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. Following the instructions laid out in Facebook's extending page tokens documentation I was able to get a page access token that does not expire. I suggest using the Graph API Explorer for all of these steps except where otherwise stated. 0. Create Facebook App If you already have an app, skip to step 1. Go to My Apps. Click + Add a New App. Setup a website app. You don't need to change its. 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: I'm developing an Android app and am interested to know how you can update the app user's status from within the app using Android's share intents. Having looked through Facebook's SDK it appears. 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. You can also use pages_show_list permission, if you want only the list of facebook pages the user is admin of. The manage_pages permission will ask the user permission to manage his pages, which can be too intrusive depending on what you need it for. 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). Native mobile applications using Facebook's SDKs will get long-lived access tokens, good for about 60 days. These tokens will be refreshed once per day when the person using your app makes a request to Facebook's servers. If no requests are made, the token will expire after about 60 days and the person will have to go through the login flow again to get a new token. from: developers.facebook.
