I am currently interested in learning more about developing android applications. I've made hello world for android but that is pretty much it.Has anyone read 'Sams Teach Yourself Android Application Development in 24 Hours'? If so would you recommend it? If not, could you point me towards some other resources?

I've been teaching myself Java over the last few weeks. I already know several OOP languages, so i was not too complicated. I have just learned some basic Swing and I now want to develop a simple app. How do I use Android-style Swing and custom graphics to do this?
View 4 Replies View RelatedI will admit - I've never had a smart phone. Never. I was going to get one last year, but waited b/c I heard 2010 was 'the year of the smart phone' - and I'm glad I waited.Though I'd have to see it in person to know for sure, but I'm almost positive that DroidX will be my first smartphone. I'm VERY excited, but I want to make sure that I'm educated enough to use it for all it's worth (ie: my mom has had every iphone, but just leared to text message last month).Is there some place/book/thread/site that I can study which would tell me about smartphones from the very most basic all the way to the more advanced? I'm a smart girl, but I have to start somewhere!

View 3 Replies View RelatedI tend to believe that developing mobile applications in an enterprise environment is best suited by developing intranet web applications. That said I have been asked to think about whether there are specific enterprise applications that could only be accomplished or would be more successful as native applications. I am curious as to what the Stack Overflow community thinks.
View 6 Replies View RelatedFirst and foremost, are there many android developers here? Is this a good place for Android related discussions?I seem to be missing a rather large concept of Android development. The gist is I am struggling understanding how to tie an application together. I'm not sure how to explain it, so I thought I would do my best with an example from the Android ApiDemo... assuming you are familiar with it.
Inside the com.example.android.apis.view namespace of the ApiDemo, there is a class called Animation3.java.Animation3 inherits the activity class and there is some code inside to display animation.I can't find a reference to the class (Animation3) anywhere in the demo code (except for its definition obviously). The only mention I found is in the manifest xml file. So how the heck does this activity get started? Don't we need to create an instance of the class somewhere and fire off a method to start it? I don't understand how to generate the code that ultimately glues this class to the rest of the application.Additionally, what about other classes like views or viewgroups? How do I generate code outside the class that initiates/starts/uses/calls (insert proper term) the class.I would appreciate any code examples as well as any concept explanation or reference documents. So far I've read pages and pages on activities and views but I'm really struggling how to tie things together.
I normally frequent the Nexus One forum, but have had to crawl my way out from there to come ask the wider Android community a question.
I'm about to apply for a mobile application development role and was wondering if any of you guys knew an approximate number of Android users (or point me in the direction of somewhere that might have the info). I was about to write something along the lines of the Android market allowing developers to easily (hum, that's an opinion there! ) share their creations with <insert amount here> Android users around the world, but realized I had no idea.
I recently ordered a Droid Incredible and starting looking through the Google documentation for the Android, but I learn better by reading a book. So I need some programming book recommendations for Androids.

Right now if I am using my phone for browsing, video, etc. it will run the battery from full charge to dead in just under 4 hours. If I just leave the phone turned on but with no apps running (standby) it runs out of power in roughly 48 hours. Is this the battery life I should expect from this phone?

View 25 Replies View RelatedI am developing droid apps with eclipse (new to both) and have a basic Layout question. When using the layout tab (rather than the coding tab) in my main.xml, I am trying to create a home screen for when my app opens.
There is going to be the logo at the top center, then 3 simple buttons below, all centered. How do I go about formatting the Logo so it maintains a size relative to the person's screen size, and stays in the center?
I don't want to write sloppy code to where my program looks fine (UI wise) on my screen and is poorly formatted on other's screens. Also, is there good documentation explaining all of the Property values in the layout view?
I recently installed a custom ROM in my phone.
What I noticed is that the problem is either that my phone drivers can't be installed for some reason (I have a SGS being treated as a Google Nexus S), or I just can't implement applications.I mean that when I try to build an application on Eclipse, my phone is not recognized, like I don't have it plugged in.
A lot of open source libraries that aid in Android application development have sprung up with time. IMO looking at source code of good projects helps learn the system better, faster and not to mention reduces development time. Is there a recommended list of such projects or if not, can we build such a list? I think it will really be useful to other developers.

Google Nexus One / Htc Droid Incredible / Htc Evo 4G / Motorola Droid ?I have to develop on Android 2.1 and 2.2. All those devices will have the update I think.
For example, I want to parse the string below:
Tue Sep 28 18:02:24 GMT+08:00 2010
And I use the pattern for the SimpleDateFormat:
new SimpleDateFormat("EEE MMM dd HH:mm:ss zzzzzzzzz yyyy");

View 6 Replies View RelatedIt is a common thing to add a color name and a color RGB value in a config xml file for developing an Android application. It is boring sometimes for example, when I want to add color pink, I had to find some tool to show me what the exact RGB value for it and then fill it in that xml file. Is there a common color file including all common colors for Android application development? I am wondering is there any predefined color file?
View 1 Replies View RelatedI just bought a second hand Samsung Galaxy Portal, and it's a great phone and works fine, but the battery is dead 12 hours after a full charge. I had a task killer installed at first but I removed it after reading about how it drains the battery, so I'm wondering what else it could be? I know it might just be an old battery that's lost it's will to hold charge, but what can I check on the phone before I have to splash out on a battery or take the phone back? I know it has some decent tools for monitoring battery usage so what should I be looking for?

View 5 Replies View RelatedWhen I am developing for Android and repeatedly running and/or debugging an Android app in the emulator then about every two hours or so I get an Out-of-memory exception, occasionally also an out-of - resources- or out-of-GWT-handles exception. At that point one can only stop and restart eclipse. Apparently the ADK must be doing something wrong, because I have been developing with Eclipse now for 5+ years and I normally never see this. ADT is a really the exception here. Is there any setting or patch that helps top avoid this? I have already given it more heap space (750M) to stretch the time between these hickups a bit, but that approach isn't really sustainable.
This is using Eclipse 3.5 (Galileo) and the Android SDK r06 running a FroYo AVD.
I am a new comer, previous owner of the iPhone 3G and the iPhone 3GS. I acquired an ADP1 through our research group at school since we were developing an application for Android (WifiMapper, helps you remember APs you've connected to by mapping them). Regardless, my iPhone 3GS from near battery death to full charge took maybe an hour and a half in USB, let alone a wall charger pushing a guaranteed hour and a half. However, I've found that my ADP1 takes at LEAST 6 hours to charge from around 5% charge. That seems like a long time to me... for instance, today it was at 12%, and I charged it for 3 and a half hours and it only went up to 52%.
View 9 Replies View RelatedIn December, there were new terms for the Market. A big note was "You authorize Google to give the buyer a full refund of the Product price if the buyer requests the refund within 48 hours after purchase." It still seems that all references to the refund policy still state 24 hours. http://market.android.com/support/bin/answer.py?hl=en&answer=134336. So is it 48 or 24 hours officially? Is the 48 hours in the agreement just because the 24 hours never seemed to be a hard deadline. I noticed users refunding around 30 hours in the past.
