You need to learn coding. If I recall, Java.

Usually, eclipse is used in developing android apps but other IDE can be used as well(with the installation of the appropriate plugins).
You can follow the following link to setup everything and make a simple app: http://developer.android.com/training/basics/firstapp/index.html
The app can be tested on an emulator or on a real device

SDK
As per the site given, you will have to install the Android SDK, and get at least one firmware for an app to work. then the guide will go through creating and testing your first app using cmd or eclipse(classic version 4.0 should work), with android development tools installed. happy creating!

Basically you need to use ADB in the android SDK; or Get Root and chance the prefs. DB.
Android central has a app, you dont need to root your device.

[Q] Flashing ROM over an emulator?

Hi
I have made some modifications to an MTD ROM posted in dev section.
I would like to test it on an emulator before I flash it to my actual device.
I installed Eclipse (with ADT plugin) and downloaded some Google APIs (2.1,2.2,2.3.3) but I haven't seen our device in the list...
So I just launched a virtual device based on 2.3.3 but I don't think it is heping me much, it's just a general 2.3.3 android device.
My questions are : (and I did read quite a lot, maybe haven't looked in the right places)
1. what target do I need to download and add to AVD to emulate SGH-T959V ?
2. How do I get it to function with recovery ? and actually flash kernel etc.
3. Do I need specific actions to emulate MTD over our phone ? same as in real phone ?
4. Will I be able to virtually flash a ROM on an emulator ?
links to constructive/informative sources are also appreciated.
Thanks a lot !

I'll rephrase, how do you guys test your ROMs prior to flashing them, or you don't...

I have been trying to do that for a while. What I've discovered is that you can build emulater version from source, or use a nandroid backup.
Sent from my SGH-T959V using xda premium
I was messing around with this last night, but couldn't get a nandroid backup image to load properly in the android emulator. I was following these threads:
http://forum.xda-developers.com/showthread.php?t=1591924
http://forum.xda-developers.com/showthread.php?t=906161
I'll get back to you if I find anything else that works.
I couldn't get it tot work either, but I thought it was just me.

ummm...The giant link that says download?
Make sure you have the Java SDK installed for that tool! It's a .jar file.

If you're trying to run the original .jar it will have to be run under linux/OSX...though there is a windows port as well.

The .jar works perfectly fine on Windows assuming you have java installed. Windows typically requires more effort to get everything set up and Adam didn't feel like dealing with those issues by outright saying it supported Windows.

Please help me?

I made a not to wise choice and bought from a china store. The mini tablet I bought has no app market installed. I have download many "google play store '.apk'" files and they all install, when I open them, they crash RIGHT off the bat! I have done this at least 5-10 times.
If anyone...anyone... can help me, please let me know! Please, please, please.
Thanks a ton for anything,

Ok then, make sure its the correct play store for your Android version (GB gapps won't work on ics and vice versa).
And if you have a custom recovery, try flashing Google apps

Rooting methods are different for each device, but you should probably try using superoneclick or unlock root.
(You need drivers installed)

You can check this method but you nead to know if it is the right one for your android virsion first...

GOogle them, superoneclick is a .zip file you must unzip it and open the application, unlock root is an .exe just execute it. They both are one click root programs. Very simple.
And China phone companies don't have many root prevention security (they don't care) so either one of those should work

Nope, both PC applications. You have to connect your phone and run them.
They are two different applications, so if one doesn't work the other probably will. If neither work let me know

In order for the computer to recognize the device, it needs drivers. They used to come on a disk (way old school) but now they are usually online. Chinese tablets drivers are harder to find, but there has to be one out there. Try googling "<model> drivers"

That's the stock system recovery. Just used for wiping the phone and applying updates (if they ever release any lol). After rooting, its usually changed to a custom recovery for phones that have enough development, which allows way more options. But that's another matter.
If you REALLY cannot find the drivers (I couldn't either, could barely even find the model.) then your only chances are to root with gingerbreak or z4root, but both were meant for Android 2.3 and below. They're applications, so couldn't hurt to try them, but by now there is a very low chance.
SoC and UR both work amazingly well, maybe you could try contacting not the sellers for the drivers but the manufacturer (chinavision?)

What are 'SoC' and 'UR' ? If I root it with one of those, will it become Android 2.3?

Oh sorry for not clarifying, they're just my abbreviations of super one click and unlock root.
Rooting won't change your operating system, its just that methods meant for older versions of Android, like gingerbreak, probably won't work.

i have 2.2.2 on my phoenix
Go on the market or your browser and search for an application called 'z4root'. If you're running 2.2.2, it should work like a charm. If it doesn't, also try GingerBreak. These are both great one-click applicatoins that are almost fool-proof rooting tools. GingerBreak (not sure about z4root) also includes a feature to unroot your device as well. Best of luck.
