android-获取原始联系人缩略图

我正在尝试检索原始联系人的照片.我可以成功获取给定原始联系人的高分辨率照片,但是当我想获取同一原始联系人的缩略图时,出现以下异常：

02-17 05:43:44.695: E/DatabaseUtils(4071): Writing exception to parcel

我正在使用RESTlet框架,但我认为这与此问题无关.

这是我的代码：

这里mHighResolution是一个布尔值,如果为false,它将生成该异常.正确时将显示照片.
所以,

mHighResolution == false -> exception
mHighResolution == true -> works fine

public InputStream getPhotoInputStream() {
        Uri uri = Uri.withAppendedPath(ContactsContract.RawContacts.CONTENT_URI, String.valueOf(mRawContactId));
        return ContactsContract.Contacts.openContactPhotoInputStream(contentResolver, uri, mHighResolution);
}

    @Override
    public void handle(Request request, Response response) {

        String type = request.getMethod().getName();
        String uid = (String) request.getAttributes().get("uid");

        if(type.equalsIgnoreCase("get"))
        {
            try {
                Representation r = processGet(uid);
                response.setEntity(r);
            } catch (NotFoundException e) {
                Log.e(TAG, e.getMessage(), e);
                response.setStatus(new Status(Status.CLIENT_ERROR_NOT_FOUND, e.getMessage()));
            } catch (IOException e) {
                Log.e(TAG, e.getMessage(), e);
                response.setStatus(new Status(Status.SERVER_ERROR_INTERNAL, e.getMessage()));           
            } 
        }

private Representation processGet(String uid) throws NotFoundException, IOException
{
    Photo photo = new Photo(mContext, uid);
    Representation representation = new InputRepresentation(photo.getPhotoInputStream());

    return representation;
}

解决方法:

缩略图照片将从联系人数据库保存在数据表中.

Android将照片保存为图像文件(高分辨率)或数据库中的斑点

要访问图像文件,可以使用我在问题中使用的方法.要访问数据库中的缩略图,可以使用以下代码：

public InputStream getPhotoThumbnailInputStream(String uid)
{
    final String[] projection = new String[]{Data.DATA15};
    final String selection = Data.RAW_CONTACT_ID + "=? AND " + Data.MIMETYPE + " =?";
    final String[] selectionArgs = new String[]{uid, android.provider.ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE};

    final Cursor cursor = contentResolver.query(Data.CONTENT_URI, projection, selection, selectionArgs, null);

    if(cursor.moveToFirst())
    {
        byte[] photo = cursor.getBlob(0);
        InputStream is = new ByteArrayInputStream(photo);
        cursor.close();
        return is;
    }
    else {
        Log.e(TAG, "Photo thumbnail not found for the given raw contact id.");
        cursor.close();
        return null;
    }
}
