将 Android Studio v0.8.14 与 Facebook SDK v3.22.0 结合使用。
在 Android Studio 中，添加 facebook-sdk/facebook 文件夹作为模块。并且模块已作为依赖项添加到项目结构设置中。 Gradle 同步没问题。尽管当我尝试运行应用程序时遇到那些奇怪的错误:

这也是应用程序的 build.gradle:

}

}
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
}
}
apt {
arguments {
androidManifestFile variant.outputs[0].processResources.manifestFile
resourcePackageName 'com.general.application'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:support-v4:19.0.0'
compile 'com.android.support:appcompat-v7:19.0.0'
compile 'com.parse.bolts:bolts-android:1.1.4'
compile fileTree(dir: 'libs', include: 'Parse-*.jar')
apt "org.androidannotations:androidannotations:$AAVersion"
compile project(':facebook')
}
我已经检查了所有使用旧版本 Android Studio(例如 v0.5.x)的文档，甚至是 YouTube 教程。 Facebook 文档已被弃用，并且示例不适合 Android Studio，因此我找不到正确的配置。
任何帮助都会很棒。
最佳答案
所以我自己找到了答案。
我的 Android Studio 已过时，因此请按照建议进行更新。然后清除了所有 Facebook SDK 内容，包括 gradle 文件并重新添加。仅此而已。
