Facebook Unity SDK Android integration - Cannot merge android manifests

Unity Engine
1

Hi,

I spent a lot of time searching for answers but cannot find any solution.
I am trying to integrate Facebook SDK to 7.10.0 in Unity 5.6.1f1.

I have setup Facebook Settings correctly. Every Facebook feature works fine in the editor. (Previously I used 7.9.0 / Unity 5.4.1 and everything worked fine on android). I can compile when removing Facebook generated manifest, but Facebook features don’t work.

Here is my Plugins/Android/AndroidManifest.xml file :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.unity3d.player" android:installLocation="preferExternal" android:theme="@android:style/Theme.NoTitleBar" android:versionCode="1" android:versionName="1.0">
  <supports-screens android:smallScreens="true" android:normalScreens="true" android:largeScreens="true" android:xlargeScreens="true" android:anyDensity="true" />
  <application android:icon="@drawable/app_icon" android:label="@string/app_name" android:debuggable="true">
    <activity android:name="com.unity3d.player.UnityPlayerNativeActivity" android:launchMode="singleTask" android:label="@string/app_name" android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
      <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="false" />
    </activity>
    <activity android:name="com.facebook.unity.FBUnityLoginActivity" android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen" android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen" />
    <activity android:name="com.facebook.LoginActivity" android:screenOrientation="portrait" android:configChanges="keyboardHidden|orientation" android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen">
    </activity>
    <activity android:name="com.facebook.unity.FBUnityDeepLinkingActivity" android:exported="true" />
    <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="fb596157827168029" />
    <activity android:name="com.facebook.unity.FBUnityDialogsActivity" android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen" android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen" />
    <activity android:name="com.facebook.unity.FBUnityAppLinkActivity" android:exported="true" />
    <activity android:name="com.facebook.unity.FBUnityGameRequestActivity" />
    <activity android:name="com.facebook.unity.FBUnityCreateGameGroupActivity" />
    <activity android:name="com.facebook.unity.FBUnityJoinGameGroupActivity" />
    <activity android:name="com.facebook.unity.AppInviteDialogActivity" />
    <provider android:name="com.facebook.FacebookContentProvider" android:authorities="com.facebook.app.FacebookContentProvider596157827168029" android:exported="true" />
  </application>
</manifest>

When trying to build for Android, I get the following error :
“Unable to merge android manifests”

“Error: Error while saving blame file, build will continue
Error: Le prefixe “tools” de l’attribut “tools:overrideLibrary” associe a un type d’element “uses-sdk” n’est pas lie.”

One other fact is, in Facebook Unity SDK getting started for Android (Android - Unity SDK - Documentation - Meta for Developers), I see I should set Min API level to level 15 but I cannot see it in Player settings (but I installed it in Android Manager) as Unity 5.6.x targets Min API >15. I tried specifying a uses-sdk min sdk version of 16 in the manifest.

Please help me I am stuck on this issue for days,

Thanks in advance,
Michael
