Beginner's pointers?

Hi chaps,
I've just got myself an O2 XDA Orbit - great device, and now I'm looking for developing for it - just simple things at first, like a Blackjack game, or a simple Today feature with the sun and moon times on it; this sort of thing.
I've got Visual Studio .NET 2003, but I see that in order to program the latest devices, you need VS 2005 (?). So, I've downloaded Embedded Visual Studio C++ v4 with all the SDK's and I'm hoping to develop for an earlier version of Windows Mobile, and hope that it works.
So while I've got all that, I'm now stuck as to where to start! Can anyone point me to a good book, or something online which will help me through a simple CE application? How you do get the Today screen working, for example? I realise that this might be asking a lot, but a couple of pointers would be great - if you could!
Many thanks,
MrP.

I'm just starting out myself with windows mobile programming. You can find a lot of info from msdn. Here is an example Hello app.

You can find a lot of good stuff at the code project site also.

eVC has wizards that will get you going. One thing I found out about using eVC is that you won't be able to debug your programs on a WM5/6 device since the SDK's are not compatible with them. It can be a bit of a challenge to fix bugs without a debugger. I can't get the debugger to work with the emulator either for some reason.
A question for other eVC developers out there. Is it possible to use the emulator to debug programs or do you all have an old PPC2003 device that you use to do your debugging? Or have you all moved on to VS2005?

I've bought visual studio 2005 standard and it is great - it fully supports WM5/6 (with sdk) and runtime debugging - for .exe it works well but I have problems with .dll - I can't debug dll files - does anyone know how to make it?

Pleas look up threads started by vijay555.
He wrote a comprehensive article on the tools and possibilities to begin developing for these devices.
Just as a quick side note:
There is no need what so ever to pay M$ money for VS 2005 if you want to develop in C / C++.
Apps written in eVC++ 4 will work perfectly with WM 5 and 6 and if you need any missing API (not many of those) you have 2 choices:
1) Manually unpack the SDK and link to it.
2) Use implicit linking (that LoadLibrary and GetProcAdress).

x10 Development

Hey guys, im quite new to android developing had to do it for a module at uni.
Just got my x10 and im wondering how i can start making a few apps for it.
I have the ****ty game i wrote for uni and it ran on the HTC Hero i borrowed while debugging, but i cant seem to get netbeans or eclipse to find my new x10 to run my programs on it.
Any help would be greatly appreciated or links to another topic or anything.
Thanks in advanced

type in "Android Tutorial" on youtube and I believe the second link is by UserGroupAtGoogle. It's a 2 hour long video, but its very effective.
It simplified many processes down to a 2 hour lesson. I liked it alot. Just download the Android SDK and the plug-in for your IDE, and that's about it. The video should walk you through the rest. Cheers

So many question, so little time.

Hello all,
I am new to the Android scene and I wanted to find out if there are any good tutorials on app/rom development, what are the programming languages used, etc... I know learning from scratch is probably a long and bumpy road, but it is something I am interested in. I have already rooted and flashed my phone, good times that was. Thank you all for your help.

What's your existing programming experience? You could do worse than check out the anddev forums. App development is principally in Java though you can write parts of apps in C or even assembler.

My existing programming consist of very very very basic python, and some web stuff like HTML and CSS, I would basically have to learn how to program the ones you have mentioned from scratch, I have books for most of those though. I will go check out those forums and see what I can dig up Thanks for the info.

I bookmarked that page thank you, I just got a hold of their Eclipse software and all of their beginner tutorials I can't wait to dive into this stuff.

Me too. I know C, but only have a passing acquaintance with Java & Linux; Android I know even less about, not having encountered it till getting my Hero in February. I'm working my way through Thinking in Java (Eckel) to be followed by Professional Android 2 Application Development (Meier).
Even if your grasp of Python is basic it's still a start - you don't have to struggle again with fundamental procedural programming concepts like conditional execution, program flow control & so forth. Plus Python is an OOP language, aiui (I don't know Python) so you have a head start there too
I've installed Java, Eclipse & Android's SDK on this Windows box, but I'm thinking of dual booting Ubuntu as some things just work better in Linux, especially if one wants to cross compile ROMs. Aiui Cygwin, which I already use, can be a little problematic & when one is likely to be asking for help at times, it's useful to be using a similar set up to most devs.

I have been thinking about dual booting again, I just havent had to time to partition my drive and install some sort of linux release, UBuntu is the one I am most familiar with, which isnt very, but its a start.
I am going through those video tutorials from anddev.org right now, it seems to be similar to Python in the way the coding is done, I am excited.
I have also downloaded the Eclipse program, but I have the pulsar version, it seems to be geared more towards mobile development and I have gotten the Android toolkit installed and I have had the Android SDK from when I rooted my Hero (Which is awesome, running the newest Damage Control) good times.
I think I may have a java book on PDF somewhere as well, I will have to go look.

Atm I can't make up my mind between dual boot & Virtual Box, or maybe both, to see if I can wean myself off m$

I have been thinking about the dual boot option a lot since you mentioned it, not sure what to do, I may wait till this quarters class is over so that if something goes missing. it Sony be a big deal

Eclipse + Android SDK + JDNI/LDAP Access

Hi All,
For sometime I have been looking for a suitable Active Directory Management tool on a mobile device, however have never found anything which quite cuts the mustard. For this reason I have decided to give it a bash myself. I am the proud owner of a lovely shiny new Desire and it feels like it's just crying out for an app of this nature.
Just hoping I might be able to discuss a matter which requires some expertise. I have the latest versions of the Eclipse IDE for Java Developers and the SDK installed, so far I'm having much success with my first GUI builds after following a cracking tutorial Although I can handle the GUI elements (which I normally hate), I'm struggling to forge my first LDAP connection.
I have found info about the "Java Naming and Directory Interface" for java (*however no download) and just wondering if anyone else has had any success using it to code an Android app? I'm not digging for too much info for the moment, just trying to get some assurance that what I am trying to achieve is actually possible.
Not everyone's cup of tea, I know.. But decided it'd be worth asking.
Much Love,
Futurian

What do you use to develop with?

I have been trying to learn how to do some android development for work and keep running into problems. I find it hard to believe that people are able to create a lot of these apps with the Google development tools in such poor condition.
I have set up a development system with eclipse and the android tools. One of the first problems I ran into is ADB crashing whenever I tried to debug and there was a device attached to the system. Didn't matter if I was trying to debug on the device or emulator, ADB would crash. I was finally able to get the problem fixed by using the Composite ADB interface driver instead of the plain ADB interface (would it really hurt Google to add one sentence to the directions to tell people this?)
Now every time I go to debug, the emulator comes up in Chinese/Japaneses. I type in English and it converts it. I can fix it by changing the input method, but I have to do it every time I start the emulator. I have Googled looking for a solution and have found this is a known problem that has been around for almost a year and there is no resolution with it. The bug reports I have found on the android site even lists them still as NEW!
When trying to debug a problem, I wanted to delete the shared preference file for the app as it seems like it had become corrupted and every time it went to read it, the app would force close. (And when this happen, the debugger perspective would come up but for the life of me, I could not find any information as to what caused the fault or any sort of stack trace to look back and see where in my code it failed).
If you are an app developer, are you running into these issues? Have you found ways to work around the problems? I just can't believe that this is the way people develop for this platform. I'm ready to tell my boss that we forget about the platform unless we can find some stable development tools, otherwise we will be spending more time fighting with the tools than working on the app.
If anyone has any suggestions, I would really like to hear them. I'm not a noob when it comes to software development (20+ years as a software engineer), but I have never seen development tools for such a major platform, be this poorly done. What am I missing?

I'm a professional developer as well too. 20 years or so as a C/C++ developer, but I've worked most of my career as a Unix developer. Naturally, I use linux where possible and my Eclipse setup on Gentoo linux is pretty stable. I tried on Win7-64 but it was buggy as heck. I believe that the problem is with Java. There seems to be so many ways to set it up wrong that I'm not sure you can set it up right under windows.
I find it ironic that Oracle is trying to sue Google for making a JVM that actually works!

I havent had any of your mentioned issues. I am running eclipse on a 32 vista machine and a 64 bit windows 7 machine.
Not sure what I may have done different that you for setup. But I followed the Android application development for dummies book. The author goes step by step of what to download and how to install and configure. Even though your software experience is way beyond this book maybe its worth picking it up to read the install notes.

I picked up the book, "Sams Teach Yourself Android Application Development in 24 Hours" and it has a section for setting up the environment too. Followed it to the letter several times and always had this problems. I think the issue comes down to the books were written using version 6 and 7 of the SDK and the current version, 8, has introduced some problems the books don't cover. For example, the tools directory has been split into two directories, tools and platform-tools. When you first download the SDK, you don't get everything you had like before until you update the SDK.
I have talked to several other people who also had the problem with the ADB crashing like I did, even started a thread here about it. No one could get any help anywhere on resolving the issue. I think the problems I have that others don't see is because they started with an earlier version of the SDK.

I have also setup the development platform on a linux system and haven't had the problems I have with Windows 7 64bit. I also feel a lot of the problems have come from the Windows 64bit platform and even windows in general. I tried installing on a clean 64bit and 32bit Windows 7 and was still having the ADB problem. As soon as I get my tax refunds, I'm going to get a work desk setup at home so I can try using my linux system (it sits on the floor with no monitor and is my network server). Boss will really love it if I tell him we have to set up linux platforms to develop on. Guy is a bit of a tight wad when it comes to equipment.

Nope, I didn't have any stability problems with SDK. I use linux 32-bit, didn't try to work on a Windows, MacOS and/or 64-bit arch.

I've not seen any of your problems, either.
FYI, I followed these instructions to set up the env:

(Environment - WinXP/32 netbook)

Eclipse is buggy. The most annoying issue with it is that the auto complete freezes your computer at times.
An alternative is IntelliJ. They offer a free community addition. I work with one dev that swears by it.

I use Windows7x64 and Ubuntu 10.10 to develop my apps. I use IntelliJ mostly because I find Eclipse to be convoluted overcomplicated mess. I think the Android integration in Eclipse is better, especially around editing some of the key XML files but I despise how projects are organized in Eclipse.
The OS you use really doesn't matter the results are the same, once you're up and running the work will be the same so the OS becomes irrelevant. The IDE becomes the differentiator.

I haven't met with the issues you mentioned, but as you said it can be because I installed the sdk a long time ago (after google anounced the eclair). I'm using eclipse and yes, that program is full of bugs, but I read an article about developing for android in Netbeans (my personal favorite). You can read it here: http://androidportal.hu/2011-01-09/fejlesztes-androidra-netbeans-segitsegevel (it's hungarian, but google translate is our friend)

stick to 32-bit Galileo
for the slow autocomplete problem, I've made sure to use eclipse Galileo, something in Helios was causing massive lag. Also make sure you're running the 32-bit version of eclipse, even if your machine is 64-bit, there are definitely some bugs last time I tried to install ADT on 64-bit eclipse.
the new tools directory was a bit of a pain after updating to the latest API but nothing too bad once you figured it out.
I haven't had many of the other problems you mentioned. I always debug with adb logcat from terminal, and you can always hop into the device with adb shell.

I use eclipse every day at work so I've kind of gotten used to all the little quirks. I had the chinese text problem with the emulator, but I do most of my testing on a real phone. I use the emulator just to try out different resolutions.
