Viewpager Loose Fragment Connection On Low Memory Kill

in my activity i use viewpager. I create two fragments and attach the to the view pager and time to time calling some methods from this fragments in my activity.. afer the app is k

Solution 1:

I found the solution....

it is really like a said that my fragment variables in the main activity is cleared so i have no connection to the fragments anymore.. what i did is inside the onAttach() i linked my fragment to the mainActivity variables again

@Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        mActivity = activity;
        ((RestaurantActivityViewPager)mActivity).menuFragment=this;
    }
    public static MenuFragment newInstance(int sectionNumber) {
        MenuFragment fragment = new MenuFragment();
        Bundle args = new Bundle();
        args.putInt(ARG_SECTION_NUMBER, sectionNumber);
        fragment.setArguments(args);
        return fragment;
    }

Solution 2:

If you get tabFragment by this code

Fragment fragment = mPagerAdapter.getItem(position);

It caused that bug when low memory. Try with this one

fragment = getSupportFragmentManager().findFragmentByTag("android:switcher:" + R.id.rewards_viewpager + ":"+position);
