我正在研究一個使用videoView在應用程序內部顯示.3GP視頻文件的小型項目。我的代碼在模擬器中工作正常，但是在物理設備（Samsung Nexus S）上，它只能通過WiFi工作，並在3G上超時。下面是我使用下面通過3G連接的Android videoView
<?xml version="1.0" encoding="utf-8"?>
<VideoView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/videoView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
public class VideoViewActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.videoplayer);
Bundle info = getIntent().getExtras();
String path = info.getString("link");
VideoView videoView = (VideoView) findViewById(R.id.videoView);
MediaController mediaController = new MediaController(this);
mediaController.setMediaPlayer(videoView);
videoView.setVideoPath(path);
videoView.setMediaController(mediaController);
videoView.requestFocus();
videoView.start();
mediaController.show();
XML文件中的代碼下面是用於WiFi和3G的logcat的
在3G（不工作）

Over WiFi（works）

I/OMXCodec( 81): [OMX.SEC.MPEG4.Decoder] video dimensions are 320 x 240
是否有什麼理由videoView不會在3G上工作？我用錯了嗎？是否有更好/更簡單的方式在Android中顯示視頻？我不介意使用其他文件類型3GP只是一個例子。
任何幫助將不勝感激。謝謝。
