feat(feedback): Add screenshot attachment button to user feedback widget by markushi · Pull Request #5828 · getsentry/sentry-java

markushi · 2026-07-23T16:46:15Z

📜 Description

Adds an "Add a screenshot" button to the Android user feedback form that opens the
androidx photo picker (ActivityResultContracts.PickVisualMedia, images only) and sends
the picked image as an attachment in the same envelope as the feedback.

Screen_recording_20260723_183244.mp4

New SentryFeedbackOptions: enableScreenshot (default true, matching the JS SDK),
addScreenshotButtonLabel, removeScreenshotButtonLabel, plus the
io.sentry.feedback.enable-screenshot manifest flag
androidx.activity:activity:1.8.2 is added as compileOnly — no new transitive
dependency; the button is hidden (with a warning log) when androidx.activity is missing
or the host Activity is not a ComponentActivity
The image is size-checked against maxAttachmentSize at pick time

💡 Motivation and Context

resolves: Add file attachment support to user feedback widget #5485

💚 How did you test it?

Unit tests + Manual testing.

I decided I'm always going to comment whenever we add new usages of this. Sorry to bring it up again.

How will we know that this feature is working in production if we swallow all errors?

Since we're dealing with images, files and attachments how we we know we aren't swallowing a permissions issue or OOM?

Lazy URI read may drop attachment

Medium Severity

The screenshot Attachment uses a lazy byteProvider that opens the photo-picker Uri later on the async transport/cache path. Picker URIs only grant temporary read access to the host activity, so if that access is gone before serialization, the attachment is dropped while feedback still reports success.

Bug: The maybeRegisterScreenshotPicker method lacks a guard to prevent re-registering the screenshot picker, which could cause a crash if onStart() is called multiple times.
_{Severity: MEDIUM}

Suggested Fix

In maybeRegisterScreenshotPicker, add a null check to ensure screenshotPicker is not already initialized before calling SentryFeedbackScreenshotPicker.register(). For example: if (screenshotPicker == null) { ... }.

Prompt for AI Agent

Review the code at the location below. A potential bug has been identified by an AI agent. Verify if this is a real issue. If it is, propose a fix; if not, explain why it's not valid. Location: sentry-android-core/src/main/java/io/sentry/android/core/SentryUserFeedbackForm.java#L415-L418 Potential issue: In `SentryUserFeedbackForm`, the `maybeRegisterScreenshotPicker` method is called from `onStart()` to register an activity result launcher. This registration uses a hardcoded key. The method lacks a defensive check to see if the `screenshotPicker` has already been initialized. While the `onStop()` method unregisters the launcher, it's possible in certain edge-case lifecycle scenarios for `onStart()` to be invoked twice without an intervening `onStop()`. This would lead to an attempt to register the same key again, causing an `IllegalStateException` and crashing the app.
