I am facing Error while making the project due to Data binding. I fail to understand their logs and the Exception stack trace.
The Entire grade console error says
FAILURE: Build failed with an exception.

Message log says this
Error:cannot generate view binders java.lang.NullPointerException
Error:java.lang.RuntimeException: java.lang.RuntimeException:

Error:java.lang.RuntimeException: failure, see logs for details.
from what I read I have made sure of primitive data type conversions in ternary operator. I still don't know which model/ binding is causing it.
The code has lot of Spinner,Edittext binding with InverBinding Adaptor and BindingAdaptor. I know without code its hard to point out error. But I have my whole project with data binding. I don't know which one to post. Can u shed some light on how would I know where the compilation is failing ?
Thanks
I have just found how to get the error details by switching gradle version. I simply changed grade version from
classpath 'com.android.tools.build:gradle:2.2.0'
to
classpath 'com.android.tools.build:gradle:2.0.0'
This post helped me too InversDataBinding Support
hope this helps someone.
