Setup Devices for Development

Getting Started with Android
With Android devices you can set up the phone for development using USB or Wifi. To use wifi connection Android has a tool called adb (Android Device Bridge) part of Android Platform-Tools which has to be installed on your computer first. The phone also needs to be first connected for development via USB. You can then tell the adb to listen to port 5555 using your command prompt (console window)

adb tcpip 5555

and then connect to mobile phone by using your mobile phone's IP address e.g.:-

adb connect 192.168.1.110:5555

This web page shows you how to connect directly to your mobile phone if you would like to use your mobile phone in place of the mobile emulator which can be very slow if you do not have an Intel based pc.

You can connect your phone by using a USB cable or by using your wifi network if the phone and the pc are connected to the same wifi network.

You may need to download and install platform tools which include the ADP (Android ) if you get a "adp is not recognised..." message
