Personally I suggest to study Java first so you won't spend a lot of time googling this and googling that. That will kill your productivity. 

And if I'm allowed to suggest some books then I suggest <a href="http://shop.oreilly.com/product/0636920012825.do">Head First Android Development</a> and/or <a href="http://shop.oreilly.com/product/0636920010364.do?green=23824853889&amp;cmp=af-mybuy-0636920010364.IP">Programming Android</a>.

On the other hand and since you are proficient in C and knowledgeable in C++, iOS development should really be easier to you to pick since Objective-C is a minimal programming language built on C. But of course, it is your call.

blocks|key|5441408|text|我觉得你应该直接跳进去。Java与C%2B%2B非常相似，您只需要克服语法上的驼峰。你应该得到一个很好的参考资料，比如dietel，如何编写程序，然后直接去做。随着时间的推移，你会学到你需要的东西。您的编程经验将帮助您提高速度，更快地创建您的应用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5441409|我还建议“忙碌的安卓代码指南”和新设计的Android开发者指南|offset|length|5441410|这本书值得买，因为这本书的作者非常活跃，可以帮助你很多通过你的学习曲线。|5441411|希望这能有所帮助|entityMap|0|LINK|mutability|MUTABLE|url|http://commonsware.com/Android/Android-1_0-CC.pdf^0|0|4|B|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@$D|S|E|T|1|U]]|A|$]]|$1|F|3|G|5|6|7|V|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|W|8|@]|9|@]|A|$]]]|J|$K|$5|L|M|N|A|$O|P]]]]

I think you should just jump right in. Java is similar enough to C++ that all you will have to get over is the syntax hump. You should just get a good reference like the dietel how to program book and just go for it. You will learn what you need as you go along. Your programming experience will help you get up to speed quicker on creating your apps. 

I would also suggest <a href="http://commonsware.com/Android/Android-1_0-CC.pdf">The Busy Coder's Guide to Android</a> and the newly designed Android Developer Guide

The book is worth purchasing as the writer of the book is very active and can help you alot through your learning curve.

Hope this helps

I would have a play around with Java for a few days just to see if you like it, then just jump right in no better way to learn than get your hands dirty.

Your programming background will help you. There's a lot of good tutorial sites that can ease you into android and java at the same time just try googling for them. Most of all ENJOY!

<blockquote>

</blockquote>

Given that you target Android, it makes sense to simply pick their official tutorial of Getting Started kind and start studying it. If it is necessary / desirable to study Java along the way, you can expect this to be mentioned in this tutorial.

Per my recollection early versions of Android tutorials were of acceptable quality. I didn't work with it for quite a while though.

Answering to a rather old thread, but just had to, since none of the answers or comments highlighted what I believe is a very important point i.e. "learning Object Oriented Programming (OOP)". Especially so, in the light of what OP wrote:-

<blockquote>
 ... quite proficient in C and know some C++, but never touched Java...
</blockquote>

That might indicate, that OP's Object Oriented Programming (and potentially Design) skills might need some propping up. At least, it did so in my case, and I'd have made a very similar statement.

I'd suggest learning what is called "Core Java", and becoming proficient and then, the switch to Android programming would seem much easier. The benefit of that approach is that Java forces OOP, in following ways --

<ul>
<li>Clean (as in Puritan sense)</li>
<li>Easy to grasp (as in simplicity)</li>
<li>The only way (instead of having non-OOP alternative)</li>
</ul>

Also, "Core Java" can be learned pretty quickly for someone already fairly familiar with C/C++.

blocks|key|1705609|text|我决定直接跳到Android系统，一边学习Java，一边学习Java。Start通常很容易--您可以从Android开发人员站点获得Android开发工具，在那里您还可以找到一些教程来帮助您完成第一步。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1705610|然而，如果没有适当的Java知识，Android开发很快就会变得势不可挡(至少对我来说是这样)。幸运的是，这里有专门为Android开发学习Java的教程。您可以找到它们这里+(它们是为那些已经知道另一种语言的人设计的，比如C%2B%2B/VisualBasic/等等)。|offset|length|1705611|一种检查你是否有足够的知识在安卓系统开发的方法是注册一个Android+(比如这一个)并检查任务。这种方法背后的逻辑是:既然Android开发是你真正的目标，你可以立即尝试一下。这样可以帮助你意识到你能做什么，你还需要学习什么。此外，您还可以抽出一些时间来学习Java技能。|1705612|祝你好运，选择最有效的方式！|entityMap|0|LINK|mutability|MUTABLE|url|http://code.tutsplus.com/search?button=&search%255Bkeywords%255D=learn%2Bjava%2Bfor%2Bandroid%2Bdevelopment&view=list|1|https://www.coursera.org/course/android%25E2%2580%258E^0|0|2D|2|0|0|13|3|1|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|T|8|@]|9|@$D|U|E|V|1|W]]|A|$]]|$1|F|3|G|5|6|7|X|8|@]|9|@$D|Y|E|Z|1|10]]|A|$]]|$1|H|3|I|5|6|7|11|8|@]|9|@]|A|$]]]|J|$K|$5|L|M|N|A|$O|P]]|Q|$5|L|M|N|A|$O|R]]]]

I decided to jump straight to Android and to learn Java as I go. Start is usually easy - you can get Android Developer Tools from the Android developers site, where you will also find some tutorials to help you make the first steps.

However, without proper Java knowledge, Android development soon becomes overwhelming (at least it did for me). Luckily, there are tutorials for those, who want to learn Java solely for Android development. You can find them <a href="http://code.tutsplus.com/search?button=&amp;search%5Bkeywords%5D=learn+java+for+android+development&amp;view=list" rel="nofollow">here</a> (they are designed for people who already know another language like C++/VisualBasic/etc.).

One way to check if you have enough knowledge to develop in Android is to sign up for an Android MOOC (like <a href="https://www.coursera.org/course/android%E2%80%8E" rel="nofollow">this one</a>) and check out the assignments. The logic behind this approach is: Since Android development is what you really aim at, you can give it a go immediately. This way will help you realise what you can do and what you still need to learn. Plus you can always take some time out to brush up your Java skills. 

Good luck picking the most effective for you way!

I am quite proficient in C and know some C++, but never touched Java. Recently I got an idea for an app which I think has potential, and I want to develop it. 

I am planning to go Android first, cause it doesn't require a mac/iPhone. 

So my question is: can I go straight to learning Android development, picking up the Java syntax as I go along and need it (after all I don't think it's much different from C/C++), or should I take a couple of weeks to learn the basics of Java first and then start with Android development?

Jump into Android or learn Java basics first?

我非常精通C，知道一些C++，但从未接触过Java。最近我想到了一个我认为有潜力的应用程序，我想开发它。我计划先使用Android，因为它不需要mac/iPhone。因此，我的问题是:我是否可以直接学习Android开发，在我需要它的时候学习Java语法(毕竟，我认为它与C/C++并没有太大的不同)，还是应该花几周的时间先学习Java的基础知识，然后从Android开发开始呢？
