When it comes to data encryption, these words are often involved:Algorithm, Original, secret, and key. Generally, the sender uses an encryption algorithm to encrypt the original text and then sends it to the receiver. Then, the receiver decrypts the ciphertext with the key to obtain the original text. Since common encryption algorithms are public, the key to the original text encryption is the key. Encrypti

When it comes to data encryption, these words are often involved: algorithms, original texts, passwords, and keys. Generally, the sender uses an encryption algorithm to encrypt the original text and then sends it to the receiver. Then, the receiver decrypts the ciphertext with the key to obtain the original text. Since common encryption algorithms are public, the key to the original text encryption is the k

I. Overview of the Android broadcast mechanismAndroid broadcasts are divided into two areas: the broadcast sender and the broadcast receiver, usually broadcastreceiver refers to the broadcast recipient. Broadcast as a means of communication between Android components, you can use the following scenarios:1. Message communication within the same component inside the same app (between single or multiple threads);2. Message communication between different

parameters," Nobody Knows Why, it just works ... The final algorithm is used in today's TCP protocol (Linux source code: tcp_rtt_estimator). TCP sliding window To illustrate, if you don't understand the TCP sliding window, you're not aware of the TCP protocol. We all know that TCP must solve the problem of reliable transmission and packet chaos, so TCP must know the actual network data processing bandwidth or data processing speed, so that will not cause network congestion, resulting in packet

Contains information about remote objects used and exposed by applications. Contains information about the lifetime of active objects for all clients that provide services for this application.

, broadcast, when a new peering discovery or when the device's Wi-Fi status changes, for example. You can register a broadcast receiver that processes these intents to receive these intents in the application:Table 3. P2P intent of wireless network connectionDescriptionWIFI_P2P_CONNECTION_CHANGED_ACTION broadcast when the device's wi-fi connection status changes.WIFI_P2P_PEERS_CHANGED_ACTION broadcast when you call discoverPeers (). Usually you want t

The broadcast receiver is used to receive and process broadcast notifications (broadcastannouncements ). Most broadcasts are initiated by the system, such as region change, insufficient power, and incoming calls. The program can have any number of broadcast receivers to respond to the notifications it deems important. Broadcast receiver can notify users in multiple ways: Start activity, use icationicationma

What is Broadcastreceiver? as one of the four components of Android, Broadcastreceiver also plays an important role in the development of the Android program, broadcasting is very similar to the radio in our real life. The radio station sends its content on a channel, so that anyone who listens to the channel will receive it. In Android, the broadcast is also divided into two roles: broadcast sender , broadcast receiver . Broadcastreceiver's applicati

Requestpeers () to get a list of the most recent peer-network (devices). Wifi_p2p_state_changed_action This broadcast is sent when the device's Wi-Fi peer is enabled or disabled. This broadcast is sent when the device's Wi-Fi peer is enabled or disabled. Wifi_p2p_this_device_changed_action This broadcast is sent when the details of the device are modified, such as the name of the device. 2. Create a broadcast

is the binary form of the data, the connection layer is the signal form of the data. It would be interesting to see the world in a different way, and it would be more like a whole to look at the four layers.When the data is sent through these four layers, the data is used as the body after each layer, and the control information of this layer is added as the header. When the destination is reached, this passes through layer four, each layer will be stripped of the corresponding header, and fina

Basic Principles of connectable objects and connection points In order to provide greater interaction between the component object and the customer, the component object also needs to actively communicate with the customer. The Component Object communicates with the customer through the outgoing interface. If a component object defines one or more output interfaces, this component object is called a connectable object. The so-called outbound interface is also a COM interface. Each outbound Inte

The command mode is also a common mode in development. It is not too difficult and relatively simple. Let's write the command mode in detail below. Advantages 1. Reduce the Coupling Degree of the system. 2. New commands can be easily added to the system. 3. You can easily design a combined command.Disadvantages Using the command mode may cause some systems to have too many specific command classes. Because a specific command class needs to be designed for each command, some systems may need a la
