Android Studio 2.3 update : Warning:Using incompatible plugins for the annotation processing: android-apt. This may result in an unexpected behavior

Question

So, I have read all the questions I could find on this site regarding this issue. I have also had a chat in comments with one of the developer with similar issue, who was able to solve it.

I dont have apt or annotationProcessor written any where in my gradle scripts.

I dont have the word android-apt written anywhere in my code. I even went ahead and checked out all the libraries. That were included in my project.

This is a really big problem and needs to be solved.

I am attaching the modified build.gradle below, Please suggest :

    apply plugin: 'com.android.application'
apply plugin: 'realm-android'


android {
    dexOptions {
        jumboMode = true
    }

    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion


    useLibrary 'org.apache.http.legacy'
    defaultConfig {
        applicationId "com.legalimpurity.indiancourts"
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode rootProject.ext.versionCode
        versionName rootProject.ext.versionName

        multiDexEnabled true
        vectorDrawables.useSupportLibrary = true;
    }
    buildTypes {
        release {
//            minifyEnabled true
//            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    signingConfigs {
    }

    dataBinding {
        enabled = true
    }

Answer 1

Older versions of Realm use android-apt. You should upgrade your realm-android plugin version.

Mace

Wooh Amazing ! Thanks ! I checked all my dependencies, not classpath libraries ! – Casebook

@botteap I got this warning with realm-android plugin to 2.1.1, so I upgraded it to 2.2.0, but then I got Error:Gradle DSL method not found: 'apt()' Do you know any way to fix this ? – Silent

My guess is that you are still using the old Realm plugin for some reason. I don't use Realm myself so I can't tell for sure. – Mace

Answer 2

Replace

classpath "io.realm:realm-gradle-plugin:1.2.0"

with

classpath "io.realm:realm-gradle-plugin:3.1.2"

and then apply plugin

apply plugin: 'realm-android'
