Android Fragment Tabs being created twice on orientation change -


i'm java vet, new @ android.

anyway, following block of code activity.oncreate() method:

allcontactspage = new allcontactspage(); allgroupspage = new allgroupspage();  viewpager viewpager = (viewpager) findviewbyid(r.id.contactstabsviewpager); contactstabspageradapter tabsadapter = new contactstabspageradapter(getsupportfragmentmanager(), allcontactspage, allgroupspage); viewpager.setadapter(tabsadapter); tablayout tablayout = (tablayout) findviewbyid(r.id.contactsactivitytabs); tablayout.setupwithviewpager(viewpager);  contactsservice.loadallcontacts(this);

the allcontactspage , allgroupspage fragments. add them tablayout using viewpager , fragmentpageadapter (contactstabspageradapter).

after this, call loadallcontacts(this) on service. "this" passed callback, when it's done calls activity, updates both fragments data should display (both fragments instance variables).

my problem that, on rotation, 2 of each fragment created. 1 version displayed in ui, version called callback. 1 displays in ui blank, , never gets data.

i've seen bunch of posts issue, haven't seen how handle fragments managed viewpager/fragmentpageradapter. want know how ensure have correct fragment reference pass data upon rotation.

once resolved, i'm going dive avoiding loading data on rotation, i've figured out how that. need figure out how make display properly.

thanks.

or

<activity      android:name=".youractivity"      android:screenorientation="portrait" />

Today I want to introduce you to two very powerful small business advertising options created by Google. These two ingenious programs have all but revolutionized the way advertising is done on the web. Warning: If you are thinking..."web advertising isn't for me, I just need a few more clients around the block"...you better read this or be prepared to have your competitors eat your lunch.
