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 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

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

What to determine:

Question	Impact
build.gradle.kts present?	Use Kotlin DSL syntax in all examples
minSdk < 26?	Note Session Replay requires API 26+ — silent no-op below that
Compose detected?	Recommend sentry-compose-android and Compose-specific masking
OkHttp present?	Recommend sentry-okhttp interceptor or Gradle plugin bytecode auto-instrumentation
Room/SQLite present?	Recommend sentry-android-sqlite or plugin bytecode instrumentation
Timber present?	Recommend sentry-android-timber integration
Jetpack Navigation?	Recommend sentry-android-navigation for screen tracking
Already has SentryAndroid.init()?	Skip install, jump to feature config
Application subclass exists?	That's where SentryAndroid.init() goes

---

Phase 2: Recommend

Present a concrete recommendation based on what you found. Don't ask open-ended questions — lead with a proposal:

Recommended (core coverage — always set up these):

• ✅ Error Monitoring — captures uncaught exceptions, ANRs, and native NDK crashes automatically
• ✅ Tracing — auto-instruments Activity lifecycle, app start, HTTP requests, and database queries
• ✅ Session Replay — records screen captures and user interactions for debugging (API 26+)

Optional (enhanced observability):

• ⚡ Profiling — continuous UI profiling (recommended) or transaction-based sampling
• ⚡ Logging — structured logs via Sentry.logger(), with optional Timber bridge
• ⚡ User Feedback — collect user-submitted bug reports from inside the app

Recommendation logic:

Feature	Recommend when...
Error Monitoring	Always — non-negotiable baseline for any Android app
Tracing	Always for Android — app start time, Activity lifecycle, network latency matter
Session Replay	User-facing production app on API 26+; visual debugging of user issues
Profiling	Performance-sensitive apps, startup time investigations, production perf analysis
Logging	App uses structured logging or you want log-to-trace correlation in Sentry
User Feedback	Beta or customer-facing app where you want user-submitted bug reports

Propose: "For your [Kotlin / Java] Android app (minSdk X), I recommend setting up Error Monitoring + Tracing + Session Replay. Want me to also add Profiling and Logging?"

---

Phase 3: Guide

Determine Your Setup Path

Project type	Recommended setup	Complexity
New project, no existing Sentry	Gradle plugin (recommended)	Low — plugin handles most config
Existing project, no Sentry	Gradle plugin or manual init	Medium — add dependency + Application class
Manual full control	SentryAndroid.init() in Application	Medium — explicit config, most flexible

Option 1: Wizard (Recommended)

You need to run this yourself — the wizard opens a browser for login and requires interactive input that the agent can't handle. Copy-paste into your terminal:

npx @sentry/wizard@latest -i android

It handles login, org/project selection, Gradle plugin setup, dependency installation, DSN configuration, and ProGuard/R8 mapping upload.

Once it finishes, come back and skip to Verification.

If the user skips the wizard, proceed with Option 2 (Manual Setup) below.

---

Option 2: Manual Setup

Path A: Gradle Plugin (Recommended)

The Sentry Gradle plugin is the easiest setup path. It:

• Uploads ProGuard/R8 mapping files automatically on release builds
• Injects source context into stack frames
• Optionally instruments OkHttp, Room/SQLite, File I/O, Compose navigation, and android.util.Log via bytecode transforms (zero source changes)

Step 1 — Add the plugin to build.gradle[.kts] (project-level)

Groovy DSL (build.gradle):

plugins {
    id "io.sentry.android.gradle" version "6.1.0" apply false
}

Kotlin DSL (build.gradle.kts):

plugins {
    id("io.sentry.android.gradle") version "6.1.0" apply false
}

Step 2 — Apply plugin + add dependencies in app/build.gradle[.kts]

Groovy DSL:

plugins {
    id "com.android.application"
    id "io.sentry.android.gradle"
}

android {
    // ...
}

dependencies {
    // Use BOM for consistent versions across sentry modules
    implementation platform("io.sentry:sentry-bom:8.33.0")
    implementation "io.sentry:sentry-android"

    // Optional integrations (add what's relevant):
    // implementation "io.sentry:sentry-android-timber"     // Timber bridge
    // implementation "io.sentry:sentry-android-fragment"   // Fragment lifecycle tracing
    // implementation "io.sentry:sentry-compose-android"    // Jetpack Compose support
    // implementation "io.sentry:sentry-android-navigation"  // Jetpack Navigation
    // implementation "io.sentry:sentry-okhttp"             // OkHttp interceptor
    // implementation "io.sentry:sentry-android-sqlite"     // Room/SQLite tracing
    // implementation "io.sentry:sentry-kotlin-extensions"  // Coroutine context propagation
}

sentry {
    org = "YOUR_ORG_SLUG"
    projectName = "YOUR_PROJECT_SLUG"
    authToken = System.getenv("SENTRY_AUTH_TOKEN")

    // Enable auto-instrumentation via bytecode transforms (no source changes needed)
    tracingInstrumentation {
        enabled = true
        features = [InstrumentationFeature.DATABASE, InstrumentationFeature.FILE_IO,
                    InstrumentationFeature.OKHTTP, InstrumentationFeature.COMPOSE]
    }

    // Upload ProGuard mapping and source context on release
    autoUploadProguardMapping = true
    includeSourceContext = true
}

Kotlin DSL (app/build.gradle.kts):

plugins {
    id("com.android.application")
    id("io.sentry.android.gradle")
}

dependencies {
    implementation(platform("io.sentry:sentry-bom:8.33.0"))
    implementation("io.sentry:sentry-android")

    // Optional integrations:
    // implementation("io.sentry:sentry-android-timber")
    // implementation("io.sentry:sentry-android-fragment")
    // implementation("io.sentry:sentry-compose-android")
    // implementation("io.sentry:sentry-android-navigation")
    // implementation("io.sentry:sentry-okhttp")
    // implementation("io.sentry:sentry-android-sqlite")
    // implementation("io.sentry:sentry-kotlin-extensions")
}

sentry {
    org = "YOUR_ORG_SLUG"
    projectName = "YOUR_PROJECT_SLUG"
    authToken = System.getenv("SENTRY_AUTH_TOKEN")

    tracingInstrumentation {
        enabled = true
        features = setOf(
            InstrumentationFeature.DATABASE,
            InstrumentationFeature.FILE_IO,
            InstrumentationFeature.OKHTTP,
            InstrumentationFeature.COMPOSE,
        )
    }

    autoUploadProguardMapping = true
    includeSourceContext = true
}

Step 3 — Initialize Sentry in your Application class

If you don't have an Application subclass, create one:

// MyApplication.kt
import android.app.Application
import io.sentry.SentryLevel
import io.sentry.android.core.SentryAndroid
import io.sentry.android.replay.SentryReplayOptions

class MyApplication : Application() {
    override fun onCreate() {
        super.onCreate()

        SentryAndroid.init(this) { options ->
            options.dsn = "YOUR_SENTRY_DSN"

            // Tracing — lower to 0.1–0.2 in high-traffic production
            options.tracesSampleRate = 1.0

            // Profiling — use continuous UI profiling (recommended, SDK ≥ 8.7.0)
            options.profileSessionSampleRate = 1.0

            // Session Replay (API 26+ only; silent no-op below API 26)
            options.sessionReplay.sessionSampleRate = 0.1    // 10% of all sessions
            options.sessionReplay.onErrorSampleRate = 1.0    // 100% on error

            // Structured logging
            options.logs.isEnabled = true

            // Environment
            options.environment = BuildConfig.BUILD_TYPE
        }
    }
}

Java equivalent:

// MyApplication.java
import android.app.Application;
import io.sentry.android.core.SentryAndroid;

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        SentryAndroid.init(this, options -> {
            options.setDsn("YOUR_SENTRY_DSN");
            options.setTracesSampleRate(1.0);
            options.setProfileSessionSampleRate(1.0);
            options.getSessionReplay().setSessionSampleRate(0.1);
            options.getSessionReplay().setOnErrorSampleRate(1.0);
            options.getLogs().setEnabled(true);
            options.setEnvironment(BuildConfig.BUILD_TYPE);
        });
    }
}

Step 4 — Register Application in AndroidManifest.xml

<application
    android:name=".MyApplication"
    ... >

---

Path B: Manual Setup (No Gradle Plugin)

Use this if you can't use the Gradle plugin (e.g., non-standard build setups).

Step 1 — Add dependency in app/build.gradle[.kts]

dependencies {
    implementation(platform("io.sentry:sentry-bom:8.33.0"))
    implementation("io.sentry:sentry-android")
}

Step 2 — Initialize in Application class (same as Path A, Step 3)

Step 3 — Configure ProGuard/R8 manually

The Sentry SDK ships a ProGuard rules file automatically. For manual mapping upload, install sentry-cli and add to your CI:

sentry-cli releases files "my-app@1.0.0+42" upload-proguard \
  --org YOUR_ORG --project YOUR_PROJECT \
  app/build/outputs/mapping/release/mapping.txt

---

Quick Reference: Full-Featured SentryAndroid.init()

SentryAndroid.init(this) { options ->
    options.dsn = "YOUR_SENTRY_DSN"

    // Environment and release
    options.environment = BuildConfig.BUILD_TYPE     // "debug", "release", etc.
    options.release = "${BuildConfig.APPLICATION_ID}@${BuildConfig.VERSION_NAME}+${BuildConfig.VERSION_CODE}"

    // Tracing — sample 100% in dev, lower to 10–20% in production
    options.tracesSampleRate = 1.0

    // Continuous UI profiling (recommended over transaction-based)
    options.profileSessionSampleRate = 1.0

    // Session Replay (API 26+; silent no-op on API 21–25)
    options.sessionReplay.sessionSampleRate = 0.1
    options.sessionReplay.onErrorSampleRate = 1.0
    options.sessionReplay.maskAllText = true         // mask text for privacy
    options.sessionReplay.maskAllImages = true       // mask images for privacy

    // Structured logging
    options.logs.isEnabled = true

    // Error enrichment
    options.isAttachScreenshot = true                // capture screenshot on error
    options.isAttachViewHierarchy = true             // attach view hierarchy JSON

    // ANR detection (5s default; watchdog + ApplicationExitInfo API 30+)
    options.isAnrEnabled = true

    // NDK native crash handling (enabled by default)
    options.isEnableNdk = true

    // Send PII: IP address, user data
    options.sendDefaultPii = true

    // Trace propagation (backend distributed tracing)
    options.tracePropagationTargets = listOf("api.yourapp.com", ".*\\.yourapp\\.com")

    // Verbose logging — disable in production
    options.isDebug = BuildConfig.DEBUG
}

You can also configure DSN and many options via AndroidManifest.xml meta-data:

<application>
    <meta-data android:name="io.sentry.dsn" android:value="YOUR_DSN" />
    <meta-data android:name="io.sentry.traces-sample-rate" android:value="1.0" />
    <meta-data android:name="io.sentry.environment" android:value="production" />
    <meta-data android:name="io.sentry.anr.enable" android:value="true" />
    <meta-data android:name="io.sentry.attach-screenshot" android:value="true" />
    <meta-data android:name="io.sentry.attach-view-hierarchy" android:value="true" />
</application>

⚠️ Manifest meta-data is a convenient alternative but does not support the full option set. For complex configuration (session replay, profiling, hooks), use SentryAndroid.init().

---

Verification

After setup, verify Sentry is receiving events:

Test error capture:

// In an Activity or Fragment
try {
    throw RuntimeException("Sentry Android SDK test")
} catch (e: Exception) {
    Sentry.captureException(e)
}

Test tracing:

val transaction = Sentry.startTransaction("test-task", "task")
val span = transaction.startChild("test-span", "description")
span.finish()
transaction.finish()

Test structured logging (SDK ≥ 8.12.0):

Sentry.logger().info("Sentry logging test")
Sentry.logger().error("Error log test", Exception("test error"))

Check the Sentry dashboard:

• Issues → your test exception should appear within seconds
• Traces → look for test-task transaction with child span
• Replays → session recording visible after app interaction (requires API 26+)
• Logs → structured log entries visible under Logs tab

If nothing appears:

1. Set options.isDebug = true — SDK logs to Logcat
2. Verify DSN is correct and matches your Sentry project
3. Check that your Application class is registered in AndroidManifest.xml as android:name
4. Confirm the device/emulator has internet connectivity
5. For NDK crashes, ensure isEnableNdk = true (default) and build with NDK support

---

Phase 4: Cross-Link

After completing Android setup, check for a backend or web frontend missing Sentry coverage:

# Adjacent backend directories
ls ../backend ../server ../api 2>/dev/null
cat ../go.mod 2>/dev/null | head -3
cat ../requirements.txt ../pyproject.toml 2>/dev/null | head -5
cat ../Gemfile 2>/dev/null | head -3
ls ../backend/package.json ../server/package.json 2>/dev/null

# iOS counterpart app
ls ../ios ../YourApp-iOS 2>/dev/null
find .. -maxdepth 3 -name "*.xcodeproj" 2>/dev/null | head -3

If a backend or related platform exists without Sentry, suggest the matching skill:

Detected	Suggest skill
Go backend (go.mod)	sentry-go-sdk
Python backend (requirements.txt, pyproject.toml)	sentry-python-sdk
Ruby backend (Gemfile)	sentry-ruby-sdk
Node.js backend	@sentry/node — see docs.sentry.io/platforms/javascript/guides/express/
iOS app (.xcodeproj)	sentry-cocoa-sdk
React Native (package.json with react-native)	sentry-react-native-sdk
React / Next.js web	sentry-react-sdk or sentry-nextjs-sdk

Distributed tracing setup — if the backend skill is added, configure tracePropagationTargets in Android to propagate trace context to your API:

options.tracePropagationTargets = listOf(
    "api.yourapp.com",
    ".*\\.yourapp\\.com"
)

This links mobile transactions to backend traces in the Sentry waterfall view.

---

Troubleshooting

Issue	Solution
Events not appearing in Sentry	Set isDebug = true, check Logcat for SDK errors; verify DSN is correct and matches your project
SentryAndroid.init() not called	Confirm android:name=".MyApplication" is set in AndroidManifest.xml; Application class not abstract
Gradle plugin not found	Add the plugin to project-level build.gradle.kts first, then apply false; verify version 6.1.0
ProGuard mapping not uploading	Set SENTRY_AUTH_TOKEN env var; ensure autoUploadProguardMapping = true in sentry {} block
NDK crashes not captured	Verify isEnableNdk = true (default); ensure project has NDK configured in android.ndkVersion
ANR reported in debugger	Set isAnrReportInDebug = false (default); ANR watchdog fires when debugger pauses threads
Session replay not recording	Requires API 26+; verify sessionSampleRate > 0 or onErrorSampleRate > 0; check Logcat for replay errors
Session replay shows blank screen	PixelCopy (default) requires hardware acceleration; try SentryReplayOptions.screenshotQuality = CANVAS
Replay masking misaligned	Views with translationX/Y or clipToPadding=false can offset masks; report to github.com/getsentry/sentry-java
beforeSend not firing	beforeSend only intercepts managed (Java/Kotlin) events; NDK native crashes bypass it
OkHttp spans not appearing	Add SentryOkHttpInterceptor to your OkHttpClient, or use Gradle plugin OKHTTP bytecode instrumentation
Spans not attached to transaction	Ensure TransactionOptions().setBindToScope(true) when starting transaction; child spans look for scope root
Tracing not recording	Verify tracesSampleRate > 0; Activity instrumentation requires isEnableAutoActivityLifecycleTracing = true (default)
Continuous profiling not working	SDK ≥ 8.7.0 required; API 22+ required; set profileSessionSampleRate > 0; don't also set profilesSampleRate
Both profiling modes set	profilesSampleRate and profileSessionSampleRate are mutually exclusive — use only one
TTFD spans missing	Set isEnableTimeToFullDisplayTracing = true and call Sentry.reportFullyDisplayed() when screen is ready
Kotlin coroutine scope lost	Add sentry-kotlin-extensions dependency; use Sentry.cloneMainContext() to propagate trace context
Release build stack traces unreadable	ProGuard mapping not uploaded; confirm Gradle plugin autoUploadProguardMapping = true and auth token set
Source context not showing in Sentry	Enable includeSourceContext = true in sentry {} block (Gradle plugin required)
BOM version conflict	Use implementation(platform("io.sentry:sentry-bom:8.33.0")) and omit versions from all other io.sentry:* entries
SENTRY_AUTH_TOKEN exposed	Auth token is build-time only — never pass it to SentryAndroid.init() or embed in the APK
