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?

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.
Just wondering which mobile device should i target first for my application after a bit googling i found Android dev phone 1 and android developer phone 2 but does this device have or support Android 2.1 ? Or can i target some other device like motorola droid for my development and testing ? What would be the pros and cons in this situation?

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.

when I type % adb devices List of devices attached HT845GZ50600 offline
I am using: Ubuntu 9.04 (Jaunty)
Few things I tried:
1. I have changed the 50-android.rules file and reloaded the udev. [ as suggested by docs] 2. 51-android.rules ( if there was another 50 then this would have worked) and it worked for some users [ diff thread in the forum] .
2. I also killed adb server and restarted it.
3. It works on Windows, but I want to develop on Ubuntu ( and curious why it doesnt work).
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.
Is it possible to install J2ME applications on andriod device? I read somewhere that its not possible. are there any alternate ways (such as third party support) to run J2ME apps on android device.
View 2 Replies View RelatedI'm trying to make my application (compiled against 2.1) compatible with the 1.5 platform. I've handled all of the res/ folder issues, and have been able to run the app on all platforms without problems. I can run it fine on all emulators, and all devices/OS systems running 1.6 or higher. But on the only 1.5 device I have (HTC Hero), I get intermittent problems.
The only 1.5 device I have is an HTC Hero phone I got free at the Sprint developer conference a few months ago. When I test the app on that device, I have occasionally encountered a bug I've not seen anywhere, and can't find any information about.
I can install the application via the adb install command (although I get two messages about unknown commands), but after installing the app, the icon can disappear from the home screen, replaced either with a different icon or no icon.
When the app is launched in this state, rather than seeing my application name in the title bar, it reads "60.0dip". I don't use this value anywhere in my application.
I have never observed this problem on any other phone I've tested on (G1, myTouch, two Motorola Droids, Nexus One), but as I said I've only got one device running 1.5.
Just started developing apps and am having a small problem. I can test the apps on the emulator but I cannot test them on my physical android device. When I am asked to select a running device I get a device listed as: Serial Number/name:? AVD name: N/A Target: unknown etc,
It seems that my device is being picked up but not able to be used. When I try to run the app I get an "Must set android.target.avd" error.
Is there something I am missing?
I am using netbeans 6.7.1 on Ubuntu 9.10, everything up to date. I have a G2-Touch from T-mobile, if someone tells me where to find it, I will post any other needed information.
Apparently my app needs 2.5 MB (maybe because my photos need 2MB...) and then virtual device can't work with that much MB.
How can I make my virtual device support more than 2.5 MB to get my application working?
I ordered Le Pan II tablet yesterday.Today I found out that so far there are no ADB drivers released by manufacturer.Does it mean I will not be able to develop applications on this device at all? I do not mean developing applications that require root access (this tablet has not been rooted either but I am OK with this).

I got it from Orange, and as a result it's bundled with loads of applications I don't want e.g. a few demo games, orange maps...etc. How do I remove these. If I go to applications I can see the app there, but if I tap it, there is no option to delete
View 3 Replies View RelatedIt's not a huge deal, but it would be nice if I could clean up the app page and get rid of some of the crap I will never use and only have the apps I want in there.

It doesn't void your warranty

I realise there are a few threads about this, but I thought I would make a new one for my easier guide, and hopefully people will find it more easily as they won't have to scroll through pages of other threads to find an answer. I am now successfully running most apps from my SD Card now. I just thought I would make an easier guide as the others are fairly complex for noobs like me............
Just followed instructions on how to move apps to sd card on an unrooted device....all worked well, moved what i wanted to, but would now like to put phone back to default settings to install apps to phone memory.
I tried to open run command on my pc with phone connected and typed pm setInstallLocation 0.....but all that comes up is command is not recognized.
Is it possible to get the apps off of my incredible, that no longer has service, so I can install them on to my x? I have an older version of handcent on my incredible and I want to see if that version will work on my x, since the version in the market place does not.

View 1 Replies View RelatedI am looking generally in to Android development.
I keep seeing information on root however I am unclear how this relates to general android app development.
I understand that there is an emulator however when I get to actually test the software on a phone does that phone have to be a rooted device or is this only required if you wish to edit the core features of the os?
Finally are there are any development disadvantages to rooting the device such as that is no longer behaves like other android phones I may deploy too?

Can someone explain a couple of very simple concepts to me - I'm interested in mobile devices running android and how they are identified over networks. Some scenarios: Device is connected over WiFi - presumably the device has a standard IP address as with any host and can communicate with any other android host over TCP/IP (assuming it knows the participating device's IP? device is connected over bluetooth - how are devices identified in this case? device is connected over mobile operator's network - this is the one I'm interested in and confused by - is there anyway for two or more devices to discover each other and communicate via the mobile operator's network? How does a device communicate with a backend server in this scenario? In other words, how do apps and devices communicate when not connected to a WiFi network?

Or is there any other apis which can be used for implementation of multiplayer in game ?
I've studied several Android books in 2009 and have fiddled with SDK 1.0 with a couple of test projects; then I moved to another side project with different technologies and I have not followed the updates of the SDK in term of cool new features. Do you mind to give a brief recap of what I've missed since SDK 1.0?
View 1 Replies View Related1- I am an iphone application developer, all iphones have very similar Operating systems, and the size and everything is the same, so I don't need to create applications specific for each iphone.
But with android there are different phones, different sizes, So How can i possibly know that my app works, and looks fine on all these devices
2- I don't already own an android but i completed my first application using the simulator. Which android phone do u suggest for testing? I am an AT&T user and i use an iphone. Can i simply insert my sim-card in the new android to be able to test my app on the device?
With the latest SDK release, and the ability to download separate platforms releases into the SDK, the hardware resources required to develop for Android have increased significantly. Assuming that the developer targets all currently available seven platforms - that could take your dev machine to its knees. Taken alone the 'Android SDK Content Loader' takes nearly two minutes on a dual-core machine with 2GB memory.
As the title suggest the reason for creating this wiki is for everyone to list their development hardware configurations, and thus determine what is a well-suited machine for Android development.
The secondary reason for the wiki is that I'm trying to get my employer to provide me with a decent machine for development as I'm currently forced to work on a nearly 4 year old randomly-built machine, and expected to deliver great results. However, the reality is that my system keeps running out of memory, and I can hardly get a chance to write a few lines of code in between the numerous crashes.
Is Ubunto 9.04 compatible with development in Android? Before i ugrade, deploy on device was normal. Now, using 9.04, doesn't recognize it using "adb devices". This below is already set on my ubuntu: 1. Login as root and create this file: /etc/udev/rules.d/50- android. rules.
For Gusty/Hardy, edit the file to read: SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"
For Dapper, edit the file to read: SUBSYSTEM=="usb_device", SYSFS{idVendor}=="0bb4", MODE="0666" 2. Now execute: chmod a+rx /etc/udev/rules.d/50-android.rules
