I'm trying to find a way to detect the plugged/unplugged event on headphone Jack in Xamarin.Android. Is there a way to do it in this? and if it is, how can I implement that functionality?
you can try to convert java code into c#, for example:
[BroadcastReceiver(Enabled = true)]
[IntentFilter(new[] { Android.Content.Intent.ActionHeadsetPlug })]
public class MyBroadcastReceiver : BroadcastReceiver
{
bool Microphone_Plugged_in = false;
public override void OnReceive(Context context, Intent intent)
{
String action = intent.Action;
int iii;
if (Intent.ActionHeadsetPlug.Equals(action))
{
iii = intent.GetIntExtra("state", -1);
if (iii == 0)
{
Microphone_Plugged_in = false;
Toast.MakeText(context, "microphone not plugged in", ToastLength.Long).Show();
}
if (iii == 1)
{
Microphone_Plugged_in = true;
Toast.MakeText(context, "microphone plugged in", ToastLength.Long).Show();
}
}
}
}
And usage:
BroadcastReceiver broadcastReceiver;
IntentFilter receiverFilter;
and initialize value in method OnCreate
of your activity:
broadcastReceiver = new MyBroadcastReceiver();
receiverFilter = new IntentFilter(Intent.ActionHeadsetPlug);
And RegisterReceiver
and UnregisterReceiver
by override method OnResume
and OnPause
protected override void OnResume()
{
base.OnResume();
RegisterReceiver(broadcastReceiver, receiverFilter);
}
protected override void OnResume()
{
base.OnResume();
IntentFilter receiverFilter = new IntentFilter(Intent.ActionHeadsetPlug);
RegisterReceiver(broadcastReceiver, receiverFilter);
}
