Don't distrust the cursor pos so much as to bug on IPC delay When the cursor is moved by the user, the RichInputConnection is told about it. However, to work around a framework bug, it also looks at how many characters are in the buffer before the cursor, and if that's more than the value it's been passed, it deduces that's a framework bug and there are at least as many characters as seen before the cursor, so it puts the expected cursor position there. When you move the cursor, TextView calls onUpdateSelection, and when you move it fast, you'll get rapid-fire calls to onUpdateSelection. This is fine, the RIC is equipped to deal with that. However, these calls take some time to make it to the IME. In this instance, when the first call gets through and the IME calls TextView (synchronously) for text before the cursor, the cursor has already moved in the app, and TextView returns more characters than the cursor position was declared to be in this instance, so the RIC sets that as the expected cursor position. Sure enough, a split second later, the second call to onUpdateSelection arrives, with the new cursor position set where the RIC had found it too early. The RIC takes that as an "expected" cursor move, and the input does not get reset. Luckily, we have a way out. As far as we know, the framework bug only manifests itself upon rotation, which means we should only have to adjust for it in onStartInputView. Doing it in onUpdateSelection is too zealous (and probably too distrustful of the app to send the correct cursor positions). So we should just take care of the rotation case (by calling tryFixLyingCursorPosition in onStartInputView) and remove the compensating code in resetCachesUponCursorMoves.
