I have an EditText to input a web link. I want to preview the inputted URL, similar to the function in Facebook, where we post a link and will see an image of the page, with the title on top and URL at the bottom.
How can I develop this in Android?
Use JSOUP after the user enters a link in the editext to parse out your links OG meta tags (this is what FB looks at) scrape out the meta tags:
Here is an example of the meta info you want from a recent nytimes article
<meta property="og:url" content="http://www.nytimes.com/2013/03/16/world/europe/pope-francis-praises-benedict-urges-cardinals-to-spread-gospel.html"/> <meta property="og:type" content="article"/> <meta property="og:title" content="Vatican Rejects Argentine Accusations Against Pope Francis"/> <meta property="og:description" content="The Vatican on Friday formally defended Pope Francis’ role in Argentina’s so-called “Dirty War,” amid accusations that he failed to halt abuses of which he had knowledge."> <meta property="og:image" content="http://graphics8.nytimes.com/images/2013/03/16/world/16vatican/16vatican-superJumbo.jpg"/>
