OnClick with rx.Action0 not working

[MishkaOwner]

Currently using the latest configuration.
compileSdkVersion 24
buildToolsVersion "24.0.2"
and with gradle com.android.tools.build:gradle:2.2.0

public final Action0 onClickRx = new Action0() {
@OverRide
public void call() {
System.out.println("Hello world");
}
};

this just simply prints

Error:Execution failed for task ':app:compileDebugJavaWithJavac'.
java.lang.RuntimeException: Found data binding errors.
***/ data binding error ***msg:Cannot find the setter for attribute 'android:onClick' with parameter type rx.functions.Action0 on android.widget.Button.

Ah I realized Using bindAdapter fixes this. sorry for inconvenience
