Android :: Phone Applications Development
Sep 6, 2010
I've been developing applications for a long time now, but now I want to jump into Phone applications development. There are four main candidates:
Nokia's Symbian
Apple's iPhone
Google's Android
Microsoft Windows Mobile Phone
considering documentation, market, samples and availabilty of emulators, I'm not a millionaire so I can't buy it unless I know it would mean profits!
I don't have much preferences as for languages, but to stay within C# would be nice, however I've been thru Assembler for a long time, so it's hard to scare me.

I'm looking to get a device (phone, tablet, etc.) for developing Android applications. I know I can use the emulator to get me started, but I feel like that will only get me so far along. I'm looking for something reasonably priced, and I don't want a phone contract, data plan, etc. Anyone have any suggestions?

If anybody is creating multi-touch apps for Android, you may have noticed the MotionEvent class is getting more and more complicated over time. Additionally you may have discovered your code has different quirky behavior on different devices (e.g. on Synaptics devices, touch-down / touch-up can cause sudden jumps in pointer position before the down/up event is received).
I have written a class to simplify the process of writing multi-touch applications for Android, and just updated it to Android 2.2 (and to handle 3+ touch points on true 2D multi-touch sensors, as present on the HTC Incredible and HTC EVO 4G), and moved the project to Google Code hosting:
http://code.google.com/p/android-multitouch-controller/
There are numerous advantages to using this controller over trying to reinvent the wheel yourself, including simplicity and automatic device- space / object-space coordinate conversion for pinch-zoom. This also correctly centers the zoom of a pinch operation on the center of the pinch rather than the center of the screen, and supports simultaneous pinch-and-drag for more realistic pinching.

I have an HTC dev phone but from what I can see on the HTC dev site (http://developer.htc.com/adp.html#overview) the latest version they list for flashing is 1.6. Anyone has any experience with these phones and whether a later (2.1 or 2.2) image can be found and flashed on them?

I am writing an application that initially will be developed as web (probably Silverlight) and Android application. I found on Android website that SQLite is supported, but I plan to release the same app for Windows Mobile, Palm Web OS and iPhone as well.Could you please advice me on which database would be the best to work with for all platforms?EDIT:Maybe I should add that I would want all applications (mobile/desktop) to connect to a main server when internet connection is detected and synchronize all data that's changed.

I'm wondering if there is something like 9-patch in Android, but for web development? Disclosure: I have no idea about web development at all, but I was curious to know if it exists. And a simple web search with the term 9-patch didn't bring up any related results, so I figured it has either another term or it doesn't exist or is not used widely enough.

I would like to start doing some Android development, and would like a cheap device to deploy apps to, just for testing and demo purposes. Is it possible to deploy apps to, for instance, an Archos 28? I don't know much about Android development yet, and haven't found a good answer to this question elsewhere.

I've been using my G1 under Windows 7 64-bit and Eclipse just fine.
However, when using my new Nexus One instead - and making sure that 'Use Debugging' is enabled - the Nexus One is not recognized and debugging on this phone is not possible.
Usig the Nexus One as a removable-drive (by mounting it) works fine.
How can I start using the Nexus one as a development device (on Eclipse)?

I'm just getting started with Android app development on a Mac, and I keep getting a NullPointerException everytime I go into Strings.xml to edit it. Here's the steps I followed - The project compiles and runs fine, but if I add even a single character to Strings.xml, a popup comes up that says - "An error has occured. Please see the log for details. An error has occured. Please see the log for details." When I click details, all I see is - "An error has occurred. See error log for more details. java.lang.NullPointerException" Anything I'm missing completely? Code...

I'm a mobile media product developer at a major media company in New York City, and we are looking for a vendor with experience in Android, web apps, and mobile in general. I understand Android is new, but if you've got something out there to see already, that would really help. Please reply with a brief description of your Android experience and a link or a word about yourself and your company.

Can I use any Android Phone for app development? Here in the Philippines, there are many available mobile phones with Android installed. But I want to buy the cheapest phone available (which I think is Samsung i5500 Galaxy 5).

I know many developers ask about the best Android phone for development, but my question is almost opposite: What is the least expensive Android phone that I can get away with TTS (text-to-speech) and ASR (automated-speech-recognition) software development?
To further clarify my question:
Do all Android phones support
TTS and ASR?
Do all Android OS versions
support TTS and ASR?
If the answer to either of the above
is 'No', then which brand/model will
provide me with TTS and ASR functionality
while minimizing out-of-pocket
expense?

I am an iPhone user but looking into developing android apps. As a web developer I feel apps are something I need to be involved in. My next step is to purchase an android power mobile for testing etc... My budget is low as I will be buying this phone aswel as my current iPhone contract so a max of 20/mo for a contract phone (my gt will use the phone and messages etc...) What budget android is best for development?
I have been offered the samsung galaxy portal and the HTC wildfire for 20/month on '3'.
I've been told to go with htc as it was deeloped for android rather than samsungs phone which just has android on it.
From an app developers point of view, what phone shall I choose?

I want to get into trying my hand at Android software development. What is the developer phone in terms of ease of development, debugging features etc. that's out there? It should also be a good phone too, as I'd want to use it as my primary phone.

If I purchase an app with my current phone, and then I upgrade to a different phone in a few months, is there a way to take the apps with me? I have searched and can't find anything definitive. The ideal thing is if Google is storing my application history with my Google account somewhere, but I don't see where it would be.

My Droid 1 has officially died and I'm looking at purchasing a Droid X on eBay. When I get the new phone and sign in with my Google account do I have to repay for applications or will I be able to download for free?

Ok here's my problem. I'm very new to the AndroidSDK. I've ran sdparted to convert my ext3 to ext4 and just tonight I learned how to open the emulator.I used the Android development site to learn how to do all this. I ran this: emulator -avd my_android1.6 -t 2 The emulator opened up but, it looks nothing like my phone nor does it have any of the apps that my Magic 32B has. This is my question. I'd like to be able to run an application that is currently installed on my phone on my computer to enter in a bunch of data into that application to use on my phone. It's much easier to type everything out on my computer than using the keyboard on my phone. Is this possible to do with the emulator and if I can how? I'm rooted and using Cyanogen 4.2.5.

I have a Droid X running 2.2. I'm trying to understand the advantages of storing apps on the SD Card vs Phone storage. Since the Droid X comes with 8GB of phone storage, I've got lots of room there.What would be some reasoning behind moving apps to the SD card? I see lots of people get excited when a favorite app adds SD card support, but why exactly? Maybe it's more of an advantage for phones with less phone storage? Also, how come in manage applications, it says that the app takes up way less space when it's on the SD Card? For example, I just installed Angry Birds and it put itself on the SD Card when it installed. It showed 1.83MB in size. When I moved it to the SD Card, it showed 14.06MB.

I am planning to purchase a DroidX on launch day and am switching from a BB Storm2. There are a few apps that I love on my Storm2 that I would like to have on the new phone. Wondering if you guys (and gals) can point me towards similar apps for the Android platform. 1. BerryBuzz - Customizes LED light for different notifications (I.E. can set light to Orange for SMS, Disco light for missed calls, etc.) 2. BerryWeather - Awesome weather app 3. Later Dude - Can set a reminder (calendar, task, call, e-mail, etc.) based on an incoming message/phone call 4. Pocket Informant - Great PIM app.

If you are developing Android application, you will encounter such a id naming in xml files of view and layouts :
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/new_game"
android:icon="@drawable/ic_new_game"
android:title="@string/new_game" />
<item android:id="@+id/quit"
android:icon="@drawable/ic_quit"
android:title="@string/quit" />
</menu>
and I am really wondering why such naming is applied to ids. It is because of Linux? What kinda meaning this naming --@+id/...--has? When I am looking at android:icon attribute I can interpret that it means ic_new_game is located under drawable folder and @ means "located at" or I just assume that. But naming id attributes are kinda different because they also have + sign. Can somebody help me understand this convention?

I am trying to figure out some way to determine the current background on a phone and then set that background as my own in my application to create a seamless transition between my application and the phone. However I haven't been able to find any functions for this at Androids SDK site. Setting android:theme="@style/Theme.NoBackground" inside my Manifest almost does what I want, but it still has the icons in the background.

In my haste and excitement to try out my phone I downloaded loads of apps from Android Market and didn't really pay any attention to the warning screen that shows you which parts of your phone the app needs access to. Is there a way to check up on this after the app has been installed? What I would like to be able to do is go through each application and see what parts of the phone is needs access to and uninstall it if I feel that it shouldn't need access to various items.
