I am new in developing native app using Salesforce SDK. I tried to create android project from command line using forcedroid tool but there is problem in setting environment
Open the terminal and type :
export ANDROID_HOME=/Applications/ADT/sdk
Add this to the PATH environment variable
export PATH=$PATH:$ANDROID_HOME/platform-tools
If the terminal doesn't locate the added path(s) from the .bash_profile, please run this command
source ~/.bash_profile
Hope it works to you!
