Android obtains the mobile phone information (device IP, OS version etc .) I haven't written anything for a long time. Today I am making a PV log record. I need to record the OS version, WiFi IP address, current time, and so on. I have investigated and shared the following: Package com. Osip; Import java. Text. dateformat;Import java.

To do this, port mapping is also done first.Map the native port tcp/6100 to the emulator (5554) tcp/7100 port (UDP is the same).>adb–s emulator-5554 forward tcp:6100 tcp:7100After the port mapping is successful, proceed to the following experiment.Method 1 (correct):Simulator (5554)-server:serversocke

I, broadcast recipientBroadcast recipient Broadcastreceiver, how to understand the broadcast receiver?System, there are many special events, such as SD card mount, outgoing calls, receive SMS and other events. We just have to register a broadcast receiver, the equivalent of buying a radio, we can receive these special events.These events, when they happen, always send out broadcasts.II, implementing IP dialing1)Effect: Enter a number to be stored as a

This article describes the Android implementation approach to acquiring wired and wireless IP addresses. Share to everyone for your reference. Specifically as follows: To do the development of Android, encountered the problem of getting a wired IP address. Not much to say code! for (enumeration Analysis:

Operation Steps: To increase the WiFi safety factor, you can turn off DHCP without wiring, so that when you connect to WiFi, you need to set up a static IP.Here's how to set up static IP under Android 4.0. Note: 1, open wifi; 2, click on the need to connect the WiFi access point name; 3, enter the password, the input method hidden will find "Display password" and "Show advanced options", or long by sig
