在neo4j作爲庫建設應用程序在Android中的

Question

我想寫一個Android應用程序將使用neo4j嵌入式圖形數據庫的API。爲了開發應用程序，我使用的是支持Java 8的Android Studio preview version。大樓正在正常運行。然而，當我試圖運行在目標上的應用程序，我收到以下錯誤在gradle這個控制檯：

我搜索在互聯網，來到知道InvokeDynamic not supported錯誤主要是發生在我的應用程序試圖使用依賴lambda的第三方庫。然而，因爲我使用的是Android Studio的預覽版，它支持Java 8，所以lambda不應該工作？

有沒有人用Neo4j遇到過這個問題？有關如何解決該問題的任何想法？

Answer 1

看起來Android Studio對庫中Java 8功能的支持並不完整。

我已經與Android 2.4工作室7預覽實驗，編制爲我的項目失敗，同樣的錯誤，當我鏈接包含使用方法參考功能這個簡單的類庫：

public class LambdaTest { 

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

    public void run() { 
    } 

} 

一種解決方法是把你的庫的源直接放到主要的Android模塊中（如果這些源可用並且許可證允許的話）。或者，等待Android Studio更新應解決此問題。
