本文介绍了一个简单的Android应用程序，用于启动相机拍摄照片，并保存为指定路径下的文件。文章详细展示了如何创建一个活动（Activity），设置拍照请求码，指定图片输出路径，并在拍摄完成后处理所拍图片。


public class CameraActivity extends Activity {
	private static int TAKE_PICTURE = 1;
	private Uri outputFileUri;
	private File file;
	private String filename,filepath;
	private Bitmap bmp = null;	

	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		saveFullImage();
	}

	private void saveFullImage() {

		filename = String.valueOf("img-imagename" + ".jpg");
		Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
		File f = new File(Environment.getExternalStorageDirectory()
				+ "/Images");
		if (!f.exists()) {
			f.mkdirs();
		}

		filepath = f.getPath();
		File file = new File(filepath, filename);
		outputFileUri = Uri.fromFile(file);

		intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
		startActivityForResult(intent, TAKE_PICTURE);

	}

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

		if (requestCode == TAKE_PICTURE) {
			try {
				file = new File(filepath, filename);
				FileInputStream inputStream = null;
				inputStream = new FileInputStream(file);
				bmp = BitmapFactory.decodeStream(inputStream);//得到的bitmap对象
			} catch (FileNotFoundException e) {
				e.printStackTrace();
			}
						Intent i = new Intent(CameraActivity.this,
					XXXXActivity.class);
			startActivity(i);
			this.finish();
		}
	}

}
