Вот полный код моего приложения. Во-вторых, если я делаю MainActivity в качестве действия Launcher. то MainActivity работает очень хорошо, иначе, когда я делаю SplashActivity в качестве активности запуска, он дает ошибку, которую вы можете увидеть в logcat.

Answer 1

Изменение theme в манифесте (<application> тег) от:

android:theme="@style/AppTheme" 

к:

android:theme="@style/AppTheme.NoActionBar" 

или добавить theme атрибут MainActivity «s <activity> тега.

До этого изменения система ожидает, что вы хотите ActionBar в MainActivity.
