I've studied C++ for a year, but have programmed in PHP for a long time. Java (or any other programming language) isn't too far from the C++ / PHP structure. As a PHP programmer I've been spoiled with php.net. I would like to see a tutorial in "How to get help yourself learning java / android". "This URL is a great place for finding functions" etc

What java snippets you find on the web will work in android? None, because most of them are in JavaEE and Android uses Dalvik?

"Rejected"
Reason: Mostly all Java-Codes will work in Android as you are coding 'normal' Java Wink

, except the GUI-Widget-Stuff and the specialized Android-Stuff. (You are going to learn both here) Exclamation

For learning some specialties take a look at the following URIs.
It's an really nice interactive multiple-choice quiz, which I read to learn from for my programming cours-tests.

For learning Android itself from the base, stay tuned to this forum Smile

Tutorials about all the GUI widgets would be really useful, like Eclipse - SWT or Java2s Wink

Semi-Accepted
Reason: The widgets will be used in all the Tutorials from time to time. If you have a special need/interest, let us know.
i.e.: You'll find a tutorial that uses drawing overlays on a MapView in the late evening hours (Latest tomorrow)

I'd like to see a working tutorial on streaming music with the media player from a url if anyone knows one.

Thanks,

Accepted (refine pls)
Reason: You mean like listening to a radio-stream or sth?

An MPEG audio stream would be cool, but I was thinking just a simple example, streaming a mp3 from a url.

It is quite usefull to optimize/streamline your own development concept. Learning/understanding the tools is a key part. (plus well have to work with the emulator for up to 6 months - no devices, just emulators).

It would be nice to have a basic example which uses XMPP for interaction between several mobile phones. If someone knew a good link where I can learn about using XMPP, I would be glad too.

Hi,

I was thinking of changing the loading up screen from that red ball moving back and forth to something more graphical like something that takes up the whole screen.

Hey - recently posted this to the 'Beginner's' Google Group, but this may be a better place (thanks for making this, by the way!!)

I've been having trouble understanding how the intents system works in the Manifest, along with how file-types and locations on the filesystem are articulated in the code. Part of the confusion is that a lot of Google's example code assumes an app made by Google, so they use their namespace in the tutorials. But the entire framework was made by Google, so I have no idea when to replace 'google' with 'my_app_name', or how any of the lengthy this.that.that.other.... domains get formed.

Some of the many, many questions I was left with from their 'Intents' documentation (http://code.google.com/android/reference/android/content/Intent.html):
1) vnd.android.cursor.item/vnd.google.note is referred to as a file-type for the note application in intents-lingo. I have no idea what makes that a file-type, what items to replace in my own apps with what else (would a notes app called BonzaNotes use something like 'vnd.android.cursor.item/vnd.bonzanote.note', for instance? What does 'vnd' mean, or 'android.cursor.item'?) It would be really helpful to take that apart and explain what each component means.
2) In the line "<action android:value="com.google.android.notepad.action.EDIT_TITLE" />"... Again, what does 'com' stand for? Do I replace 'google' or 'android' in my own apps? How did they come up with that exact string of items?
How do I?
3) In the following lines, what do 'DEFAULT', 'ALTERNATIVE', and 'SELECTED_ALTERNATIVE' mean? These seem like really ambiguous (to the point of useless) categories for much of anything, but they seem to be
important in how the system works.

Hi,

First, i'd like to support the previous request but in a more "general" way : a system global message handler tutorial, to learn how to handle system calls/messages such as time_tick, call_action, answer action... I'm trying to make my "incomingPhoneCallHandler" for many days but it doesn't work out and i'm out of solution

I'd also like a tuto about the emulator just to know what is implemented or not and how to receive a call i.e.

I hope you'll understand me (french developper inside Smile

).

First post - better be something usefull:

How about a Tutorial about a online lookup to xml, rss whateveryouwant to retrieve data?

Something like a RSS Feed Reader...not very special but just the way of getting the information would be worth the effort, I think.

Never come close to really develop anything in java, but i like google, i like android and i once made a network ping pong for java (yeah, thx, I know I'm the big cheese).

I have more ideas my head but skills to write code - but I'm going to learn it!!

Would be nice if the tutorial could be written, or maybe just a hint to another readme, howto, faq on how to make internet lookups etc.

THX!!!

KEEP up your work +-, I like it a lot!
