error: package com.android.annotations does not exist in android studio 2.3.1

Question

I am using

import com.android.annotations.Nullable;

it was compiling and app was running on

Android studio 2.3
gradle version 2.14.1 and
android plugin version 2.2.3.

But after updating to

Android studio 2.3.1
gradle version 3.3 and
android plugin version 2.3.1

it stop compiling. I have searched some other SoF question like this but they are suggesting to use different package

import android.support.annotation.Nullable;

I want to know that is compulsory to use support lib package. If yes the how it was running with other import ?

My application build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.1'
//        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath "io.realm:realm-gradle-plugin:3.0.0"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

}

As you can see in build.gradle I have commented

//apply plugin: 'com.neenbedankt.android-apt'

annotation plugin which I was using in Android studio 2.3 and after updating I have removed it because annotation processor is provided by Android studio itself.

So I want to know why android studio is not able to find

import android.support.annotation.Nullable;

after update is this annotation class is present in plugin which I was using previously ?

@qbait i just change all the import statements. did not able to find the solution yet — prateek, May 10 '17 at 07:14

I'm also got this problem, I had

import com.android.annotations.NonNull;

but wouldn't find the package.

So I commented that line and imported again, it changed to:

import android.support.annotation.NonNull;

wich finally worked.

If that does not affect your project you can use Android Jetpack. For migration

Then simply replace this:

import android.support.annotation.{annotation}

with:

import androidx.annotation.{annotation}
