That's interesting, it looks like you have a problem with your Oracle Java Environment. Did you install the Oracle Java 7 SDK or JRE? You need both the Oracle Java SDK and the Android SDK's for Android development.
Ah, the whole idea of the stored password is to have random bits in there to confuse you. I don't think it's going to be easy to extract the PIN from the store, that would mean PIN's on devices would be completely useless.
You might want to check the power management settings in the BIOS. On some machines, you need to enable power management by the OS, otherwise it doesn't allow the OS to shut down the machine completely.
Well, it really depends on where you wish to go in the future? Perhaps using a CMS like Joomla! or WordPress is better, as there are thousands of completely free templates you can use, as well as millions of free tutorials.
Before you do though, please visit http://www.codecademy.com/ and do the free HTML, CSS and JavaScript courses. Then move on over to https://dash.generalassemb.ly/ and do theirs as well. That will give you a good foundation for getting proper design and responsive elements into whichever web solution you go for.
Phonegap and Titanium Appcelerator are great for small, simple applications, but you quickly run into performance issues, especially on lower-end devices.
Xamarin is a great tool, and certainly something to consider if you only have C# skills in-house, but, it's still not as easy as native Android applications. My biggest gripe with Xamarin is getting layouts to work as expected.
Compared to how simple and easy it is to create layouts in Eclipse or Android Studio, I'd have to say take the week or two required to migrate from C# to Java.
In Android Studio, you will have a Logcat view which will give you a stack trace of the exception. We'll need that to figure out where what goes wrong.
Android is a fickle beast, to put it mildly. I also went the C++ route at first, but found that these 3rd party frameworks, while very productive in the beginning, just weren't well-suited to application development. Corona and Marmalade are excellent for GAME development, PhoneGap and Titanium are great if you mostly have JavaScript skills and can't be bothered to learn Java. Phonegap is of course lighter weight and a bit easier to use than Titanium, but Titanium gives your app a more native look and feel.
Xamarin works rather well, and if you have great C# skills, it can be your friend, but layouts are a real challenge with it, and the license is expensive when you need to use the more advanced features.
I ended up using Eclipse, Android Studio and the native Java build tools for Android. There are fantastic tutorials available on YouTube and https://developer.android.com/index.html which you should take a look at.
I started professional Android development in early 2012, and have worked on games, applications and utility programs, all written using the Android Java developer tools. What you want to do sounds like an application, and for that I highly recommend you go the Java route.
How about gamifying your idea a little bit? Instead of simply showing flashcards, how about giving the user the ability to select multiple answers as well?
I'm not sure what the criteria are for your project, but something that could boost the feasibilty of this as a project is a decent backoffice system that builds the questions, tracks the scores and also a high scores list. You can then create a basic administration system where someone could create the flashcards / questions and publish them to selected students.
On the Android side, this gives you the opportunity to perform some REST calls to get the flashcards or questions and publish the results to the server.
I'm sure your supervisor didn't tell you your idea sucks :) What hints, tips or complaints did you receive? Let us know what the criteria are and we can help you come up with a plan.
you might want to take the time to properly format your question. It sounds like a homework assignment, so try to break it down into steps first.
For example:
You say that you have to place data into an array, integers or Strings. Are you going to be using a single array, or will you be using two arrays, one for the integers and one for the Strings. This is important, as a normal array can only store one type at a time, so either String or integer. If you really need to use a single array, then you have to create an object that you will be placing in the array. This object will then contain both an integer and a String.
My policy on homework questions is that if I do not see someone showing actual code where they have really tried to solve the problem, I won't answer. I think it's probably the same for most folks on this forum, so show us that you have put in the effort and someone will surely help you.
