Can't run with Facebook SDK included

Question

I am stuck when trying to run my app with the FacebookSDK for Android included into my project in IntelliJ IDEA.

With a basic Android boilerplate, everything builds and runs fine. But as soon as I try to add the Facebook SDK to my project as explained in this post, I get multiple errors:

java: /Users/me/Projects/Android/facebook/src/com/facebook/widget/LoginButton.java:25: package android.support.v4.app does not exist

java: /Users/me/Projects/Android/facebook/src/com/facebook/widget/LoginButton.java:33:
cannot find symbol
symbol  : class R
location: package com.facebook.android

Detailed screenshots:

Why is that and how can I solve it?

Answer 1

The problem with your project is that the Facebook SDK module has the altered AndroidManifest.xml file that specifies the wrong package causing R.java file to be produced in a different package, hence the non-working imports.

Original AndroidManifest.xml file can be found here:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.facebook.android">
    <application/>
    <uses-sdk android:minSdkVersion="8" />
</manifest>

Answer 2

Android support v4 is the android support library. It backports some classes to older versions of the SDK. You can find the jar in your SDK, under extras. You need to include it in your project.
