How this stuff works ? - General Questions and Answers

Hi All,
I'm new to the android and I'm wondering how applications which are also kind of social web based apps works and how do you approach developing something like that.
For instance zedge.net which is wallpapers, ringtones application / website. On the one end you have application on your android but on the other end you have website with your own account synch. with your android etc.
I'm just wondering if there are any supporting libraries / environments allowing one developer think of developing similar solutions like zedge.net. Not necessary exact the same but with similar android application (client) and website (server) architecture ?
Any tips much appreciated.
thanks

Cross Platform App-Dvelopment

Hey there,
I want to write an App which I want to distribute to different mobile Os. I'd be glad if it worked on iPhone, Windows Mobile, Symbian, Android and if possible otheres.
Now I'm looking for some technology I can use:
What would you recommend? Java, Flash, Javascript-based?
What I need is:
- app-downloadable, so it doesn't require an internet flat using it
- some api to have access to cell id and / or gps for phone tracking
- very easy cross platform publishing without much platform dependant code
I do have good Java knowledge and do code Actionscript 3 since some years. I already found some solutions for cross-platform development, but if there's anybody here with experiance I'd gladly hear some opinions.
I'm anticipating your replies

Android as an OS for non-phone devices

Hello,
First off, apologies if I have posted this in the incorrect forum.
The company I work for is looking to update one of it's product lines and has been toying with the idea of using Android as a development platform. Up until now the philosophy has always been to develop simple, bespoke embedded software that provides only the functionality that is needed at the time. The device itself will be a medical device, and as such will have no telephony requirements (and associated things like contacts, calander and the large majority of the pre-installed Android apps).
I have read, and understand it is possible to re-compile Android from source and remove all of these non-required functionality. My question is really if that is worth doing? i.e. stripping out all un-needed applications that get build into a stock ROM. Or would it be a more efficient to use some form of OTS embedded Linux platform?
Something in Android 4.0 that does seem to be useful is the support for Bluetooth HDP.
Kind Regards,
Simon
Well there are other devices that aren't phones that use Android. Take the motoactv for example. It's a fitness watch that runs a stripped version of Android, but it's still Android and applications can still be programmed and installed to it.

[Q] Communication between two different apps on different devices

Hi,
I have some doubts and do not know how to do, maybe you can help me.
so, I need to communicate between two different android apps on different devices.
Case study: i have tablet1 with app1 and tablet2 with app2 on a local network. I need app1 on tablet1 send and receive data to/from app2 on tablet2. So its a client/server communication (or better, i need many clients to one server).
There is a mechanism AIDL but only works different apps on same device, but i need on different devices. I have done some examples of services and messengers handler but without success. Applications must be version 4.0 and android app ( I say this because there is a NSD mechanism that discover services of other devices / apps android in local networks, but the minimum version is 4.1 and I already have several customers with tablet v4.0. I know it is possible but also do not want to install a web server on a tablet ( like a KWS or PAW server and others) ).
The documentation and examples that i use are google android site, like trainning, guide, references and others.
Thanks in advance for any tips.

[Q] Newbie: simplest way to make Phone apps Android TV compatible

Hi - I'm a newbie and frankly knows next to nothing about Android app development. There are lots of great apps out there that would be great to use on the big screen via Android TV (the only device out there now is the Nexus Player), but unusable on Nexus Player because they requires either gesture or mouse. This leads me to think that there must be a relatively easy way to take the APK and update the code so that I can use the d-pad remote for the Nexus Player.
Can anyone point me the way?
Thanks!

Manipulating the UI of existing native applications at runtime

Hello guys and girls! I would like to personalize some UIs of the applications I have already installed in my Android (not all of them, just a few ones). E.g. Using the same fonts, colors, etc. I know this sounds weird but I'm not thinking in creating an app for others but me, so it is not a problem if I have to root my phone or have it in debug mode. Any clue?
PS: I already saw some answers suggesting to decompress/compress the apk, but I don't want to modify the applications' sources, just injecting some style (as Stylish extension do it for Web applications) at runtime.
Thanks in advance for any clue! I'm a newbie and I think I'm not finding something because I'm not using the right keywords. I'm used to Web applications and this is really different for me.
