Question

I have used maven-android-plugin 3.0.0-alpha-7 to package the facebook android sdk as a apklib. It looks like this:

    $ unzip sdk-1.0-SNAPSHOT.apklib
    Archive:  sdk-1.0-SNAPSHOT.apklib
   creating: META-INF/
  inflating: META-INF/MANIFEST.MF    
  inflating: AndroidManifest.xml     
   creating: assets/
   creating: res/
   creating: res/drawable/
   creating: res/drawable-hdpi/
   creating: res/drawable-ldpi/
  inflating: res/drawable/facebook_icon.png  
  inflating: res/drawable-hdpi/facebook_icon.png  
  inflating: res/drawable-ldpi/facebook_icon.png  
   creating: src/
   creating: src/com/
   creating: src/com/facebook/
   creating: src/com/facebook/android/
  inflating: src/com/facebook/android/AsyncFacebookRunner.java  
  inflating: src/com/facebook/android/DialogError.java  
  inflating: src/com/facebook/android/Facebook.java  
  inflating: src/com/facebook/android/FacebookError.java  
  inflating: src/com/facebook/android/FbDialog.java  
  inflating: src/com/facebook/android/Util.java  

I then install it into a local repo for my project and include it as a maven dep… and run the build I get this:

$ mvn clean package android:deploy

I see the R files are getting generated and have the correct contents:

$ find target/generated-sources/r/
target/generated-sources/r/
target/generated-sources/r//com
target/generated-sources/r//com/facebook
target/generated-sources/r//com/facebook/Manifest.java
target/generated-sources/r//com/facebook/R.java
target/generated-sources/r//com/company
target/generated-sources/r//com/company/myproject
target/generated-sources/r//com/company/myproject/droid
target/generated-sources/r//com/company/myproject/droid/Manifest.java
target/generated-sources/r//com/company/myproject/droid/R.java

What am I missing to get the R files included in the compilation step?

I already did that for you: https://github.com/casidiablo/android-facebook

Download

Latest version available is 1.5:

• Download JAR
• Download Sources
• Download Javadoc

Maven

You can use it from Maven by including this dependency and repository:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            <version>1.6</version>
            <scope>compile</scope>
        </dependency>
    </dependencies>
