Add or change XML layouts, styles, and string resources. An agent skill from Adyen/adyen-android.

  • Tasks that involve Android development
  • SKILL.md covers Usage, Layouts and styles, Strings and Important
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Android UI Resources is an agent skill from Adyen/adyen-android. Add or change XML layouts, styles, and string resources.

Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Android development. It works with Android. The repository describes itself as: Adyen Android Drop-in and Components. The licence is MIT.

When your agent uses it

  • Tasks that involve Android development

Example prompts

  • “/android-ui-resources”

What it can do on your machine

Read from SKILL.md and the folder at commit 475ca6a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are xml and kotlin).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Android UI Resources loads about 709 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 299 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~709

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Add or change XML layouts, styles, and string resources.

android-ui-resources

Add or change XML resources in the Adyen Android SDK without breaking merchant themes or shopper localization.

Usage

Invoke this skill when touching a module's res/ directory: layouts, styles, or strings. These rules apply to the XML-based views (v5 and the modules that still use them); Compose UI follows the theme system in docs/v6/theme.md instead.

Search the codebase for a similar existing view before writing a new one — the correct style, attribute, and string pattern almost always already exists somewhere.

Layouts and styles

Give every new view a style

Merchants customize our UI through styles, so a view without one cannot be customized. Follow the naming of the surrounding styles.

Use theme-safe attributes

Only reference attributes that are guaranteed to exist in a merchant's theme. Default Material attributes are safe; framework attributes often are not.

  • Avoid ?android:attr/textColor — it may be undefined in a merchant theme and crashes at inflation time.
  • Prefer ?attr/colorOnSurface and the other Material defaults.
Keep the style hierarchy complete

A style like AdyenCheckout.Image.Logo.Large requires every ancestor to exist as a declared style, even if empty. Without them, merchants who override a parent style hit errors.

xml
<!-- All three must exist, even though the parents are empty -->
<style name="AdyenCheckout.Image" />
<style name="AdyenCheckout.Image.Logo" parent="AdyenCheckout.Image" />
<style name="AdyenCheckout.Image.Logo.Large" parent="AdyenCheckout.Image.Logo">
    <item name="android:layout_width">48dp</item>
    <item name="android:layout_height">48dp</item>
</style>

Strings

Always use the shopper locale

Components must render in the shopper locale, not the device locale. This covers every displayed string: labels, hints, errors, and content descriptions. Resolve them through localizedContext, never through the plain view or activity context.

kotlin
val label = localizedContext.getString(R.string.checkout_card_holder_name_label)

Search for localizedContext and localizedContext.getString for examples.

Set strings through styles, not layouts

Text belongs in the style so merchants can override it. In a layout, use tools:text for preview only:

xml
<TextView
    style="@style/AdyenCheckout.TextView.Title"
    tools:text="@string/checkout_card_holder_name_label" />

Do not use android:text in a component layout.

Important

  • Adding or changing a merchant-visible string or style is merchant-observable: use a feature/ or fix/ branch prefix, not chore/.
  • When strings change, confirm translations are present for all supported locales.
