FragmentStatePagerAdapter (フラグメントを動的に追加するため) を使用して View-Pager で Fragment(親フラグメント) を使用しようとしています。ビュー ページャー フラグメント (ネストされたフラグメント) で you-tube ビデオをクリックすると、親フラグメントは、対応する you-tube ビデオを再生する別のフラグメントに置き換えられます。

2 つのフラグメント (view-pager を含むフラグメントと you-tube player を含むフラグメント) の間を行き来できます。しかし、前後に移動した後、stackoverflowエラーが原因でアプリがクラッシュします

さまざまなブログを検索してスタック オーバーフローに投稿した後、ネストされたフラグメントがバック スタックからポップされていないことがわかりました。私はすでに次のような解決策を試しました-

public void onBackPressed() {
          if (!fragment.getChildFragmentManager().popBackStackImmediate()) {
                finish();
        }
    }
}

ここで、fragment はビューページャーを含むフラグメントですが、アプリは引き続きクラッシュします。

以下は私のクラッシュレポートと関連コードです
