Sentry Android SDK

Opinionated wizard that scans your Android project and guides you through complete Sentry setup — error monitoring, tracing, profiling, session replay, logging, and more.

Invoke This Skill When

• User asks to "add Sentry to Android" or "set up Sentry" in an Android app
• User wants error monitoring, crash reporting, ANR detection, tracing, profiling, session replay, or logging in Android
• User mentions sentry-android, io.sentry:sentry-android, mobile crash tracking, or Sentry for Kotlin/Java Android
• User wants to monitor native (NDK) crashes, application not responding (ANR) events, or app startup performance

Note: SDK versions and APIs below reflect current Sentry docs at time of writing (io.sentry:sentry-android:8.33.0, Gradle plugin 6.1.0). Always verify against docs.sentry.io/platforms/android/ before implementing.

Phase 1: Detect

Run these commands to understand the project before making any recommendations:

# Detect project structure and build system
ls build.gradle build.gradle.kts settings.gradle settings.gradle.kts 2>/dev/null

# Check AGP version and existing Sentry
grep -r '"com.android.application"' build.gradle* app/build.gradle* 2>/dev/null | head -3
grep -ri sentry build.gradle* app/build.gradle* 2>/dev/null | head -10

# Check app-level build file (Groovy vs KTS)
ls app/build.gradle app/build.gradle.kts 2>/dev/null

# Detect Gradle version catalog (libs.versions.toml) — modern AGP projects
ls gradle/libs.versions.toml 2>/dev/null

# Check for existing Sentry entries in the version catalog
grep -iE 'sentry|io\.sentry' gradle/libs.versions.toml 2>/dev/null | head -10

# Check if build files reference the catalog (alias/libs.* usage)
grep -E 'alias\(libs\.|libs\.[a-zA-Z]' build.gradle build.gradle.kts app/build.gradle app/build.gradle.kts 2>/dev/null | head -5

# Detect Kotlin vs Java
find app/src/main -name "*.kt" 2>/dev/null | head -3
find app/src/main -name "*.java" 2>/dev/null | head -3

# Check minSdk, targetSdk
grep -E 'minSdk|targetSdk|compileSdk|minSdkVersion|targetSdkVersion' app/build.gradle app/build.gradle.kts 2>/dev/null | head -6

# Detect Jetpack Compose
grep -E 'compose|androidx.compose' app/build.gradle app/build.gradle.kts 2>/dev/null | head -5

# Detect OkHttp (popular HTTP client — has dedicated integration)
grep -E 'okhttp|retrofit' app/build.gradle app/build.gradle.kts 2>/dev/null | head -3

# Detect Room or SQLite
grep -E 'androidx.room|androidx.sqlite' app/build.gradle app/build.gradle.kts 2>/dev/null | head -3

# Detect Timber (logging library)
grep -E 'timber' app/build.gradle app/build.gradle.kts 2>/dev/null | head -3

# Detect Jetpack Navigation
grep -E 'androidx.navigation' app/build.gradle app/build.gradle.kts 2>/dev/null | head -3

# Detect Apollo (GraphQL)
grep -E 'apollo' app/build.gradle app/build.gradle.kts 2>/dev/null | head -3

# Check existing Sentry initialization
grep -r "SentryAndroid.init\|io.sentry.Sentry" app/src/ 2>/dev/null | head -5

# Check Application class
find app/src/main -name "*.kt" -o -name "*.java" 2>/dev/null | xargs grep -l "Application()" 2>/dev/null | head -3

# Adjacent backend (for cross-linking)
ls ../backend ../server ../api 2>/dev/null
find .. -maxdepth 2 \( -name "go.mod" -o -name "requirements.txt" -o -name "Gemfile" \) 2>/dev/null | grep -v node_modules | head -5
