Question

我正在尝试将Facebook登录到我的应用程序中。如果我将以下行添加到应用程序的build.gradle文件中：

repositories {
    mavenCentral()
}

in dependencies

compile 'com.facebook.android:facebook-android-sdk:4.2.0'

之后，如果我重建项目，它会成功重建它。但是当我尝试运行时，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:

虽然Message Gradle Build窗口没有显示任何错误。这是它的输出

我还将Gradle VM选项修改为-XX:MaxHeapSize=256m -Xmx256m，但仍然会出错。

如果删除依赖项，它可以正常工作。我不确定为什么会这样。

Answer 1

在我的项目目录中执行此命令./gradlew assembleDebug显示了问题的真正罪魁祸首。

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。由于这个原因，gradle构建失败了。

我在build.gradle文件的构建类型中添加了multiDexEnabled = true。并从MultiDexApplication而不是Application中派生我的自定义应用程序类。

这解决了我的问题。
