我正在尝试将Facebook登录集成到我的应用程序中。如果我在应用程序的build.gradle文件中添加了以下几行:
repositories {
mavenCentral()
}
在依赖中
compile 'com.facebook.android:facebook-android-sdk:4.2.0'
之后，如果我重建项目，它将成功重建它。但是，当我尝试运行时，它需要很长时间才能构建，然后显示带有文本的对话框:
Failed to complete Gradle execution.
Casue:
尽管Message Gradle Build窗口没有显示任何错误。这是它的输出

我也将Gradle VM选项修改为
-XX:MaxHeapSize=256m -Xmx256m，但仍然给出错误。如果我删除依赖关系，它会正常工作。我不确定为什么会这样。
最佳答案
在我的项目目录中执行此命令./gradlew assembleDebug显示了问题的真正原因。
当我将facebook SDK依赖项添加到我的项目时，它超出了我的dex文件中64K方法的限制。因此，gradle构建失败。
我将multiDexEnabled = true添加到build.gradle文件的构建类型中。然后从MultiDexApplication而不是Application派生我的自定义应用程序类。
这解决了我的问题。
