You can add this line in your AndroidManifest file to your activity tag, by this your activity won't get re-started.

<activity android:name=".Activity_name"
          android:configChanges="orientation|keyboardHidden">

when your activity restarts save the current postion of the video thru this method:

@Override
public Object onRetainNonConfigurationInstance() {
    int videoPosition = videoView.getCurrentPosition();
    Bundle data = new Bundle();
    data.putInt("POSITION", videoPosition);
    return data;
}

and on onCreate() method retrieve this value like this:

final Bundle data = (Bundle) getLastNonConfigurationInstance();

// The activity is starting for the first time...
if (data == null) {
   // start your video for the first time here..
} else {
    // Resume your video from where it was left..
    int videoPosition = data.getInt("POSITION");
// start your video from videoposition....          
}
