[Invalid] Screenshot preview does not display cropped image

[davidhedlund]

Aftermath: Screenshot Tile does not display screenshot thumbnail previews, I just verified it (Legacy method, tested the Screenshot button from Android's Quick Menu. So I mixed up this issue with the hardware button method of taking screenshots, which uses Android’s built‑in screenshot tool that shows thumbnail previews.

Steps to reproduce

• Configuration
  • Make sure that "Legacy Method" is enabled
  • Subsequent actions:
    • Enable "Crop"
    • Set "Top px" to 100 px
    • Set "Bottom px" to 100 px
  • Add "Screenshot" to Android's Quick Menu
• Tap "Screenshot" from Android's Quick Menu
  • I didn't do this when I submitted the issue, I tapped the hardware buttons by old habbit.

Current behavior

The Android screenshot preview does not display a thumbnail of the cropped image.
It instead shows the full‑screen capture.

---

Expected behavior

The Android screenshot preview should display a thumbnail of the cropped image based on the configured crop values.

---

Workaround

I guess that the possible workarounds are:

• Implement a Screenshot Tile screenshot preview that overrides Android's screenshot preview. But I have no idea if that is already taking place.
• To crop the image before Android’s screenshot preview occurs — although this may not be technically feasible.

Question

Is Android’s screenshot preview hard‑coded to display the full‑screen capture,
or could it be modified to show the cropped result from the Screenshot Tile when using the Legacy Method?

I am not sure what exactly you mean by "Android’s screenshot preview"

I don't know whether/how this could be influenced.

The Android emulator with a "clean" Android doesn't seem to have this feature, so I would guess that the device manufacturers have to add this preview, which probably means that it can't be changed.

What do you think about the idea to display a notification in the app if "Crop" is enabled, that the "Screenshot preview does not display cropped image"?

Specifically in the "Start recording or casting with Screenshot Tile" pop-up.

Maybe this could be added as an option that can be enabled.
My phone doesn't have this preview either, so I wouldn't want to show a notification as a default behaviour, since it's unclear which phones even show this preview.

(I won't have time for new features for this app for at least 2 months though)

That sounds like a good plan.

I respect your time and fully understand that there’s no urgency in completing this; please don’t feel any pressure.

Just wondering what kind of phone do you have? I tried a few manufactures now, and haven't been able to reproduce this on any phone.

Oops, my apologies — Screenshot Tile does not display screenshot thumbnail previews, I just verified it (Legacy method, tested the Screenshot button from Android's Quick Menu. So I mixed up this issue with the hardware button method of taking screenshots, which uses Android’s built‑in screenshot tool that shows thumbnail previews.

Can you please document something like this in README.md?:

Notice: ScreenshotTile can sometimes be mistaken for Android’s built‑in screenshot tool when it is configured not to use the hardware buttons for taking screenshots.
