android mediastore参数,从 mediastore Android获取全屏幕缩略图

我一直得到错误的'类型： 2'尝试从mediastore获取FULL_SCREEN_KIND缩略图时。 我知道URI是一个有效的图像( 因为我已经提前thumbs了) 。 我的错误在哪里谢谢。

我的代码Long myURI = Long.parseLong(record.getString("FILE_ID"));

if (record.getString("FILE_TYPE").equalsIgnoreCase("image")) {

Bitmap bitmap = MediaStore.Images.Thumbnails.getThumbnail(mContext.getContentResolver(), myURI, MediaStore.Images.Thumbnails.FULL_SCREEN_KIND, (BitmapFactory.Options) null);

return bitmap;

}

else if (record.getString("FILE_TYPE").equalsIgnoreCase("video")) {

Bitmap bitmap = MediaStore.Video.Thumbnails.getThumbnail(mContext.getContentResolver(), myURI, MediaStore.Video.Thumbnails.FULL_SCREEN_KIND, (BitmapFactory.Options) null);

return bitmap;

}
