我使用plyer开发kivy应用程序。通过buildozer构建并在android上启动应用程序成功，但是当我按下启动摄像头的按钮时应用程序崩溃，并且在logcat中没有输出任何内容。当我在kivylauncher中执行相同的代码时，我的工作没有问题。即使我用加速度计测试它也很相似。
我认为使用plyer构建应用程序时，必要的设置可能会很短。

我担心“异常：未找到android lib。”。

这是p4a / pyjnius中的bug。您可以使用旧的工具链，直到它被修复。
答案 1 :(得分：0)
在调查之后，我明白它在plyer.platform.android中崩溃了。 init .py。
它似乎在activivity = PythonActivity.mActivity中崩溃，但无法处理异常。
--- plyer.platform.android.__init__.py ---
from os import environ
from jnius import autoclass
ANDROID_VERSION = autoclass('android.os.Build$VERSION')
SDK_INT = ANDROID_VERSION.SDK_INT
print('ANDROID_VERSION = {}'.format(SDK_INT))
if 'PYTHON_SERVICE_ARGUMENT' in environ:
print('test-1-1')
PythonService = autoclass('org.renpy.android.PythonService')
print('test-1-2')
activity = PythonService.mService
print('test-1-3')
else:
print('test-2-1')
PythonActivity = autoclass('org.renpy.android.PythonActivity')
print('test-2-2')
activity = PythonActivity.mActivity
print('test-2-3')
