I am developing an android application in which i am using fragments. And in that I am change language from English to Arabic after click on list item and its work fine.
But What i want that the language which is selected is remain in whole application even after we force close application from device.... But it doesn't happen with me....
If i am using with Activity then i have call
setContentView(R.layout.main);
in onResume() Method and its work fine.
But my question is that how can we set a view with fragment or call onCreateView method on onResume() method because onCreateView() method returns itself view.. So have tried a lot to solve it but i couldn't.. So please is there any way to solve it??
Thanks in Advance.
This is my Code:
