Silent phone without "don't disturb"

Question

At least on Pixel phones, it's possible to mute the phone from settings. However, I didn't find any Android API to set the phone in this mode as you can see from the screenshot. If I use the AudioManager using the setRingerMode the phone is set into vibrate mode and/or the "Don't disturb" icon is shown. Does anyone know how to use this feature?

Answer 1

Make sure you've declared following permission in AndroidManifest.xml file.

<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

EDIT 2

I've also tested it on Google Pixel 2 API 28 and it is working as expected.

As you can see there is no “Don't Disturb(DND)” button in the notification bar.

EDIT

audioManager.setStreamVolume(AudioManager.STREAM_RING, 0, 0) will let you achieve the desired functionality without "do not disturb" icon.

Output

Original

AudioManger's method name setRingerMode(int ringerMode) allows you to set the mode you want.

Documentation:

Silent mode will mute the volume and will not vibrate. Vibrate mode will mute the volume and vibrate. Normal mode will be audible and may vibrate according to user settings.

This method has no effect if the device implements a fixed volume policy as indicated by isVolumeFixed().

From N onward, ringer mode adjustments that would toggle Do Not Disturb are not allowed unless the app has been granted Do Not Disturb Access. See NotificationManager#isNotificationPolicyAccessGranted().

/**
 * Changes mobile profile to "Silent" or "Vibrate" or "Normal" mode
 *
 * @param context
 * @param mode    - "0 - Silent"
 *                - "1 - Vibrate"
 *                - "2 - Normal"
 */
public static void chooseProfile(Context context, int ringerMode) {
  AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
  if (ringerMode == 0)
    audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
  else if (ringerMode == 1)
    audioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
  else if (ringerMode == 2)
    audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
}
