3. Intro
 Here I try to build a camera which will work or
capture image by voice or sound command.
 Before enabling application to use cameras on
Android devices, we should consider a few
questions about how app intends to use this
hardware feature.
 Camera requirement
 Quick picture or customized camera
 Storage

4. Tools
 Eclipse
 ADT(Android Developer Tools)
 JRE
 JDK
 Android Virtual Emulator

5. Getting Started
 Camera Intent
 Compose a Camera Intent -Create an Intent that requests
an image or video, using one of these intent types:
MediaStore.ACTION_IMAGE_CAPTURE - Intent action type
for requesting an image from an existing camera application.
 Start the Camera Intent - Use the
startActivityForResult() method to execute the camera
intent. After starting the intent, the Camera application
user interface appears on the device screen and the user
can take a picture
 Receive the Intent Result - Set up an
OnActivityResult() method inapplication to receive the
callback and data from the camera intent. When the user
finishes taking a, the system calls this method.

6. Image capture intent
 Capturing images using a camera intent is quick way to enable application to
take pictures with minimal coding.
