Incompatible plugins for android-apt after upgrading to Android Studio 2.3

After upgrading from 2.2 to 2.3 I see this warning

enter image description here

and when I try to compile the project I see this compilation error

enter image description here

How can i solve this issue without downgrading to a previous gradle version? Is there any update of android-apt that can solve this issue?

Solution

  • The android-apt plugin has been deprecated.
    Check here for the migration guide:

    As of the Android Gradle plugin version 2.2, all functionality that was previously provided by android-apt is now available in the Android plugin.

    You can remove android-apt by following the migration guide to get the equivalent functionalities.

    The important parts from the migration guide:

    • Make sure you are on the Android Gradle 2.2 plugin or newer.
    • Remove the android-apt plugin from your build scripts
    • Change all apt, androidTestApt and testApt dependencies to their new format:
    dependencies {
   compile 'com.google.dagger:dagger:2.0'
   annotationProcessor 'com.google.dagger:dagger-compiler:2.0'
}

    Also in the Android Gradle plugin there is an explicit check for this, which is what you are seeing:

    using incompatible plugins for the annotation processing android-apt

    Future Android Gradle plugin versions will not be compatible with the way android-apt works, which is the reason for that check.
