📜 Description

Adds SentryAndroidOptions.logcatLogsEnabled, defaulting to false, and the io.sentry.logcat.logs.enabled Android manifest key.

SentryLogcatAdapter now requires both this local opt-in and the existing aggregate core Logs flag before forwarding Logcat calls as Sentry Logs. The local check runs before throwable and message processing. Breadcrumb creation and the original Android Log invocation remain unchanged.

💡 Motivation and Context

Automatic Logcat instrumentation needs an explicit local opt-in before the aggregate core Logs flag can be removed. This prevents instrumented Android applications from unexpectedly forwarding Logcat output when core Logs capture becomes available without a global enable flag.

💚 How did you test it?

• ./gradlew spotlessApply apiDump
• ./gradlew :sentry-android-core:testReleaseUnitTest
• Added tests for Java and manifest opt-in, default-disabled behavior, and independent breadcrumb and Android Log calls
• Preserved coverage for Logcat levels, throwable bodies, and origin

📝 Checklist

• I added GH Issue ID & Linear ID
• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

🔮 Next steps

Add the Spring Boot Logback opt-in before removing the aggregate core Logs flag.
