GET THE CURRENT GPS LOCATION AND SHOW IT IN THE GOOGLE MAPS IN ANDROID WITH SOURCE CODE

GET THE CURRENT GPS LOCATION AND SHOW IT IN THE GOOGLE  MAPS IN ANDROID WITH SOURCE CODE

      In this example the users current position is taken by using the Gps or   here the Gps value is set in the emulator .in emulator take DDMS and select the emulator control and set the latitude and the longitude value.before run your application send this value to emulator.the sample program is given below,
