Сбой приложения Android после входа в систему и на экране logcat отображается ошибка?

Question

Я делаю приложение, как Uber, и я должен поместить местоположение драйвера с маркером на приложение и после входа в систему показывает загрузку, а затем вылетает? я импортировал все библиотеки правильно, но мой экран logcat Я пытался перейти к аналогичным вопросам на stackOverflow, но ничего не работает, и эта ошибка просто показывает снова и снова, и я не могу запустить свое приложение. Приветственная деятельность
