It is the time for you creating an Audio Player for yourself! Is it easy to do? – Yes, it is.

And today, I’m going to make a tutorial that will guide you how to program an Audio Player application on Android step by step. Follows this, you will understand the main flows and critical things that Android provide to developers for creating the useful and powerful applications doing this stuff.

The first thing for your reference is Android Developer site, which is launched at http://developer.android.com. At this time, when i am writing this tutorial, Android API latest version is currently level 21, Android L. And ofcourse, you can also find out a little information about programming to play audio files on Android at this link: http://developer.android.com/reference/android/media/MediaPlayer.html.

The most essential class is android.media.MediaPlayer which enables you to play an audio file on Android. Let take a look on a short Flow Diagram on how to use MediaPlayer to play an audio file below:

The first thing you need is creating an instance of class MediaPlayer through the default public constructor, then calls prepare() before start() to begin playing an audio data. While the MediaPlayer is playing your song, you can use method seekTo(int) with one argument being the time from beginning of song where you want to jump to. This time is calculated in milliseconds. Once Media Player finishes playing your song, it will stop automatically. But if you want to stop playing at some incomplete points, you can call method stop() to stop playing immediately.

private MediaPlayer mPlayer;

 

protected void onCreated(Bundle savedState) {

 

mPlayer = new MediaPlayer();

mPlayer.setDataResource(“/sdcard/test.mp3”);

mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

 

mPlayer.prepare();

mPlayer.start();

}

 

protected void onStop() {

mPlayer.stop();

mPlayer.release();

}

How about pausing and resuming while playing? Certainly you can. Looking at following Flow Diagram:

Sequence Diagram Audio Player – Pause and Resume

Calling start() when Player is stopping will tell Player start playing your song from the beginning. On another hand, Media Player will resume where you stopped before when you called pause() method, and start playing from that point.

Every instance of Media Player can play one song at once. You might want to play more songs at the same time, in that case, you are able to create more instances for more songs and start all of them. But when you want to reuse an instance after finishing one songs to play another song, please do not release it, call reset() instead. After that, you have to reconfigure all information for this instance and prepare() and start() it again. release() method is called only when you finish all things, and you cannot do anything after then.

To repeat playing one song many times, please use setLooping(boolean) method defined for an instance of Media Player. Otherwise, there is another solution which is very useful and flexible. It is using Listeners. When an error occurs while playing a song, or completes playing a song, system will notify for your application if it registered some listeners before.

Audio Player Sequence Diagram – Using Listener

When a listener is invoked, you can easily do some useful tasks for current circumstance. Eg: next to another song after completing playing a song, or reset and try to replay after an error occurring. Then your application will become very reliable and flexible.

How to use:

1. Swipe down the top of the screen to open the Notification Panel
2. Tap to Setting Icon
3. Move to Device Tag and select Accessibility
4. Tap to Vision
5. Move to the Negative Colors feature and clear the check box.
6. Observe: The screen color will be reversed back to the normal.

How to use:
1. Swipe down the top of the screen to open the Notification Panel
2. Tap to Setting Icon
3. Move to Device Tag and select Accessibility
4. Tap to Dexterity and Interaction
5. Select Air wake up
6. Turn ON/OFF switch to enable/disable the air wake up feature.
How to use the air wake up feature:
Firstly, you have to be enable the air wake up feature. The following steps are keys to use this feature:
1. Put the phone on a flat/stable surface when the screen has turned off.
2. Move your hand over the device (gesture device is located at the top of device), make sure to make a smooth movement(the best distance to recognize movement is about 2 inches above the sensor)
3. Observe: the screen is turn on.

  
How to use:
1. Swipe down the top of the screen to open the Notification Panel
2. Tap to Setting Icon
3. Move to Device Tag and select Accessibility
4. Tap to Dexterity and Interaction
5. Select Interaction Control
6. Turn ON/OFF switch to enable/disable the interaction control feature.

How to use the interaction control feature:
Now, let assume that the interaction control feature is enable in your Galaxy S5. You will confuse how to use this function. I will show you how to use it.
Example you are viewing a photos of an album in Galary App. Please go to following steps:
1. Press the Home key and the Volume down key simultaneously. This will be available if you are enable the interaction control feature.
2. You will see the outline of the area showing in the screen. Draw in the area you want to restrict or select Block whole screen option. This will block whole screen.
3. Tap Done Button.
4. To exit from this mode, there are 2 ways:
– Press the Home key & Volume down key simultaneously
– Press the Home key three times quickly.

Finally, the Interaction Control is ON/OFF depended on your selection. It is very useful for managing and controlling your data.

Galaxy S5 sets the duration of long press to a short delay or 0.5 seconds in default. This will brings you some difficulty for doing some functions.

But if you observe more inside Galaxy S5, you can see that it has an accessibility feature named Press and Hold Delay which will help you set the recognition time for long press as well as delay. By this setting, you can control/set time the device should delay before opening any functions/actions.

How to use:

1. Swipe down the top of screen to open the notification panel and then tap to setting icon
2. From the setting function, select Device Tag and scroll down to Personalization section and then tap to Accessibility.
3. Tap to Dexterity and interaction
4. Tap to Press and Hold Delay and select duration time you want to setup.

From these steps, the Press and Hold Delay has been set.

Finally, the setting is not so difficult if you take a look above steps. Hope you enjoin it!
