2nd sound plays with less integrity?
I want to press the button on the headset, play a sound via the speaker phone, then record a 10 second audio clip. Here is my code:
SoundPool soundPool;
HashMap<Integer, Integer> soundPoolMap;
soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 100);
soundPoolMap = new HashMap<Integer, Integer>();
soundPoolMap.put(SOUND_RECORD_ON,
soundPool.load(context, R.raw.on, 1));
soundPoolMap.put(SOUND_RECORD_OFF,
soundPool.load(context, R.raw.off, 1));
AudioManager mAudioManager = (AudioManager) context
.getSystemService(Context.AUDIO_SERVICE);
float streamVolumeMax = mAudioManager
.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
if (recordStarted == false) {
try { // start recording
audioRecorder.start();
recordStarted = true;
System.out.println(String.format("recording: %s",
recordStarted));
mAudioManager.setMode(AudioManager.MODE_IN_CALL);
mAudioManager.setSpeakerphoneOn(true);
System.out.println("speaker on");
soundPool.play(soundPoolMap.get(SOUND_RECORD_ON),
streamVolumeMax, streamVolumeMax, 1, 0, 1f);
} catch (IOException e) {
e.printStackTrace();
}
} else { // stop recording
try {
audioRecorder.stop();
recordStarted = false;
System.out.println(String.format("recording: %s",
recordStarted));
mAudioManager.setMode(AudioManager.MODE_IN_CALL);
mAudioManager.setSpeakerphoneOn(true);
System.out.println("speaker on");
soundPool.play(soundPoolMap.get(SOUND_RECORD_ON),
streamVolumeMax, streamVolumeMax, 2, 0, 1f);
} catch (IOException e) {
e.printStackTrace();
}
The first sound plays on speaker fine, with very good integrity. However, when I press the button again to stop recording, the sound is nearly inaudible, despite using the same clip. Here is the logcat trace:

Does anybody know why this is the case? I know that in the first portion I did not set the speaker phone back to false; if I do, the sound only gets played through the headset. I am suspecting it is the line that says "too short to be respected." Thank you very much!
--------- UPDATE WITH MEDIAPLAYER CODE -------------
if (action == KeyEvent.ACTION_DOWN) {
Log.e(TAG, "BUTTON PRESSED :D ");
AudioManager mAudioManager = (AudioManager) context
.getSystemService(Context.AUDIO_SERVICE);
MediaPlayer playOn = MediaPlayer.create(context, R.raw.on);
if (recordStarted == false) {
try { // start recording
audioRecorder.start();
recordStarted = true;
System.out.println(String.format("recording: %s",
recordStarted));
mAudioManager.setMode(AudioManager.MODE_IN_CALL);
mAudioManager.setSpeakerphoneOn(true);
System.out.println("speaker on");
playOn.start();
System.out.println("playing on tune");
} catch (IOException e) {
e.printStackTrace();
}
} else { // stop recording
try {
audioRecorder.stop();
recordStarted = false;
System.out.println(String.format("recording: %s",
recordStarted));
playOn.start();
System.out.println("playing off tune");
} catch (IOException e) {
e.printStackTrace();
} finally {
// mAudioManager.setSpeakerphoneOn(false);
// System.out.println("speaker off");
// mAudioManager.setMode(AudioManager.MODE_NORMAL);
}
} // end else
} // end key down action
ok used this code to play the sound, but the 2nd sound is still very quiet (same problem as before)... more suggestions? :D
Turns out, I wasn't supposed to play music in a BroadcastReceiver (detects the media button) because the music would only last for as long as onReceive is executed. Thus, a service had to be created to play before recording.
