The variable B in the second line does not have a value. Let's create a short program with an error and see how it works. How to use the Chrome Debugger Finding Errors in your Program You'll use the JavaScript Console to debug your program. When you click on Run in the IDE, your app is bundled into a web page, which is then opened in Chrome. If you would prefer to use Safari's debugger, Apple has some excellent documentation. Most any browser will work, but we have found the debugging tools on Google's Chrome work well and are easy to use. While the final target for the app may be a device like an iPhone or iPad, it's convenient to test the program on the desktop. The purpose of this tutorial is to demonstrate how to use Google's Chrome browser to debug your AppStudio app.ĪppStudio programs run in a browser. 2.6.2 Debugging an Android device on Mac OS.2.6.1 Debugging an Android device on Windows.RMRBank, the 'flagship' program, then took about a further month as that was so much more complex. The strategy of starting with a relatively difficult program paid off when, using RMRFuel as the template, RMRHome took only a further 48 hrs to code and RMRData about a week. "In the event, RMRFuel took just over a month to bring to a release state, a very short time, attributable to the ease-of-use of the SDK and a very dedicated BETA tester to help me (and the fact I am retired so have plenty of time). So looking back, a surprisingly smooth introduction to a new Software Development Kit." Luckily NSBasic ran a very good forum where the developers could throw in their problems, ideas, and solutions to various aspects, and that, along with the various code sample segments provided and the quick response from NSBasic themselves to any questions, proved invaluable. Naturally this first one took a reasonable amount of time as I learnt the quirks of not just NSBasic, but the underlying JavaScript. So I initially built RMRFuel, which had 3 forms, about 150 controls and a fair amount of SQL coding to do. I decided not to start on my simplest program (RMRHome) or the most complex (RMRBank) but to go for one in the middle range. And once NSBasic incorporated the incremental compiling system, where only those segments of the code that had changed were recompiled, it was very rapid. "Once started I found the ability to develop and test on a PC under Chrome, with it's excellent debugger system, meant that the development process was far quicker than with previous versions. This was also my first venture into the world of SQL database handling so the learning curve on that was very high." Although I considered adapting the original CE code I quickly realised that the syntax differences were so many and varied that I might as well start coding from scratch, although obviously basing the programs UI and logic on the very successful and proven CE versions. "As a long term user of NSBasic products, having used NSBasic(Palm) and NSBasic(CE) to port some of my ex-Psion portfolio across to these platforms, I found NSBasic(App/Studio) very straightforward for the initial porting of my core portfolio. What would an award ceremony be like without an acceptance speech? Here goes. You can try the beta of the improved banking module at. Since the entry was submitted, improvements have been made to the user interface. In fact, the author plans to create an integrated app. It should really be considered together with its 3 siblings. The judges say: This is a very real, very usable app. The program is fully configurable for all international measures." A reminder function is built in for periodic servicing, safety checks or oil changes, and a listing of all other expenses. It maintains a record of Amount Paid, Cost, Gallons/litres, Distance covered and both short-term and long-term Fuel Consumption, and presents it in a text format and as a graph and as a statistical breakdown. "RMRFuel allows you to monitor the fuel consumption and expenses for up to 10 vehicles.
