Here is my code of custom reciever:

public class CustomPushReceiver extends ParsePushBroadcastReceiver {
    private final String TAG = CustomPushReceiver.class.getSimpleName();

    private NotificationUtils notificationUtils;

    private Intent parseIntent;

    public CustomPushReceiver() {
        super();
    }

    @Override
    protected void onPushReceive(Context context, Intent intent) {
        super.onPushReceive(context, intent);

        if (intent == null)
            return;

        try {
            JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));

            Log.e(TAG, "Push received: " + json);

            parseIntent = intent;

            parsePushJson(context, json);

        } catch (JSONException e) {
            Log.e(TAG, "Push message json exception: " + e.getMessage());
        }
    }

    @Override
    protected void onPushDismiss(Context context, Intent intent) {
        super.onPushDismiss(context, intent);
    }

    @Override
    protected void onPushOpen(Context context, Intent intent) {
        super.onPushOpen(context, intent);
    }

    /**
     * Parses the push notification json
     *
     * @param context
     * @param json
     */
    private void parsePushJson(Context context, JSONObject json) {
        try {
            boolean isBackground = json.getBoolean("is_background");
            JSONObject data = json.getJSONObject("data");
            String title = data.getString("title");
            String message = data.getString("message");

            if (!isBackground) {
                Intent resultIntent = new Intent(context, MainActivity.class);
                showNotificationMessage(context, title, message, resultIntent);
            }

        } catch (JSONException e) {
            Log.e(TAG, "Push message json exception: " + e.getMessage());
        }
    }


    /**
     * Shows the notification message in the notification bar
     * If the app is in background, launches the app
     *
     * @param context
     * @param title
     * @param message
     * @param intent
     */
    private void showNotificationMessage(Context context, String title, String message, Intent intent) {

        notificationUtils = new NotificationUtils(context);

        intent.putExtras(parseIntent.getExtras());

        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

        notificationUtils.showNotificationMessage(title, message, intent);
    }
}

and my ParseQuery:

try {
                    ParseQuery userQuery = new ParseQuery(ParseUser.class);
                    userQuery.whereNear("Location",
                            currentUser.getParseGeoPoint("Location"));
                    userQuery.setLimit(10);
                    userQuery.whereEqualTo("Type", "Doctor");
                    userQuery.whereEqualTo("deviceType", "android");
                    userQuery.findInBackground();
                    // Find devices associated with these users
                    ParseQuery pushQuery = ParseInstallation.getQuery();
                    pushQuery.whereMatchesQuery("user", userQuery);
                    // Send push notification to query
                    ParsePush push = new ParsePush();
                    push.setQuery(pushQuery);
                    push.setMessage("Only users near"
                            + currentUser.getParseGeoPoint("Location")
                            + " will recieve this push notification");
                    push.sendInBackground(new SendCallback() {

                        @Override
                        public void done(ParseException e) {
                            if (e == null) {
                                Toast.makeText(getApplicationContext(),
                                        "Notification Sent", Toast.LENGTH_LONG)
                                        .show();
                            } else {
                                Toast.makeText(getApplicationContext(),
                                        "Notification not Sent",
                                        Toast.LENGTH_LONG).show();
                            }
                        }

                    });

                } catch (Exception e) {
                    e.printStackTrace();
                }

In general terms,

(1) you would be doing this in cloud code. Fortunately it's very easy once you get started. In fact here is a total explanation from a similar question.

Muhc more importantly though,

(2) be aware you're using the wrong tool for the job. You do not use 'Push' for what you are trying to achieve. You should be using PubNub, Firebase, Pusher or a similar service. It is commonplace to use one of these in combination with Parse.
