I've been experiencing an issue with creating an icon that fits in any size and shape. I use Studio to do it, but I must be doing something wrong, because there is a small padding in it.
I add my image asset as background layer with nothing in foreground layer.
I've tried to fix it by trimming it and using huge icon source 1920*1280.
When I changed to new theme it turned out that few other apps on my phone(other devs) have same poor icons.
Also tried this
Creating an icon using foreground layer totally solves this issue.

Has anyone worked closely with the Material Shape Drawable and similar stuff?
The task is to make such a cutout without fail using a gradient and always with a fixed size. The implementation of the picture is not suitable.
And the cutout changes its size depending on whether the panel is closed or not
There are at least some ideas - I'm not sitting for the first day
Hello friend this is called "cradle" of bottomAppBar FloatingActionButton.please refer here to learn more https://medium.com/#vadim.zhukov/easy-way-to-make-curved-bottomnavigationview-with-floatingactionbutton-12b979009e64
I am trying hard to get rid of the extra margin around the ic launcher icons generated by Android Studio without luck. I know this is one of Google's material design trends. Though, the icons are so small on devices which is ugly.
I have Googled for around three hours and the only workaround I could find is to generate the clipart with a transparent background and photoshop the background with rounded corners which is pretty slow.
Is there a better solution than this?
Thank you.
Per the Designing adaptive icons blog post, the adaptive icon images created in the drawable directory for use on API 26+ devices follow the adaptive icon size and shape:
You'll note that while the entire image must be 108dp by 108dp, the actual visual area is only the center 72dp - the outer edge is only seen when dragging the icons around (where parallax effects may cause it be visible).
The Pixel Launcher, as well as many third party launchers, enforce the use of adaptive icons on API 26+ devices, so you should always design with that requirement in mind - the alternative, in the Pixel Launcher's case for instance, is to place your non-adaptive icon within a white circle.
Therefore you should always design your icon such that the background layer takes up the full size, but any foreground image you put on top of that background layer should be contained within that center area.
You can't just remove that margin without the foreground image being messed up, but as per the Implementing Adaptive Icons follow up blog post, you can remove any white excess around the foreground by putting your trimmed image within a transparent drawable of 108dp x 108dp by using an InsetDrawable.
<!-- Center a 54x54dp image in the 108x108dp size of adaptive icons -->
<inset
android:drawable="#mipmap/ic_fg_trimmed"
android:insetLeft="25%"
android:insetTop="25%"
android:insetRight="25%"
android:insetBottom="25%" />
Although this would have to be something you'd need to do to the ic_launcher_foreground image yourself after the fact.
A better solution, in most cases, is to use vector drawable images as the input to the Android Studio Image Asset wizard - this will ensure they are always the right size and don't take up any additional space in your APK.
I think i had the same problem as you. I solved this with a nasty hack, in the AndroidManifest.xml I just changed the roundIcon to point to the standard icon.
<application
…
android:icon="#mipmap/ic_launcher"
android:roundIcon="#mipmap/ic_launcher"

I created a transparent image using gimp, and used it as Android apk icon. But when I installed the apk on my Galaxy S3, there is a shadow when display the icon on my screen. Since I can't post image as a new user, I posted the image at:
http://www.guangnaqu.com/P1030055.JPG
Please noticed that other apks' icons are ok. Also the icon displayed ok on Android emulator.
Please let me know how to fix this.
Thanks.
It might be TouchWiz causing the problem.
I had a similar issue in a previous form of TouchWiz where it would make an entirely new color background of its choosing.
1.Edit it with GIMP http://www.gimp.org/ for an invisible background. just throwing out options JIC it is the image editor
2.Try to give the background something like a 0.05% Shader background setting that cannot be distinguished by the phone screen, but is seen by the UI.
Is anyone else having this problem? http://android-ui-utils.googlecode.com/hg/asset-studio/dist/index.html When i try to use an image and i upload the image it just turns out to be a grey box. I have tried in all different browsers and still no luck.
You probably have one of two issues.
1) To verify if the image is getting processed, make sure you select 'Launcher Icons' from the main screen as a test. Other icons are not full color, they are Grey or black or white. For Example, the icons for the Action Bar are supposed to be Grey (depending on theme). See the action bar design guidelines. If you see your icon, but it is square instead of it's native 'shape' you have the second issue.
2) Use gif (or png) as your original and make sure you set the transparent color when you created it.
The tool works well for me in several browsers. I suggest you try a different browser, and make sure your bitmap isn't corrupt.
I have realized that there are at least two background colors on Option menu of Android. On the HTC Hero, the background is white and on Samsung Galaxy S II, the background is black.
This became a problem when I set the icons for the background menus. Is there some way to detect the background color of the Option menus in Android?
Possible solutions:
Don't use icons.
Design icons according to the guidelines - http://developer.android.com/guide/practices/ui_guidelines/icon_design_menu.html. There are three different guidelines for up to 2.2 (white background), 2.3 (black background) and 3.0+, so it's a lot of work...
As Profete162 suggested, use #android:drawable/ic_menu_*
For Android 4.0+, you can also set the light / dark Holo theme, which is guaranteed (at least in theory) to remain unchanged across different phone manufacturers - so it'll look the same in HTC Sense, Samsung TouchWiz etc.
That's indeed a very annoying issue.
On my implementation, I always try to use standards icons from android.R.drawable.IC_menu_*, so I am sure these icons are part of the framework and users are always positively surprised to see their generic icons in my app!
That gives a really good continuity in the user experience on the device, but that doesn't answer your question, but at least provide a workaround.
Here are for instance all android 2.2 icons: http://androiddrawableexplorer.appspot.com/
You can trust me, using these icons will always fit your colors.
First of all to answer your title question:
You can reference and read the background of the options menu by reading the attributes of the current theme. The attribute for this is panelFullBackground. E.g. set it as the background of a textview in XML¹:
<TextView android:background="?android:attr/panelFullBackground"
... />
Note that the background seems to be a solid color, but it's not - it's actually a bitmap. If you look closely you can see a grey border at the top (android 2.3+), or a drop shadow (<= android 2.2), so its'a bit difficult. Luckily there is a different attribute called panelColorBackground which matches the background color of the drawable as close as possible. So if you want just the normal background color, use this instead.
¹ This can surely also be read from code, but I don't know how from the top of my head at the moment, maybe I'll look it up and edit it in later.
Regarding icons
So you have the color as stated above, but you still have to process it to know if it's a dark or a bright color. You can do that, but that's not the usual way to deal with these icons and probably a good bit of work until you cover all the possible cases - not to mention that you have to create icons for each variant.
Normally you should adopt the platform menu icon style. This works across all devices and looks familiar to your users (custom icons that dont follow this often look "wrong" - e.g. astro file manager does this I believe).
You can do that by hand (see the guidelines), but the way better alternative is the Android Asset Studio.
It comes in two flavors:
As a webapp
Integrated in the latest version of the ADT plugin for eclipse
(under File->New->Other->Android Icon Set)
The workflow for both is pretty similar, select the point "Menu Icon" and follow the wizard. It will promt you to enter a simple, black and white bitmap of your desired icon that just outlines it's shape. After you specified one, the asset studio will generate everything for you. Play a bit around with the "clipart" option, that has a few example bitmaps ready to see how it works. When finished, the webapp gives you a simple zip which can be extracted into your project directory, the eclipse version adds it directly to the project that you select in the wizard.
The background color can be anything, because its implemented in Framework by manufacturer. You can't read it, in fact you will never need to read it.
Just create your custom menu layout in res/menu folder, set style and use it.
