Extend Your Knowledge
It is needless to say that it is generally not very common among actual real-world applications to consist of only one lonesome activity. Thus, in this second tutorial about Intents, we want to develop an application that has two activities. It shows the basic concept of creating multi activity applications and you can certainly use the knowledge you get from this tutorial to create applications with virtually any number of activities. So, if you are curious about how that is done, look no further, the tutorial is right here.

02/20/2011 – 9:51 pmHey Martin,
thank you for your comment. I guess you refer to the use of ‘R.id.labelRed’, ‘R.id.labelGreen’ and ‘R.id.labelBlue’. Please note that the R class contains all the resources (layouts, strings, graphics, etc.) that are part of the application. Whenever you add something to the ‘RES’ folder, that R class is regenerated by Android and you can find it in the ‘GEN’ folder. It is important to understand that all resources in the R class are available to every class, activity, etc. in the entire application and thus they DO NOT belong to a specific class or activity. In the ColorPicker class I just return the ID of each (globally available) label and the first activity then looks up that ID in the R class and modifies the corresponding element by setting it to a specific color.
I hope this answers your question. If not, let me know!

I would like to thank you for your clear tutorials. They’re really nice when you don’t know where to start and when you find the developer guide complicated to follow. Also the video part is good for me, when i watch you making the apps i really see the meaning of all the components!
I see that it’s a while since the last tutorial. I hope there will be one soon! If not I still want to thank you so much for this kickstart in android developing.

I’m new to android development, and even to java development. I found that i’ts very hard to find good tutorials on the internet, for beginners. I’ve currently watched all your tutorials.
They didn’t only teach me android, but it also teached me the basics of java, and OOP.
It are really great tutorials, and i hope there will soon be a follow-up tutorial
Greetings. (=

03/28/2011 – 11:44 amHI Mathias Reisch,
xtensive arts is more than appreciatve,
fantastic job by Mathias Reisch.
There is a small poem in sanskrit(INDIA)
“Annadanam maha danam – VIDYA DANAM MAHATTARAM |
Annena kshanika thripthihi – yavajjivanthu vidyayaa” ||
Meaning : Feeding a person with food is a great thing in this world. Feeding the same person by transferring the knowledge is far more better thing. The reason is the amount of satisfaction which we get through food is of only one minute or two. But the satisfaction which we can get through the knowledge is of life long.
MATHIAS REISCH IS EMPOWERMENT THROUGH EDUCATION
Thanks & regards

05/26/2011 – 11:36 pmHi Mathias,
Thank you so much for your videos. Is it possible to for you to video on working with a database of resources? Maybe either connecting directly to a SQL database to submit queries, or maybe creating some sort of XML from a database and then parsing the XML.
Cheers,
Craig
