Apps App to intercept network traffic and change responses

[Juo]

Hi,

Can anyone tell me if it is possible to develop an android app that when running (probably as a Service), monitors incoming network traffic (http responses etc), and change the content of the responses? Has to be without requiring rooting the device

Applications might be netnanny type stuff, where you can stop profane language appearing on your kids phone, on their facebook or instagram accounts etc - it detects certain posts and blocks the content by changing the http response. (Oh and would also need to work over https as well as http

It looks like that this is possible in iOS by using NSURLProtocol, but I don't see an Android equivalent.

I think its possible on a rooted device, but otherwise not possible. I have tried a basic proxy server running locally, but that requires setting the proxy settings, which then means the phone can't access remote network.

Thanks for any help

Maybe apps like 'Kids Place' or 'Funamo' are viable alternatives for what you're looking for? Plenty of other similar apps on Google Play if you do a search for 'parental control' or 'content filtering'.
