Create an Java array of arrays as Codeigniter insert_batch method requires

I'm developing an Android app that communicates with an Rest API (Codeigniter). I'm trying to query into my SQLite database and create an array on format that Codeigniter requires. The insert_batch method requires something like this:

Here is my code so far:

Cursor c = db.query(MY_QUERY);
c.moveToFirst();
while(c.isAfterLast()==false)
{
   // TODO: here I have to insert the keys->values into an array of arrays
}

// Here I have to return this array;
return dataArray;

My Codeigniter's Rest API code (Controller):

public function myController_post()
{
    $dados = $this->post('dataArray');


    if($this->myModel->insertMyData($dataArray)) {
        return true;
    }
    return false;
}

And my model:

function insertMyData($data) {
    return $this->db->insert_batch('my_table', $data); 
}

The question is: how to create this array of arrays from my cursor?
