How to find out if sound is finished in android?

Question

How do I know if a sound has finished playing?

I want to play 2 sounds, but I want one sound to play, and then wait until the first sound is made before the second.

Also, if I wanted to do something else when the sound is finished, how to show its next appearance in the flipper viewer, can I do this?

Right now I'm using SoundPool to play my sounds.

Answer 1

Use the MediaPlayer class and OnCompletionListener

Just an idea ... get the ogg / wav play time length and use your own SoundObject class with a timer member. Update it in some update function. If timer> maxtime + threshold, mark it as ready.

As I decided, this is to create an animation sequence containing the image, sound and delay. Then I can queue them so that I can show the image, and the sound accompanies it, and then switch to another image. I do this with SoundPlayer and a custom view (and not a flipper, although you probably could)

The trick is that you cannot just pause the thread for a delay, you will need to use a handler to send yourself messages to update the user interface in the future.

Here is the handler

handler = new Handler() { /* (non-Javadoc) * @see android.os.Handler#handleMessage(android.os.Message) */ @Override public void handleMessage(Message msg) { if (msg.what == NEXT_ITEM_MSG) { showNext(); } else if (msg.what == SEQUENCE_COMPLETE_MSG) { // notify the listener if (animationCompleteListener != null) { animationCompleteListener.onAnimationComplete(); } } } }; 

The showNext () method simply captures the next element in the sequence, updates the image, plays a sound, and then displays a message for the handler to call showNext after the sequence.

 private void showNext() { if (mRunning) { // Get the first item AnimatedSequenceItem item = currentSequence.getNextSequenceItem(); if (item == null) { Message msg = handler.obtainMessage(SEQUENCE_COMPLETE_MSG); handler.sendMessage(msg); return; } // Show the first image showImage(item.getImageResId()); // Play the sound int iSoundResId = item.getSoundResId(); if (iSoundResId != -1) { playSound(iSoundResId); } // schedule a message to advance to next item after duration Message msg = handler.obtainMessage(NEXT_ITEM_MSG); handler.sendMessageDelayed(msg, item.getDuration()); } } 

Of course, all this requires you to define and hard-code the delays, but, in my experience, you have to do this for the game anyway. I had many occasions when I wanted the delay to be longer than the sound. Here's a code that actually queues items.

 battleSequence.addSequenceItem(R.drawable.brigands, R.raw.beep, 2000); battleSequence.addSequenceItem(R.drawable.black, winning ? R.raw.enemy_hit : R.raw.player_hit, 1500); 

With this approach, I can have all kinds of logic for adding animation elements, changing durations, looping animations, etc. It just required some tweaking to get delays.

Hope this helps.

Sorry it's too late to reply. But I used the isPlaying () API from the media planner to wait for the completion of the first song.

 while(mediaPlyaer.isPlaying()){ }
