Encrypting DropBox file using Android DropBox API

I have got the direction creation and file upload working in android usin开发者_如何学编程g the dropbox api. The file I want to store can contain personal information for synchronisation purposes between the phone and drop box.

Due to this, is it possible to encrypt the file or have I have I just got to encrypt the data before it is submitted into dropbox.

Thanks for any help you can provide.

You can and you should obfuscate your code so people won't see your app and secret keys. You can do so by yourself or use some help from ProGuard or JBCO.

I have never tried JBCO, but i know PrGuard can do obfuscation and sometimes some code optimization.

JBCO which stands for Java ByteCode Obfuscation is a bit more agressive and does some bytecode obfuscation. It's really hard to read.
