Missing dependencies tab in android studio - android-studio

Question

Screenshot http://i.imgur.com/2i41Vih.png
My project is named Pudge. When I open Module settings, I select my project and all the tabs (dependencies, etc.) are missing.
This is probably something stupid, but I don't know what.
Edit: adding more info:
The project has a folder named libraries, and in it there is the folder of the library (facebook in my case)
build.gradle of the main project
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.7.+'
}
}
apply plugin: 'android'
repositories {
mavenCentral()
}
android {
compileSdkVersion 17
buildToolsVersion "17.0.0"
sourceSets {
main {
manifest {
srcFile 'AndroidManifest.xml'
}
java {
srcDir 'src'
}
res {
srcDir 'res'
}
resources {
srcDir 'src'
}
}
test {
java {
srcDir 'tests/src'
}
}
}
defaultConfig {
minSdkVersion 17
targetSdkVersion 17
}
}
dependencies {
compile project(':libraries:facebook')
compile 'com.android.support:appcompat-v7:18.0.0'
compile 'com.google.android.gms:play-services:3.2.25'
}
task wrapper(type: Wrapper) {
gradleVersion = '1.8'
}
build.gradle of the facebook library
apply plugin: 'android-library'
dependencies {
compile 'com.android.support:support-v4:13.0.+'
}
android {
compileSdkVersion 17
buildToolsVersion "17.0.0"
defaultConfig {
minSdkVersion 17
targetSdkVersion 17
}
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java {
srcDir 'src'
}
res {
srcDir 'res'
}
}
}
}
settings.gradle
include ':Pudge'
include ':libraries:facebook'
As I said in the comments - after I added the library through the gradle files - its working. But the tabs are still missing.

Answer 1

Looking at your main build file, it has the comment in it about being the top-level build file, so it looks like your main module is located at the project root instead of inside a folder. This is probably what's confusing the Project Structure dialog, because when it examines settings.gradle, it expects to see modules in the Pudge and libraries/facebook directories.
If my assumption about your main module being at the project root is correct, if you change your settings.gradle file to this it should work:
include ':'
include ':libraries:facebook'
