Hello there,
I just started using Eclipse and I'm confused by the appcombat_v7 and fragment_main.xml.
I've never seen those files in a youtube-video I watched for tutorials.
Do I need them?

Depends on what you want to do and what version of Android you are supporting. Using Fragments is usually a good style, but you need to make sure you understand them, so head over to the training class on fragments. To clarify with the appcompat-v7, that is one of the two support libraries which were released not so long ago to port some of the features and layouts only found in higher android versions back to v7 (which is 2.1) in this case. The v7 support lib is used to get the ActionBar in earlier versions. If you want to use fragments and support pre-Honeycomb, you'll need to use the v4 support library, which is just a jar file.

hey everyone,
i've tried several roms and i like the idea of creating one.
i know how long of a process it can be and how many lines of code,
but i still want to do it.
i was wondering if there is someone else's rom i could use as a base?
if not how do i go about starting from scratch?
any information would be appreciated.

I believe some devs such as cvpcs may have released his source, but im sure most keep it private. To build your own, grab the android sdk from google, their source code, and the source for the 2.2 release for droid X

alright i'll look at some developers and then i'll check out the sdk, thanks!
so i downloaded the sdk and everything, but i don't know how to get to editing and working on the stock 2.2.1 2.3.340 rom!
right now i'm just doing some easy stuff like making the boot animation
and designing some stuff on paper.

You'll need some java knowledge, as I believe android is built off java... If you have some java programming experience, you're a step ahead. I believe Google also has some documentation and tutorials on their sdk page or a link from there.

yeah i'm currently in the second half of a java programming class that is offered at my university.
Has anyone successfully upgraded their nst to android 2.2 or higher?
If it isn't possible, how difficult would it be to modify the api of an apk to become compatible with android 2.1?
it need alot of work to modify the controls.of android 2.2 also the kernl if need ..... why u need upgrade android version ....... u must know tha nsr build for read only , and android 2.1+root fair for me indeed
Sent from my NOOK using xda app-developers app
In order to utilize the full features of an app I am trying to use, I need to run Android 2.2 minimum on my nst.

mantano, perfect viewer, aldiko etc. they have been upgraded to function only with 2.2+ , i know, there are old versions still compatibles but newer have functions that may be desiderable

you need to disassemble the apk with apktool then modify the android:minSdkVersion value in AndroidManifest.xml to work with an early android version but it is not guaranteed that works
i have never do that but there are many tutorials arounds
Hi everyone, I'm new to the android programming playground and it looks complicated. I have no experience in Java, only in Python and JavaScript. I have seen some tutorials before and I just don't understand the .java file. How do they connect? public void? What is this? I don't want to use ruboto or kivy or phonegap or anything else because I want my app to be independent. I have no problems with the xml files because I have worked with HTML files before. The only thing is the java files. Can someone give me a nice concept of the android programming language? About how do the files get wired, about starting an activity, and more if available. The android programming tutorial on developers.android.com never helps. Any help is appreciated!

If you have worked only with python and JavaScript, Java will certainly feel like an alien language. In addition, navigating through eclipse can be a pain as well. Learning three things (Java, usage of Eclipse, & Android Development) together is next to impossible.
I would suggest that you pick up on the basics of Java first. That will make your development with Android easier.
You should also go through this thread: Free Online Mobile Development Courses (Java, Android, etc.)
Thanks a lot.
Nice reply. I finally found the information i need. You are right. I need some java basics before starting. Actually what is the relationship between android and java?

Android is an operating system. To develop Apps which work on it, you use Java, and call the various methods provided in the Android API.
Your App is compiled to bytecode. They are then converted from Java Virtual Machine-compatible .class files to Dalvik-compatible .dex (Dalvik Executable) files before installation on a device.
Dalvik is the process virtual machine (VM) in Google's Android operating system. It is the software that runs the apps on Android devices.
You can also use C++ to write for certain low level processing, which is faster than running in the Dalvik Virtual Machine.
To simpilfy you can think of android as a framework written on java like BootstrapTwitter written on JavaScript

So... you meen like Ubuntu is an operating system. To develop apps for it, I use python. Am I right?

hi! I need to build and modify the stock phone app.
I'm using Android Studio, I clone the git source (github.com/android/platform_packages_apps_phone) but when i try to build without modify anything I have this error:
/home/user/Phone/phone/src/com/android/phone/INetworkQueryServiceCallback.aidl:19: couldn't find import for class com.android.internal.telephony.OperatorInfo
I think that this class is in another packages (github.com/android/platform_frameworks_base).
How can i do?
thanks! :good:

Yeah, there are dependencies on other ROM specific packages. I don't think that you can build this without building the whole ROM.
As far as I know, all phone apps have to use an API.
ok thank you. I will build entire ROM. I think this could be the best solution.
Hello everyone, I'm having another really annoying problem, and it's :
I Can't build assets with "somc_color" lines, like somc_color_accent_light or anything related to Xperia theming engine.
Why i don't use Apktool?
When i compile the assets with 5.0 framework, those assets will return "white" in 5.1 System, So the only solution to build it using Eclipse, And i've tried Android Studio, the same, i need to define it in the SDK, but that's hard and a waste of time maybe.
So, anyone got an idea?
I've tried up to 12 frameworks, all with the same result .
Thats I question I asked before. But I'm not sure. Very interested to know as well

DeviceDefault, add this in your style to make it according to Xperia Themes, BUT the annoying thing is if you're using latest AppCompat, then you need to parent it, and it will be impossible to make the app according to Theme Colors .
