Question

我正在尝试编写一个Android应用程序，它将使用 neo4j嵌入式 API用于图形数据库。为了开发应用程序，我使用支持Java 8的Android Studio preview version。正在进行构建。但是，当我尝试在目标上运行应用程序时，我在gradle控制台中收到以下错误：

我在互联网上搜索并发现InvokeDynamic not supported错误主要发生在我的应用程序试图使用依赖于lambda的第三方库时。但是，由于我使用的是支持Java 8的Android工作室的预览版，所以lambda不应该有效吗？

Neo4j有没有人遇到过这个问题？关于如何解决这个问题的任何想法？

Answer 1

看起来Android Studio中对Java 8功能的支持尚未完整。

我已经尝试使用Android Studio 2.4 Preview 7，当我使用方法参考功能链接包含此简单类的库时，我的项目编译失败并出现相同的错误：

public class LambdaTest {

    public void test() {
        Runnable runnable = this::run;
        runnable.run();
    }

    public void run() {
    }

}

解决方法是将库的源代码直接放入主Android模块中（如果这些源可用且许可证允许）。或者，等待应解决此问题的Android Studio更新。

使用neo4j构建应用程序作为Android中的库
