Android NDK location not valid in preferences on MAC

Android NDK location not valid in preferences on MAC

I already google it, and up to now the solutions that I got didn't help me :/
this is my .profile:
export
ANDROID_NDK="/Users/eduardoreis/Documents/workspace-support/android-ndk-r9"
export
ANDROID_NDK_ROOT="/Users/eduardoreis/Documents/workspace-support/android-ndk-r9"
export NDK="/Users/eduardoreis/Documents/workspace-support/android-ndk-r9"
export PATH="$PATH:$ANDROID_NDK"
And when I click in the option add Native Support it says: - NDK location
not valid in preferences
And also, this Eclipse for some reason doesn't have Android>NDK>NDK_PTH
(like on Windows OS) [I already saw this, Android-NDK-Add Native
Support-NDK location not valid in preferences, but it is not my case] :/
I don't know what to do. It has one week that I've trying different things...
Are my environment variables messed up or wrong?
