Hello, I am new to android development, and got a few questions, I've read a bit about databases and as I understood SQLite is more for small projects since its not organized, I am trying to create something similar to snapchat (login, register, friends, send messages to friends)
so I'm assuming i should use MySQL for it, I used to do web development so I have experience in it.
After a little researching on the web I've found nothing too much about using MySQL in my project, saw that i have to use JSON to do it, but I'm struggling a little to understand the concept of it, could anyone explain it to me?
and can i develop my application first of all on my localhost and then when its done buy a host?

Hey all, figure this is one of the forums with lots of developers so who better to ask.
I have been fruitlessly trying to learn c++ for a long time now. I have read lots of books and tutorials and watched several videos, where all of these seem to be lacking is making the jump from console programming to apps that actually create a gui and interact with controls.
I understand all the basic concepts and how to use them with respect to programming on the console. Can anyone point me to a tutorial or information on building something useful that starts from scratch and helps you through to the end product, such as a simple mp3 player or a database for collecting items of some sort anyhting that teaches you how to program outside of the console and have user interaction would be helpful thanks.
mini mfc is prob what you are looking for

Hi,
I have an easy question...^^
How can I program programs for my phone?
Is there anywhere a tutorial or something like that?
Or are all of you just very high skilled programmer?
I'm very interested in programming, but I only handl Java and php..
I hope someone of you can explain me where I can learn this =)
Greetings
Chris
PS:I hope I posted this in the right section...^^
PPS: I'm from Germany so I'm sorry for any mistake in my sentences and I hope there is also a German programmer who can show me a tutorial on German, but English is also OK.
I asked this question a few months back and no one helped. Here is what I have been able to find on my own:
To program for your Windows Mobile device you need Microsoft Visual Studio 2005 Standard edition or later. That is an expensive development program. If you buy that program, you can download a Windows Mobile plugin for free that includes an emulator for debugging.
I personally refuse to shell out tons of cash for the ability to program for my phone for personal use. I have not been able to locate anywhere on the internet even the slightest hint of a way that I can write a program for my phone with open source or free software. I use notepad++ and g++ for my coding needs so I was really hoping for a way to program using only these tools with perhaps an additional library.
Speaking of libraries, open gl es is open gl for embedded devices such as your Raphael. I have been unable to find an open gl es tutorial that does not involve buying Visual Studio.
If anyone can find anything else, please post here.
I've used C# and C\C++ to write programs for Pocket PC\Windows Mobile. Java I believe you can use with limited functionality (not the same as on the web). Php is a web langange I believe??
Are you using C++ via Microsoft Visual Studio, or do you know how to compile mobile programs without dropping money in Microsoft's bank?
@Chunkyeggfoo
I know that php is for the web
I only wanted to show, that im not a totally noob in programming ^^
But my question was: Where do you learned this? Did you have an online tutorial, or from school? Or somewhere else...from a book maybe?
Here is one answer to the question.

I have never followed this guide because I use Visual Studio 2008. I started programming using visual basic .net (VERY EASY TO LEARN). Later, I wanted to write applications for the today screen and I needed to learn C++ and the win32 API. (NOT FUN!!!) The good news is that I have several programs that I use on my today screen including weather, calendar, battery monitor, task switcher, music player and an alarm. It has taken me about a year to become pretty proficient. NOTE: when you move from managed code (.net framework) to unmannaged code (C++, win32) you have to be VERY careful to properly manage device memory or you will end up with memory leaks.
I've attached a picture of my today screen to illustrate the possibilities.
Have fun

You can also download evc4 and the evc4.sp4 from the following links.

This will be a very powerful tool but probably very hard to learn too...
Check out this thread. It has lots of info.

You can take a C++ programming class at most community colleges (not state or UC, ie very expensive). im currently taking the pre req that will allow me to take it next semester.
I think,the simpliest way is the Basic4PPC(Basic for PocketPC). Use Google and search for it.
programming
i guess the best way is learn C#, i'm a visual basic programmer and the best app you can do with it is database app, if you want to do more powerful app for your phone is better to learn C#
i'm learning c# right now
try these two

I've been programming for 3-4 years, about 1-2 of those years in C++(the rest in html, php, gml, js, and crapy stuff like dat). No Java, but I've heard its really easy to learn especially if you already know C++.
anyways, I've read the google tutorials and they haven't helped me since they make you download code instead of writing it (like the notepad tutorial).I've also seen all the videos that explain how android works, and I've read the stuff about it. I just want a tutorial that walks you through the process of programming an application.
basically what I want to learn is:
- How to tell if the user pressed a button, or interacted with a view
- draw an image to the screen
- open and close activities, like for a game you switch from the 1st level to the menu
- How to save data to a file, or database(whichever is best)
and things like displaying a list of items, or an alert and stuff like that.
I already setup eclipse and ran the Hello, Android application in the emulator AND my G1 with adb. So I just need to learn how to write the code
My goal(currently) is to make a picture on the screen move to the right when the user presses something(button, key, trackball, screen), but with my code, not cut & paste. I'll just turn that into a game later.
please help me with this, I've always wanted to develop apps for android(ever since I heard of it ). sorry if this sounds like a retarded question, but I've searched everywhere and I haven't found a good tutorial, and I cant buy a book
PS. I use the eclipse plugin for visually designing the layouts

I don't exactly remember from my HTML java applet days, but you can write straight to vm's frame buffer and write a simple program to change the position of the element scrolling it either way you want. Also, java input in html applets can be aided with javascript, so i used javascript to listen for user input and then have java respond to it, but that was over 10 years ago and I dont remember now T_T
really? thats helpful...
EDIT:
I've already read these tutorials on java: http://www.freejavaguide.com/corejava1.htm
I haven't really done anything on the programming side of things since VB6.0. Learned a bit of C once upon a time, but never really got anywhere.
Can any of you fine Devs here point me in the right directions to begin learning how to program for Android? Remember, please, that I will likely have to unlearn some things, and that I have ZERO JAVA experience. I would love to be able to make some apps to fill gaps that I see in the market.
I am running on a dual boot lappy with Win Vista and Linux Mint 10(Ubuntu derivative). Links or pointers to what I need for both sides will be welcomed and appreciated.
im reading hello android v3 and its great so far.. ive also been going thru android source.. download the android sdk and eclipse for linux and or windows.. i prefer linux as does most devs. ive also registered for night time java classes at the local community college for 13 bucks a semester. anyways goodluck!
This might be helpful for basic syntax stuff.
Start with fattire's link and pick up the Java basics. To read Android examples, you'll need to understand how Classes and Interfaces work as well as how to extend and implement them, respectively. You'll also want to understand inner classes and anonymous inner classes. Understand variable scoping in classes.
Learn how threads work. Understand the implications of multithreading and reentrance. Experiment a lot in simple, stand-alone samples.
Once you've gotten started with Java, you can download Eclipse and the Android SDK. Here's the Android "Hello World" tutorial, which is a reasonable place to start. It has pointers to everything you'll need.
http://developer.android.com/guide/tutorials/hello-world.html
Android Applications are pretty straightforward once you understand the basics... AppWidgets and Services are less so. The trick is to understand the lifecycle of each -- where and when it's appropriate to do what sorts of work and how to communicate results between different components. It will be rough going in the beginning with a fair amount of crashing as you discover you're taking too long to do something that really should be offloaded to a different part of the lifecycle or a whole new thread -- or when you discover you can't do something you want, directly, because you lack the parts and have to send a message to something that does have all the parts.
My first project was a simple button on the home screen that, in effect, runs a few commands. It took me more than a week to make it work properly, and I was already familiar with Java.
Also understand that some of the examples floating around -- even those from Google employees -- are old and that Android has had some growing pains. Double check the approach suggested by anything that's older than a year. The SDK contains sample programs that make for decent cookbook code.
thanks to all of you...as well as the mod who moved the thread to the correct spot...wasn't sure if this was the correct one.
Hello android (as mentioned above) is awesome! Another good one is Beginning Android 2. Both found here:]

Hi XDA!
I know the forum is mostly aimed at mobile dev but the people here are so good i thought it the best place to ask a question regarding dev in general.
I have a database (mySQL) with rows that contain latitude/longitude values representing the locations of customer complaints. I'd like to plot these on Google Maps / Earth and put up a dashboard so that we can see if there's any particular location that's a 'pain point'... any idea how to do this? I need the plotting step to be completely automated cos I already know how to automatically insert new rows into the mySQL table whenever a new complaint comes in.
I've done some Googling and i usually see people talking about manually importing an Excel file with the co-ordinates... This won't work for me cos we get thousands of calls coming in daily and the whole process needs to be completely automated for it to be practically feasible.
Ok, some background about me: I'm not a 'proper' developer... I've never worked in a structured dev environment. I'm just someone who knows a little bit about dev and I've had to write some code cos there was nobody else to do it
I can do some mid-level Java (I've written a few servlets that run on tomcat ...they listen for HTTP requests and respond with some XML... nothing hectic) and I know enough about mySQL to be able to work with it comfortably.
I'd really appreciate any help with my plotting question
