Gradle
The Sentry Android Gradle Plugin is an addition to the main Android and Hybrid SDKs (like React Native and Flutter) and offers seamless integration with the Gradle build system. It supports the following features:
- ProGuard/R8 mappings upload
- Java/Kotlin Source Context upload
- Native debug symbols and sources upload
- Auto-instrumentation tracing through bytecode manipulation
- Logcat breadcrumb logging
- Auto-installation of the Sentry Android SDK and its integrations
- External dependencies report
Using Gradle (Android Studio) in your app/build.gradle
add:
app/build.gradle
plugins {
id "com.android.application"
id "io.sentry.android.gradle" version "4.5.0"
}
The io.sentry.android.gradle
>= 3.0.0
requires Android Gradle Plugin >= 7.0.0. For older versions of the Android Gradle Plugin, use io.sentry.android.gradle:2.+
.
Set the auth token as an environment variable to be used when running your release build.
export SENTRY_AUTH_TOKEN=sntrys_YOUR_TOKEN_HERE
We expose the following configuration values directly in your app/build.gradle
:
import io.sentry.android.gradle.extensions.InstrumentationFeature
import io.sentry.android.gradle.instrumentation.logcat.LogcatLevel
sentry {
// Disables or enables debug log output, e.g. for for sentry-cli.
// Default is disabled.

// The slug of the Sentry organization to use for uploading proguard mappings/source contexts.
org = "example-org"
// The slug of the Sentry project to use for uploading proguard mappings/source contexts.

// Default is disabled.
includeNativeSources = false

// Enable or disable the tracing instrumentation.
// Does auto instrumentation for specified features through bytecode manipulation.
// Default is enabled.
tracingInstrumentation {

// Specifies a set of instrumentation features that are eligible for bytecode manipulation.
// Defaults to all available values of InstrumentationFeature enum class.
features = [InstrumentationFeature.DATABASE, InstrumentationFeature.FILE_IO, InstrumentationFeature.OKHTTP, InstrumentationFeature.COMPOSE]
// Enable or disable logcat instrumentation through bytecode manipulation.
// Default is enabled.

// the .class suffix isn't included in the pattern matching.
//
// Example usage:
// ```

// ```
//
// Only supported when using Android Gradle plugin (AGP) version 7.4.0 and above.
excludes = []
}

// Default is enabled.
// Only available v3.1.0 and above.

// Specifies a version of the sentry-android SDK and fragment, timber and okhttp integrations.
//
// This is also useful, when you have the sentry-android SDK already included into a transitive dependency/module and want to
// align integration versions with it (if it's a direct dependency, the version will be inferred).
//

//
// Defaults to the latest published Sentry version.
sentryVersion = '7.8.0'

}
Now when you build your app, the plugin will upload the ProGuard/R8 mappings, source bundle, and native symbols as you configured them to Sentry.
You can specify which variant/flavor/build-type should be ignored by Sentry in your app/build.gradle
file:
sentry {
// List the build types that should be ignored (e.g. "release").
ignoredBuildTypes = ["release"]
// List the build flavors that should be ignored (e.g. "production").
ignoredFlavors = ["production"]
// List the build variant that should be ignored (e.g. "productionRelease").
ignoredVariants = ["productionRelease"]
}
The plugin will automatically generate appropriate ProGuard mapping files and upload them when you run gradle assemble{BuildVariant}
. For example, assembleRelease
. Release is the default, but the plugin works for others as long as you've enabled ProGuard/R8. The credentials for the upload step are defined in the Gradle extension above or loaded from a sentry.properties
file in your project.
To use Guardsquare's ProGuard or DexGuard tooling, you'll have to enable the dexguardEnabled
flag. Learn more in the full sentry-cli
documentation.
Instead of providing your credentials via the Gradle extension, you can create a sentry.properties
file with the following content under your app
module:
defaults.project=example-project
defaults.org=example-org
auth.token=sntrys_YOUR_TOKEN_HERE
You can find your authentication token on the Organization Auth Tokens settings page. For more information about the available configuration options, check out the full sentry-cli documentation.
The plugin will automatically discover and upload Native debug symbols and sources when you run gradle assemble{BuildVariant}
. The {BuildVariant}
must be a non-debuggable build type, for example Release
. The credentials for the upload step are loaded via environment variables or from a sentry.properties
file in your project root.
Learn more in the full sentry-cli documentation.
At the very minimum, you will need something similar to:
defaults.project=example-project
defaults.org=example-org
auth.token=sntrys_YOUR_TOKEN_HERE
You can find your authentication token on the Sentry API page. For more information about the available configuration options, check out the full sentry-cli documentation.
This plugin can automatically upload your source code to Sentry so it is shown as part of the stack traces.
sentry {
includeSourceContext = true
}
Checkout the full documentation on Source Context for more details.
The plugin uses the bytecode manipulation framework to inject a code snippet that starts and finishes a span for common operations that can cause performance bottlenecks. This way potentially heavy operations are automatically measured without the need to manually instrument them.
For this data to be captured, you must enable performance monitoring.
The plugin supports the following features for auto-instrumentation:
enum class InstrumentationFeature {
/**
* When enabled the SDK will create spans for any CRUD operation performed by 'androidx.sqlite'
* and 'androidx.room'. This feature uses bytecode manipulation.
*
* Requires sentry-android SDK version 4.0.0 and above
*/
DATABASE,
/**
* When enabled the SDK will create spans for [java.io.FileInputStream],
* [java.io.FileOutputStream], [java.io.FileReader], [java.io.FileWriter].
* This feature uses bytecode manipulation and replaces the above
* mentioned classes with Sentry-specific implementations.
*
* Requires sentry-android SDK version 5.5.0 and above
*/
FILE_IO,
/**
* When enabled the SDK will create spans for outgoing network requests and attach
* sentry-trace-header for distributed tracing.
* This feature uses bytecode manipulation and attaches SentryOkHttpInterceptor to all OkHttp
* clients in the project.
*
* Requires sentry-android SDK version 5.0.0 and above.
* Only available v3.1.0 and above of the Sentry Android Gradle plugin.
*/
OKHTTP,
/**
* When enabled the SDK will create breadcrumbs when navigating
* using [androidx.navigation.NavController].
* This feature uses bytecode manipulation and adds an OnDestinationChangedListener to all
* navigation controllers used in Jetpack Compose.
*/
COMPOSE

The plugin offers the automated installation feature of the Sentry Android SDK and the Fragment, Timber, OkHttp, and Jetpack Compose integrations. Starting with version 3.1.0, the feature is enabled by default, so you don't need to add any dependencies — you just use the Sentry Gradle plugin.
The plugin algorithm does the following when defining dependency versions:
Check if the module/app has a direct dependency on the Sentry Android SDK:
If yes, then use the version of the direct dependency.
If no, then automatically add the sentry-android dependency with the specified
sentryVersion
from the plugin configuration (defaults to the latest published SDK version).
Check if the module/app has a direct dependency on any of the integrations (Fragment, Timber, or OkHttp):
If yes, then keep the current version of the direct dependency.
If no, then automatically add the integration dependency with the version of the Sentry Android SDK inferred from above.
If there are transitive dependencies on any of the integrations or the Sentry Android SDK, then their versions are not considered. However, if the versions are higher than those bundled with the Sentry Gradle plugin, Gradle will choose them instead.
