推荐答案

Gear2 通知框架不是作为 Android Wear 框架内置的.为此，您必须实现两个方面，您的 Gear2 应用程序和您的 Android 主机应用程序.

Gear2 notification framework isn't built in as Android wear framework. To do it, you must implement two sides, your Gear2 app and your Android host app.

在您的 Gear2 应用程序上，棘手的部分是接受来自主机应用程序的连接的 javascript 回调.

On your Gear2 app, the tricky part is the javascript callback to accept connection from host-app.

    var agentCallback = {
    onrequest : function(peerAgent) {
        //accept connection if there is a request from host app
        SAAgent.acceptServiceConnectionRequest(peerAgent);
    },
    onconnect : function(socket) {
        console.log("agentCallback onconnect" + socket);

                SASocket = socket;
        SASocket.setDataReceiveListener(onreceive);
        SASocket.setSocketStatusListener(function(reason) {
            console.log("Service connection lost, Reason : [" + reason + "]");
            disconnect();
        });
                //do whatever logic you want like setting up GUI, changing text
    },
    onerror : onerror
};

在 Android 主机应用程序上，您必须通过调用 findPeerAgents 启动连接，并在有响应时请求连接:

On Android host app, you must initiate the connection by calling findPeerAgents and when there is a response, request the connection:

@Override
protected void onFindPeerAgentResponse(SAPeerAgent arg0, int arg1) {
    Log.d(TAG, "onFindPeerAgentResponse  arg0 =" + arg0);
    try{
        requestServiceConnection(arg0);
    }catch (Exception e){
        e.printStackTrace();
    }
}
