| * <h3>State Diagram</h3> |
| * |
| * <p>Playback control of audio/video files and streams is managed as a state |
| * machine. The following diagram shows the life cycle and the states of a |
| * MediaPlayer object driven by the supported playback control operations. |
| * The ovals represent the states a MediaPlayer object may reside |
| * in. The arcs represent the playback control operations that drive the object |
| * state transition. There are two types of arcs. The arcs with a single arrow |
| * head represent synchronous method calls, while those with |
| * a double arrow head represent asynchronous method calls.</p> |
| * |
| * <p><img src="../../../images/mediaplayer_state_diagram.gif" |
| * alt="MediaPlayer State diagram" |
| * border="0" /></p> |
| * |
| * <p>From this state diagram, one can see that a MediaPlayer object has the |
| * following states:</p> |
| * <ul> |
| * <li>When a MediaPlayer object is just created using <code>new</code> or |
| * after {@link #reset()} is called, it is in the <em>Idle</em> state; and after |
| * {@link #release()} is called, it is in the <em>End</em> state. Between these |
| * two states is the life cycle of the MediaPlayer object. |
| * <ul> |
| * <li>There is a subtle but important difference between a newly constructed |
| * MediaPlayer object and the MediaPlayer object after {@link #reset()} |
| * is called. It is a programming error to invoke methods such |
| * as {@link #getCurrentPosition()}, |
| * {@link #getDuration()}, {@link #getVideoHeight()}, |
| * {@link #getVideoWidth()}, {@link #setAudioStreamType(int)}, |
| * {@link #setLooping(boolean)}, |
| * {@link #setVolume(float, float)}, {@link #pause()}, {@link #start()}, |
| * {@link #stop()}, {@link #seekTo(int)}, {@link #prepare()} or |
| * {@link #prepareAsync()} in the <em>Idle</em> state for both cases. If any of these |
| * methods is called right after a MediaPlayer object is constructed, |
| * the user supplied callback method OnErrorListener.onError() won't be |
| * called by the internal player engine and the object state remains |
| * unchanged; but if these methods are called right after {@link #reset()}, |
| * the user supplied callback method OnErrorListener.onError() will be |
| * invoked by the internal player engine and the object will be |
| * transfered to the <em>Error</em> state. </li> |
| * <li>It is also recommended that once |
| * a MediaPlayer object is no longer being used, call {@link #release()} immediately |
| * so that resources used by the internal player engine associated with the |
| * MediaPlayer object can be released immediately. Resource may include |
| * singleton resources such as hardware acceleration components and |
| * failure to call {@link #release()} may cause subsequent instances of |
| * MediaPlayer objects to fallback to software implementations or fail |
| * altogether. Once the MediaPlayer |
| * object is in the <em>End</em> state, it can no longer be used and |
| * there is no way to bring it back to any other state. </li> |
| * <li>Furthermore, |
| * the MediaPlayer objects created using <code>new</code> is in the |
| * <em>Idle</em> state, while those created with one |
| * of the overloaded convenient <code>create</code> methods are <em>NOT</em> |
| * in the <em>Idle</em> state. In fact, the objects are in the <em>Prepared</em> |
| * state if the creation using <code>create</code> method is successful. |
| * </li> |
| * </ul> |
| * </li> |
| * <li>In general, some playback control operation may fail due to various |
| * reasons, such as unsupported audio/video format, poorly interleaved |
| * audio/video, resolution too high, streaming timeout, and the like. |
| * Thus, error reporting and recovery is an important concern under |
| * these circumstances. Sometimes, due to programming errors, invoking a playback |
| * control operation in an invalid state may also occur. Under all these |
| * error conditions, the internal player engine invokes a user supplied |
| * OnErrorListener.onError() method if an OnErrorListener has been |
| * registered beforehand via |
| * {@link #setOnErrorListener(android.media.MediaPlayer.OnErrorListener)}. |
| * <ul> |
| * <li>It is important to note that once an error occurs, the |
| * MediaPlayer object enters the <em>Error</em> state (except as noted |
| * above), even if an error listener has not been registered by the application.</li> |
| * <li>In order to reuse a MediaPlayer object that is in the <em> |
| * Error</em> state and recover from the error, |
| * {@link #reset()} can be called to restore the object to its <em>Idle</em> |
| * state.</li> |
| * <li>It is good programming practice to have your application |
| * register a OnErrorListener to look out for error notifications from |
| * the internal player engine.</li> |
| * <li>IllegalStateException is |
| * thrown to prevent programming errors such as calling {@link #prepare()}, |
| * {@link #prepareAsync()}, or one of the overloaded <code>setDataSource |
| * </code> methods in an invalid state. </li> |
| * </ul> |
| * </li> |
| * <li>Calling |
| * {@link #setDataSource(FileDescriptor)}, or |
| * {@link #setDataSource(String)}, or |
| * {@link #setDataSource(Context, Uri)}, or |
| * {@link #setDataSource(FileDescriptor, long, long)}, or |
| * {@link #setDataSource(MediaDataSource)} transfers a |
| * MediaPlayer object in the <em>Idle</em> state to the |
| * <em>Initialized</em> state. |
| * <ul> |
| * <li>An IllegalStateException is thrown if |
| * setDataSource() is called in any other state.</li> |
| * <li>It is good programming |
| * practice to always look out for <code>IllegalArgumentException</code> |
| * and <code>IOException</code> that may be thrown from the overloaded |
| * <code>setDataSource</code> methods.</li> |
| * </ul> |
| * </li> |
| * <li>A MediaPlayer object must first enter the <em>Prepared</em> state |
| * before playback can be started. |
| * <ul> |
| * <li>There are two ways (synchronous vs. |
| * asynchronous) that the <em>Prepared</em> state can be reached: |
| * either a call to {@link #prepare()} (synchronous) which |
| * transfers the object to the <em>Prepared</em> state once the method call |
| * returns, or a call to {@link #prepareAsync()} (asynchronous) which |
| * first transfers the object to the <em>Preparing</em> state after the |
| * call returns (which occurs almost right way) while the internal |
| * player engine continues working on the rest of preparation work |
| * until the preparation work completes. When the preparation completes or when {@link #prepare()} call returns, |
| * the internal player engine then calls a user supplied callback method, |
| * onPrepared() of the OnPreparedListener interface, if an |
| * OnPreparedListener is registered beforehand via {@link |
| * #setOnPreparedListener(android.media.MediaPlayer.OnPreparedListener)}.</li> |
| * <li>It is important to note that |
| * the <em>Preparing</em> state is a transient state, and the behavior |
| * of calling any method with side effect while a MediaPlayer object is |
| * in the <em>Preparing</em> state is undefined.</li> |
| * <li>An IllegalStateException is |
| * thrown if {@link #prepare()} or {@link #prepareAsync()} is called in |
| * any other state.</li> |
| * <li>While in the <em>Prepared</em> state, properties |
| * such as audio/sound volume, screenOnWhilePlaying, looping can be |
| * adjusted by invoking the corresponding set methods.</li> |
| * </ul> |
| * </li> |
| * <li>To start the playback, {@link #start()} must be called. After |
| * {@link #start()} returns successfully, the MediaPlayer object is in the |
| * <em>Started</em> state. {@link #isPlaying()} can be called to test |
| * whether the MediaPlayer object is in the <em>Started</em> state. |
| * <ul> |
| * <li>While in the <em>Started</em> state, the internal player engine calls |
| * a user supplied OnBufferingUpdateListener.onBufferingUpdate() callback |
| * method if a OnBufferingUpdateListener has been registered beforehand |
| * via {@link #setOnBufferingUpdateListener(OnBufferingUpdateListener)}. |
| * This callback allows applications to keep track of the buffering status |
| * while streaming audio/video.</li> |
| * <li>Calling {@link #start()} has not effect |
| * on a MediaPlayer object that is already in the <em>Started</em> state.</li> |
| * </ul> |
| * </li> |
| * <li>Playback can be paused and stopped, and the current playback position |
| * can be adjusted. Playback can be paused via {@link #pause()}. When the call to |
| * {@link #pause()} returns, the MediaPlayer object enters the |
| * <em>Paused</em> state. Note that the transition from the <em>Started</em> |
| * state to the <em>Paused</em> state and vice versa happens |
| * asynchronously in the player engine. It may take some time before |
| * the state is updated in calls to {@link #isPlaying()}, and it can be |
| * a number of seconds in the case of streamed content. |
| * <ul> |
| * <li>Calling {@link #start()} to resume playback for a paused |
| * MediaPlayer object, and the resumed playback |
| * position is the same as where it was paused. When the call to |
| * {@link #start()} returns, the paused MediaPlayer object goes back to |
| * the <em>Started</em> state.</li> |
| * <li>Calling {@link #pause()} has no effect on |
| * a MediaPlayer object that is already in the <em>Paused</em> state.</li> |
| * </ul> |
| * </li> |
| * <li>Calling {@link #stop()} stops playback and causes a |
| * MediaPlayer in the <em>Started</em>, <em>Paused</em>, <em>Prepared |
| * </em> or <em>PlaybackCompleted</em> state to enter the |
| * <em>Stopped</em> state. |
| * <ul> |
| * <li>Once in the <em>Stopped</em> state, playback cannot be started |
| * until {@link #prepare()} or {@link #prepareAsync()} are called to set |
| * the MediaPlayer object to the <em>Prepared</em> state again.</li> |
| * <li>Calling {@link #stop()} has no effect on a MediaPlayer |
| * object that is already in the <em>Stopped</em> state.</li> |
| * </ul> |
| * </li> |
| * <li>The playback position can be adjusted with a call to |
| * {@link #seekTo(int)}. |
| * <ul> |
| * <li>Although the asynchronuous {@link #seekTo(int)} |
| * call returns right way, the actual seek operation may take a while to |
| * finish, especially for audio/video being streamed. When the actual |
| * seek operation completes, the internal player engine calls a user |
| * supplied OnSeekComplete.onSeekComplete() if an OnSeekCompleteListener |
| * has been registered beforehand via |
| * {@link #setOnSeekCompleteListener(OnSeekCompleteListener)}.</li> |
| * <li>Please |
| * note that {@link #seekTo(int)} can also be called in the other states, |
| * such as <em>Prepared</em>, <em>Paused</em> and <em>PlaybackCompleted |
| * </em> state.</li> |
| * <li>Furthermore, the actual current playback position |
| * can be retrieved with a call to {@link #getCurrentPosition()}, which |
| * is helpful for applications such as a Music player that need to keep |
| * track of the playback progress.</li> |
| * </ul> |
| * </li> |
| * <li>When the playback reaches the end of stream, the playback completes. |
| * <ul> |
| * <li>If the looping mode was being set to <var>true</var>with |
| * {@link #setLooping(boolean)}, the MediaPlayer object shall remain in |
| * the <em>Started</em> state.</li> |
| * <li>If the looping mode was set to <var>false |
| * </var>, the player engine calls a user supplied callback method, |
| * OnCompletion.onCompletion(), if a OnCompletionListener is registered |
| * beforehand via {@link #setOnCompletionListener(OnCompletionListener)}. |
| * The invoke of the callback signals that the object is now in the <em> |
| * PlaybackCompleted</em> state.</li> |
| * <li>While in the <em>PlaybackCompleted</em> |
| * state, calling {@link #start()} can restart the playback from the |
| * beginning of the audio/video source.</li> |
| * </ul> |
