Error while generating APK - android-studio

Question

I'm trying to generate an APK from Android Studio for publish it on the play store.
Now when i generate the APK i got this error:
I can start the app but "Generate APK" not work and for avoid this error i copy my Facebook App Id from my string.xml to my manifest:
android:value="2132153153153535"
Instead of:
android:value="#string/facebook_app_id"
Now i can generate the APK but when i launch my app from the playstore i got this error:
Unable to start activity ComponentInfo{com.stable.giamma.sushichallenge/com.stable.giamma.sushichallenge.MenuActivity}: java.lang.IllegalArgumentException: Both context and applicationId must be non-null
That i can resolve by reversing the modify that i just did.
But if i do so i can't generate the APK again.....
What is the right way for handle the "facebook app id" and generate the APK?
p.s: i have 2 string.xml (one is for english and the other for italian language) dunno if create some problem...
Here is my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.asd.appname">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
o
<application
android:allowBackup="true"
android:icon="#mipmap/asd"
android:label="#string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="#string/facebook_app_id" /> //THIS IS THE STRING THAT I MODIFY FOR AVOID THE FIRST ERROR
<activity
android:name="com.asd.MainActivity"
android:label="#string/app_name"
android:screenOrientation="landscape"
android:theme="#style/AppTheme.NoActionBar" />
<activity
android:name="com.facebook.FacebookActivity"
android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="#string/app_name"
android:theme="#android:style/Theme.Translucent.NoTitleBar" />

</activity>
<activity

</application>

Answer 1

I added:
tools:ignore="ManifestResource"
The correct code is:
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="#string/facebook_app_id"
tools:ignore="ManifestResource"/>
