使用内部存储和加密用法保护Android应用程序中下载的文件的安全吗？

Question

I am working on an Android application which downloads files in External storage.

I want to download them in internal storage and encrypt them so they become secure even with a rooted device. I found that we can work with internal storage and encrypting the files and to use them with external intents we use content-provider.

Dose some one worked with this kind of stuff ? (internal-storage + encrypting + decrypting + content-providers).

thanks

You can use the download manager to download files using async task. After that encrypt and decrypt that files. please refer How to encrypt file from SD card using AES in Android?
