How To Turn Speaker On/off Programmatically In Android Pie And Up

Same as this question and many others from a few years ago: how to turn speaker on/off programmatically in android 4.0 It seems that Android has changed the way it handles this. he

Solution 1:

In Android Pie, I had the same problem. I resolved it using an InCallService with

setAudioRoute(ROUTE_SPEAKER)

Your app needs to be Default phone app.

Solution 2:

I am surprised nobody mentioned TelecomManager.EXTRA_START_CALL_WITH_SPEAKERPHONE.

As an intent:

valuri= Uri.fromParts("tel", PHONE_NUMBER, null)
valintentCall= Intent(Intent.ACTION_CALL, uri).apply {
    putExtra(TelecomManager.EXTRA_START_CALL_WITH_SPEAKERPHONE, true)
    flags = Intent.FLAG_ACTIVITY_NEW_TASK
}
startActivity(intentCall)

Using TelecomManager.placeCall:

val uri = Uri.fromParts("tel", PHONE_NUMBER, null)
val extras = Bundle().apply { putBoolean(TelecomManager.EXTRA_START_CALL_WITH_SPEAKERPHONE, true) }
val telecomManager = getSystemService(TELECOM_SERVICE) as TelecomManager
telecomManager.placeCall(uri, extras)

The default phone app should handle that extra data and enable the speakers.

Remember to ask for android.permission.CALL_PHONE permission.

For this problem please try the following code it is working for me.

AudioManager myAudioManager;
myAudioManager.setMode(AudioManager.MODE_NORMAL);
myAudioManager.setSpeakerphoneOn(true);
