Question

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

    dependencies {
compile project(':library')

compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'
compile files('libs/httpmime-4.2.5.jar')
compile files('libs/gcm.jar')

compile project(':com_facebook_android')
compile 'com.android.support:support-v4:22.2.1'
compile 'com.google.android.gms:play-services:6.5.87'
}
