Ran into this issue tonight on my Droid (2.2). I think there's an issue in FragmentActivity.startActivityFromFragment(...).
YMMV, but this seems to fix it for me: https://github.com/petedoyle/android-support-v4-googlemaps/commit/06307de35a9de0a89ff52bb42a358ba6740e542c Basically there are two issues: 1) "(fragment.mIndex+1)<<16" should be in parentheses since + has precedence over << in Java 2) requestCode*0xffff should be requestCode&0xffff. (I think the goal is to strip all but the first 16 bits of the request code). To understand the fix, assume you have a fragment index of 0 and a requestCode of 1. With the current code: (fragment.mIndex+1)<<16 + (requestCode*0xffff) = (0+1)<<16 + (1*0xFFFF) = (1)<< (16 + 0xFFFF) // since + has precedence over << = 1<<65551 = 32768 // according to my debugger = 1000 0000 0000 0000 // fragment index is lost, request code changes from 1 to 32768 With this change: ((fragment.mIndex+1)<<16) + (requestCode&0xffff) = ((0+1)<<16) + (1&0xFFFF) = (1<<16) + 1 = 65536 + 1 = 65537 = 1 0000 0000 0000 0001 Thanks, Pete On Wed, Mar 9, 2011 at 9:20 AM, Dianne Hackborn <hack...@android.com> wrote: > Does the API demo for this work wherever you are running it?
