There's an open source battery indicator that I greatly prefer to the default one. I was wanting to modify it to replace the default battery indicator. Is this even possible without building a whole custom ROM?
Yes, it is possible to do without building a new custom ROM, but you still need root access. the .png files for the battery indicator are in the framework-res.apk, you can extract that, replace just the .png files for the battery and put it back with approriate access rights and it will work. kinda like the process to just can change the "Verizon Wireless" (or other carrier) text on the lock screen.
I do not believe it is possible without building a whole custom ROM.

I should study some apps of different kinds for homework, also want to determine what kind of font are in use.
I try to open the different apk but don't know where to find the setting about the font (or font-family).
Can't use online imagine font detector, because are imprecise.
You could reverse engineer it, which sounds harder than it is for this purpose.
Get a tool like Apktool (https://ibotpeaches.github.io/Apktool/) and decompile the APK.
If all goes well, you find a folder called res/font, which should have the folders for each font used inside of it.
From the app itself it is not possible to find the font used (unless it is a text processing app where you can select the font yourself..)
How to change Android emulator booting animation
The emulator uses an Android OS image to boot. You can't change this without changing the image. This isn't emulator specific, but for Android in general.
For more information on how to do that, you might look here, or just google "android change boot animation".
Once you have a new system image, run emulator -help-disk-images from your sdk/tools folder to see a ton of useful info about using disk images with your emulator. It tells you where to put the file, which differs depending on whether you're using the standard SDK or not.
That is not a string, it is a bootanimation. You can't set it to another text. You can change it so it is another animation though.
If you want to see other possible boot animations, google android boot animations.
For some reason, this is what most of my students and trainee ask about in every customization class.
The answer for that is - Of course you can modify that image .
To make a long story short:
You can actually do it for every device by storing a noncompressed zip file at /data/local/bootanimation.zip (just copy from CyanoGenMod and make sense of the animation layout and timing - that's the easiest way, and it explains much better than any explaination).
As I wrote in some other StackOverflow post, there are a couple of places you can do that (I disregard the encrypted case for the sake of simplicity):
system/media and /data/local/ .
The latter is preferable as it makes it easier to modify, and does not require the tedious
modification of the system.img (system partition) size.
Note that bootanimation.zip should be lowercase, and -0 compressed.
That is argueably the easiest Android customization (Well, if you have good graphic designers...)
That's not part of your application, is emulating an device. Remember that each android device have it's own Start up images and icons that can be related to the carrier or the brand of the phone, etc.
You cannot change that image, anyhow for what propose you want to change that?
Place a animation file in location /system/media/bootanimation.zip to override boot animation.
If you google around, you will find lot of tools to help you create boot animation (even from videos).
i want to make to make an PreferenceActivity with the same style that can be found on the image below.

There any way to make a close match of it or do i need to program the behaviour?
I can think of two ways you can do. One is to download the source code, but I think that layout is custom for galaxy tablets.
The other option would be to use the Hierarchy View Perspective in Eclipse to determine the structure and details of the interface and from there replicate the interface.
Good luck!
Udapte:
Ok, if what you want is the drawables you can actually get them from the tablet. With a file manager in the tablet copy the file /System/app/System.apk to the SD card and from there to your computer. There change the extension to .zip and extract the contents. This way you can access only the drawables. The xml files are compiled so you can't see their content.
I think you can use this if you want more data out (like the xml layouts): http://code.google.com/p/android-apktool/
Although as I said in the comments I am not sure about the legality of this given this is Samsung's own IP.
If you create an activity and set a label without disabling the title bar you will see a title that uses a gradient as a background. Is there a way for me to re-use this resource without re-implementing it?
Thanks
I believe the background for this comes from the resource that is called "activity_title_bar.9.png" that is in the system drawable folder.
Here is a copy of it:
If you download it from here you'll have to rename it using the .9.png suffix. You can also find it in your SDK. The path is "SDK\platforms\android-4\data\res\drawable"
Note android-4 could be any other number that you happen to have installed on your machine.
Generally if you are wanting to use a system resource like this best practice is to save your own copy of it and include it in your project. Resources like this are subject to change at any time with new versions of the OS (or even with device specific skins that Manufacturers add on to the OS) So if you rely on the system copy from inside your app then you have no way to know for sure that it will look the same across all devices.
I'm a new in Android and Java and I have the following problem. I want to change standard resources, such as button background, programatically to allow applications using standard buttons be displayed with custom background. My problem is - how shall I identify the path for retrieval resources on phone or emulator? And if we have permissions to access to those resources?
The only way you can change "standard resources" for the entire device is to modify and install your own firmware.
