How to check if a device running Android has a speaker on it or not? Meaning is it able to play audio?
Are there any Configuration qualifiers for it? and what about programmatically
EDIT: just bought an Android Wear watch and it does NOT have a speaker so not sure how I would check this

Since API level 21 (most Android Wear based on this level), Android provide a feature, PackageManager.FEATURE_AUDIO_OUTPUT
, witch can be used to detect whether there is a way to output the audio.
I tested this feature on my MOTO 360 (no speaker), it don't has this feature, and Ticwatch (with speaker) do have this feature.
But when I connected a Bluetooth headset to the MOTO 360, it still don't have this feature, this confused me.
So I use AudioManager.isBluetoothA2dpOn()
for further check.
The detection code can be like this:
public boolean hasAudioOutput() {
AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
PackageManager packageManager = getPackageManager();
if (audioManager.isBluetoothA2dpOn()) {
// Adjust output for Bluetooth.
return true;
} else if (audioManager.isBluetoothScoOn()) {
// Adjust output for Bluetooth of sco.
return true;
} else if (audioManager.isWiredHeadsetOn()) {
// Adjust output for headsets
return true;
} else if (audioManager.isSpeakerphoneOn()) {
// Adjust output for Speakerphone.
return true;
} else if (packageManager.hasSystemFeature(PackageManager.FEATURE_AUDIO_OUTPUT)) {
// Has internal speaker or other form of audio output.
return true;
} else {
// No device for audio output.
return false;
}
}

Android API doesn't have any such qualifiers neither there is any library method.
But just a raw idea, try playing some audio and simultaneously record through the mic. Check if they are same. This is not a fool proof way, but just a thought!

Probably most android phones have a speaker i guess :P /.. But if you are asking if you can check whether its connected to a speaker or headphones or something like that..then you can use
if (isBluetoothA2dpOn()) {
// Adjust output for Bluetooth.
} else if (isSpeakerphoneOn()) {
// Adjust output for Speakerphone.
} else if (isWiredHeadsetOn()) {
// Adjust output for headsets
} else {
// If audio plays and noone can hear it, is it still playing?
}
