我正在尝试将我的 android 应用程序与本地主机上的 couchbase 服务器连接我已经初始化数据库和管理器如下：初始化数据库后，我正在调用 startSync() 函数接受数据库类型的参数

                  public static final String DB_NAME = "firstdb";
                    public static final String TAG = "firstdb";private void helloCBL() {
                        Manager manager = null;
                        Database database = null;
                        try {
                            manager = new Manager(new AndroidContext(this), Manager.DEFAULT_OPTIONS);
                            database = manager.getDatabase(DB_NAME);
                            database.addChangeListener(this);
                            startSync(database);

                        } catch (Exception e) {
                            Log.e(TAG, "Error getting database", e);
                            return;
                        }

                    }

这是 startSync() 函数

         protected void startSync(Database database) {
                        URL syncUrl;
                    try {
                        syncUrl = new URL("http://10.0.2.2:4984/firstdb");
                    } catch (MalformedURLException e) {
                        throw new RuntimeException(e);
                    }


                    Replication pullReplication = database.createPullReplication(syncUrl);
                    pullReplication.setContinuous(true);

                    Replication pushReplication = database.createPushReplication(syncUrl);
                    pushReplication.setContinuous(true);

                    pullReplication.addChangeListener(this);
                    pushReplication.addChangeListener(this);


                    // start both replications
                    pullReplication.start();
                    pushReplication.start();

                }

但是我的 logcat 出现错误如下：我对在 android 应用程序中使用 url 感到困惑

当我在 android 设备上运行应用程序时会发生这些错误。当我在模拟器上运行我的应用程序时，它没有显示任何错误，但会给出详细的消息

通过与朋友讨论，我得到了上述问题的解决方案，我刚刚将笔记本电脑和 Android 手机连接到同一个网络（从 localhost 访问服务器时很重要），然后我在 startSync() 函数中更改了 url，如下所示：

http://192.168.1.17:4984/firstdb

192.168.1.17

这是我的笔记本电脑的 IP 地址，4984是监听 sync_gateway 请求的端口只需对上述代码进行这些简单的更改，您就可以在 android 应用程序中使用 sync_gateway
