    <p>I need to play youtube video and record video in the same layout. </p> <p>To perform this I search for youtube api and found that android version need to be higher than 2.2, this ok but, i want to use VideoView.</p> <p>I saw some post here about this issue and decide eventually to use this code to watch video in VideoView.</p> <pre><code>videoView = (VideoView) findViewById(R.id.your_video_view); Log.d(TAG,getUrlVideoRTSP(current_url) + " id yotube1 " ); //here type the url... videoView.setVideoURI(Uri.parse(getUrlVideoRTSP(current_url))); videoView.setMediaController(new MediaController(this)); //sets MediaController in the video view videoView.requestFocus();//give focus to a specific view videoView.start();//starts the video </code></pre> <p>this code works, but just with <strong>rtsp</strong> link like this :</p> <pre><code>String exemple = "rtsp://v4.cache3.c.youtube.com/CjYLENy73wIaLQlW_ji2apr6AxMYDSANFEIJbXYtZ29vZ2xlSARSBXdhdGNoYOr_86Xm06e5UAw=/0/0/0/video.3gp"; </code></pre> <p>I have multiple link in url therefore I need code to convert url to RTSP, I can't do this manually, I check some code and all of them do not work...</p> <p>I try this: from here <a href="https://stackoverflow.com/questions/8150074/how-to-get-rtsp-url">How to get RTSP URL?</a></p> <pre><code>public static String getUrlVideoRTSP(String urlYoutube) { try { String gdy = "http://gdata.youtube.com/feeds/api/videos/";

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
