I have created a method to open facebook page into facebook app, if app is not existing then opening in chrome
String socailLink="https://www.facebook.com/kfc";
Intent intent = new Intent(Intent.ACTION_VIEW);
String facebookUrl = Utils.getFacebookUrl(getActivity(), socailLink);
if (facebookUrl == null || facebookUrl.length() == 0) {
Log.d("facebook Url", " is coming as " + facebookUrl);
return;
}
intent.setData(Uri.parse(facebookUrl));
startActivity(intent);
Utils.class add these method
public static String getFacebookUrl(FragmentActivity activity, String facebook_url) {
if (activity == null || activity.isFinishing()) return null;
PackageManager packageManager = activity.getPackageManager();
try {
int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;
if (versionCode >= 3002850) { //newer versions of fb app
Log.d("facebook api", "new");
return "fb://facewebmodal/f?href=" + facebook_url;
} else { //older versions of fb app
Log.d("facebook api", "old");
return "fb://page/" + splitUrl(activity, facebook_url);
}
} catch (PackageManager.NameNotFoundException e) {
Log.d("facebook api", "exception");
return facebook_url; //normal web url
}
}
and this
/***
* this method used to get the facebook profile name only , this method split domain into two part index 0 contains https://www.facebook.com and index 1 contains after / part
* @param context contain context
* @param url contains facebook url like https://www.facebook.com/kfc

*/
public static String splitUrl(Context context, String url) {
if (context == null) return null;
Log.d("Split string: ", url + " ");
try {
String splittedUrl[] = url.split(".com/");
Log.d("Split string: ", splittedUrl[1] + " ");
return splittedUrl.length == 2 ? splittedUrl[1] : url;
} catch (Exception ex) {
return url;
}
}
