Android App Manifest merger failed Facebook and Firebase

Question

I'm working on a social app (Facebook and Firebase).

Once I added the firebase gradle path, I got this error:

Error:Execution failed for task ':app:processDebugManifest'.

Manifest merger failed : Attribute activity#com.facebook.FacebookActivity@theme value=(@android:style/Theme.Translucent.NoTitleBar) from AndroidManifest.xml:85:13-72 is also present at [com.firebaseui:firebase-ui-auth:0.6.0] AndroidManifest.xml:69:13-58 value=(@style/FirebaseUI.Translucent). Suggestion: add 'tools:replace="android:theme"' to element at AndroidManifest.xml:81:9-85:75 to override.

build.gradle file:

compile 'com.firebaseui:firebase-ui:0.6.0'
compile 'com.facebook.android:facebook-android-sdk:4.0.0'

Answer 1

The combination of two earlier answers by Nayan Srivastava and MhmdAljobairi worked for me:

<meta-data
                android:name="com.facebook.sdk.ApplicationId"
                tools:replace="android:value"
                android:value="@string/facebook_app_id"
        />

Answer 2

Ever since we added firebase-ui-auth to our project, this error has shown up and if it's not properly fixed, causes facebook activity to crash !

To fix it, update the manifest (notice the new "tools" attribute):

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:tools="http://schemas.android.com/tools"
          package="YOUR_PACKAGE">

    <!-- Facebook API Key -->
    <meta-data
        tools:replace="android:value"
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/facebook_app_id" />

    <activity
        android:name="com.facebook.FacebookActivity"
        android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
        android:label="@string/app_name"
        android:launchMode="singleInstance"
        android:screenOrientation="portrait"/>
