Android build system and deployment patterns

Security Scan

Instruction-only Android build/deploy snippets that do not request credentials, installs, or unrelated privileges — content is coherent with the stated purpose.

Purpose & Capability

Name/description match the content: ADB, Gradle, Compose, and manifest guidance are appropriate for an Android build & deploy skill. No unrelated binaries, env vars, or services are requested.

Instruction Scope

SKILL.md contains targeted developer commands and code snippets; it does not instruct reading of unrelated files, harvesting environment variables, or sending data to external endpoints.

Install Mechanism

No install spec present (instruction-only), so nothing is written to disk or fetched during install.

Credentials

No environment variables, credentials, or config paths are required — requests are proportional to the stated purpose.

Persistence & Privilege

always is false and model invocation is allowed (the platform default). The skill does not request persistent or elevated privileges beyond normal agent invocation.

Assessment

This skill is instruction-only and appears coherent and low-risk: it provides Android developer commands and config snippets and does not request credentials or install code. Before using, ensure you trust the skill owner and review any commands the agent runs (e.g., adb commands will interact with connected devices). If you do not want the agent to run system commands or access devices, avoid granting the agent environment/tool access that would execute these snippets.

Android Build & Deploy

ADB Essentials

# Debug builds require -t flag (agents forget this)
adb install -r -t app-debug.apk

# Filter logcat for app + errors only
adb logcat -s "YourApp:*" "*:E"

Gradle Critical Fixes

android {
    compileSdk 35
    defaultConfig {
        targetSdk 35  // MUST match or Play Console rejects
        multiDexEnabled true  // Required for 64K+ methods
    }
}

dependencies {
    // BOM prevents Compose version conflicts
    implementation platform('androidx.compose:compose-bom:2024.12.01')
}

Compose State Errors

// WRONG - recomputed every recomposition
val filtered = items.filter { it.isValid }

// CORRECT - remember expensive operations  
val filtered = remember(items) { items.filter { it.isValid } }

// WRONG - state resets on recomposition
var count by mutableStateOf(0)

// CORRECT - remember state
var count by remember { mutableStateOf(0) }

AndroidManifest Pitfall

<!-- Declare camera optional or Play Console auto-requires it -->
<uses-feature android:name="android.hardware.camera" android:required="false" />
