Xamarin Forms Android-приложение вылетает после всплеска (запуск)

Я разрабатываю приложение (IOS and Android), используя Xamarin Forms.
Я пытаюсь запустить приложение Android, но, к сожалению, приложение сбрасывается после заставки.
Я пробовал с Emulator, а также physical device(Moto G3).
Я обновил Xamarin studio с последним выпуском stable. Я попытался сменить рабочий solution directory, но тот же вопрос сохраняется.
Я сохранил точку останова в SplashActivity OnCreate(), но отладчик не пришел к этой строке.

Не могли бы вы отправить информацию об исключении? –

@EgorGromadskiy Вы имеете в виду о 'Error/Warning' подробнее – Jamal

Когда ваше приложение выходит из строя, вы видите окно с исключениями? Вы отлаживали приложение, чтобы найти, где именно происходит сбой приложения? –

Если SplashActivity запускает номе t после сбоев я предлагаю вам прокомментировать следующее.

На MainActivity в OnCreate, чтобы сузить проблему:

UserDialogs.Init (это);
SetXLabsInitialization();

Возможно, что один из них требует наличия сборок, которых нет.

Если эти инициализации не нарушают его, то ищите ошибки Xaml в журнале выходных данных диагностики Xamarin.

Я удалил «пакеты» в проекте PCL, а затем добавил еще раз, который показывал пакет «Retarget». Он решил проблему, когда приложение запускается. – Jamal
