Hi

howdy, Gabriele!

how can I help you today?

My terrible connection :(

Do you still have the github project?

yes

I think i'm doing something bad with fragments because when i receive the intent from the browser i get null exception from isconnected method inside wikifragment class

"when i receive the intent from the browser"?

do you mean a separate Web browser app?

Yes the default one

oh, via the *.wikipedia.org <intent-filter>

OK

Maybe my instantiation is bad or something like this hm and when changhing fragment i have getactivity null

Yes

presumably, you are getting the NullPointerException on the first line of isConnected()

and that because getActivity() is null

if so, that means you are calling loadUrl() too early

I ran into that with EU4You

which is why my DetailsActivity caches the URL and hands it over to the fragment in onPause(), IIRC

This is what i thought so i moved it after onactivitycreated

getActivity() should return non-null in onActivityCreated()

Is it wrong? Im getting null

which activity or activities can host WikiFragment?

I have only wikiapp

hold on, let me look at it

well, you call onCreatedView() from the fragment in onCreateView()

onCreatedView() calls goTo()

goTo() calls loadUrl()

Yes that before my last update when i moved it to oncreatedactivity

I could not update it becuase of my dead connection TT

I don't know what to tell you

put a breakpoint on the line that crashes and confirm that the call tree is what you think it is

Under mypageradapter

The fragment instantiation is correct?

it's not obviously wrong

Do i need the two get methods? Or i should use getactivity always?

what "two get methods"?

Getwikifragment and getbookmarkfragment

there is nothing wrong with what you have that I see

I' using them to access fragments from the mainactivity

again, there is nothing obviously wrong with your approach

Can happen that i'm referring to the bad one in this case? Like old fragment ect.

Hm

only if you are only encountering this problem on a configuration change or something

wait

what is the *precise* set of steps that is causing your crash?

I open the browser, open a wiki page, choose my app and then it crashes

does it happen when you start from the home screen launcher?

Yes

OK, so it always happens?

Yes

then it cannot be tied to a configuration change, as you are not always doing a configuration change

Ah

and, that's the end of today's chat

I will investigate better if my connecion comes back, for the next time

the next one is tomorrow at 10am Eastern

Thank you very much

have a pleasant day!

See you, good bye
