Version

9.0.0

Steps to Reproduce

Install 9.0.0 or later version of Flutter Sentry on Android, try to initialize the SDK and try to log events on an Android device.

Expected Result

Sentry initializes correctly on Android with the latest stable 9.x.y releases, and our mobile clients can send events to Sentry.

Actual Result

Since upgrading to 9.0.0 (I tried 9.0.0-RC.3, 9.0.0, 9.1.0), initializing the Sentry SDK doesn't work for Android.

I might be missing something, as I'd not expect such a grave issue still present in the upgrade, but everything so far points towards it being an upgrade issue.

We get the following error when the Sentry SDK is initialized, and all subsequent calls to log events fails, too.

I tried it a couple of times, always failed with 9.x.y, and never with 8.14.2. AFAIK, there are no dependency caching issues, I tried to clean everything.

Are you willing to submit a PR?

No

hey @vincevargadev

are you using the Sentry Android Gradle Plugin as well?

[buenaflor]

Also would you mind sharing which dependencies you are using

[vincevargadev]

In /app/build.gradle.

plugins {
  // ...
    id "io.sentry.android.gradle" version "5.5.0"
}

[buenaflor]

Looks like that's the issue - the Sentry Android Gradle Plugin 5.5.0 automatically installs the Sentry Android SDK 8.11.1 which matches the error log you've posted. This conflicts with the Android SDK installed with Sentry Flutter

you need to disable it like so:

// in app/build.gradle
sentry {
    autoInstallation {
      enabled = false
    }
}
