Gluon Mobile：低功耗蓝牙没有接口实例 com.gluonhq.attach.ble.BleService

Question

我是 Whosebug 的新手，这是我的第一个 post。我最近开始使用 Gluon Mobile 开发一个使用低功耗蓝牙的 android 移动应用程序。

我在使用 BLE 技术时遇到问题。如果我复制 gluon mobile documentation 中提供的一段代码，我会收到以下消息：

WARNING: No new instance for interface com.gluonhq.attach.ble.BleService and class com.gluonhq.attach.ble.impl.AndroidBleService

示例代码如下：

        ble.startScanningDevices().addListener((ListChangeListener.Change<? extends BleDevice> c) -> {
            while (c.next()) {
                if (c.wasAdded()) {
                    for (BleDevice device : c.getAddedSubList()) {
                        System.out.println("Device found: " + device.getName());
                        device.stateProperty().addListener((obs, ov, nv) -> {
                            if (State.STATE_CONNECTED == nv) {
                                System.out.println("Device connected: " + device.getName());
                            }
                        });
                        ble.connect(device);
                    }
                }
            }
        });
    });

我还修改了 AndroidManifest.xml 文件，通过向文件添加以下行来提供使用蓝牙的必要权限：

<uses-permission android:name="android.permission.BLUETOOTH"/>

<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

大家遇到过这种问题并且解决了吗？感觉连不上蓝牙了

Answer 1

解决方案是将 <list>ble</list> 添加到 pom.xml 文件中的 <attachList>。
