Android comes with many built-in drawables that are listed on this page. Is there any page where one can see what each of these drawables looks like?
E.g., we need to display a green check and red cross depending upon whether a web request succeeded or not. We would like to see if there is any built-in drawable we could use for this instead of creating our own drawables. But the web page linked does not show how the drawables look like so we don't know if there is a built-in drawable that works for us.
Is no such web page exists, does anyone know how one can iterate over the built-in collection of drawables? Then, we could try writing a program ourselves to do the visualization.
I'm not sure that I understand your question correctly, but if you are using Android Studio, try right clicking the resource folder -> New -> Image Asset and then choosing one of the icons. It gives you a preview of what the icons look like.
Here is an app to visualize the built in icons in a photo gallery. It lets you quickly browse the built in icons and search what you are looking for.

I've just finished creating a bunch of icons in Adobe Illustrator for my Android phone. My problem is now, how can I make an icon pack like those you can download from the Play Store? You might think that there must a lot tutorials for this purpose, but I don't seem to find them useful, and it confuses me more than it benefits.
Any help will be appreciated.
Thanks in advance.
Try this instrument (Icon generators allow you to quickly and easily generate icons from existing source images, clipart, or text.): https://romannurik.github.io/AndroidAssetStudio/
Firstly, whichever icon you go with you will need different resolutions of it such as ldpi, mdpi, hdpi, etc.. and that can be done in two ways,
Manually by making each image the correct size
Using a asset generator like Android Asset Studio https://romannurik.github.io/AndroidAssetStudio/index.html
In terms of creating the actual icon, you dont need any specific "Android Icon Tutorial". You can use any generic logo or icon tutorial and just create it in the correct size. Read this link for icon sizes:
https://developer.android.com/guide/practices/ui_guidelines/icon_design_launcher.html
Then you can simply watch and "logo" or "icon" tutorial and follow along. Then I would use Android Asset Studio to create all DPI's
And this one for other icons:

I've been trying to create an image button to use in my test app. Once I've imported the asset it looks grainy and pixelated, especially compared to the app_compat radio button. Here is the comparison (custom asset on left).
How can I get the edges of my custom asset to be as clean as the radio button?
You need to provide assets for various screen densities. If your app is not providing such assets directly, then Android will try to make such by usually scalling what your app provides. This usually ends with pixelated graphics. Please read this article about how all this work in Android: https://developer.android.com/guide/practices/screens_support.html
Previously I made some apps with Adobe Flash Builder. That's works great but is not the best choice is some cases so I start with developing Android apps with use of ADT.
Like in Flash Builder you can set several icons for different screen resolutions. I can understand why but found it is not really necessary when creating one high resolution icon, this works fine (scaling down is better than scaling up). This also avoid the extra work that is needed to create these icons, just one icon.
Long story short, I want to create just one icon, 144x144 pixels at 96dpi and tell Android to use this icon.
Also I want to point the application icon to the asset directory instead of the res/drawable directory. The reason for this is that the icon can be reused by the (web-)application and for another reason, I have made a webApp tool to create a compressed version of a webApp and put the contents in the asset directory of a Android project.
Because the webApp can also run in the browser I have already created some icons (like favicon, apple-touch-icon and apple-touch-startup-image) and want to reuse these icons in the Android project automaticly.
The idea is also to create an application project template so it is quite easy to create a android app of a webApp.
Question
Andy idea how to change the location of for example the application icon? Using a path doesn't work (it generates an error, can't compile).
android:icon="#drawable/ic_launcher"
android:icon="assets/appicon.png" #<- doesn't work
Actually found the solution myself and is pretty simple. The only thing that is a bit tricky in ADT to validate the new declaration because at first 'it says' that the declaration is invalid. The workaround is to cut (ctrl+X) the declaration, do a project clean by Project|Clean and then put it back by paste it again (ctrl+V). Weird but true ;-)
You can declare a string resource like this (in XML file):
<resources>
<string name="app_icon">assets/appicon.png</string>
</resources>
android:icon="#string/app_icon" <- this works
Then you can use just one high-res icon image as icon for all devices! Looks great! See also picture below (between red rectangle ;-)):
I want to add a feature on my app to let users give a feedback on data. (for example to report errors or mistakes).
Is there a standard icon for it?
please, visit your android-sdk-* folder, there should be default set of icons and pictures in the ./platforms/android-XX/data/res/drawable-Xdpi/ where "XX" and "X" stand for your android version and screen size. all the standard icons are there.
There are a few system icons whose filenames match 'feedback', but none of them look appropriate to me.
Best I could find is "ic_menu_report_image.png".
I've been using "ic_menu_start_conversation.png".
Whether it’s useful for your app mainly depends on the iconset you’re already using. In a chat-app for example, this icon would be a poor choice :)
Note: this icon is marked as protected. You'll have to copy the images to your source manually.
Because these resources can change between platform versions, you should not reference these icons using the Android platform resource IDs (i.e. menu icons under android.R.drawable). If you want to use any icons or other internal drawable resources, you should store a local copy of those icons or drawables in your application resources, then reference the local copy from your application code. In that way, you can maintain control over the appearance of your icons, even if the system's copy changes.
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.
