IllegalStateException: is not currently in the FragmentManager

Question

I know it sounds like a duplicate of FragmentStatePagerAdapter IllegalStateException: is not currently in the FragmentManager but his solution isn\'t relevan

Answer 1

The FragmentStatePagerAdapter is a horrible piece of code riddled with bugs acknowledge or not by Google and so I use this code to fix this particular crash:

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        // Yet another bug in FragmentStatePagerAdapter that destroyItem is called on fragment that hasnt been added. Need to catch
        try {
            super.destroyItem(container, position, object);
        } catch (IllegalStateException ex) {
            ex.printStackTrace();
        }
    }

Answer 2

Use the following

final FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.add(f, key);

instead of

mFragmentManager.putFragment(state, key, f);

and pass the bundle explicitly..

For reference,

Answer 3

You could try using mFragmentManager.add();

Answer 4

Write in Activity onCreate() method :

pager = (ViewPager) findViewById(R.id.pager);
    adapter = new SwipePagerAdapter(getSupportFragmentManager());
    pageOneFragment = new PageOneFragment();
    adapter.addFragment(pageOneFragment);

Adapter code:

public class SwipePagerAdapter extends FragmentStatePagerAdapter
{
private final ArrayList<Fragment> mFragments = new ArrayList<Fragment>();

public SwipePagerAdapter(FragmentManager fm)
{
    super(fm);
}

@Override
public Fragment getItem(int position)
{
    return mFragments.get(position);
}

@Override
public int getCount()
{
    return mFragments.size();
}

public void addFragment(Fragment fragment)
{
    mFragments.add(fragment);
    notifyDataSetChanged();
}

@Override
public void destroyItem(ViewGroup container, int position, Object object)
{
    super.destroyItem(container, position, object);
}

@Override
public CharSequence getPageTitle(int position)
{
    return super.getPageTitle(position);
}}

Answer 5

Double-check whether you've implemented onSaveInstanceState and onRestoreInstanceState in your activity, and verify that they're correctly saving and loading the state of your fragments.

Answer 6

Try using

use fragmentTransaction.add()
