Couldn't find zipalign. Your APK may not be fully optimized.

$ANDROID_SDK environment variable is set to "/Users//Library/Android/sdk"
where build-tools/22.0.1 and build-tools/23.0.2 are available, both have zipalign file
Also tried to put zipalign to directories with target apks

Add this to your $PATH
export PATH=$PATH:/Users//Library/Android/sdk/build-tools/23.0.2

Sorry, my bad, all works fine, $ANDROID_SDK var were reset to another value.
