Push notification from app using parse

i am using parse 1.13.0 in nodechef.com i tried setting my app to send notification but i getting some problems.

This is my Manifest:

        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
        android:theme="@android:style/Theme.Translucent" />
</application>

in my application class i have: ParseInstallation.getCurrentInstallation().saveInBackground();

• DeviceToken is empty in _Installation class
• Push not working

All i need is send push notification from my app, in some actions i would like notify all users or some users using Installation channels. Don't care if i will use "parse push" or gcm, just need a simple way to send push notifications from app.

EDIT Push from parse-dashboard is working now, but i cant send push notification from client. I tried a push and got "unauthorized: enable master key". So what i need to do ?

EDIT 2 I created a cloud code but its looks not working get values from request.params:

Parse.Cloud.define("sendPush", function(request,response) {
var _locale = "en-US";//request.params.locale;
var _message = "test";//request.params.message;
var query = new Parse.Query(Parse.Installation);
query.equalTo("localeIdentifier", _locale);
Parse.Push.send({
        data:   {
            alert: _message,
        badge: "Increment",
            sound: "default"
        },
        where: query
    }, {
      useMasterKey: true
    })
    .then(function() {
      response.success("Push Sent!");
    }, function(error) {
      response.error("Error while trying to send push " + error.message);
    });
});

EDIT 3

HashMap<String,String> map = new HashMap<String, String>();
map.put("locale","en-US");
map.put("message","Text added");

ParseCloud.callFunctionInBackground("sendPush",map, new FunctionCallback<Object>() {

    @Override
    public void done(Object object, ParseException e) {
        // toast done
    }
});
