method is to determine whether the network connection code, return True indicates that there is a network, return false indicates no network. In the development of Android Web applications, it is often necessary to determine whether a network connection is available, so it is often important to listen for changes in

this class, we make the throwable of the same type: 1. If we are exception, we will judge again, according to different kinds of exception, converted to responethrowable return, and give different code and message; 2. If runtimeexception, we convert to responethrowable return; in summary, we take the exception that we get, The HandleException () method is transformed into a unified responethrowable return, which contains the code and message. 2. Then create a new subscriber base class

The ADSL Broadband Access Network is still quite common, So I studied how to check the connection status of the ADSL Broadband Access Network. Here I will share it with you, hoping it will be useful to you. Now, there are more and more friends who use ADSL, LAN, and other broadband methods for high-speed Internet access, such as the LAN-based ADSL Broadband Acces
