Android Implementing Designs for Android Adding Push Notifications from Parse.com Preparing User-to-User Push Notifications

urgent help please!!

Switch to the file InviteActivity.java. Set pushQuery using the appropriate static method from the ParseInstallation class.

LoginActivity.java
import android.app.Activity;
import android.os.Bundle;
import com.parse.ParseInstallation;
import com.parse.ParseUser;

public class LoginActivity extends Activity {

    /*
     * Some code has been omitted for brevity!
     * This method gets called upon a successful login.
     */

    public void updateParseInstallation() {
        String currentUserId = ParseUser.getCurrentUser().getObjectId();

        ParseInstallation installation = ParseInstallation.getCurrentInstallation();
      installation.put("userId",currentUserId);
      installation.saveInBackground();
    }
}
InviteActivity.java
import android.app.Activity;
import android.os.Bundle;
import com.parse.ParseInstallation;
import com.parse.ParseQuery;

public class InviteActivity extends Activity {

    /*
     * Some code has been omitted for brevity!
     * This method gets called when an invitation is sent.
     */

    public void sendPushNotifications(String playerId) {
      ParseQuery<ParseInstallation> pushQuery = ParseInstallation.getQuery();;

       ParseQuery push=new ParseQuery();
             push.setQuery(query);


    }
}

What's the problem?

it is giving me error

./InviteActivity.java:16: error: cannot find symbol push.setQuery(query); ^ symbol: variable query location: class InviteActivity 1 error

Actually, you dont need the last 2 lines of your code.

thanks a lot Mark Sheehey

copy n paste

import android.app.Activity; import android.os.Bundle; import com.parse.ParseInstallation; import com.parse.ParseQuery;

public class InviteActivity extends Activity {

/*
 * Some code has been omitted for brevity!
 * This method gets called when an invitation is sent.
 */

public void sendPushNotifications(String playerId) {
  ParseQuery<ParseInstallation> pushQuery = ParseInstallation.getQuery();;

}

}

I think you should be using push.setQuery(push);

"push" is where you have set up your query, not the variable "query"

now its saying

/InviteActivity.java:17: error: cannot find symbol push.setQuery(push); ^

symbol: method setQuery(ParseQuery)

location: variable push of type ParseQuery 1 error

ParseQuery pushQuery = ParseInstallation.getQuery();

Is the line of code needed to complete this stage of the challenge.

ParseQuery query = ParseInstallation.getQuery();

this is the code that works in the challenge
