In your html head add this small piece of js: var video = document.getElementById(‘video’); video.addEventListener(‘click’,function(){ video.play(); },false); Or, just add an onlick attribute directly to your html element: <video src=”https://stackoverflow.com/questions/5278262/your_video” width=”250″ height=”50″ poster=”your_image” onclick=”this.play();”/>

Access ordered images and video in same Cursor

After lots of research and playing around with source code, I’m finally a bit more familiar with the Android filesystem. To get a single Cursor which can access information about both Images and Video I used the following: // Get relevant columns for use later. String[] projection = { MediaStore.Files.FileColumns._ID, MediaStore.Files.FileColumns.DATA, MediaStore.Files.FileColumns.DATE_ADDED, MediaStore.Files.FileColumns.MEDIA_TYPE, MediaStore.Files.FileColumns.MIME_TYPE, MediaStore.Files.FileColumns.TITLE … Read more
