Android Set Speakerphone Programmatically

This article guides you on how to programmatically control the speakerphone feature on your Android device.

Methods

Here are the main approaches to manage speakerphone in your Android applications:

1. Using AudioManager

• This is the most common and reliable way to manage audio routing.
• It leverages the AudioManager class to directly interact with the device’s audio system.

Code Example

import android.media.AudioManager;

// ...

AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
audioManager.setSpeakerphoneOn(true); // Turn speakerphone ON
audioManager.setSpeakerphoneOn(false); // Turn speakerphone OFF

2. Using TelephonyManager (for Calls)

• Specific for handling phone calls.
• Uses the TelephonyManager class and its setSpeakerphoneOn(boolean on) method.

Code Example

import android.telephony.TelephonyManager;

// ...

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.setSpeakerphoneOn(true); // Turn speakerphone ON during a call
telephonyManager.setSpeakerphoneOn(false); // Turn speakerphone OFF during a call

Notes

• Ensure you have the required permissions in your AndroidManifest.xml.
• Handle potential exceptions like IllegalStateException (if the audio manager is unavailable).
