I already have my android sdk installed and I also have java installed.

this is what is in my .bach_profile

export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools
export JAVA_HOME=$Home/Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home

I've tried adding a local.properties file and added sdk.dir pointing to my Android/sdk folder. But still this error persists. How do I fix this?

So the solution to my problem was:

1) add my ANDROID_HOME and JAVA_HOME paths in my .bash_profile

Solution by @rana_sadam

2) Create local.properties and add sdk.dir=<PATH TO ANDROID SDK> inside the android folder.
