    <p>I'm a newbie on android java programming with Eclipse (I have a .NET background) and fail to get a video played in an emulator (nor on an android htc desire)</p> <p>My setup:</p> <ul> <li>Eclipse IDE for Java Developers, Version: Helios Service Release 2</li> <li>Android SDK and ADT Plugin for Eclipse</li> </ul> <p>The video I'm using is a 3gp video I recorded with my htc desire.</p> <p>I have tried the 2 approaches with</p> <ol> <li>VideoView</li> <li>SurfaceView with a MediaPlayer which I took out of the book from Reto Meier "Professional Android 2 Application Development".</li> </ol> <p>I'm targetting Android 2.2 (both in the emulator, as well on my htc desire)</p> <p>Details</p> <p><strong>1. VideoView approach</strong></p> <p>getDuration always returns -1 and even after calling videoView.start() isPlaying is false. Here's the code I'm using:</p> <pre><code>public class MyActivity extends Activity { private static final String FileName = "VIDEO0015.3gp"; private static final String MyTag = "MyActivity"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); VideoView videoView = (VideoView) findViewById(R.id.videoView1); videoView.setKeepScreenOn(true); File clip=new File(Environment.getExternalStorageDirectory(), FileName); if (clip.exists()) { videoView.setVideoPath(clip.getAbsolutePath()); int duration = videoView.getDuration(); if (videoView.canSeekForward()) { videoView.seekTo(duration/2); } videoView.start(); } } } </code></pre> <p>The main.xml file:</p> <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" &gt; &lt;VideoView android:id="@+id/videoView1" android:layout_width="match_parent" android:layout_height="wrap_content"&gt; &lt;/VideoView&gt; &lt;/LinearLayout&gt; </code></pre> <hr> <p><strong>2. SurfaceView with MediaPlayer</strong> With this approach, I get the correct duration (about 15 sec) and isPlaying is true. Both nothing is to be seen and also video playing never is completed.</p> <p>I will add the code if somebody wants to check it.</p> <hr> <p>Thanks for any help, I'm getting desperate.</p> <p>Frank</p>

    1. COSeems odd, could you post your main.xml (don't forget to format it as code - just mark it and press ctrl+k), and have you tried playing another video (not recorded on the phone)?

    2. CO@MByD: Thanks for your help. I have added the contents of the main.xml file. I have played around a bit with the layout settings, but no change. I'm really a newbie, so maybe Im doing something fundamentally wrong. About other videos, I tried one other, which failed with a different error. Because the second attempt (with the surfaceView and mediaPlayer) returns the correct duration and says isPlaying = true I assumed that the video is ok. I will check another video. Is there any video that is guaranteed to work?

    3. COI tried your code and got the same result (with valid video), I don't know why, maybe I'll have time to check it later.
