I see that most development chat here is for system software, kernel, etc.
I would like to begin writing apps for the Android OS. I have a GN2.
I've installed Eclipse and have installed the last few SDK versions.
I eventually want to build an app that will allow a user to log into a web site and retrieve data from a database file on the web server using other phones also.
I'm an old Visual Basic programmer and have a little C# familiarity. Don't know much Java at all.
What else might I need to download and install into Eclipse to be able to write an app to access a database file on a server?
Anyone know of any app templates that can I can download and start off from to learn the process of writing such an app?
The database will be mySQL probably. Could be an Access or Sql Server file.
Thanks in advance,
Barry

Hello all,
I'm a developer (with less experience) for a company which is developing an app which will be side loaded on devices which are to be distributed. I've read about, and tested some methods with linking Android Market apps to sideloaded apps, provided they have the same signature and .apk file name, but our company does not want market exposure for this app.
My idea is as follows:
1. App checks an ftp server running in some location for a file with version info to see if the current version matches the version on the device.
2. App downloads .apk and relevant data to device
3. App then triggers some sort of "update" which will install the new .apk and replace the necessary data.
Alternatively, what is typically done in this instance when someone wants to update a non-market app? The Amazon App store is an example of a non-market app which updates itself, so I know it's been done before.
How does one go about writing a class which will update the app that it's currently running in? Are there any tutorials or code walk-throughs for this?
Any help from fellow developers is appreciated.
Look at this links:

Thank you for the links - I've been toying with code since then.
But wow, it seems there is very little information out there about this . . .
If you don't want to maintain you own update server, you may try this: auto-update-apk.com
Android client is open-source under Apache 2.0 license, so you may see how it works and make any changes, if necessary, before incorporating into your own project or using it as a starting point of your project.
I want to develop a file encryption app, but I do not know how to begin and how to do. Hope some stagers could give me some thought and guidance. I am the new one for android.
You may want to look at the Java Cipher and Java CipherInputStream classes. Since I am a new member I cannot link you to the Java documentation on these, but doing a simple Google search should yield them as the first results.
With these you should be able to accomplish a file encryption application. Depending on your knowledge of encryption algorithms you may want to start by learning about DES as it is a little easier to implement with the Cipher classes.
Hi all!!!
I am new on development of android applications and I need some help. I need to create an application that have to show some flash content and have to connect to external server, I think with an WebService.
Do you have any recomendation or any limitation on this plataform?? I need to upload the flash content idealy with the same webservice, like a sincronization process.
I think that the WebService application is going to be on PHP or Java Server Page.
best regards!!!
Well, if the entire app will be flash, you can make the flash file in Adobe Flash, then export it as an Adobe AIR app. Adobe AIR is a platform that turns Flash files into apps for iPhone, Android, etc. I don't know the specifics, but that's what I have read.
Hope this helps at all,

So im trying to launch phone applications e.g. com.phone via a html file
is there a method to do this? im not trying to build it into the apk, the apk builds the launcher via a html file.
so basically im trying to do
launch.android.app<app.name.apk>
any help?
Hi i've been browsing the forum trying to find a solution but however i'm limited by my knowledge.
Basicly there is an Game/app made built by GameMaker but the target system was not meant to support AndroidTV. I'm trying to run this game on my nvidia shield.
I sideloaded the app and whenever i launch it i see the background of the game as if it was going to work and then the app crash and i get the following error message :
Incorrect android target. This executable targets android TV devices. This build is for android".
I've download Apk Studio / Apk tool and i tried to find out in the code where would that check happen and how i can allow AndroidTv devices to run this app. However i don't see much in the manifest file that would stop the app from running in AndroidTv.
Anyone out there with more knowledge can chime in and give some ideas ?
Here is a link to the app i'm trying to modify.
