I had the same trouble and "fixed it" by a workaround: I check the
fragments are loaded and only store those on the Bundle. From time to
time it fires an Exception but it works anyway.
@Override
protected void onSaveInstanceState(Bundle instanceStateToSave) {
super.onSaveInstanceState(instanceStateToSave);
FragmentManager manager = getSupportFragmentManager();
int fragmentsCount = mPagerAdapter.getCount();
// page on display
int visiblePage = mViewPager.getCurrentItem();
instanceStateToSave.putInt("visiblePage", visiblePage);
try {
manager.putFragment(instanceStateToSave,
PageFragment.class.getName() + visiblePage, (PageFragment)
mPagerAdapter.getItem(visiblePage));
} catch (Exception e) {
// TODO something
}
// preloaded pages
int offScreenLimit =
getResources().getInteger(R.integer.offScreenLimit); // this is a
setting I use with setOffscreenPageLimit(), usually its value is 2
int minPage = ((visiblePage - offScreenLimit)>0)?(visiblePage -
offScreenLimit):0;
for(int i = minPage; i < visiblePage; i++) {
try {
manager.putFragment(instanceStateToSave,
PageFragment.class.getName() + i, (PageFragment)
mPagerAdapter.getItem(i));
} catch (Exception e) {
// TODO something }
}
int maxPage = ((visiblePage + offScreenLimit +
1)>fragmentsCount)?fragmentsCount:(visiblePage + offScreenLimit + 1);
for(int i = visiblePage + 1; i < maxPage; i++) {
try {
manager.putFragment(instanceStateToSave,
PageFragment.class.getName() + i, (PageFragment)
mPagerAdapter.getItem(i));
} catch (Exception e) {
// TODO something }
}
}
