I have a task - change the ringer volume immediately when phone ringing. For example:
After detecting, that there is incoming call I need to set ringer volume to 0 (mute) and vibrator also should be disabled (if it not disabled already). Then there is delay when I need to perform another code (startComputing();). After that ringer volume should be changed to certain value (f.e.7) and vibrator should be activated. Here is my code:
public class IncomingCallReceiver extends BroadcastReceiver {
private AudioManager amanager;
public void onReceive(Context context, Intent intent) {
if(intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_RINGING)) {
amanager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
amanager.setRingerMode(0x00000000); // no sound and no vibration
startComputing();
amanager.setRingerMode(0x00000002); // normal
amanager.setStreamVolume(AudioManager.STREAM_RING, 7,
AudioManager.FLAG_SHOW_UI
+ AudioManager.FLAG_PLAY_SOUND);
}
}
private void startComputing() {
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
1)The main problem is that after this: amanager.setStreamVolume(AudioManager.STREAM_RING, 7, AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);
ringer does not ring at all, only toast message appears that sound level changed but phone does not play any sound. How this can be changed?
2)Also there is problem that amanager.setRingerMode(0x00000000); does not change Volume and vibration immediately but just in about half a sec.
Thank You in Advance.

I don't think there is anything you can do to overcome the 1/2 sec delay before you mute the ringer. Sometimes it works (ie very short or no delay), sometimes you will hear the ringer for a short period of time.
I think the problem you are having is with the flags passed to setStreamVolume.
Try this:
amanager.setStreamVolume(AudioManager.STREAM_RING, 7,
AudioManager.FLAG_SHOW_UI|AudioManager.FLAG_PLAY_SOUND);
You should be using the bitwise inclusive or (|), and not simple addition (+).

I'm building an Android app that unmute phone when an Incoming call came in phone.
I use BroadcastReceiver to receive incoming call events. I switch phone from mute mode to Ring Mode when BroadcastReceiver receive incoming call events.
And expect Phone will vibrate and Play ringtone.
But Phone only vibrate, can't play ringtone though phone ring set to max sound.
I found many apps on play store those can unmute before call and play ringtone and vibrate both. Example: One App Link
My code Below:
public void onReceive(Context context, Intent intent) {
AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_RING);
if (intent.getAction()!=null && intent.getAction().equals("android.intent.action.PHONE_STATE")){
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)){
audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
audioManager.setStreamVolume(AudioManager.STREAM_RING, maxVolume/2, AudioManager.FLAG_PLAY_SOUND);
}
}
}
I'm working on something very similar. You actually have to play a ringtone after overriding the audio settings. But you only need to do this on Android 6.0+ Get an instance of the ringtone and play it when phone state is ringing else just stop it.
public void onReceive(Context context, Intent intent) {
AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_RING);
Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);
Ringtone r = RingtoneManager.getRingtone(context, uri);
if (intent.getAction()!=null && intent.getAction().equals("android.intent.action.PHONE_STATE")){
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)){
audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
audioManager.setStreamVolume(AudioManager.STREAM_RING, maxVolume/2, AudioManager.FLAG_PLAY_SOUND);
r.play();
}else {
r.stop();
}
}
}
Problems you'll run into with this implementation. You will get multiple ringtones playing because the onReceive method is called many times during Phone State changes. The provides a different context each time onReceive is called and creates a different instance of Ringtone each time. I launched a background service to fix this issue so I could hold a single reference to a context and thus a single reference to Ringtone.
Some devices may not have volume control and may operate at a fixed volume, and may not enable muting or changing the volume of audio streams.
isVolumeFixed()
This method will return true on such devices.
I have the following code in a BroadcastReciver and for some reason won't set the volume to 0.
If I put the same code that sets the volume attached to a button on click event it works just fine. Can someone shed some light as to why this might possibly happen? I know the broadcast receiver is being invoked because I put a log message inside the if statement and it displayed.
public void onReceive(Context context, Intent intent) {
int volume = CommonUtilities.getSharedPreferenceInt(context, CommonUtilities.PREF_FILE, CommonUtilities.PERCENT, -1);
boolean savedSettings = CommonUtilities.getSharedPreferenceBoolean(context, CommonUtilities.PREF_FILE, CommonUtilities.SAVED_SETTINGS, false);
if(volume >= 0 && savedSettings){
Log.v(CommonUtilities.TAG, "Setting the audio");
CommonUtilities.setSharedPreferenceBoolean(context, CommonUtilities.PREF_FILE, "SetAudio", true);
AudioManager audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, AudioManager.FLAG_SHOW_UI);
}
}
If I put this same code in the onClick event it works just fine. The volume is set to 0 and shows the volume UI that it's set to 0.
AudioManager audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, AudioManager.FLAG_SHOW_UI);
Thank you for helping!
I have a working alarm app, but wanted to add a feature where the user gets the choice between "Play alarm continuously till acknowledged" and "play alarm sound once".
I then looked at my alrm ringing code expecting to see some kind of "repeat" flag which I could optionally remove - but there was none. So how do I play the alarm sound just once?
My existing code looks like this:
private void playSound(Context context, Uri alert)
{
mMediaPlayer = new MediaPlayer();
try
{
mMediaPlayer.setDataSource(context, alert);
final AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0)
{
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
mMediaPlayer.prepare();
mMediaPlayer.start();
}
}
catch (IOException e)
{
// oops!
}
}
Actually in each alarm sound there is a FLAG named ANDROID_LOOP which force your sound to loop. Unfortunatly you can't change that flag even using MediaPlayer.setLooping(false).
But you still can manually stop your player after a certain time. For example getDuration will give you the length of your sound.
int duration = mMediaPlayer.getDuration();
Runnable stopSoundRunnable = new Runnable() {
#Override
public void run() {
mMediaPlayer.stop();
}
};
mSoundHanlder.postDelayed(stopSoundRunnable, duration);
I have this method in my main activity
private void beep()
{
AudioManager manager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
manager.setStreamVolume(AudioManager.STREAM_NOTIFICATION, 0,
AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);
Uri notification = RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone r = RingtoneManager.getRingtone(getApplicationContext(),
notification);
r.play();
}
As I understand, notification sound volume should be regulated by STREAM_NOTIFICATION. But notification always plays with the same volume despite that volume number in setStreamVolume method. Why is that?
I went another way. It's not exactly answer to my question but appropriate one. When I play notification in STREAM_MUSIC everything is fine. So notification plays exactly with volume I pass as parameter to the function
private void beep(int volume)
{
AudioManager manager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
manager.setStreamVolume(AudioManager.STREAM_MUSIC, volume, 0);
Uri notification = RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
MediaPlayer player = MediaPlayer.create(getApplicationContext(), notification);
player.start();
}
First of all, I hope you realize that you are attempting to play two notifications right after each other, so there might be a conflict about that. AudioManager.FLAG_PLAY_SOUND and r.play() will both try playing the sound. It is usually enough to give user one type of information, either by UI or by playing the beep with new volume. I suggest you delete one of the flags. If you don't need any, just give it 0.
Coming to the main question, I am not sure if you can set volume level to 0. Try putting 1, like
manager.setStreamVolume(AudioManager.STREAM_NOTIFICATION, 1, AudioManager.FLAG_SHOW_UI);
If you want to mute the notification, try using setStreamMute, which is equivalent to setting the volume to 0.
For my case eventually this seemed to be working.
It would make your audio volume relative to the stream current volume but it was useful for my need.
MediaPlayer player = MediaPlayer.create(getApplicationContext(), notificationUri);
player.setVolume(toneLevel, toneLevel);
toneLevel is between 0.0 - 1.0 so you don't even need to find the range of your stream..
Write a function as follow, or copy and paste the following,
public void ringtone() {
try {
Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), notification);
r.play();
} catch (Exception e) {}
}
and call ringtone() when you want to make a beep notification.
i made a BroadcastReceiver that is listening for changes in the PHONE_STATE. in the onReceive method, i'd like to turn off the system vibrator. i tried different approaches, but non of them worked so far.
AudioManager audioManager = (AudioManager)ctx.getSystemService(Context.AUDIO_SERVICE);
systemVibration = audioManager.getVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER);
audioManager.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER, AudioManager.VIBRATE_SETTING_OFF);
or
Vibrator vib = (Vibrator)ctx.getSystemService(Context.VIBRATOR_SERVICE);
vib.cancel();
or
System.putInt(ctx.getContentResolver(), System.VIBRATE_ON, 0);
or all of them together.
the first approach with the AudioManager really changes the system setting for the vibration, but it does not affect the currently ongoing one.
any ideas?
Simon
Stopping Vibration started by other process is not allowed in android now and thus this hack could stop Vibration or it will give you a feel that it has stopped vibration.
long timea = System.currentTimeMillis();
Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
while ((System.currentTimeMillis() - timea) < 15000) {
v.vibrate(1);
try {
Thread.sleep(10);
} catch (InterruptedException e) {}
}
Try this: (borrowed and modified from Android Source)
AudioManager am = Context.getSystemService(Context.AUDIO_SERVICE);
boolean vibeInSilent = false;
int callsVibrateSetting = AudioManager.VIBRATE_SETTING_OFF;
Settings.System.putInt(getContentResolver(),
Settings.System.VIBRATE_IN_SILENT,
vibeInSilent ? 1 : 0);
//mAudioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
//or (not sure which one will work)
//mAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
am.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER,
callsVibrateSetting);
