DataBinding worked very well in my project, But after upgrade Android Studio 2.3 today . Run \'app\' failed because following error :
Error:(1
I have also faced the same issue. I was using ButterKnife and Dagger!!
Solved as follow
1) Remove from app level gradle file:
apply plugin: 'android-apt'
or apply plugin: 'com.neenbedankt.android-apt'
2) Remove from project level gradle file:
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
3) And simply change "apt to annotationProcessor" as following dependencies:
apt 'com.jakewharton:butterknife-compiler:8.5.1',
apt "com.google.dagger:dagger-compiler:2.5"
To:
annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1',
annotationProcessor "com.google.dagger:dagger-compiler:2.5"
