The logs for the second build (`LeanType log 2.txt`) show that the application is operating, but it continues to experience stability and configuration issues, many of which are consistent with the previous build.

### Key Observations from `LeanType log 2.txt`:

* 
**Vibrator HAL Issue:** The log shows an repeated error: `E VibratorInfo: Invalid frequency profile received from HAL`. This confirms that the keyboard is still unable to correctly interface with the device's vibration hardware, which is a system-level issue and likely outside your direct control in the keyboard code.


* 
**Activity Lifecycle:** The logs extensively show `SettingsActivity` being created, resumed, paused, and stopped. This suggests the settings screen is functional but might be cycling frequently, possibly due to configuration changes or how the UI is being handled.


* 
**Input Handling:** There are several logs related to `InputLogic` attempting to jump to placeholders and managing gesture inputs, although some actions are being reported as canceled.


* 
**Permissions/Denials:** You are seeing `avc: denied { read }` errors for properties like `qemu_sf_lcd_density_prop`. These indicate SELinux permission denials, which are common when testing on emulators or restricted environments, and might be blocking the keyboard from accessing certain device properties.



### Comparison to Previous Build (`LeanType log 1.txt`):

The missing `libjni_latinimegoogle.so` library error noted in the first build is not explicitly highlighted in the snippet of the second build, but the core issue regarding the integration of the Kotlin-based gesture engine versus the system's expected JNI libraries remains the likely bottleneck.

### Recommendations for Next Steps:

1. 
**Address the Manifest:** Please ensure you have added `android:enableOnBackInvokedCallback="true"` to your `AndroidManifest.xml` as identified in the first build, as this is a required modern Android configuration.


2. **Focus on Gesture Engine Logic:** The `InputLogic` warnings suggest the core gesture engine is interacting with the `SettingsActivity`. Since you are modifying `SwipeGestureEngineKotlin.kt`, focus on ensuring that the `SettingsActivity` is not triggering a reset of the engine every time the activity pauses or restarts.
3. 
**Review the "Dictionary Not Synchronizing" log:** Your log contains explicit debug messages stating: *"The dictionary was not synchronizing with the user personal dictionary"*. This is a clear indicator of where the logic is failing. Since you mentioned wanting to re-integrate features developed in Java, **please share the relevant code block responsible for dictionary synchronization** (likely inside or called by `SwipeGestureEngineKotlin.kt` or your dictionary helper classes). I can then review it to ensure it correctly interfaces with the user's personal dictionary.



When you are ready, please upload the files containing the dictionary synchronization logic so we can resolve that specific issue.

Crash

This is not a Kotlin bug – it’s a native memory corruption bug inside the C++ LatinIME dictionary code.
Specifically, the crash happens while buildIndex is iterating over the dictionary (forEachWord).

Why this matters for “OK”:
If the dictionary traversal triggers a double‑free, the index building might abort, partially fail, or corrupt the gesture index before it finishes. This would cause some words (especially those later in the dictionary order) to simply be missing from the index, which is exactly what you’re seeing with “OK”.

What you (or the LeanType developer) should do:

This is a critical JNI / C++ issue in the underlying dictionary reader. It needs to be reported to the LeanType developer with the exact backtrace you provided.

The immediate workaround is to see if the crash happens every time buildIndex runs. If the index is being rebuilt frequently (e.g., after a settings change), that would explain why the engine sometimes works partially.
