionMode()){
        this.getSettings().setJavaScriptEnabled(true);
        this.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        this.getSettings().setPluginsEnabled(true);
        this.loadUrl("javascript:android.selection.longTouch();");
        mScrolling = true;
        //this.setJavaScriptEnabled(true);
    //}


    // Don't let the webview handle it
    return true;
}

Answer 1

As the warning says you are calling the webview methods in the WebViewCoreThread. Thus modify your code like this,

public boolean onLongClick(View v){
    YourActivity.this.runOnUiThread(new Runnable() {
        public void run() {
            this.getSettings().setJavaScriptEnabled(true);
            this.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
            this.getSettings().setPluginsEnabled(true);
            this.loadUrl("javascript:android.selection.longTouch();");
            mScrolling = true;
        }
    });
}

The warning is telling you everything. You are calling the webview methods directly. That means you are calling them on WebViewCoreThread. You have to call them on the UI Thread that means in the Activity which uses this webview.

Like:

WebView wv = (WebView)findViewById(id);
wv.setJavaScriptEnabled(true);
wv.setJavaScriptCanOpenWindowsAutomatically(true);
wv.setPluginsEnabled(true);
wv.loadUrl("javascript:android.selection.longTouch();");

Use This Code I thinks it will work for you,And modified it according to your need ##

    private WebView webView;


    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.web);

        webView = (WebView) findViewById(R.id.web_view);
        webView.setInitialScale(1);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setLoadWithOverviewMode(true);
        webView.getSettings().setUseWideViewPort(true);
        webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
        webView.setScrollbarFadingEnabled(false);
        webView.loadUrl("http://www.youtube.com");

    }
