I would like help wiith an example I cannot get working
-
The example is here http://www.tutorialspoint.com/android/android_audiomanager.htm[^] In Eclipse I cannot resolve for R. in MainActivity.Java and since I'm brand new to Android, I have no idea how to resolve this. Please help and if I wasn't as descriptive as necessary due to my newbness, ask and I will do my best to answer.

I am facing this same problem with eclipse and it seems to be something to do with the level of the support libraries included in the project. If the compiler cannot resolve items in the resource tree then the
Rclass does not get generated andRis left undefined. I did get it to build once by changing some of the elements in the res/values-vXX tree, but is is not obvious which ones to change. I'm afraid that both eclipse and AndroidStudio seem to be overly engineered, and the slightest mismatch prevents the code from building. I would suggest you try asking the author of the sample. -

Check that you have the highest level of the support libraries available and that you are using the highest level to compile the project.
This may be a dumb question, but I'm not 100% sure how to do that. My project build target is Android 4.4, api 20. Is that what you mean?

Wow! So with Xamarin, I can write in C#, and it will compile to Android native code? Or even IOS code? And I can write in Visual Studio? If this is correct, sign me up!

Yes. For Android, the output is IL that is JIT compiled by Mono at run time. For iOS, IL is compiled (by using a Mac) to machine code at build time. /ravi

Ummm, that is spectacular, I really hope it works as well as I am expecting it to from what you've said and what I read about Xamarin. I'm currently letting the automated installer do its thing and can't wait to try to write c# in VS and then compile to native Android code after a week of pissing in the wind with Android Studio and Eclipse. Does Xamarin allow you to test with the Android virtual machines?

Yes. I recommend using Genymotion. Other emulators suck. I just finished building a successful mobile app POC for a non-trivial feature of our application. My colleague and I targeted iOS and Android. We used Xamarin Forms (that allows shared UI code) for most of our app, as well as custom renderers to build platform specific behaviors for some controls. I'm very positive about Xamarin and am in the process of buying it for myself for use at home. Note, Visual Studio integration is only offered in the Business version, which retails for $1000. I plan to use XStudio for my personal purchase - that license costs $300. Both licenses are perpetual, but support ends after one year, unless renewed. Xamarin also offers monthly trials. See https://store.xamarin.com/[^]. /ravi

Oh, it's not freeware? Wikipedia implied it was freeware like mono. I can't spend $300 or $1000 to learn to develop, I may never have an app in the app store, so that's quite disappointing. I guess I will cancel the download manager :(

Exactly so. I was previously setting mine to the lower level and that failed, but by sticking with the defaults that eclipse sets it seems to work. Unfortunately, I am still learning as well so I cannot offer a better suggestion. You may like to look at some of the recent offerings in the Android articles section as there are quite a few targetting beginners, so some of the authors may be able to help.

Not until they get acquired by Microsoft (as is rumored). Then it'll likely become part of Visual Studio. /ravi

R refers to your application Resources. All UI elements are assigned a unique ID which you can then use in your applicaition code to refer to the UI element. All these IDs are part of the Resource class.
