How to check if Facebook is installed Android Asked 14 years, 11 months ago Modified 4 years, 6 months ago Viewed 66k times 43 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! JSSDK Unknown Host domain: The Domain you are hosting the Facebook Javascript SDK is not in your app's Javascript SDK host domain list. Please specify your host domain in App dashboard login settings. I am trying to extract the url for facebook video file page from the facebook video link but I am not able to proceed how. For example: The facebook video url I have is: FACEBOOK lehnt alle meine Zahlungsquellen ab Egal was ich Probier, KREDITKARTE o. Abuchen oder 2 unterschiedliche PAYPAL The Page plugin lets you easily embed and promote any public Facebook Page on your website. Just like on Facebook, your visitors can like and share the Page without leaving your site. 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). 6 For my application I need to embed Facebook page in an iframe, here is the html code. But it does not work, any idea why and how to circumvent ? It is just the original Facebook URL and not a user or page address. But this regex can distinguish a normal url from a profile and page url and only accepts the valid one. I want to add facebook share button on my website, that should just post my website's content on the wall. Can anyone help me?.
