Problem Statement

Submitting on behalf of a customer:

We have received feedback from our users regarding instances of unresponsiveness in our application. As such, we are keen on leveraging the capabilities of Sentry’s Electron SDK to implement ANR detection.

The Electron SDK currently does not detect non-responsiveness/ANRs.

Prior work:

• Android ANR: https://docs.sentry.io/platforms/android/configuration/app-not-respond/
• Unity ANR: https://docs.sentry.io/platforms/unity/configuration/app-not-responding/
• App Hangs for iOS: https://docs.sentry.io/platforms/apple/configuration/app-hangs/

Solution Brainstorm

We are interested in understanding whether the SDK offers built-in capabilities to detect and handle application unresponsiveness.

An internal chat with Abhi on slack notes that we may be able to do watchdog approach that monitors the main thread but it’ll have to investigated more.
