DESCRIPTION¶ ↑

This sample Android application demonstrates an approach for Camera usage.

USAGE¶ ↑

Add camera permission to your AndroidManifest.xml file¶ ↑

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

Start camera activity in the next way:¶ ↑

private static final int PICK_PICTURE_CAMERA_REQUEST = 1;

...

Intent i = new Intent(this, CameraActivity.class);
startActivityForResult(i, PICK_PICTURE_CAMERA_REQUEST);

You can touch the screen or press the trackboll button to get an image from camera.

To get the camera result image Uri use onActivityResult(int requestCode, int resultCode, Intent data) method:¶ ↑

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      super.onActivityResult(requestCode, resultCode, data);
      if (requestCode == PICK_PICTURE_CAMERA_REQUEST) {
          Uri imageUri = null;
          if (resultCode == RESULT_OK) {
              imageUri = data.getData();
          } else {
              showAlertDialog("Android Camera Demo", "No image taken!");
          }
          setImageTaken(imageUri);
      }
  }

If an Exception occured in the camera activity the resultCode will be RESULT_CANCELED and no data attached.
