Has anyone managed to develop Android Applications using Eclipse on the Windows platform. I understand the ADB needs to recognise specific models of phone and wondered if the Tattoo is supported.

I've watched many of the Google IO talks and one that I'm trying to reproduce is "Developing Android REST client applications"[1]. In this talk Virgil suggests you should not execute your RESTful queries inside a Thread/AsyncTask spawned from your Activity (which I had been doing), instead you should use a more complex architecture that uses a combination of a ContentProvider and a Service. From what I understood the reason for this design was so your data was more persistent between app restarts, and so your queries don't disappear if your Activity starts/stops (e.g on a screen rotation). I buy into both those reasons hence I'm trying to implement this. On the slides[2] page 45 We have an Activity calling a ContentProvider. Now the ContentProvider checks its local database, if the content is not there it sends an Intent to a service which fetches the content, inserts it into the ContentProvider, then the ContentProvider calls back to the Activity (with a ContentObserver) and the Activity can carry on. The question I have is how is this callback setup. The ContentProvider exposes simple methods, query, insert, update, delete which don't seem easy to adapt to a callback interface. It could be implemented by a Cursor which is designed to block, but that could be problematic as you don't' want to block your UI Thread. I'd appreciate if anyone could make this clearer to me, or show me some code. I'm hoping the Twitter app will be open sourced soon which apparently uses this architecture.

Can anyone show me a code example? Either the code for "Option A: Use a Service API" or "Option B: Use the ContentProvider API"
View 4 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?
I'm developing an application that would need to persist data locally in Android devices. I'm aware that Android provides two packages for database persistence, the normal "java.sql" and the "android.database.sqlite"? Which one is used more for persistence? I suppose that "android.database.sqlite" is the implementation of "java.sql",
View 1 Replies View RelatedWe are trying to use a shared server (Ubuntu 9.10 64-bit) to develop Android applications. The thought is that a number of developers should use the shared server for development. We have overcome some obstacles such as setting the base port for DDMS. So it is possible to run multiple emulators and multiple instances of Eclipse. But we run into problems when trying to debug applications from Eclipse. It seems as though all emulators are trying to connect to the same Eclipse instance when debugging.
View 1 Replies View RelatedI've already written some small Android Applications, most of them in one Activity and nearly no data that should be persistent on the device.
Now I'm writing an application that needs more Activities and I'm a bit puzzled about how to organize all this. My app will download some data parse it show it to the user and then show other activities depending on the data and the user interaction. Some of that data could be cached, some of it has to be downloaded every time. Some of that data should not be downloaded freshly at the moment the orientation changes, but it should on the moment the activity is created...
Another thing I'm confused about are things like a httpClient. I now for example create a new httpclient for every activity, the same thing for locationlisteners.
Are there books, a blogs or documentations with patterns, examples and advice on organizing larger apps build on android? Everything I found until now are get startet tutorials leaving me alone after 60 lines of code...

View 2 Replies View RelatedFirst of all, I just want to say I am a software developer, but I am not an Android developer. However I usually walk around and think on stuff. AndI've been recently thinking all the news concerning how fragmented Android is getting, with different Android versions and tweaks by different phone manufacturers, and then for developers you have different size formats. An example would be that HTC Tattoo might not be able to run everything that another phone might run, due to different screen formats, etc. And now the Android tablets are coming with different Android versions and different screen sizes, all from 5" to 11". Will this make developing Android applications harder? Apple has it safe here since they manufacturer all devices that run the iPhone OS: the pods, phones and now the pad so they can easily control and make sure not to loose any customers by introducing a new device. When Apple introduced iPad they had to make sure that all the old iPhone applications would work on the iPad. They solved that neatly by saying that iPhone applications will simply be stretched out to the double size and it would fit on the iPad. Unfortunately Android does not have the same luxury to do this. As I said, I am not an Android developer. Just a curious software developer For you guys who work actively in the Android community, does Google have a solution for this? Will you be able to run phone applications on the tablets? Is there a bridge between the devices? Are there any standardizations or will Android development become even more fragmented? you are subscribed to the Google Groups "Android Developers" group.

View 2 Replies View Relatedmy newly bought Tattoo became unbootable a few days ago.It worked perfectly fine two days ago, then it started to randomly reboot itself, but after that, it became completely unbootable, as in, it was stuck at the "TATTOO" screen. The phone internals are completely untouched, no custom images, not rooted, no nothing, it's factory fresh.The battery is full too, and I didn't install anything that could possibly have corrupted the bootloader (or whatever is failing to load).I already tried to wipe the user data _TWICE_ (using HOME + BACK + POWER) with no success. I'm also perfectly able to get into HBOOT (using VOLDOWN + MENU + POWER), and connect via usb (using "FASTBOOT USB" from HBOOT). However, I can't completely wipe the cache with fastboot.exe from the android-sdk, since it doesn't allow it: "erasing 'cache'... FAILED (remote: not allow)".

Are there some applications that can help me getting a human view of content resolvers values and/or SQLite databases?
Is there any way (e.g. with the command-line) I can upload an APK to an android phone wirelessly (wifi or Bluetooth) and launch it on the phone from a desktop machine?
I can do this things with abd from the command line when a USB cable is attached but I'd like to know if I can do this without having to mess around with cables.
I am a newcomer to android development. I created a image puzzle app named "Sexy Image Puzzle" It is a simple jigsaw puzzle. As I have just started developing for android, I didn't buy the dev phone yet. I tested the application in Emulator. I was planning to create similar puzzles for Cars too. But the app has too less downloads so far. Could anyone use this app and let me know, what is going wrong? It is a free application, so there is no payment involved. I just want to know some feedbacks, what is going wrong. This is a small help, I need from you guys, till the time I buy my dev phone (probably starting september)

View 2 Replies View RelatedI'm new to Android having got my HTC Tattoo during the week.I'm wondering if there is any way to get Android 2 (Eclair) onto my Tattoo? I've googled for it but there's only instructions for the Hero.I don't care if its a vanilla ROM without Sense UI. I'm just looking for an update to help improve battery life and bluetooth functionality (plus I like to have all the latest versions of things :-)I emailed HTC about it and they said they couldn't confirm if the Tattoo was getting the update (which probably means it won't...)
Also, I'd rather not use a buggy beta ROM .I know people managed to get a V2 ROM onto the G1 by rooting but I presume it's differen for the Tattoo because the different screen size, addition of FM radio etc.

And over all why it is not visible in the market and how to solve this? Need to contact Google?

View 3 Replies View RelatedMore or less as it says on the tin. Before I even contemplate downloading the SDK, I was wondering if there was any way of testing Android apps that I'd write without an Android phone available to me? I'm unsure as to whether or not the tools that come with the SDK come with an emulator like VS does for Windows Mobile.Sorry if this is a stupid question, but maybe I'm searching for the wrong thing.Edit I don't suppose there's anything that'll let me write widgets on/for an emulated version of the interface HTC use on the Hero/G2 either is there? Not that it would matter that much.
