Can anyone recommend any books or resources for learning smart phone architecture (specifically iphone or droid)? I am looking to learn and get into smart phone development, having been doing desktop development for a few years now.

I'm scoping a new software project and haven't had much experience with software development. This is a multipart question.
What are some recommended books for web application architecture?
We are basically looking to develop several front end applications (mobile and websites) that can query a central application pool that'll hit our backend database to retrieve the data. Is there a name for this kind of architecture?

Good book for beginning android development
The best book for programming in Android
The "best/easy to understand" "resource/tutorials/guides/book" wins the answer!
I'm really trying not be subjective here. Most guides I came up with on forums, etc., date back to 2007/2008 so I guess I want something more recent. (Some of them are reeeeeally outdated).
I have a problem on my Asus ME301T tablet with the Play Books app (I'm running android 4.2). Regular text based books work just fine, however, comic books show as blank pages. Sometimes it will load a few pages if I rotate the screen a few times.
I've tried to reinstall the app and redownload the comics without luck. It works fine on my Samsung i9000 running android 4.3.
What has people's experience been in learning Android? I'd be interested in how long it takes to get to the point where you're writing your first app, and how the experience compares to learning some other programming API. I know several professional programmers who have tried to learn Android and failed. Is it inherently more difficult or larger than you might expect? But there's a survey here http://www.infoq.com/news/2010/07/Mobile-Survey that claims Android has the shortest learning curve of all smartphone platforms. I wonder how the survey guys could have got such a perverse and unlikely result. I have my own views and observations on this, which I'll mention as a dialog develops. I don't want to bias the discussion with my perspective at this point.

Anyway, I thought since I'm currently trying to learn Spanish that it'd be great if there was a nice application that could help.
So does anybody know of or have any personal experience using any language learning applications that they could recommend please?
This may have been asked but I can't find what I am looking for in search.Anyway, we have 2 droid phones, we want to use them in the house in a hands-free phone mode, with some sort of external speakers.I found some blueant speakers for cars, and was recommended this one S1 Sun Visor model.
View 25 Replies View RelatedI would like to know, what limitations there are for how far one can go in terms of replacing UI components of current touch screen smart phones, in particular iPhone, Blackberry and android based phones.What I would like to do is create a custom UI for dialing out and incoming calls.
I have some experience with Blackberry development. The theme builder for it, can be used to customize certain items on the incoming call screen, but it doesn't look like that you can increase the size of answer button. I know Blackberry also gives you access to all the phone APIs, but I'm not sure that you can create your own UI that can gain preference over the Blackberry incoming call screen. And if you try to customize the incoming call screen by adding any buttons to it, they would be rendered as pictures.
I could possibly design a complete UI for android, since different manufactures have different UI for android based phones. Can I do what I want to do using iPhone, Blackberry or android? Or any other phone for that matter? I am guessing may be for Nokia phones using Qt, but I prefer the 3 platforms I listed.
getting a dev board for use as a mini pc. Wondering can you compile android on arm hardware or only on x86 hardware. If you can compile android on arm I will get a high end quad core dev board, if not will just go for a mid range dual core board. Thought it would be a fun project to have an auto android builder along with file and print server. Yes I know it will be slow to compile.
View 2 Replies View Relatedi'm currently trying to specifically target ARMv7 custom hardware and I'm facing issues when trying to install the APK. When I try doing "adb install app.apk" Logcat informs me that: W/PackageManager( 1062): Native ABI mismatch from package file And does not install the APK. With searching I was able to trace down that the problem might have something to do with the architectures not matching on the APK and the platform. Is this it? How does the PackageManager find out the architecture from the APK file? I'm guessing it's not trying to execute the binary or anything, it just checks the files meta data? If so, is there a place in the APK where this information is located? Or am I completely hitting blank here and I should look somewhere else?

How do you group classes together, what layers do you have etc.? I'm just starting Androi dev (an internet based app that must respond to incoming notifications) and have no real feel for the structure I'm aiming at.
View 2 Replies View RelatedI'm by FAR not what you'd call a techie, and I'm totally new to the 'smart phone". I just bought a Motorola Droid. I'm still trying to figure this thing out. The one thing I'm kind of not liking is... With my old LG Dare, I used VZ Navigator for my GPS. That phone was a touch screen, but when I would use the GPS to find where I was going, I could lock the screen, and it would stay lit, and the program would continue to run. But if I bumped the screen with my finger, I wouldn't be thrown out of the program, or into another one.
I'm finding that with my new Droid (which uses Google maps) that when I'm using the GPS on that, I will occasionally bump the screen, and then I have to try to navigate my way back to the GPS. So if anyone knows of an app that allows me to keep my screen fully lit and the program working, BUT still locks the screen, could you please let me know?
Will the smart phone ever take the place of the home computer as we know it ie desktop/laptop.
With most service providers now doing unlimited internet and our phones capable of anything ie email, text, facebook, twitter, sell and buy stuff on ebay, watching movies, TV the list goes on and on. Why do we need our home computers ?
I believe the home computer is on its way out, yes we will need the computer in industry, banks, stock control etc ie for business use but for the home market its doomed.
-how many phone books with contacts can you have?
-i can't see any obvious way of adding a second phone book with contacts. Am I missing something?
-where is the phone book with your contacts stored?
-can you copy this phone book file, complete with all of its contacts, photos etc.to your external sd card? When you export your contacts is this what you are doing?
Is there a good way for me to use my Droid to read books? I presently use an IPOD touch and the kindle reader app but I was thinking on selling it. Do any of you use the Droid as a book reader? If so what app do you use and where do you order books that can be used with that apps reader?
Also I know you can play videos on the Droid. If I wanted to put my own ripped movies on the Droid can I do that? Does the droid recognize XVID or Mpeg? What movie player would I need to use? I have a whole bunch of tv dvd's that I want to rip and watch on the train.
I used the recovery mode first time - it worked, second time playing with NoBloat - it gets stuck in boot screen.I can go to the recovery mode menu, both chinese and english, can do a full clear cache, data, format, but phone still won't boot.
I can use ADB shell, but Smart phone flash tool does not recognize phone, MTK droid tool recognizes it, but I can't backup it.
Does the Live Wallpaper run in the same process as the Launcher? I looked through the Launcher code and cannot really figure out where the wallpaper "layer" fits in. I am looking at this with the lens of memory consumption and safeguards that the Launcher has in place against a bloated Live Wallpaper.

View 3 Replies View RelatedIn my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:
InputStream is = Resources.getSystem().openRawResource(resourceId)
However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?
Or, is there a way for me in Java to extract all property values from the R.drawable static class?
I know you are required to have a data plan for a smart phone. But does that only apply to those on 2 year contracts?
I have an old D2 that my wife wants to use. She currently uses a dumb phone. She doesn't want a data plan, doesn't want the smart phone features. She just wants to use it for calling & texting.
Is there any way at all that can happen? Or does any smart phone, even older ones or unlocked ones, need a data plan?

View 20 Replies View RelatedWell, this is my first post and as the title states i finally took the step to buy a smart phone and the old Nokia 6120 classic is headed for the drawer.I was tossing up between the Iphone and the HTC Desire. Not really wanting to be an Isheep and after reading all the good reviews of the Desire on the net i decided to go with it. First up i'll address the main point i was worried about..... battery life.
All the people saying they get less than a day with theirs made me worry. But after thinking about my usage compared to others i decided it would hopefully be fine. After getting mine about 5 days ago and charging it up overnight i can say that i didn't really have anything to worry about got through my first day (Friday) with a couple of phone calls, played around with it for half an hour at lunchtime, then probably another hour or two of constant use when i got home playing with the settings, widgets etc. It then continued trucking on till the following day (Saturday) where i played around for another hour or so in the morning until about 11am when it started to get low. That was when the battery warning came up on the screen. So i got about 30 hours out of it on the first charge and by the sounds of some other posts this will get a bit better. Without all the time messing around with the new toy and the battery settling in id say i'll be getting at least 2 days without a charge in the future. I realize other people use theirs a whole lot more at work but i have a radio in my car i listen to on the way to work so no mp3 needed and a phone in the office i use, but if your like me and just a casual user to make a few calls and send a few texts, check the weather out and surf the net a bit it will be fine. I realize that im not using it to its full potential, but thats fine with me. Code...
Looking for possibly undeleting a few pictures I took yesterday on my Galaxy 4S smart phone.
I know the directory where I need to do the undeleting but none of the un-delete programs I have gathered will show anything that makes sense when it comes to the phone.
When i plug in the phone to my computer I get 2 directories..
Phone and Card (card is my 32gb micro sd)
The pictures I would need to try undeleting would be in the following directory: ComputerSCH-I545PhoneDCIMCamera
I cannot find a way to have any undelete program scan that portion to recover files... I have even taken out the micro sd card which did not matter ..
I currently don't have a slow smartphone but when I had my original Droid it would really slow down until I put a new or updated rom on it. Even if I rebooted it it would still be slow. I now have the Droid Bionic and it's really fast but will it someday get slow? I guess I don't understand the smartphone technology very well, yet. Is there or will there be some sort of software that you can run that will speed it back up?

View 4 Replies View RelatedThe code I am trying to implement includes a service and an application. When the application is first launched, it starts the service using the
startService(svc_name) call. Here svc name is an intent pointing to the class that runs the service.

View 1 Replies View RelatedSo, today as I was rushing to get on the train after school I needed to make a phone call that would determine what train I would take. Of course, since it was time sensitive my droid decided not to make our receive calls. I would dial the number and hear nothing but silence even tho the call had connected. The party on the other end was getting the call but we could not hear each other.only silence. I had to reboot twice at which point I had a number of voice mails from the person i was calling trying to see what was happening. My phone is not rooted and I just have some basic popular apps. Is this just an occasional smart phone glitch or have others had this happen?
