Java – This FragmentManager should be recycled after using #recylce().

Here is my code :

protected void showNewsItem(News news) {
    FragmentManager fm = getFragmentManager();
    FragmentTransaction ft = fm.beginTransaction();
    DialogFragment newFragment = MyNewsFragment.newInstance();
    newFragment.show(ft, "dialog");
}

This FragmentManager should be recycled after use with #recylce() error appears on the beginTransaction line.

I’ve tried adding fm.recycle(); Just like the error message, but this gives me the error that recycle is undefined.

Use the DialogFragment.show (FragmentManager manager, String tag) version instead.
So in your case:

protected void showNewsItem(News news) {
    DialogFragment newFragment = MyNewsFragment.newInstance();
    newFragment.show(getFragmentManager(), "dialog");
}

Usually, the above idiomatic usage is enough to display DialogFragment.

The show (FragmentTransaction transaction, String tag) version is used to “carry” existing FragmentTransaction.
