У меня есть ListView, и когда строка нажата, я хочу начать новое действие. Просмотр списка отображается на вкладке «Фрагмент». Код, я использую для отображения активности является:Сбой приложения для Android на startActivity
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
Intent intent = new Intent(mView.getContext(), SessionActivity.class);
startActivity(intent);
}
Когда я запускаю код отображается новая активность, но приложение сразу же падает. Это то, что я получаю в журнале:
