如何从Android使用asynctask连接到Neo4j服务器（本地主机）

我在localhost：7474的Mac上安装了neo4j。如何通过android中的asynctask添加新的人名和ID？请帮助我。我从2周开始尝试，仍然没有结果。

我添加了一些尝试的代码，但是我猜嵌入式数据库在android中不起作用：如何从android访问在任何http或localhost上运行的neo4j

还尝试了：

RestAPI graphDb =新的RestAPIFacade（“ http：// localhost：7474 / db / data ”）;

QueryEngine engine=new RestCypherQueryEngine(graphDb);
QueryResult<Map<String,Object>> result = engine.query("create (:Person {name:\"Steve\"}) return n", Collections.EMPTY_MAP);
Iterator<Map<String, Object>> iterator=result.iterator();

if(iterator.hasNext()) {
    Map<String,Object> row= iterator.next();

    int duration = Toast.LENGTH_LONG;
    Toast toast = Toast.makeText(getApplicationContext(),"" + row.get("total") , duration);
    toast.setGravity(Gravity.CENTER, 0, 0);
    toast.show();
}

它仍然崩溃。

错误：java.lang.NoClassDefFoundError：无法解决以下问题：Lorg / neo4j / rest / graphdb / RestAPIFacade;

另外：原因：java.lang.ClassNotFoundException：在路径：DexPathList [[zip文件“ /data/app/com.example.1/base.apk”中找不到类“ org.neo4j.rest.graphdb.RestAPIFacade” “]，nativeLibraryDirectories = [/ vendor / lib，/ system / lib]]
