问题 I'm implementing a MediaPlayer . Everything goes smoothly BUT each time I encounter a new error it can be very hard to find its meaning. The official doc is lacking in that area, so a website like stack overflow is the only solution and this time even this does not work (error (1;-107) btw). So is there a centralized point where I can find the list of all the MediaPlayer error codes ? I can't find it in the official documentation, and it would be tremendously helpful to quickly diagnose new

问题 I use a MediaPlayer to play an MP3. Currently I disabled screen orientation changes by using android:screenOrientation="portrait" android:configChanges="keyboardHidden|orientation" in the manifest.

问题 I've tried to find a simple tutorial which explains how to load a video from a URL into the android media player but unfortunately I couldn't find any! I have tried several things to try get it working but still no luck. What is the best way to have a MediaPlayerActivity just load a video from a URL? Thanks EDIT: I have tried the following code as suggested: VideoView videoView = (VideoView) findViewById(R.id.your_video_view); MediaController mediaController = new MediaController(this);

问题 The below code runs smoothly in the emulator from Eclipse, but there are problems when I run it on my Android phone and tablet. public class RingerActivity extends Activity{ /** Called when the activity is first created. */ Button press; boolean tone = true; MediaPlayer mp; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mp = new MediaPlayer(); mp = MediaPlayer.create(RingerActivity.this, R.raw.alarm); //Error
