Android 如何获取文件的确切路径以将其转换为二进制文件？http://img4.imagetitan.com/img.php?image=11_logcat.png

经过多次搜索，我找到了文件的完整路径，但在将其转换为二进制文件时，出现了“NotFoundException”，请帮助

我的密码是

一,

二,

} }

//我在文件路径上遇到错误 //编写getGalleryDetails的CommonHelper类

三,

Log.e（“byte”，bytes.toString（））； 输出=空

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } finally {
        try {
        inputStream.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    return bytes;
}

请查看标题中的上述logcate链接请帮助我…提前感谢

fullpath

什么是

bytes=CommonHelper.getGalleryDetails（fullpath）；}？
我在文件路径上遇到错误
。这是一个错误。请显示日志猫。我已经上传了日志猫。请查看greenapps
。经过大量搜索，我找到了文件的完整路径。哪个文件？你能不能先解释一下这个代码应该做什么或者用户应该做什么？你仍然没有说出完整的路径是什么。你没有告诉我你犯了什么错误。你没有发布日志。
