AudioView

Simple Android audio view with a few controls. Basically it's a MediaPlayer wrapper. You can choose AudioView2 and start a AudioService to start MediaPlayer in service. See below for more info (and demo app).

See picture

See demo app

Usage with Gradle

1. Add dependency

dependencies {
    implementation 'com.4ert:audioview:{latest-version}'
}

2. Add layout

<com.keenfin.audioview.AudioView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

3. Set file data source

audioView.setDataSource("/path/to/file");
audioView.setDataSource(Uri);
audioView.setDataSource(FileDescriptor);
audioView.setDataSource(List<String/Uri/FileDescriptor>);

4. Control playback if needed

audioView.start();
audioView.pause();
audioView.stop();
audioView.previousTrack();
audioView.nextTrack();

Usage AudioView2 in AudioService

Multiple AudioView2 with different tags can attach to service and play through it, but only one at a time. It's useful while placing AudioView2 in list or recycler view.

1. Create AudioView2 in xml or by code

<com.keenfin.audioview.AudioView2
    android:id="@+id/audioview"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

2. **Start AudioService to handle playback (optional)**

``` java
Intent audioService = new Intent(this, AudioService.class);
audioService.setAction(AudioService.ACTION_START_AUDIO);
startService(audioService);

3. Assign tag for view and attach to service

AudioView2 audio = itemView.findViewById(R.id.audioview);
audio.setTag(position);
if (!audio.attached())
    audio.setUpControls();
try {
    audio.setDataSource(object.getPath());
} catch (IOException ignored) {
}

5. Stop service when you do not need it anymore (optional)

Intent audioService = new Intent(this, AudioService.class);
stopService(audioService);

There is a default behaviour for AudioView2 to start service automatically if it is not running yet. You can disable this by setting AudioView2.setAutoStartServie(false), but you can not omit 2 and 5 steps in this case.

Attach to service to implement your own behaviour

You can attach to AudioService to implement your own view or other behaviour.

1. Add service connection

private ServiceConnection mServiceConnection = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
        mService = ((AudioService.AudioServiceBinder) iBinder).getService();
    }

    @Override
    public void onServiceDisconnected(ComponentName componentName) {
        mService = null;
    }
};

2. Bind/unbind to service

private void bindAudioService() {
    Intent intent = new Intent(getContext(), AudioService.class);
    getApplicationContext().bindService(intent, mServiceConnection, 0);
}

private void unbindAudioService() {
    try {
        getApplicationContext().unbindService(mServiceConnection);
    } catch (Exception ignored) {
    }
}

3. Add broadcast receiver to handle events

private BroadcastReceiver mAudioReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        int status = intent.getIntExtra("status", -1);
        int status = intent.getIntExtra("tag", -1);
        switch (status) {
            case AUDIO_PREPARED:
            case AUDIO_STARTED:
            case AUDIO_PAUSED:
            case AUDIO_STOPPED:
            case AUDIO_PROGRESS_UPDATED:
            case AUDIO_COMPLETED:
            case AUDIO_TRACK_CHANGED:
                break;
        }
    }
};

4. Register/unregister receiver

private void registerAudioReceiver() {
    getContext().registerReceiver(mAudioReceiver, filter);
}

private void unregisterAudioReceiver() {
    try {
        getContext().unregisterReceiver(mAudioReceiver);
    } catch (Exception ignored) {
    }
}

Or send command to service to control playback

• ACTION_START_AUDIO
• ACTION_PAUSE_AUDIO
• ACTION_STOP_AUDIO
• ACTION_PREVIOUS_AUDIO
• ACTION_NEXT_AUDIO
• ACTION_CONTROL_AUDIO (to start/pause depending on current state)
• ACTION_DESTROY_SERVICE (to immediately destroy)

Audio notification for service

For AudioView2 and associated service foreground notification is applied. There are default playback controls plus close icon to stop and destroy service. You can setup following parameters through service intent or by proxying them over AudioView2:

AUDIO_NOTIFICATION_CHANNEL_ID

AudioView2.setServiceNotificationId(int id)

Integer to append to default string channel id for Android 8+

AUDIO_NOTIFICATION_ICON_RES

AudioView2.setServiceNotificationIcon(int icon)

Drawable integer resource to show in status bar for notification

AUDIO_NOTIFICATION_SHOW_CLOSE

AudioView2.setServiceNotificationShowClose(boolean showClose)

Boolean to show close service button or not

AUDIO_NOTIFICATION_MINIFIED

AudioView2.setServiceNotificationMinified(boolean minified)

Boolean to hide previous/next and title views

Styles & options

primaryColor

Set default color for FAB, SeekBar and ProgressBar. By default it uses colorAccent from AppTheme.

minified

Use alternative version of layout if true.

customLayout

Specify custom player layout reference. Must contain:

• ImageButton R.id.play;
• SeekBar R.id.progress;
• ProgressBar R.id.indeterminate.

Optionally:

• TextViews R.id.title, R.id.time, R.id.total_time;
• View R.id.rewind, R.id.forward

If R.id.time defined, then it shows "time/total time" like "00:01/03:55".

If R.id.total_time defined also, then R.id.time shows time like "00:01" and total time shows total like "03:55"

Mutually exclusive with minified. If you want tint your own colors, just omit primaryColor.
