这是我的模块build.gradle：

apply plugin: 'com.android.application'

android {
compileSdkVersion 19
buildToolsVersion '20.0.0'
defaultConfig {
    applicationId 'iyh.queensbase.my.inyourhand'
    minSdkVersion 14
    targetSdkVersion 20
    versionCode 1
    versionName '1.0'
}
buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
productFlavors {

}
dependencies {
      compile fileTree(include: ['*.jar'], dir: 'libs')
      compile project(':facebook')
