存储视频，图像和音频文件不能被其他人访问 [英] Storing videos, images and audio files that can not be accesses by others

问题描述

我开发例如WhatsApp聊天应用。在此应用程序用户可以发送视频，图像和音频文件给其他用户。现在的问题是 - 我的客户希望这些媒体内容的私人保持我的应用程序。它不能被画廊和用户读取甚至无法直接看到他们的SD卡。这些媒体文件，只要在我们的应用程序可见。

I am developing a chat application like whatsapp. In this app user can send videos, images and audio files to other users. Now the problem is - my client wants to keep all these media content private to my application. It can not be read by gallery and user can not even see them from sdcard directly. Those media files should be visible in our application only.

第一个解决方案是将所有的文件存储在内部存储设备。但是，这是不可取的，因为视频和图像将填补内部存储和用户将无法下载更多的应用程序没有内部存储器。

The first solution is to store all files in internal storage. But this is not advisable as videos and images will fill up the internal storage and user wont be able to download more apps without internal memory.

任何人都可以给我建议，我可以用它让我的私人数据的任何其他的方法呢？

Can anyone suggest me any other approach which I can use to make my data private?
