Surfaceview is used to dynamically display the current video of the camera. in step 3, you need to enable the camera and configure it, And then enable preview.
[Java] MSurfaceHolder = mSurfaceView. getHolder ();MSurfaceHolder. addCallback (SimplePaintActivity. this );MSurfaceHolder. setType (SurfaceHolder.

I. I will provide a detailed description of these content in several subsequent articles. Before that, we must first understand how to understand the database execution plan. This article only describes the execution plan of a single table operation. DM database, oracle database, and sqlserver database can all display the execution plan of a given statement. I have analyzed these three numbers in detail.

For work requirements, read some flashcache content and record it as follows:
Implementation
Flashcache is a new open-source project developed by the Facebook Technical Team. It uses SSD hard disks to cache data to accelerate a MySQL kernel module. We can see that it was initially used for database acceleration, but it was also designed as a general cache module for any application built on Block devices.
Working principle. Based on device Mapper, it maps a fast SSD hard disk and a common ha

multicast group members in the network, IP multicast routing protocols can be divided into the following two basic types. First, assume that multicast group members are densely distributed in the network. That is to say, most subnets in the network contain at least one multicast group member, and the network bandwidth is large enough, this multicast routing protocol, called dense-mode, relies on broadcast technology to push data to all routers in the network. The IP Multicast Routing Protocol i
