尝试创建一个简单的应用程序，从语音API接收文本并将其发送到java服务器。从跟踪调试。代码不会超出我打开插座的TRY块。

代码更新：现在应用程序没有崩溃。但没有消息流。

因为在写这个答案的时候，作者还没有添加一个堆栈跟踪，我将讨论一些基本的解决方案：

确保您已为Android清单添加了INTERNET权限，否则您的套接字将无法打开<uses-permission android:name="android.permission.INTERNET" />
在后台线程上打开您的套接字。在Android
如果以上方法无法解决您的问题，请添加堆栈跟踪

将字符串发送到Java Application时Android应用程序中的问题
