Re: [android-developers] Email Signup - Terms of Service and Privacy Policy

[Henrik]

OK, thanks. I guess I'll have to, because there are no guidelines on this 
topic - at least I can't find any. I also use the EU Cookie Consent Policy 
message at launch, however, it's also not black and white if you need it or 
not (EU is not really sure what they want).

[android-developers] Screen filter app

[Guillermo Rodriguez]

Hi,

Is it possible to create an app that works as a real time screen color or 
position filter? For example to make all the screen look sepia or black and 
white or do ripples or maybe to flip it 90'... but keep the phone operating 
normally?

I mean as a transformation layer just before rendering...

Re: [android-developers] goldwasser micali encryption implementation in android studio

[hezaveh]

Hi,

I want an android app, one EditText to enter input. and then a button, by 
clicking the button it calls encrypt method and then a textview shows the 
encrypted message. The other button to decrypt the message, calls decrypt 
method. last textview shows the dencrypted message which is same as the 
input.

Here is a link that implement RSA encryption (
https://sites.google.com/site/mobilesecuritylabware/3-data-location-privacy/lab-activity/cryptography/cryptography-mobile-labs/encryption-decryption/2-lab-activity/lab2-rsa-encryption-program-android-studio).
 
I want exactly same for goldwasser micali.

Thanks
