I am using Kivy and buildozer on OS X (10.10.1), but I cannot get a Kivy camera application to run on my Android device. Kivy applications that do not use camera are fine. Code is below, and I can also post the buildozer spec file and debug information.
#================================
import kivy kivy.require('1.4.0') from kivy.app import App from kivy.uix.widget import Widget from kivy.uix.camera import Camera from kivy.uix.button import Button from kivy.core.window import Window
class MyApp(App):
def doscreenshot(self,*largs):
Window.screenshot(name='screenshot%(counter)04d.jpg')
def build(self):
camwidget = Widget() #Create a camera Widget
cam = Camera() #Get the camera
cam=Camera(resolution=(640,480), size=(500,500))
cam.play=True #Start the camera
camwidget.add_widget(cam)
return camwidget
if __name__ == '__main__':
MyApp().run()
