Now smartphones (the mobile phones in the broad sense, including mobile devices such as mobile phones, tablets, etc.) are becoming more and more important in life, people use mobile phones much more than computers, because of the portability of mobile phones, so many times we will need to use mobile phone to carry data or files, or for entertainment. For example, when riding a train or a car, to see a movie with a mobile phone is quite good, now the p

The Android client is implemented in the following ways:1, first scan all the PC in the LAN to see if there is a PC-side server running and listening to 30000 ports.2. If the server that is not scanned to the PC side is running and listening on port 30000, rescan or exit. 3, scan to the
local and cloud photos. Not only that, you can almost play all the current mainstream audio and video files by installing the free XBMC player on the Android Mini pc.
Application III: Secure and confidential Linux workstation
Most Android Mini PCs support the Linux kernel operating system such as Ubuntu.
The implementation of the androidclient is generally as follows:1, first scan all the PC in the LAN, see if there is a PC server in the execution and monitoring 30000port.Watermark/2/text/ahr0cdovl2jsb2cuy3nkbi5uzxqv/font/5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/dissolve/70/gravity /center ">2, assume that there is no scan to the PC side of the server in the execu

Once the forwarding relationship 1098:1097 is established, the UDP server receives the PC-side message.As shown, the right console sends content to the PC-side socket, and the left logcat is what the socket server in the Android device receives. Of course, in turn, you can send messages directly to the

File transmission through serial ports between the embedded Linux System and the host
I think if I want to download something from my PC to the embedded Linux System of the Development Board, many people will first think of using network tools such as TFTP SFTP to download it from the network port. But if the network is not used, what should I do if I can only download it through the serial port? At this time, there are two tools that can help you:
1, download berserker.android.apps.sshdroid.apk. (If you lazy download, give me a message, I will send you)2, installed to the phone, displaySimple explanation: The General Android system does not have root privileges, Wifi Connection is the name of the network you are connected toAddress is the IP and port number, status run state.3, log is the print log, you click will show all:3.1, when you click on the

These in the professional Android programmer eye may not be a thing, but I still spend a lot of time to check when I do. For example, how to automatically adapt to the screen after hiding, I use a relative layout. This can be seen in the Dark Horse Programmer's Android

WifiManager wifiManager = (WifiManager) getSystemService (WIFI_SERVICE );WifiManager. startScan ();MWifiList = wifiManager. getScanResults ();
WifiManager indicates that it can be used to process the configured network, the current connected network, and the scanning of AP information.

Purpose:Android devices communicate with PCs through wireless networks to facilitate work and learning.
Basic Ideas:In the same LAN, establish a TCP/IP connection between the android configuration and the PC to achieve data exchange
