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

What to determine:

Question	Impact
`build.gradle.kts` present?	Use Kotlin DSL syntax in all examples
`gradle/libs.versions.toml` present?	Add Sentry to the version catalog; reference via `libs.*` in build files
Catalog already has `sentry` entries?	Reuse the existing version ref; don't duplicate or hardcode versions
`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

Using a Gradle Version Catalog (`gradle/libs.versions.toml`)

If Phase 1 detected gradle/libs.versions.toml, add Sentry to the catalog first, then reference it from your build files. This keeps versions centralized and matches modern AGP project conventions.

Step 1 — Add entries to gradle/libs.versions.toml

[versions]
sentry = "8.33.0"
sentryGradlePlugin = "6.1.0"
 
[libraries]
sentry-android = { module = "io.sentry:sentry-android", version.ref = "sentry" }
sentry-bom = { module = "io.sentry:sentry-bom", version.ref = "sentry" }
# Optional integrations — add only the ones your project uses:
sentry-android-timber = { module = "io.sentry:sentry-android-timber" }
sentry-android-fragment = { module = "io.sentry:sentry-android-fragment" }
sentry-compose-android = { module = "io.sentry:sentry-compose-android" }
sentry-android-navigation = { module = "io.sentry:sentry-android-navigation" }
sentry-okhttp = { module = "io.sentry:sentry-okhttp" }
sentry-android-sqlite = { module = "io.sentry:sentry-android-sqlite" }
sentry-kotlin-extensions = { module = "io.sentry:sentry-kotlin-extensions" }
 
[plugins]
sentry-android-gradle = { id = "io.sentry.android.gradle", version.ref = "sentryGradlePlugin" }

Note: Optional integration entries omit version.ref — their versions come from the BOM at resolution time. Only sentry-bom needs the version ref. If the catalog already defines a sentry version, reuse it instead of adding a duplicate entry.

Step 2 — Reference the catalog from build.gradle[.kts]

Project-level build.gradle.kts:

plugins {
    alias(libs.plugins.sentry.android.gradle) apply false
}

App-level app/build.gradle.kts:

plugins {
    id("com.android.application")
    alias(libs.plugins.sentry.android.gradle)
}
 
dependencies {
    implementation(platform(libs.sentry.bom))
    implementation(libs.sentry.android)
    // implementation(libs.sentry.okhttp)
    // implementation(libs.sentry.compose.android)
}

Groovy DSL (app/build.gradle) equivalent:

plugins {
    id "com.android.application"
    alias libs.plugins.sentry.android.gradle
}
 
dependencies {
    implementation platform(libs.sentry.bom)
    implementation libs.sentry.android
}

Then continue with the sentry {} configuration block from Path A, Step 2 below. The rest of the setup (Application class init, manifest registration, verification) is identical.

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
}

`SENTRY_PROJECT`	Project slug	Used by Gradle plugin `sentry.projectName`
`SENTRY_RELEASE`	Release identifier	Falls back from `options.release`
`SENTRY_ENVIRONMENT`	Environment name	Falls back from `options.environment`

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:

Set options.isDebug = true — SDK logs to Logcat
Verify DSN is correct and matches your Sentry project
Check that your Application class is registered in AndroidManifest.xml as android:name
Confirm the device/emulator has internet connectivity
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
Version catalog alias unresolved	After editing `gradle/libs.versions.toml`, sync Gradle; alias names use `-` in TOML and `.` in build files (e.g., `sentry-android` → `libs.sentry.android`)
Duplicate Sentry version in catalog	Reuse the existing `[versions] sentry = "..."` entry; don't add a second key, and don't hardcode the version in `build.gradle` when the catalog is in use
`SENTRY_AUTH_TOKEN` exposed	Auth token is build-time only — never pass it to `SentryAndroid.init()` or embed in the APK
