How can I use asynctask from android to connect to neo4j server(localhost)

Question

I have neo4j installed on mac with localhost:7474 .How can I add new person name and id via asynctask from android ? Please help me.I am trying from 2 weeks and still no-result.

I had added some code which I tried but I guess embedded db does not work in android: How can I access neo4j running on ( any http or localhost) from android

Also tried:

RestAPI graphDb = new 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();
}

Its still crashing.

Error: java.lang.NoClassDefFoundError: Failed resolution of: Lorg/neo4j/rest/graphdb/RestAPIFacade;

Also: Caused by: java.lang.ClassNotFoundException: Didn't find class "org.neo4j.rest.graphdb.RestAPIFacade" on path: DexPathList[[zip file "/data/app/com.example.1/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]

You will need to add the necessary JAR files to your android project.

But perhaps start with a simple http request first and then try more.
