See.. I have page which show article. On menu click a function it sets new content as below
setContentView(R.layout.sharing); Now this layout has edittext and button. On click on button ..It goes as given in that tutorial.. But when use authenticates.. Then in onResume I get error because I think he cant find that edittext. But as our activity is resuming, then that our last layout was R.layout.sharing It should open na ? And as i said that layout has edittext where has typed something. .. One more input .. I added log in my onCreate and onResume So when user comes back from broswser. onCreate is also getting called. and after that onresume is getting called. Just because oncreate is getting called. our last layout is not there. It just shows articles list. On Nov 24, 2:46 pm, Kumar Bibek <[email protected]> wrote: > Umm, > > I am still confused.
