URL to open facebook app in android [duplicate]

Answer 1

You need to use Intents. Here's how to call the FB application (if it is installed):

Intent intent = new Intent();
intent.setClassName("com.facebook.katana","com.facebook.katana.ProxyAuth");
intent.putExtra("client_id", applicationId);
mAuthActivityCode = activityCode;
activity.startActivityForResult(intent, activityCode);

This code is taken from the Facebook API, which authorizes an action. Ajust to suit your needs. Code is Copyright 2010 Facebook, Inc., licensed under the Apache License, Version 2.0.

Answer 2

myWebView = (WebView) findViewById(R.id.webview); // Create an instance of WebView and set it to the layout component created with id webview in main.xml
        myWebView.getSettings().setJavaScriptEnabled(true);
        myWebView.loadUrl("http://m.facebook.com/pages/xxxxx-xxxxx-xxxxx/xxxxxxxxxx"); // Specify the URL to load when the application starts
        //myWebView.loadUrl("file://sdcard/"); // Specify a local file to load when the application starts. Will only load file types WebView supports
        myWebView.setWebViewClient(new WebViewKeep());
        myWebView.setInitialScale(1); // Set the initial zoom scale
        myWebView.getSettings().setBuiltInZoomControls(true); // Initialize zoom controls for your WebView component
        myWebView.getSettings().setUseWideViewPort(true); // Initializes double-tap zoom control

Check if this works for you.
