Camera
======
The :class:`Camera` is to capture pictures and make videos.
.. note::
- On Android the `CAMERA` , `WRITE_EXTERNAL_STORAGE`,
`READ_EXTERNAL_STORAGE` permissions are needed.
Simple Examples
---------------
Setup callback function.
>>> from os.path import exists, join
>>> from plyer import camera
>>> def camera_callback(filepath):
>>> if(exists(filepath)):
>>> print "saved"
>>> else:
>>> print "unable to save."
>>> filepath = 'path/to/your/file'
>>> # e.g: filepath = join(App.get_running_app().user_data_dir, file_name)
To take picture::
>>> file_name = "test.jpg"
>>> camera.take_picture(filename=file_name,
>>> on_complete=camera_callback)
Ta take a video::
>>> file_name = "test.mp4"
>>> camera.take_video(filename=file_name,
>>> on_complete=camera_callback)
Supported Platforms
