[Android SDK Home] No Android SDKs were found under the specified SDK location In Mac

Hello, I am having a problem with Titanium Studio and android sdk configuration.

Here is my specifications

Mac OS 10.9.4 java version "1.7.0_67" titanium SDK 3.3.0.GA Titanium Studio, build: 3.4.0.201409032048 Titanium CLI 3.3.0 Latest android version 4.4.2 is installed. My android sdk is in "/Users/MAC/Documents/android-sdk-macosx"

The problem i am having is In my studio "Dashboard/Configure Native SDKs" the andoid sdk is showing configured. But in "Preferences/studio/platform/android/" though my android sdk path is given, there is a error showing " [Android SDK Home] No Android SDKs were found under the specified SDK location"

i have try to follow the guides and everything. no result. one solution i tried was deleting "/Users/MAC/Library/Application Support/Titanium/mobilesdk/osx/3.3.0.GA/node_modules/titanium-sdk/lib/emulators/genymotion.js" file. but it made worse i guess.

also i tried to follow these links
