TL;DR: you have to write your application’s ID in your
strings.xml
and then reference (i.e.@strings/fb_app_id
), because if you put it directly (as value) intoAndroidManifest.xml
it won’t work.
you must define your applicationId
in the AndroidManifest.xml
like this:
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>
under <application android:label="@string/app_name"....
tag
where app_id
is a string within your strings.xml
.
sample:
<application android:label="@string/app_name"
android:icon="@drawable/icon"
android:theme="@android:style/Theme.NoTitleBar"
>
<activity android:name=".HelloFacebookSampleActivity"
android:label="@string/app_name"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity android:name="com.facebook.LoginActivity"
android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:label="@string/app_name" />
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>
</application>
** please note <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>
is within <application>
tag
— and in strings.xml
<string name="app_id">1389xxxxxxxx</string>
