I'm thinking of implementing a new feature for Thumb-Key: richer haptic feedback that will make it easier for users to blind-type.

While reviewing the current places where Thumb-Key already performs haptic feedback, I noticed something strange.

When doing a long-press gesture, there are two moments of haptic feedback. First is when the finger initially touches the keyboard key, and second when enough time has passed for the press gestured to be registered as a long press. The second haptic feedback is noticeably stronger than the first.

However, as far as I can tell, both events call the exact same function with the same parameter for both events:

view.performHapticFeedback(HapticFeedbackConstants.KEYBOARD_TAP)

So how come the second feedback is stronger than the first?

Here is the code for initial press.

And here is the code for the long press.

There was a discussion about this article 2 years ago here and here, but I thought it's such an interesting a novel concept full of potential that it's worth a repost.

Hi, I'm looking for a place to download Pokémon HeartGold & SoulSilver for Nintendo DS. Any recommendations? Thanks

I'm using Android Studio on Windows 11, and trying to debug ThumbKey on an emulated device.

For some reason, the ThumbKey keyboard doesn't appear.

Looking at the logs in Logcat, there is one suspicious line:

2025-07-24 19:50:30.200  4769-4769  ImeBackDispatcher       com.dessalines.thumbkey.debug        E  Ime callback not found. Ignoring unregisterReceivedCallback. callbackId: 88733492

I'm new to Android dev, so I'm not sure how to debug this.

I tried fiddling with the keyboard settings of the emulated device, and some other proposed solutions I found on StackOverflow, but nothing I tried worked so far.

I am testing this on version 5.0.3 (commit acad975f51d7b399a567b2d1217a3209b6bbef96)

Is there an Android app that detects nearby WiFi and connects to networks whose password is known from a publicly registry of WiFi password?

I'm new to Android dev, and I recently added my first contribution to ThumbKey (the Key Modifications feature).

I noticed that ThumbKey saves user settings using a Room database rather than using DataStore, or its outdated equivalent SharedPreferences.

Why is that? What's the advantage?
