My purpose is this: while clicking on the "ISD" edit box in activity 1, a second activity containing a list of countries will be displayed from which the user will select a country and after that the first activity will get the country code. In activity second, I have used async calls to list of countries from the RESETful webservice. But here the problem is after finishing the Activity2, Activity 1 never displayed to show the ISD code ( that means, StartActivityForResult seems to be not working properly as intended.. While debugging its found that, OnCreate method of Activity2 is called again after finishing it.. 1 Day passed, but I didnt get a solution.. Please help
