Description

We want to detect the current state of headphones connected (true) or disconnected (false). We have an API for that but no example code in documents. http://docs.appcelerator.com/platform/latest/#!/api/Titanium.Android-property-ACTION_HEADSET_PLUG I create an example code but not working.

function doClick() {
 Ti.Android.unregisterBroadcastReceiver(bc);
}
$.index.open();
var onReceived = function(e) {
 Ti.API.info("received!");
 Ti.API.info('Handling broadcast. >> ' + JSON.stringify(e));
 alert('Handling broadcast. >> ' + JSON.stringify(e));
};
var bc = Ti.Android.createBroadcastReceiver({
 onReceived : onReceived
});
Ti.Android.registerBroadcastReceiver(bc,["Titanium.Android.ACTION_HEADSET_PLUG"]);

Index.xml

<Alloy>
 
 <Window class="container"  onClose="doClose" />
 
</Alloy>

Isn't this code example just wrong? The second argument to registerBroadcastReceiver should be an array of references to the Ti.Android.ACTION_* constants like so: Ti.Android.registerBroadcastReceiver(bc, [ Ti.Android.ACTION_HEADSET_PLUG ]); (Note that Ti.Android.ACTION_HEADSET_PLUG is a reference to a constant whose value aliases to the correct String necessary under the hood, it itself is **not** a String)

This is not a bug. The below code works. I've tested it on real devices running Android OS v4.1 and v8.0. When you connect/disconnect a headset to the Android device, it'll display a "Connected" or "Disconnected" label.

   // Create a window with label displaying current headset state.
   var window = Ti.UI.createWindow();
   var label = Ti.UI.createLabel();
   window.add(label);
   window.open();
   
   // Register a headset broadcast receiver.
   var receiver = Ti.Android.createBroadcastReceiver({
   	onReceived: function(e) {
   		// Headset has been connected/disconnected. Display current state via label.
   		if (e.intent.action === Ti.Android.ACTION_HEADSET_PLUG) {
   			var isPluggedIn = (e.intent.getIntExtra("state", 0) != 0);
   			label.text = "Headset is " + (isPluggedIn ? "Connected" : "Disconnected");
   		}
   	},
   });
   Ti.Android.registerBroadcastReceiver(receiver, [Ti.Android.ACTION_HEADSET_PLUG]);
   
   // Unregister above broadcast receiver when exiting.
   window.addEventListener("close", function(e) {
   	Ti.Android.unregisterBroadcastReceiver(receiver);
   });

Like what Chris has said, they're incorrectly passing the Ti.Android.ACTION_HEADSET_PLUG constant in. They should not be double quoting it. For your info, Titanium's Ti.Android.ACTION_HEADSET_PLUG constant returns string "android.intent.action.HEADSET_PLUG", which matches Google's constant here... https://developer.android.com/reference/android/content/Intent.html#ACTION_HEADSET_PLUG Google documents the intent "extras" for this action (such as "state") here... https://developer.android.com/reference/android/media/AudioManager#ACTION_HEADSET_PLUG
