intent to be parsed, and the intent filter without the specified category can only match the intention of no category. It is important to note that Android treats all the implicit intentions passed to startactivity () as if they contain at least one category: "Android.intent.category.DEFAULT" (Category_default constant).Each part of the intended data URI is compared with the data label of the intent filter, and the intent filter without the specified data value will match all intent data values
) explicitly specifying the intent of the component name as an explicit intent, specifies that the intent should be passed to that component. By following the code, you can create a materialized object and set the parameter information that needs to be passed. Because the specific component object is explicitly specified, it is not necessary to set other intent filtering objects for intent. [Java] //1. Creating Intent instantiation objects intent Intent = new Intent (); intent.setclass (Cont

Golang API
Golang NET package has a very convenient API for us to use, this API can be divided into Addr,listen,connection,dialer,ip and other network APIs, such as DNS API, etc. There are no other Web APIs (mainly self-study _).
Addr mainly have ipaddr,tcpaddr,udpaddr and unixaddr, the main is different address, this is the basis of network programming, no address i
HTTP request, the code above looks very simple and intuitive. But underneath it hides a lot of low-level details, including client timeouts, server timeouts, and load-balancing timeouts. # # The HTTP request timeout for the client timeout client has several forms, depending on the location of the timeout frame throughout the request process. The entire request response process is composed of ' Dialer ', ' TLS handshake ', ' request header ', ' reques
, generally, the vroeigrp that runs the OSPF Protocol needs to configure Dialer list and Dialer group on the dial-up backup port to filter unnecessary packets or run the TRIP protocol. This increases the overhead of the vro operation. OSPF supports on-demand dial-up on the dial-up network. Only one routing protocol can meet the needs of various leased lines or dial-up network applications.3. the loop-free c

PPPoE has always been a key point in vro settings. Today, we will analyze and introduce the PPPoE setting process on the 2600 router. First, we will take a look at the configured network environment based on the network topology, and then parse the specific code.

This relationship also needs to send the HELLO Message periodically even on the dial-up network, in this way, on the on-demand dial-up network, it is impossible to locate whether this is a useful service message or a scheduled inquiry message sent by the kernel, which may trigger a connection on the On-Demand dial-up network by mistak
