Remote Debugging on Android and iOS

By now, most of you have figured out how to use the Chrome or Safari Debugger to look at your app while it is running. (If not, read this!) But did you know you can also debug your app when it is running on a device?

Debugging an Android device on Windows

You will need Chrome 32 or later on both the device and the desktop. Your device needs to be connected by its USB cable.

Follow the instructions here. You will probably need to install the USB driver for your device. Once it is installed, type about:inspect into Chrome’s url bar and you will connect. The debugger will work just like the Chrome Desktop Debugger.

PhoneGap apps work too!

Debugging an Android device on Mac OS

Just like on Windows, except there are no drivers to install.

Debugging an iOS device on Mac OS

Connect your iOS device to your Mac using a USB cable. In Safari, go into the Advanced screen in Preferences. Turn on “Show Develop menu in menu bar”.

Then, from the Develop menu, choose your device and the app you want to debug.

More information is here.

Debugging an iOS device on Windows

Use the NSBApp Debugger.

Start it using the “NSBApp Debugger” in the Run menu. It will then recognize your app in these cases:

1. It is running in a desktop browser, after having been loaded from nsbapp.com.

2. It is running on a device as a web app, after having been loaded from nsbapp.com.

3. It is running on a device as a PhoneGap App. The project property “NSBApp Debugger” must be set to True.

AppStudio 4.1 Released!

AppStudio 4.1 has just been released. It has two important changes:

  1. PhoneGap’s new authorization scheme is now supported. If you are using the default account, you do not need do anything other than install the new release. After May 15th, releases before 4.1 may not work. If you have your own PhoneGap account, read this:
    http://wiki.nsbasic.com/PhoneGap_AuthToken

  2. “Run in Desktop Browser” now uses localhost. Certain features only work when the app is actually deployed. AppStudio now sets up a localhost so these features work even when running on your local machine. There should be no change to your work flow. Everything should work as before, except you no longer need to deploy to nsbapp or to your own server.

AppStudio 4.1 is free for all existing AppStudio 4 users. If you have an older version, you can order it from our order page.

BASIC is 50!

BASIC is 50 years old today. The language has introduced millions of people to programming and is an important language for education and business.

The charm of BASIC, which it still very much has, is that it is easy to just start working and get results. There are very few concepts that need to be mastered before writing your first program, and the learning process to become an expert is a smooth and gradual one. It is a reliable way to get good results, whether you are teaching it or getting an application done.

I’ve hung out with some of the creators of famous BASICs: Tom Kurtz, Steve Wozniak and others. I have had the good luck to work on successful implementations of BASIC for Newton, Windows CE, Palm OS and now iOS, Android and Window Phone.

It’s been great to be able to keep the core of the language intact, while adding features to make it work well with the modern technologies of the web and mobile devices. It’s more powerful than ever and still easy to use.

Here are a few great articles for BASIC’s birthday:

What the $(“#?

Here’s a great question from the web board. What is it with the $(“# you will sometimes see in the code?

It’s a jQuery thing. Valid function names can start with a letter or certain special characters. “$” is a valid character to use in a function name. In this case, it’s the entire function name: $().

(jQuery is a utility library which is included in AppStudio apps)

jQuery’s $() function is a selector. It looks for elements in your app. It has a lot of different ways to select them:
http://api.jquery.com/category/selectors/

You may see something like

  $("#Button1").css("color","red")

The # means to look for an element with the id of “Button1”. What follows is the function to perform on the selected elements. There are a lot of functions that can be called:
http://api.jquery.com

By the way, you can also do the above as follows:

  $(Button1).css("color","red")

Rather than using a selector, we reference the control directly.
