MIUI/HyperOS: Attempt to invoke virtual method crash #1278
Description
(Last updated March 15, 2025)
-
This issue request is for Xiaomi users, where it causes Mihon to crash with the following crash line:
NullPointerException: Attempt to invoke virtual method 'float android.window.BackMotionEvent.getTouchX()'. -
The reason & workaround below is still relevant, and is not an app-related issue as others have reported such crashes in other apps outside of Mihon.
-
This crash happens when you use your device's navigation buttons and/or gestures after updating the device's HyperOS Launcher to a certain version.
-
The current workaround to this issue is to downgrade your HyperOS Launcher to a certain version and/or to the Global version. See the comments below this issue description for more details.
This section is for documentation purposes, see comments below instead.
