Default Activity not found adding firebase - firebase

Question

I have an instant app, and its working nice, but if I add this line to my base/build.gradle then I cant run my app/installed, note that I can run it with a url.
api 'com.google.firebase:firebase-core:16.0.1'
The error is "Default activity not found".
Removing the compile firebase, voilá the activity is found.
Using implementation instead of api the app runs nice, but firebase says "installation unsucessful" but using api and running it as a instant app firebase says "successful"
My build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion rootProject.ext.compileSdkVersion
defaultConfig {
applicationId "com.example.android.app"
minSdkVersion rootProject.ext.minSdkVersion
targetSdkVersion rootProject.ext.targetSdkVersion
versionCode rootProject.ext.versionCodeInstalled
versionName rootProject.ext.versionNameInstalled
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation project(':feature')
implementation project(':base')
}
Manifest app:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.app" />
Manifest base:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android">
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<meta-data
android:name="aia-compat-api-min-version"
android:value="1" />
</application>
</manifest>
Any idea?

This solution worked for me:
In the base/manifest
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<meta-data
android:name="aia-compat-api-min-version"
android:value="1" />
<provider
android:name="com.google.firebase.provider.FirebaseInitProvider"
android:authorities="com.menuymenu.android.app.firebaseinitprovider"
android:exported="false"
tools:node="merge"/>
</application>
