This can be configured in C + + WEBRTC turn. The Web/android/ios is similar.If you consider it from a security aspect. You can generate a key for your account so that you can log in directly via key. Without having to provide a password.Key is generated via turnadmin, required (username, password, realm). Realm is specified by the-r parameter when you start turn server.For example, this:

Replaces the character in the character sequence N of the current StringBuffer object with the character specified by the parameter ch, and the value of n must be non-negative and less than the length of the string sequence in the current object.
Reverse ()
Use the reverse () method to flip a sequence of characters in an object.
Delete (int n, int m)
Deletes a sequence of substrings from a sequence of characters in the current StringBuffer object. H
create a message Queue for the main thread. In this strand thread does not establish a message Queue. Therefore, the Mylooper value is null, and mainlooper points to the looper of the mainline thread. Then, execute to:Mhandler = new MyHandler (mainlooper);This mhandler belongs to the main thread.Mhandler.sendmessage (m);The M message is deposited into the message queue of the main thread. Mainlooper sees a message in the message queue and processes it, and the main thread executes to Mhandler's

The role of this process is to synchronize buffer cache information with the information on the database disk.The process is specifically done with the following 4 things:A) log buffers are written to the log fileb) checkpoint record written to log filec) Swipe data cache to diskd)

WCF learning journey-Example 3 () and Example 3I. Preface
Based on the previous 20 chapters, we know what it is: WCF; A, B, and C in WCF; the transfer mode of WCF; the boarding mode of WCF; and Exception Handling of WCF. This article combines the above knowledge points and writes a small WCF application-BookMgr ).

Find the key point function or judgment faster, then go back to the Smali level and modify the code. This approach is more accessible, and the final step is to go back to the Smali level to modify the code.

set of messages that identify a particular component. Such a special set of messages usually expresses some additional information. The information for the component should be described in detail, as some component information will be sent to other components as messages. For example, the ' Qtdemux ' QuickTime rectifier (demuxer) should store the ' redirect ' information in the component information in order to send the ' redirect ' component informa
