Have their own encrypted doc, XLS, PDF, JPG, TXT files, to the android device, calls for installed app to open these files decrypted before (encrypted files, decryption nature is not a problem), what do you want to be a decryption plug-in, I don't know how to do? I don't know is there any file open to monitor method?

Encryption is not the problem, the problem is the file is to install the app to play before, I the disclosure of the app (or plug-in) how to get the run,
