Take a look at the docs for startActivityForResult: http://developer.android.com/reference/android/app/Activity.html#startActivityForResult(android.content.Intent, int)
This mentions a specific case with the singleTask launch mode that seems to be exactly what you are experiencing. My guess is that since singleTask and singleInstance are so similar they are behaving the same way. Note the description of launch modes here: http://developer.android.com/guide/topics/manifest/activity-element.html#lmode In general it is not recommended to use singleTask or singleInstance except in very specialized circumstances. Also note that it says singleInstance is the same as singleTask except for an additional constraint. <http://developer.android.com/reference/android/app/Activity.html#startActivityForResult(android.content.Intent, int)> Thanks, Justin Anderson MagouyaWare Developer http://sites.google.com/site/magouyaware On Fri, May 13, 2011 at 9:49 AM, Wall-E <[email protected]> wrote: > Hey Nicholas, > > The launch mode for some of my Activities are "SingleInstance". > > My Activities are my own, custom activities.
