Yup, the IDE is called Eclipse, but Google has a Beta of their own IDE out now, which would surely be easier to use when it is fully functional. Eclipse is complicated because it is general purpose and has multiple layers of setup options, instead of being purpose built. That said, the language is just Java, so no big learning curve if you know any of the C variants.
If your app is nothing but a lost of text codes, then you could make it all as HTML, and just use a single WebView 'Activity' (the Android word for Page) in the app. The only coding required then would be to do a webview.loadurl.
...which is why I'm asking for assistance.
