Take picture
============
.. author:: Mathieu Virbel <mat@kivy.org>
Little example to demonstrate how to start an Intent, and get the result.
When you use the Android.startActivityForResult(), the result will be dispatched
into onActivityResult. You can catch the event with the android.activity API
from python-for-android project.
If you want to compile it, don't forget to add the CAMERA permission::
./build.py --name 'TakePicture' --package org.test.takepicture \
--permission CAMERA --version 1 \
--private ~/code/kivy/examples/android/takepicture \
debug installd
