In the past has been in the major sites, the forum to see a variety of technical points and knowledge points, are required to use what technology points, to find relevant posts, never write their own hands;Starting today, I set a goal for myself, will be used in the andorid of technical points and knowledge points are written down, to facilitate their work in the future encounter similar problems, can quickly find a solution------This paste will have a lot of knowledge of the content for the exc

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

Android Broadcast Security0x00 Popular Science Broadcast Recevier is a component that focuses on receiving and processing Broadcast notifications. Many broadcasts originate from system code, such as notifying time zone changes, low battery, taking a picture, or changing language options. Applications can also be broadcast-for example, to notify other applications that some data has been downloaded and is available. An application can have any number of broadcast receivers to respond to all noti

BroadcastReceiver of four Android ComponentsIntroduction to BroadcastReceiver BroadcastReceiver broadcast is a kind of subscription-Notification event. The broadcast receiver sends a broadcast to the Android system register (subscription broadcast), and the Broadcast Sender sends a broadcast to the Adnroid system sendBroadCast (send broadcast ), then, the Android system notifies all the recipients who have registered the broadcast. After receiving the

Definition of BroadcastreceiverBroadcast is a widely used mechanism for transmitting information between applications, which is mainly used to listen to the broadcast information sent by the system or application, then according to the broadcast information as the corresponding logical processing, but also can be used to transmit a small amount of low frequency data.The application is processed by the broadcast of the receiving system when the boot-up service and network status changes, power ch

As in the previous article, only the results are stated here, and the code analysis is given laterIntroduction: This article describes how to first in some pseudo-antivirus software, viruses, general software to obtain text messagesAs we all know, the Android system will send a broadcast when the message is received, but this broadcast is ordered broadcast, that is to say: First received the radio, if the mood is not good, it will not pass this broadcast, the people will not know that there is a

the computer power-on component, this achieves the decoupling effect between the sender and executor. After people know how to send an order, they can perform a lot of operations by clicking the button, such as opening a TV, opening a door, switching the air-conditioning mode, etc, people only need to know that "click the key" to issue a number, and the specific operation is completed by the corresponding command recipient. The following describes in detail what command mode is:The command mode

As in the previous article, only the results are presented here, and code analysis will be provided later. This article describes how to get text messages before some pseudo anti-virus software, viruses, and conventional software. Note: If you want to receive text messages first, please read my previous article and ensure that your application is started first. As we all know, the android system sends a broadcast when it receives a short message, but this broadcast is an ordered broadcast. Tha

the right to allow the sender to send another frame. At the same time, the sender sets a timer for each frame sent. If the timer times out before the arrival of a c k, the sender resends the frame. Note: The sender must store up to w s frames, because re-transmission must be prepared before they are confirmed. The receiver maintains the following three variables: the size of the receiving window (receive window size), which is recorded as rw s, and t

Android: Broadcast and androidbroadcast Concept of Broadcast In reality: we often use radio stations to publish messages by sending broadcasts and buy a radio to listen to them. Android: when the system sends a broadcast when an event is generated, the application uses the broadcast receiver to receive the broadcast and knows what event the system generates. During the running process, the Android system generates many events, such as start

. Command declares the interface for executing the operation. 2. concretecommand binds a receiver object to an action. Call the corresponding operation of the receiver to execute. 3. The client creates a specific command object and sets its receiver. 4. invoker requires this command to execute this request. 5. The aggreger knows how to perform operations related

receiver and the sender, typically to meet the following three points: The sender of the message is able to determine that the message is only intended to be decrypted by the receiving party (there is no guarantee that third parties cannot obtain it, but that third parties cannot decrypt it). The receiver of the message can determine who sent the message (the recipient of the message can deter

. 10. synchronizes the "Hard Disk Data" and "CMOS Parameters" of the sender end to the receiver end through simultaneous network transmission, you can also assign IP addresses, computer names, and group all receivers in the CIDR block according to the data center usage scheme. 11. Install the network control tool master in the basic edition of Lenovo network control tool on the controller computer. So far, the entire data center has been deployed. Ins

OverviewThe Broadcastreceiver will receive the intent sent by Sendbroadcast ().If you do not need to send broadcasts across processes, consider using Localbroadcastmanager, which helps you register and send broadcasts in your own process, which is not cross-process, is more efficient, and does not need to consider the security issues that other applications bring.There are two ways of registering receiver:1. Dynamic registration, through Context.regis

Very convenient.In the Android world, the way is a little different.The start of the service, found on the internet, there are two methods, one is in the use case of the setup to start, a boot on the start of the service. Here we choose the first type, the second one has not been tested, so dare not to be able to be su

The multiple input multiple output (Multiple-input, Multiple-output;mimo) technology provides an excellent way to extend the range of the Wireless area Network (WLAN), and has recently become the focus. MIMO technology began in 1985, but only now applies to wafer-level devices to dramatically improve transmission range and capacity. Since MIMO is not a single concept, but consists of a variety of wireless RF technology, so we must fully understand the operation and performance of MIMO. When app

From the system and macro perspectives, after the application layer is stripped off, the work completed by the GPS receiver can be divided into three parts: signal measurement, data receiving, and geometric calculus. Receiving data refers to receiving data transmitted in the form of bitstream or packets (excluding the data that can be obtained only by measuring the phase, frequency, and intensity of the signal ). Each satellite continuously sends it
