如何在Android应用中准确定时发送数据？

public void sendData(String data) {
    // 在这里编写发送数据的逻辑
}

String dataToSend = "Hello, World!";
sendData(dataToSend);

public void sendData(String data) {
    OkHttpClient client = new OkHttpClient();
    
    RequestBody requestBody = new FormBody.Builder()
            .add("data", data)
            .build();
    
    Request request = new Request.Builder()
            .url("http://example.com/api")
            .post(requestBody)
            .build();
    
    try {
        Response response = client.newCall(request).execute();
        // 处理服务器返回的响应
    } catch (IOException e) {
        e.printStackTrace();
    }
}
