How to take picture in android mobile

我在Google上查找“android take picture”得到一堆帖子告诉你怎样自己写代码去拍照并存储。事实上我想调用系统的Activity去拍照，我需要的是系统的Activity拍照后告诉我图片存储路径即可。

实际上系统有个MediaStore中记录着这个Activity的名字 MediaStore.ACTION_IMAGE_CAPTURE

在Google Code Search中查一下

MediaStore.java

/**
     * Standard Intent action that can be sent to have the camera application
     * capture an image and return it.
     * 

     * The caller may pass an extra EXTRA_OUTPUT to control where this image will be written.
     * If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap
     * object in the extra field. This is useful for applications that only need a small image.
     * If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri
     * value of EXTRA_OUTPUT.
     * @see #EXTRA_OUTPUT
     * @see #EXTRA_VIDEO_QUALITY
     */
    public final static String ACTION_IMAGE_CAPTURE = "android.media.action.IMAGE_CAPTURE";

SlideEditorActivity.java

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            //..............
            case MENU_TAKE_PICTURE:
                intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent, REQUEST_CODE_TAKE_PICTURE);
                break;
            //....................
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode != RESULT_OK) {
            return;
        }

        switch(requestCode) {
            //..............
            case REQUEST_CODE_TAKE_PICTURE:
                Bitmap bitmap = (Bitmap) data.getParcelableExtra("data");
            //....................
