Android Implementing Designs for Android Adding Push Notifications from Parse.com Setting Up Push Notifications

App crashed when push sent

Hi, I followed the instructions on parse.com for setting up the push notifications (three times...). But when I try to send a push notification the app crashes. This happened on an emulator and on a real device.

Any suggestions?

See my answer in this thread. Might be your problem as well (Parse version 1.7 has different push behaviour).

Could be a bunch of different things, and here is what we need to do to find out.

Go to your logcat, and make sure you have it at least set for debug, if not verbose.
Run the app again, and initiate the workflow needed to generate the push message. The app will crash, but what we are most interested in is the string of error messages ( mine are in red, yours may be set up different ) that happen right at the end.

Post the whole chunk of them here, and i will help you figure it out. This simple step is probably one of the most important things to get comfortable doing, as you make changes and eventually end up breaking things. Logcat will almost always give you good information on why it stopped working, and the specific activity, class, and or line number where the problem started.

Cool, it looks like you are running into null pointer exceptions, when parse tries to execute some of its built in methods.

Can you copy and paste your entire AndroidManifest.xml?

william parrish

And if you could, also paste the contents of the class you use to initialize your parse api key, and set the installations and callbacks. If you havent changed the names, it should be called ribbitapplication.

package com.simplife.ribbit;

import android.app.Application;

import com.parse.Parse; import com.parse.ParseInstallation; import com.parse.ParseAnalytics; import com.parse.ParseUser; import com.parse.PushService; import com.simplife.ribbit.utils.ParseConstants;

In onCreate, you are missing the part where you setup the necessary callback for the PushService.

Right after you initialize Parse and before your firstcall to .getCurrentInstallation() type in :

PushService.setDefaultPushCallback(this, MainActivity.class)

Try that, see what happens

william parrish

That callback is responsible for the handling of the Pushnotification, and Parse will look for what you define there, and when it tries to handle the push notification.

You using Github or anything like that? So i can see all your class files?
