Debuggers

Use Cases

Due to all the different ways AppStudio apps can be run, there is no one debugger that will work in all situations. This chart is meant to help you pick which debugger to use.

Pick the row based on what you use as your desktop development machine.

Pick the column based on where you are running the app. Then, look up more information below on using that debugger.

Which Debugger should I use?

	Desktop	iOS WebApp	iOS Native	Android 4.4+ WebApp	Android 4.4+ Native	Android < 4.4 WebApp	Android < 4.4 Native
Mac OS	Chrome	Safari Remote	Safari	Chrome Remote	Chrome Remote	NSBApp	NSBApp
Windows	Chrome	NSBApp	NSBApp	Chrome Remote	Chrome Remote	NSBApp	NSBApp

Desktop is an app which is run in a desktop browser. It can be either run locally or from a server.

Debuggers

Chrome Debugger

The Chrome Debugger is the most commonly one used. It runs on Windows and Mac OS. It can debug apps running on the desktop, and has the most functions. To start it, use Chrome's Tool menu and choose JavaScript Console.

Information on using it is here.

Chrome Remote Debugger

The Chrome Remote Debugger, once started, is very much like the Chrome Debugger. It lets you debug Android 4.4 and later devices. Both web apps and PhoneGap apps can be debugged. You should also have the current version of Chrome on both your desktop and the device.

To start it, use Chrome on the desktop and go to about:inspect

Information on using it is here.

NSBApp Debugger

Use this debugger in cases where the Chrome Debugger does not work. It will be useful for apps running on iOS devices when you are in Windows, as well as Android devices running older versions of Android OS (4.3 or older). It works for both web apps and PhoneGap apps. Web apps need to be deployed to the AppStudio Server.

This debugger does not have the ability to view code or set checkpoints, but otherwise looks like a subset of the Chrome Debugger. It is based in the Weinre ("WEb INspector REmote") 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 the AppStudio Server.

2. It is running on a device as a web app, after having been loaded from the AppStudio Server.

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

Safari Debugger

The Safari Debugger can be used to debug local apps on Mac OS machines. There is little need for it, since the Chrome Debugger will work in the same situations. The interface is a bit different than the one in Chrome. We recommend using Chrome since it is useful in more cases, and there is no need to learn a different debugger.

Safari Remote Debugger

The Safari Remote Debugger is useful for debugging apps on devices if you are using a Mac. It works on both Web Apps and PhoneGap apps.

To use it, connect your iOS device to your Mac using a USB cable. In Safari on your Mac, 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.
