I have written a code to record audio and save it to below file location. private String getFilename() String filepath = Environment.getExternalStorageDirectory().getPath(); File file =. This will make the Facebook Page Plugin responsive, but only on the initial page render, with a minimum width of 180px. I'm still trying to figure out how to make it truly dynamically responsive, in spite of Facebook's caveat (I'll post an update if I ever find the answer). Create an account or log into Facebook. Connect with friends, family and other people you know. Share photos and videos, send messages and get updates. I have an email address and want to find out if there is a Facebook user linked to this address. If there is, then I want to retrieve the url to this users profile page and save it somewhere. I do. It's a page, hence the /pages/ portion of the URL. There is technically an event setup on facebook, but the above URL is the location in which updates will be posted. I would like to just show these updates from this page, as opposed to having to retype them on my website. Facebook has changed how the sharer.php works, as Ibrahim Faour replies to the bug filed with Facebook. The sharer will no longer accept custom parameters and facebook will pull the information that is being displayed in the preview the same way that it would appear on facebook as a post, from the url OG meta tags. from my Android app, I would like to open a link to a Facebook profile in the official Facebook app (if the app is installed, of course). For iPhone, there exists the fb:// URL scheme, but trying the rsrc.php is used by Facebook for version control of all static files, especially images, javascript, and stylesheets. This allows Facebook to apply changes to the main application stack including changes to static content files without breaking functionality for users who are running off an old cached version. It is built into the Facebook architecture as part of the Haste system. Reference To. Facebook will not allow developers pre-fill messages. Developers may customize the story by providing OG meta tags, but it's up to the user to fill the message. This is only possible if you are posting on the user's behalf, which requires the user authorizing your application with the publish_actions permission. AND even then: After hours of trying I've finally found a solution. Delete any app on the website of Facebook (developers.facebook.com) Delete the file debug.keystore under C:\Users\yourUserName\.android Generate a new key (by running your app again) Create a new app on developers.facebook.com and add the new hash key Re-run your app Succes!.
