Welcome to the Lawnicons contributing guide! This file will tell you what you need to know to contribute to Lawnicons.
Before you start, please fork the project and clone it to your machine. Afterwards, you can either contribute icons or code.
To contribute icons, you need an icon editor (e.g., Figma, Inkscape, etc), a file explorer, a text editor, and a terminal window.
For additional information on designing icons and samples, see the Lawnicons Figma repository made by Grabstertv.

The canvas is 192×192px
. The content area for most icons is 160×160px
, meaning the long side of an icon should be 160px
. Square icons should be 154×154px
. No fill, the stroke width is 12px
. All shapes should be black #000
with rounded ends and joins. Round 90° angles by 6-32px
. Avoid blackness, close distances between shapes, and drastic changes in stroke widths. Simplify details, but don't lose recognizability. Provide original and localized names, so the icons can be found.
To avoid rework, save time and understand the limitations of the guidelines, it is worth reading reviews of the latest merged pull requests (e.g., +8 icons, +1 link, +4 updates) and creating no more than 5 icons in the first attempt.
The canvas size should be 192×192px
so that there is a safe zone around the icons to control consistency.
All but square icons must fit the 160×160px
content area size. Be careful with abstract icons: the long side should be 160px
, but the other side can be smaller. Remember to adjust the size of all icons when you change the base stroke thickness (12px
).
Square icons must fit the 154×154px
content area size. Icons that mostly fit in a square are considered square. If the icon is kinda square and kinda not, choose a size based on density: 154×154px
for dense icons, 160×160px
for the rest. Examples: GitHub or Figma.
The stroke should be kept at 12px
in most cases. If an icon is too minimal or dense, you'll need other widths: 14px
for the most minimal, and 8px
for the densest. For fine details, you can use 6px
. For more clarification, please refer to the visual balance section down below.
All shapes must have non-transparent black color #000000
, rounded caps and joins.
Use 6—32px
for 90° angles. It is allowed to leave 0px
radius in cases when the others spoil the shape: for example, when a right angle is formed of short lines.
When designing icons, it's important to strike a balance with the level of detail. While some icons can be highly detailed, it's acceptable to remove certain details as long as the icon remains recognizable and stays true to its original concept. In some cases, you may need to completely rethink the icon to achieve a minimalist design.
A great example of this is the Subway Surfers icon as seen in the example above. In Lawnicons, it was reimagined by using the graffiti-styled "S" from the game's logo instead of depicting the character, which would have required intricate shapes and varying stroke thicknesses.
In contrary, it's also important to avoid too few details, as they may not be easily recognizable. Take the Headspace icon, for instance, which consists only of a circle. This may pose a problem for users since Lawnicons are not colored, and a simple circle on its own is not easily identifiable. Whenever possible, incorporate additional details that align with the app's design language.
In the Headspace example above, the circles usually have a face representing mood. By adding one of those faces to the circle, you can make the icon more recognizable.
All icons must adhere to an outline (not filled) to maintain a consistent theme. However, fill can be used sparingly for small details that require minimal contrast or for elements that cannot be accurately recreated with an outline.
The key is to ensure that any filled elements do not overwhelm the overall icon design and align with the outlined style to create a harmonious and coherent icon set.
Sharp contrast occurs when there is a drastic change in stroke thickness without a smooth transition. For instance, using a 12px
stroke and suddenly decreasing it to 8px
creates an unbalanced visual effect in the final icon.
To avoid sharp contrast, you can follow either of these two methods:
- Uniform Stroke: Instead of jumping between stroke thicknesses, use the next immediate increment in width. For example, transition from 12px to 10px.
- Gradual Transition: Rather than making a large jump, introduce an intermediate thickness. By going from
12px
to10px
and then to8px
you create a gradual transition or gradation. This approach helps maintain visual balance in your icon design.
To make it easier to find icons, you should keep the original names and supplement them with an English variant or transliteration. If you are adding a link to an existing icon, keep (or complement) the existing app and drawable names.
Should be the same as in Google Play, F-Droid or the official name. If the name in the source is too long, it's acceptable to remove the second part of the name without loss of recognition.
Wrong • Google Play name: "Zoom - One Platform to Connect"
<item component="..." drawable="zoom" name="Zoom - One Platform to Connect" />
Correct • Edited name: "Zoom"
<item component="..." drawable="zoom" name="Zoom" />
Names are separated via ~~
. If the app name is localized, then the first name should be the one most commonly spoken by the people who will be searching for the icon (if in doubt, in English).
Wrong
<item component="..." drawable="hulu" name="フールー ~~ Hulu" />
Correct
<item component="..." drawable="hulu" name="Hulu ~~ フールー" />
If there are letters in the first 3
characters of the app name that aren't in English, then it's worth adding the name transliterated into English.
Wrong
<item component="..." drawable="lansforsakringar" name="Länsförsäkringar" />
Correct
<item component="..." drawable="lansforsakringar" name="Länsförsäkringar ~~ Lansforsakringar" />
Should be in English or transliterated from the original language. Should repeat the name of the app if possible.
Wrong
<item component="..." drawable="meinvodafone" name="My Vodafone ~~ MeinVodafone" />
Correct
<item component="..." drawable="my_vodafone" name="My Vodafone ~~ MeinVodafone" />
Here's how to add an icon to Lawnicons:
- Your icon in the SVG format, adhering to the above guidelines. The filename must use snake case (e.g.
files_by_google.svg
). - The package and activity name of the app.
Please check the icon tool guide for more information.
-
Add the ready SVG to the
svgs
directory. -
Add a new line to
app/assets/appfilter.xml
(in alphabetical order, by thename
attribute), and map the new icon to a package name and app's activity. For example:<item component="ComponentInfo{com.google.android.apps.nbu.files/com.google.android.apps.nbu.files.home.HomeActivity}" drawable="files_by_google" name="Files by Google"/>
A general template is as follows:
<item component="ComponentInfo{[PACKAGE_NAME]/[APP_ACIVITY_NAME]}" drawable="[DRAWABLE NAME]" name="[APP NAME]"/>

Done! You're ready to open a pull request. Please set
develop
as the base branch.
- Connect your Android device or emulator to your laptop/desktop PC that has
adb
installed (see this tutorial for more information) and open the app whose details you want to inspect, e.g. Telegram. - Open a new Command Prompt or Terminal window and input
adb devices
. - Finally, type the below-given command to get the information about the currently open application.
For Mac or Linux:
adb shell dumpsys window | grep 'mCurrentFocus'
For Windows:
adb shell dumpsys window | find "mCurrentFocus"
The part before the /
character in the above image, i.e. org.telegram.messenger
, is the package name ([PACKAGE_NAME]
). The part after it, i.e. org.telegram.messenger.DefaultIcon
, is the activity name ([APP_ACIVITY_NAME]
).
- Download IconRequest: Google Play • GitHub.
- Launch IconRequest and tap one of the options:
- UPDATE EXISTING — to copy packages with activities. How to request icons, 25s video.
- REQUEST NEW — to save icon images and packages with activities. This option is better if you are creating icons.
- Select the apps for which youʼd like to request or make icons.
- Copy, save or share.
- Download the Icon Pusher app.
- Launch the app.
- Select the icon(s) you want to upload or select all by pressing the square in the top right. Then press "Send".
- View the packages with the activities for each app on the Icon Pusher website. Please make sure the
drawable="[DRAWABLE NAME]"
matches the icon SVG file name.
While adding icons is the main focus for most contributors, code-related contributions are welcome.
To build Lawnicons, select the appDebug
build variant.
Here are a few contribution tips:
- The
app
module contains most of Lawnicons' core code, while thesvg-processor
module contains the code that converts the SVGs inside thesvgs
folder into Android Drawables. Generally, theapp
module is where you should make most of your contributions. - You can use either Java or, preferably, Kotlin.
- Make sure your code is logical and well formatted. If using Kotlin, see "Coding conventions" in the Kotlin documentation.
- Set
develop
as the base branch for pull requests. - Significant changes to the UI should be discussed on our Lawnchair's Telegram group chat. Generally, we want to keep things clean and simple.
