I am trying to remove sound notification upon receiving gcm notification on android phone. I set data.sound=0
in my code but nothing. Android plays sound even app is closed! Is there any way to achieve my target? Thank you.
public void SendNotification(string deviceId, string message, int badgeCount)
{
string GoogleAppID = "....";
var SENDER_ID = ".....";
WebRequest webRequest;
webRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
webRequest.Method = "post";
webRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8";
webRequest.Headers.Add(string.Format("Authorization: key={0}", GoogleAppID));
webRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));
string postData = string.Format("collapse_key=score_update&time_to_live=108&delay_while_idle=0&data.message={0} &data.time={1} &data.badge={3} &data.sound={4}®istration_id={2}", message, DateTime.UtcNow, regID, badgeCount, "default");
Byte[] byteArray = Encoding.ASCII.GetBytes(postData);
webRequest.ContentLength = byteArray.Length;
Stream dataStream = webRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse webResponse = webRequest.GetResponse();
dataStream = webResponse.GetResponseStream();
using (StreamReader streamReader = new StreamReader(dataStream))
{
String sResponseFromServer = streamReader.ReadToEnd();
streamReader.Close();
dataStream.Close();
webResponse.Close();
}
}
You can use Notification.Builder
with public method setDefaults
.
As mentioned in setDefaults ,
Notification.Builder setDefaults (int defaults)
Set which notification properties will be inherited from system defaults.
Please note that value should be DEFAULT_SOUND
to use the default notification sound.
Solutions given and a couple of comments in this SO post - How to change notification sound by code in android? hope helps you understand better.
