Answer 1

Go the facebook folder which you have imported in your project. Copy the gradle.properties file and paste in into your facebook module.It will remove the errors.

Answer 2

apply plugin: 'com.android.library'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 4
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:22.2.1'
}

EDIT

There is also a GUI way for doing this. It is accessed by selecting the module facebook in the project tree and pressing f4.
Also you can just right-click the facebook and go to Open Module Settings near the bottom.

It is shown in the pictures. The numbers in the picture are top sdk version at the time of writing.

There is a simpler solution. The constants like ANDROID_BUILD_SDK_VERSION can be replaced with normal version "numbers". So instead of

android {
    compileSdkVersion Integer.parseInt(project.ANDROID_BUILD_SDK_VERSION)
    buildToolsVersion project.ANDROID_BUILD_TOOLS_VERSION

    defaultConfig {
         minSdkVersion 8
         targetSdkVersion Integer.parseInt(project.ANDROID_BUILD_TARGET_SDK_VERSION)
    }

..file can look like this:

android {
    compileSdkVersion 19
    buildToolsVersion '19.1.0'

    defaultConfig {
         minSdkVersion 15
         targetSdkVersion 19
    }

Answer 4

First of all, you can add this dependency to your project, without compiling the lib locally.

dependencies {
    compile 'com.astuetz:pagerslidingtabstrip:1.0.1'
}

Otherwise if you would like to compile this lib locally, you have to define these keys in gradle.properties in the root.

ANDROID_BUILD_TARGET_SDK_VERSION=19
ANDROID_BUILD_TOOLS_VERSION=19
ANDROID_BUILD_SDK_VERSION=19

Answer 5

For those who ran into same problems while adding libraries and still can't get it work. The following local include of the .aar file worked for me:

• Just download the .aar file from the maven repo manually.
• In Android Studio go to File -> new Module -> import .JAR or .AAR package and select your downloaded .aar file.

Android Studio does the rest (in the build.gradle) for you. Maybe clean and rebuild your project.
