3. Android - Camera
4. Basics of Camera
5. The Android framework includes support for various cameras and camera features available on devices, allowing you to capture pictures and videos in your applications. This presentation discusses a quick, simple approach to image and video capture and outlines an advanced approach for creating custom camera experiences for your users. Basics of Camera
6. Manifest Declarations
7. Manifest Declarations Before starting development on your application with the Camera API, you should make sure your manifest has the appropriate declarations to allow use of camera hardware and other related features.
8. Cont. Before starting development on your application with the Camera API, you should make sure your manifest has the appropriate declarations to allow use of camera hardware and other related features. • Camera Permission
9. Cont. Before starting development on your application with the Camera API, you should make sure your manifest has the appropriate declarations to allow use of camera hardware and other related features. • Camera Permission • Camera Features
10. Cont. Before starting development on your application with the Camera API, you should make sure your manifest has the appropriate declarations to allow use of camera hardware and other related features. • Camera Permission • Camera Features • Storage Permission

12. Cont. Before starting development on your application with the Camera API, you should make sure your manifest has the appropriate declarations to allow use of camera hardware and other related features. • Camera Permission • Camera Features • Storage Permission • Audio Recording Permission • Location Permission
13. Cont. Camera Permission - Your application must request permission to use a device camera. For example: <uses-permission android:name="android.permission.CAMERA" />
14. Cont. Camera Features - Your application must also declare use of camera features. For example: <uses-feature android:name="android.hardware.camera" />
15. Cont. Storage Permission - If your application saves images or videos to the device's external storage (SD Card), you must also specify this in the manifest. For example: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
16. Cont. Audio Recording - For recording audio with video capture, your application must request the audio capture permission. For example: <uses-permission android:name="android.permission.RECORD_AUDIO" />
17. Cont. Location Permission - If your application tags images with GPS location information, you must request the ACCESS_FINE_LOCATION permission. For example: <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
18. Using existing camera apps
19. Using existing camera apps A quick way to enable taking pictures or videos in your application without a lot of extra code is to use an Intent to open an existing Android camera application. For example: Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
20. Building a camera app
21. Building a camera app Some developers may require a camera user interface that is customized to the look of their application or provides special features. Writing your own picture-taking code can provide a more compelling experience for your users.
22. Cont. The general steps for creating a custom camera interface for your application are as follows:

32. Android - Bluetooth
33. Bluetooth is a way to send or receive data between two different devices. The Android platform includes support for the Bluetooth which allows a device to wirelessly exchange data with other Bluetooth devices. The application framework provides access to the Bluetooth functionality through the Android Bluetooth APIs. Bluetooth
34. Using the Bluetooth APIs, an Android application can perform the following: Cont.
35. Using the Bluetooth APIs, an Android application can perform the following: • Scan for other Bluetooth devices Cont.
36. Using the Bluetooth APIs, an Android application can perform the following: • Scan for other Bluetooth devices • Paired Bluetooth devices Cont.
37. Using the Bluetooth APIs, an Android application can perform the following: • Scan for other Bluetooth devices • Paired Bluetooth devices • Connect to other devices through service discovery Cont.
38. Using the Bluetooth APIs, an Android application can perform the following: • Scan for other Bluetooth devices • Paired Bluetooth devices • Connect to other devices through service discovery • Transfer data to and from other devices Cont.
39. Bluetooth Permissions
40. Cont. You need this permission to perform any Bluetooth communication, such as requesting a connection, accepting a connection, and transferring data. <uses-permission android:name="android.permission.BLUETOOTH" />
41. Cont. The other permission that you must declare is location permission. A location permission is required because Bluetooth scans can be used to gather information about the location of the user. <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
