INSTALL_FAILED_CONFLICTING_PROVIDER with Facebook SDK when I build multiple productFlavors

Question

I'm building an Android app with multiple productFlavors, and using Facebook SDK v4.1 for login and sharing contents. The problem is that when I try to install an app on a device which already has the same app installed (but different flavor), it raises an error. It doesn't allow me to install the second app unless I uninstall the existing one.

<provider android:authorities="com.facebook.app.FacebookContentProvider{my_app_id}"
        android:name="com.facebook.FacebookContentProvider"
        android:exported="true"/>

According to this document, the android:authorities should be unique and I should have multiple auths to accomplish what I want to do. However, I can't have multiple Facebook AppIds, and was wondering if there's better way to solve this problem. Thanks in advance to anyone who can help me!

Try below :

Manifest

<provider android:authorities="com.facebook.app.FacebookContentProvider${facebookId}"
        android:name="com.facebook.FacebookContentProvider"
        android:exported="true" />
<meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="fb${facebookId}"/>

Gradle

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.1"
    defaultConfig {
        applicationId "com.your.package"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"

        manifestPlaceholders = [facebookId:"123456789"]
    }

    productFlavors {
    debug {
        applicationIdSuffix ".debug"
        manifestPlaceholders = [facebookId:"1234"]
    }
    release {
        applicationIdSuffix ".pro"
        manifestPlaceholders = [facebookId:"123456789"]
    }
}
