I'm releasing 3rd party keyboard application on the Google Play Store.
I received some ANRs like below
Input dispatching timed out (e716b5 InputMethod (server) is not responding. Waited 10001ms for MotionEvent)

fun onKeyChar(ic: InputConnection) {
this.ic = ic
if (!enabled)
return
val inputText = ic.getTextBeforeCursor(16, 0) ?: return
service.themeManager.animateFromText(inputText.toString())
}
}
When a user send key up event, my keyboard app send a character to EditText and get the text before cursor for word suggestion. And I don't know why this function takes too long time and how to prevent this situation...
