In my Android Studio androidManifest.xml file, I found an unresolved package generated. How can I fix it?

The issued code is : android:name=".provider.generated.SquawkProvider

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.aaa">

<uses-permission android:name="android.permission.INTERNET" />

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

<activity
    android:name=".MainActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

<provider
    android:name=".provider.generated.SquawkProvider"
     <!--  shows unresolved package "generated" -->

    android:authorities="com.example.android.aaa.provider.provider"
    android:exported="false" >
</provider>

<activity
    android:name=".following.FollowingPreferenceActivity"
    android:parentActivityName=".MainActivity">
    <meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value=".MainActivity" />
</activity>

<service
    android:name=".fcm.MyFirebaseMessagingService">

        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>

</application>
</manifest>

This issue stems from annotation processing now being included in Gradle from version 2.2. You can fix project and get it running with the following changes.

Project level "build.gradle" remove this line:

classpath 'com.neenbedankt.gradle.plugins:android-apt:1.2'

App level "build.gradle" remove this line:

apply plugin: 'android-apt'

and change this line replacing apt with annotationProcessor:

apt 'net.simonvt.schematic:schematic-compiler:0.6.3'
