使用 Android Studio 2.2.2 构建 Google 地图示例项目

Question

我刚刚下载了 Android Studio 2.2.2，并尝试构建示例项目。空白活动项目在我的手机上构建、部署和运行成功。

然后我尝试构建 Google Maps 项目。我获得了一个 API 密钥，将其复制到 google_maps_api.xml 并没有更改任何其他内容。然后，如果我按 Build -> Build APK，它会在 Gradle 控制台中失败并显示以下消息：

首先我注意到“增量 Java 编译是一个孵化功能”消息。也许增量编译是失败的原因？如果是这样，我该如何禁用它？我在 build.gradle 和其他 gradle 相关文件中没有找到任何关于它的信息。

如果增量构建不是原因，那么它是什么以及如何解决它？这个：

Execution failed for task ':app:transformClassesWithDexForDebug'.
    > com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536

看起来像 gradle 内部错误。我对吗？这是我的build.gradle：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Answer 1

com.android.dex.DexIndexOverflowException：方法 ID 不在 [0, 0xffff] 中：65536

您必须为您的项目启用 multidex，因为您的构建中的方法总数超过 65536。请参阅Configure Apps with Over 64K Methods
