  <li><strong>Quick Picture or Customized Camera</strong> - How will your application use the

camera? Are you just interested in snapping a quick picture or video clip, or will your application

provide a new way to use cameras? For a getting a quick snap or clip, consider

<a href="#camera-apps">Using Existing Camera Apps</a>. For developing a customized camera feature, check

out the <a href="#custom-camera">Building a Camera App</a> section.</li>

  <li><strong>Storage</strong> - Are the images or videos your application generates intended to be

<pre>

<uses-permission android:name="android.permission.CAMERA" />

</pre>

  <p class="note"><strong>Note:</strong> If you are using the camera <a href="#intents">via an

intent</a>, your application does not need to request this permission.</p>

  <p class="note"><strong>Note:</strong> If you are using the camera <a href="#camera-apps">by

  </li>

  <li><strong>Camera Features</strong> - Your application must also declare use of camera features,

for example:

</ul>

<h2 id="intents">Using Existing Camera Apps</h2>

<h2 id="camera-apps">Using Existing Camera Apps</h2>

<p>A quick way to enable taking pictures or videos in your application without a lot of extra code

is to use an {@link android.content.Intent} to invoke an existing Android camera application. A

camera intent makes a request to capture a picture or video clip through an existing camera app and

then returns control back to your application. This section shows you how to capture an image or

video using this technique.</p>

<p>The procedure for invoking a camera intent follows these general steps:</p>

<ol>

  <li><strong>Compose a Camera Intent</strong> - Create an {@link android.content.Intent} that

requests an image or video, using one of these intent types:

    <ul>

      <li>{@link android.provider.MediaStore#ACTION_IMAGE_CAPTURE MediaStore.ACTION_IMAGE_CAPTURE} -

Intent action type for requesting an image from an existing camera application.</li>

      <li>{@link android.provider.MediaStore#ACTION_VIDEO_CAPTURE MediaStore.ACTION_VIDEO_CAPTURE} -

Intent action type for requesting a video from an existing camera application. </li>

    </ul>

  </li>

  <li><strong>Start the Camera Intent</strong> - Use the {@link

android.app.Activity#startActivityForResult(android.content.Intent, int) startActivityForResult()}

method to execute the camera intent. After you start the intent, the Camera application user

interface appears on the device screen and the user can take a picture or video.</li>

  <li><strong>Receive the Intent Result</strong> - Set up an {@link

android.app.Activity#onActivityResult(int, int, android.content.Intent) onActivityResult()} method

in your application to receive the callback and data from the camera intent. When the user

finishes taking a picture or video (or cancels the operation), the system calls this method.</li>

</ol>

<h3 id="intent-image">Image capture intent</h3>

<p>Capturing images using a camera intent is quick way to enable your application to take pictures

with minimal coding. An image capture intent can include the following extra information:</p>

<ul>

  <li>{@link android.provider.MediaStore#EXTRA_OUTPUT MediaStore.EXTRA_OUTPUT} - This setting

requires a {@link android.net.Uri} object specifying a path and file name where you'd like to

save the picture. This setting is optional but strongly recommended. If you do not specify this

value, the camera application saves the requested picture in the default location with a default

name, specified in the returned intent's {@link android.content.Intent#getData() Intent.getData()}

field.</li>

</ul>

<p>The following example demonstrates how to construct a image capture intent and execute it.

The {@code getOutputMediaFileUri()} method in this example refers to the sample code shown in <a

href= "#saving-media">Saving Media Files</a>.</p>

<pre>

private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;

private Uri fileUri;

@Override

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    // create Intent to take a picture and return control to the calling application

    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image

    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name

    // start the image capture Intent

    startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

}

</pre>

<p>When the {@link android.app.Activity#startActivityForResult(android.content.Intent, int)

startActivityForResult()} method is executed, users see a camera application interface.

After the user finishes taking a picture (or cancels the operation), the user interface returns to

your application, and you must intercept the {@link

android.app.Activity#onActivityResult(int, int, android.content.Intent) onActivityResult()}

method to receive the result of the intent and continue your application execution. For information

on how to receive the completed intent, see <a href="#intent-receive">Receiving camera intent

result</a>.</p>

<h3 id="intent-video">Video capture intent</h3>

<p>Capturing video using a camera intent is a quick way to enable your application to take videos

with minimal coding. A video capture intent can include the following extra information:</p>

<ul>

  <li>{@link android.provider.MediaStore#EXTRA_OUTPUT MediaStore.EXTRA_OUTPUT} - This setting

requires a {@link android.net.Uri} specifying a path and file name where you'd like to save the

video. This setting is optional but strongly recommended. If you do not specify this value, the

Camera application saves the requested video in the default location with a default name, specified

in the returned intent's {@link android.content.Intent#getData() Intent.getData()} field.</li>

  <li>{@link android.provider.MediaStore#EXTRA_VIDEO_QUALITY MediaStore.EXTRA_VIDEO_QUALITY} -

This value can be 0 for lowest quality and smallest file size or 1 for highest quality and

larger file size.</li>

  <li>{@link android.provider.MediaStore#EXTRA_DURATION_LIMIT MediaStore.EXTRA_DURATION_LIMIT} -

Set this value to limit the length, in seconds, of the video being captured.</li>

  <li>{@link android.provider.MediaStore#EXTRA_SIZE_LIMIT MediaStore.EXTRA_SIZE_LIMIT} -

Set this value to limit the file size, in bytes, of the video being captured.

</li>

</ul>

<p>The following example demonstrates how to construct a video capture intent and execute it.

The {@code getOutputMediaFileUri()} method in this example refers to the sample code shown in <a

href= "#saving-media">Saving Media Files</a>.</p>

<pre>

private static final int CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE = 200;

private Uri fileUri;

@Override

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    //create new Intent

    Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);

    fileUri = getOutputMediaFileUri(MEDIA_TYPE_VIDEO);  // create a file to save the video

    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);  // set the image file name

    intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); // set the video image quality to high

    // start the Video Capture Intent

    startActivityForResult(intent, CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE);

}

</pre>

<p>When the {@link

android.app.Activity#startActivityForResult(android.content.Intent, int)

startActivityForResult()} method is executed, users see a modified camera application interface.

After the user finishes taking a video (or cancels the operation), the user interface

returns to your application, and you must intercept the {@link

android.app.Activity#onActivityResult(int, int, android.content.Intent) onActivityResult()}

method to receive the result of the intent and continue your application execution. For information

on how to receive the completed intent, see the next section.</p>

<h3 id="intent-receive">Receiving camera intent result</h3>

<p>Once you have constructed and executed an image or video camera intent, your application must be

configured to receive the result of the intent. This section shows you how to intercept the callback

from a camera intent so your application can do further processing of the captured image or

video.</p>

<p>In order to receive the result of an intent, you must override the {@link

android.app.Activity#onActivityResult(int, int, android.content.Intent) onActivityResult()} in the

activity that started the intent. The following example demonstrates how to override {@link

android.app.Activity#onActivityResult(int, int, android.content.Intent) onActivityResult()} to

capture the result of the <a href="#intent-image">image camera intent</a> or <a

href="#intent-video">video camera intent</a> examples shown in the previous sections.</p>

<pre>

private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;

private static final int CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE = 200;

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {

        if (resultCode == RESULT_OK) {

            // Image captured and saved to fileUri specified in the Intent

            Toast.makeText(this, "Image saved to:\n" +

                     data.getData(), Toast.LENGTH_LONG).show();

        } else if (resultCode == RESULT_CANCELED) {

            // User cancelled the image capture

        } else {

            // Image capture failed, advise user

        }

    }

    if (requestCode == CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE) {

        if (resultCode == RESULT_OK) {

            // Video captured and saved to fileUri specified in the Intent

            Toast.makeText(this, "Video saved to:\n" +

                     data.getData(), Toast.LENGTH_LONG).show();

        } else if (resultCode == RESULT_CANCELED) {

            // User cancelled the video capture

        } else {

            // Video capture failed, advise user

        }

    }

}

</pre>

<p>Once your activity receives a successful result, the captured image or video is available in the

specified location for your application to access.</p>

is to use an {@link android.content.Intent} to invoke an existing Android camera application.
