Java Android上的MongoDB连接超时

我用JavaSwing和MongoDB制作了一个小应用程序

我正在尝试为Android开发相同的应用程序，当我尝试连接时，与MongoDB数据库的连接会超时

我用我的三星（Samsung）3G接入设备和安卓（android）虚拟设备（可以接入互联网）试用了这个应用程序

我使用一个MongoLab数据库，代码与我的JavaSwing应用程序相同，驱动程序也相同

//DB
MongoClientURI uri  = new MongoClientURI("mongodb://user:password@ds033750.mongolab.com:33750/db"); 
MongoClient mongo = null;
try {
    mongo = new MongoClient(uri);
} 
catch (Throwable e) {
    e.printStackTrace();
}
DB db = mongo.getDB(uri.getDatabase());
DBCollection imagesCollection = db.getCollection("images");
DBCursor cursor = imagesCollection.find();
try {
    while(cursor.hasNext()) {
       DBObject obj = cursor.next();
       Log.d("test", (String) obj.get("name"));
    }
} finally {
    cursor.close();
}

以下是错误：
