Как отлаживать при использовании ионного Emulate андроида

Question

Я создал приложение, используя ионным:

ionic start MyFirstApp blank 
cd MyFirstApp 
ionic serve 
ionic platform add android 
ionic build android 
ionic emulate android 

Все успешно, кроме шага эмулятора. Эмулятор загружается, но я получаю «К сожалению, MyFirstApp остановился». Все совершенно новое прямо из коробки, никаких изменений в коде.

Что дальше? Как отлаживать то, что пошло не так?

EDIT Это выход отображается, когда я звоню ionic build android:

EDIT 2 Это выход из android list avd

Available Android Virtual Devices: 
    Name: Nexus7 
    Device: Nexus 7 (Google) 
    Path: C:\Users\Colin\.android\avd\Nexus7.avd 
    Target: Android 4.4W (API level 20) 
Tag/ABI: android-wear/armeabi-v7a 
    Skin: WVGA800 

Answer 1

Пожалуйста, убедитесь, что вы создали правильный AVD конфигурации для эмулятора.

тип android list avd и посмотреть выход. Что такое первый avd? Если он показывает более старый уровень API (например, для: 7)

level 9 and higher is required, API level 15 API и высокий предпочтительный. Вы не можете использовать API 20 Android Wear AVD, поскольку он предназначен только для тестирования устройств износа.

Вы можете удалить существующие avd с помощью android delete avd -n Name (замените Name на свой).

создать с android create avd --name test15 --target android-15 --abi x86

убедитесь android list avd показывает ваш AVD является первым в списке.

• Я последовал за те же самые шаги, я использую окно, мой ionic build android выхода похож на твой; Я был в состоянии получить ionic emulate android работы с API-15, пожалуйста, смотрите ниже:

  

Answer 2

Намного проще/лучшее решение на мой взгляд, использовать хром: // инспектировать инструмент на хроме.

1. Запустите приложение на Android с помощью

   ионный запуск андроида

2. Открыть Chrome и перейти к: хром: // инспектировать - это список ваших подключенных устройств.

3. Осмотрите приложение, используя инструменты chrome dev, как если бы вы проверяли любую другую веб-страницу.
