Unknown Application ABI

[getfile]

hi:

i use eclipse4.7.1a with cdt9.3.2

Application.mk
APP_OPTIM := debug
APP_ABI := arm64-v8a
APP_STL := c++_shared
APP_PLATFORM := android-24

ndk is android-ndk-r16b
os is win10 64bit

in cmd mode, ndk-gdb work fine.

but when debug project in cdt , i got
"
[2018-05-19 18:07:25 - testNDK] Unknown Application ABI:
[2018-05-19 18:07:25 - testNDK]
[2018-05-19 18:07:25 - testNDK] Unable to detect application ABI's
"

how can i fix it? thanks
