using facebook sdk in Android studio

Question

I'm following Facebook SDK for Android using Android Studio. When I run my application I'm getting the below mentioned warning.

Gradle: module 'facebook' won't be compiled. Unfortunately you can't have non-Gradle Java module and Android-Gradle module in one project. 

How should I solve this?

I tried @Scott Barta's answer and get the following error message.

    A problem occurred configuring project ':App'. > Failed to notify project evaluation listener.    > A problem occurred configuring project ':libraries:facebook'.       > Failed to notify project evaluation listener.          > Could not resolve all dependencies for configuration ':libraries:facebook:_DebugCompile'.             > Could not find any version that matches com.android.support:support-v4:+.

Answer 1

NOTE

For Android Studio 0.5.5 and later, and with later versions of the Facebook SDK, this process is much simpler than what is documented below (which was written for earlier versions of both). If you're running the latest, all you need to do is this:

1. Download the Facebook SDK from https://developers.facebook.com/docs/android/
2. Unzip the archive
3. In Android Studio 0.5.5 or later, choose "Import Module" from the File menu.
4. In the wizard, set the source path of the module to import as the "facebook" directory inside the unpacked archive. (Note: If you choose the entire parent folder, it will bring in not only the library itself, but also all of the sample apps, each as a separate module. This may work but probably isn't what you want).
5. Open project structure by Ctrl + Shift + Alt + S and then select dependencies tab. Click on + button and select Module Dependency. In the new window pop up select :facebook.
6. You should be good to go.

Instructions for older Android Studio and older Facebook SDK

This applies to Android Studio 0.5.4 and earlier, and makes the most sense for versions of the Facebook SDK before Facebook offered Gradle build files for the distribution. I don't know in which version of the SDK they made that change.

Facebook's instructions under "Import the SDK into an Android Studio Project" on their https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android-using-android-studio/3.0/ page are wrong for Gradle-based projects (i.e. your project was built using Android Studio's New Project wizard and/or has a build.gradle file for your application module). Follow these instructions instead:

1. Create a libraries folder underneath your project's main directory. For example, if your project is HelloWorldProject, you would create a HelloWorldProject/libraries folder.

2. Now copy the entire facebook directory from the SDK installation into the libraries folder you just created.

3. Delete the libs folder in the facebook directory. If you like, delete the project.properties, build.xml, .classpath, and .project. files as well. You don't need them.

4. Create a build.gradle file in the facebook directory with the following contents:

   buildscript {     repositories {         mavenCentral()     }     dependencies {         classpath 'com.android.tools.build:gradle:0.6.+'     } }  apply plugin: 'android-library'  dependencies {     compile 'com.android.support:support-v4:+' }  android {     compileSdkVersion 17     buildToolsVersion "19.0.0"      defaultConfig {         minSdkVersion 7         targetSdkVersion 16     }      sourceSets {         main {             manifest.srcFile 'AndroidManifest.xml'             java.srcDirs = ['src']             resources.srcDirs = ['src']             res.srcDirs = ['res']         }     } } 

   Note that depending on when you're following these instructions compared to when this is written, you may need to adjust the classpath 'com.android.tools.build:gradle:0.6.+' line to reference a newer version of the Gradle plugin. Soon we will require version 0.7 or later. Try it out, and if you get an error that a newer version of the Gradle plugin is required, that's the line you have to edit.

5. Make sure the Android Support Library in your SDK manager is installed.

6. Edit your settings.gradle file in your application’s main directory and add this line:

   include ':libraries:facebook' 

7. If your project is already open in Android Studio, click the "Sync Project with Gradle Files" button in the toolbar. Once it's done, the facebook module should appear.

8. Open the Project Structure dialog. Choose Modules from the left-hand list, click on your application’s module, click on the Dependencies tab, and click on the + button to add a new dependency.
9. Choose “Module dependency”. It will bring up a dialog with a list of modules to choose from; select “:libraries:facebook”.
10. Click OK on all the dialogs. Android Studio will automatically resynchronize your project (making it unnecessary to click that "Sync Project with Gradle Files" button again) and pick up the new dependency. You should be good to go.
