The Notifier Component Explained – App Inventor

notifier component app inventor
In this App Inventor tutorial we’re going to cover the Notifier component. We’ve been getting a few questions on this in our online App Inventor courses and decided to produce a video explaining the four types of Notifiers you can use in App Inventor.

For those of you who don’t know what the Notifier component in App Inventor does, it allows you to bring up a message that sits on top of your apps that does one of four things:

  1. Displays a message and disappears automatically
  2. Displays a message that disappears when the user clicks a button
  3. Displays a message that give the user two different button options to click
  4. Displays a message that allows the user to input some text, such as a password, before moving on to the next step

Without further ado, here is our Notifier component App Inventor tutorial:

Android is awesome, but did you know you can create iPhone Apps without writing code?

Accessing the Web: Using the App Inventor Web Component

Accessing the web in App Inventor can be done using the Web component or the Activity Starter component. Each has their own pros and cons. This video will show you how to access the web using the App Inventor Web component.

Go here to learn the App Inventor Activity Starter method.

Thanks to JW Tyler for this great tutorial. You can find his App Inventor book here.

Accessing the Web in App Inventor :: Web View or Activity Starter?

There are a couple ways of accessing web pages using App Inventor. One involves using an Activity Starter component to direct the app out to the web and the other involves the Web View component that accesses the web inside of the app itself.

The first method is using the activity starter. This is a great way for beginners to get their apps to access the web. The design process is straight forward and easy to understand.

  • Pro: It’s very simple to set up and it works
  • Con: Users then leave your app and have to find their way back to it

The other method of accessing web pages in App Inventor is by using the Web component. The App Inventor Web component allows you to specify a URL inside your app, and when the web browser opens, it opens inside your app as well.

  • Pro: Your users don’t have to leave your app or choose a browser to access the web
  • Con: It’s a bit more complicated to set up and is less flexible
Which method you choose is up to you and how you want to design your app. There is no wrong way to access the web in App Inventor

App Inventor and the Move to MIT: The Latest Information

Google has officially shut down their version of App Inventor, but MIT is currently working to provide a “large-scale public web service” to the public similar to Google’s App Inventor sometime in the first quarter of 2012.

You can read more about MIT’s progress with App Inventor at MIT’s Developer Blog. You should also check out MIT’s Center for Mobile Learning which is the new home for App Inventor. If you would still like to have access to App Inventor while MIT is working on their roll out, you’ll find information on running your own App Inventor service here.

Here is what MIT had to say about the latest progress with App Inventor:

App Inventor for Android lets people create apps for Android phones by manipulating programming blocks in a web browser.   Since July 2010, Google has run App Inventor  as a large-scale public web service as a part of its Google Labs suite.  With the wind down of Google Labs, as of December 31,  2011, Google ended support of App Inventor.

In order to ensure the future success of App Inventor, Google Research has funded the establishment of the Center for Mobile Learning at the MIT Media Lab.  Sometime in the first quarter of 2012, the Center plans to provide a large scale App Inventor service for general public access, similar to the one Google ran.  MIT’s will be posting progress on getting their public service up and running at MIT Developer’s Blog.

Please visit the MIT Center for Mobile Learning for more information on the future of App Inventor and other innovative mobile learning efforts.
