Android ArrayList <String []>到PHP

Question

I need my app to send an ArrayList<String[]> to php, I have this to call the service:

ArrayList<String[]> Items = new ArrayList<String[]>();
(...)
JSONObject JSONSend= new JSONObject();
JSONSend.put("Items", Items );

HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000);
HttpResponse response;
HttpPost post = new HttpPost(SERVICE);
post.setHeader("json", JSONSend.toString());
StringEntity se = new StringEntity(JSONSend.toString());
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json"));
post.setEntity(se);
response = client.execute(post);

and on the PHP service:

$data = file_get_contents('php://input');
$json = json_decode($data);
$Items = $json->{'Items'};
error_log($Items);

and the php is returning this:

[[Ljava.lang.String;@413e2fd0, [Ljava.lang.String;@413a2940, [Ljava.lang.String;@4139df18, [Ljava.lang.String;@4141b5b0, [Ljava.lang.String;@413931c8, [Ljava.lang.String;@41348b40, [Ljava.lang.String;@41393928]

The type of the $ServMade is string, so how can I take care of the data as an array on php? Am I missing something?

Try the following when generating json string in android:

JSONObject JSONSend= new JSONObject();
JSONArray ja = null;
JSONArray tmp = new JSONArray();
for(String s[] : Items){
    ja = new JSONArray();
    for(int i = 0; i<s.length; i++)
        ja.put(s[i]);
    tmp.put(ja);
}
JSONSend.put("Items", tmp);
