Загадочная ошибка, когда я пытаюсь инициализировать Android Visualizer через Buildozer

5 голосов
/ 18 июня 2019

У меня есть некоторый существующий код на Python и я хочу перенести его на Android с помощью Kivy и Buildozer. Однако у меня есть зависимость от нативного класса Android 'Visualizer'. Мое приложение запускается правильно, но когда я нажимаю кнопку «Выполнить» в моем приложении, эта ошибка появляется, когда я использую следующий код в java 

new Visualizer(0);

или 

Visualizer = autoclass('[visualizer.class.....]')
v = Visualizer(0)

В питоне

Я предоставил все необходимые разрешения времени выполнения, такие как RECORD_AUDIO, MODIFY_AUDIO и INTERNET

My Buildozer config:
# (int) Target Android API, should be as high as possible.
android.api = 27

# (int) Minimum API your APK will support.
android.minapi = 21

# (int) Android SDK version to use
android.sdk = 27

# (str) Android NDK version to use
android.ndk = 17c

# (int) Android NDK API to use. This is the minimum API your app will support, it should usually match android.minapi.
android.ndk_api = 21

EDITED

Я также забыл упомянуть, что вышеупомянутый java-класс хорошо работает при развертывании через Android Studio
