type KeyCharacterMap ¶

type KeyCharacterMap struct {
	DeviceId int32
}

KeyCharacterMap is a native C++ parcelable whose wire format is defined by JNI (android_view_KeyCharacterMap.cpp) and libinput (KeyCharacterMap.cpp).

JNI envelope (nativeWriteToParcel):

int32  deviceId
bool   hasMap (int32: 0 or 1)

If hasMap, KeyCharacterMap::writeToParcel follows:

CString  loadFileName  (null-terminated, no length prefix)
int32    type
bool     layoutOverlayApplied
int32    numKeys
per key:
  int32  keyCode
  int32  label
  int32  number
  repeated {int32(1), metaState, character, fallbackKeyCode, replacementKeyCode}
  int32(0)  sentinel
int32 numKeyRemapping,  pairs of (from, to) int32
int32 numKeysByScanCode, pairs of (scanCode, keyCode) int32
int32 numKeysByUsageCode, pairs of (usageCode, keyCode) int32
