I have a cordova project. I want to add Facebook Login Plugin to my project. I cloned the plugin to my project as cordova plugin add https://github.com/Wizcorp/phonegap-facebook-plugin/ --save --variable APP_ID="myAPP_ID" --variable APP_NAME="myApp" . Later I added hash to Facebook App. My first question How many hash I have to use? I just add one hash to Facebook App. When I added plugin to my app I build project I get error. How can I correct this problem?
Where: Build file 'C:\login\platforms\android\phonegap-facebook-plugin\login-FacebookLi b\build.gradle' line: 15
What went wrong: A problem occurred evaluating project ':phonegap-facebook-plugin:FacebookLib'.
Could not get unknown property 'ANDROID_BUILD_SDK_VERSION' for project ':phone gap-facebook-plugin:FacebookLib' of type org.gradle.api.Project.
