Learn on youtube, i thinks it's best way : build mobile apps - YouTube

LWell the reason I don't want to do that is mainly because it's all over the place. There's no one best way to learn on Youtube. I was hoping someone knew of a site that pulls it all together conceptually; the knowledge that is. I'm great with concepts.

There are many platforms. You need to know for which phone the people will use the app the most. If you want that it supports all phones then you need to learn all API's available (e.g. Android).

Have a look at MobileTuts - Mobiletuts+ | iPhone, Android, Windows and BlackBerry mobile development tutorials. they have a great library of tutorials from which you could easily pick up some skills.

Hello there,

Look up some local "application development" courses. You'll find a lot of mixed information online.

Guillermo-

As far as my thinking concern Andriod apps is very good for you and also search some videos in Youtube this will very good for you...

Android and iPhone both are best platform to develop apps.You can develop games like android,local search help apps to help unknown people to search anything.

At first choose your platform Androyed or iPhone ???
Earn strong basic on java or objective c according to your choice ,
then use phonegap ,
you can see it;s feature from it's official site.

Firstly you have to select which apps you want to learn.

I'll just try to consolidate what everyone is telling you already. Android and IOS are two different animals.

You need Java skills for Android and...
Objective C for IOS.
Unless you are extremely driven, you aren't going to be able to pull off both at one time (learning that is). That said, if your idea fits within certain criteria, you could use a RAD or Rapid Application Development platform to build your app in the language of your choice. Google around for dragonrad or rhodes mobile and you'll see what I'm talking about.

These are tool sets that allow you to develop in say, Ruby or C or some other language and compile using their software into the correct code for the various devices. The drawbacks are that usually these companies hook in to your data and charge your for queries or charge based on number of download/activations etc. It been a while since I looked so you'll have to do some home work but at least there are options.

The point I forgot was - these companies teach you all you need to know about programming for their platforms without having to get specific about the big 3. (Android, IOS and BB)

I don't know if it's any good but one friend who work in china in a company doing mobile apps sent me this:
Mobile App Development Platform | Sencha Touch | Products | Sencha
But I don't feel like jumping on it right now.. I have another goal to reach first using traditional sites..
The docs/tutorials: http://docs.sencha.com/touch/2-0/

If you're going for Apple, you will have to get XCode. It's not that hard building an App with the graphic interface that is provided in the software. You will have to learn a little programing though.

If you're looking for a game, it gets much more complicated than that. You would need a team of people and much more time to develop.
