问题 Suppose I am developing a mobile application that makes calls to an API server. The API server is secured by an API Key. I cannot hard-code the API Key inside the mobile application because it can be stolen. How can I protect the API key? 回答1: How is that problem usually solved? (It sounds like the API-key you are trying to protect is for an API service that you don't own.) One approach is by using an authentication server. The private API-key is kept on the authentication server and only

问题 I have a website that will mainly be used for large screen monitors on the desktop. Within the page I will have various content sections, but I also want to have a mobile app area within a div that will display to the user how items in a mobile app might look differently on different mobile phones. Looking at specs of some phones I see: iPhone 7 (4.7 inch) - 1,334 x 750 pixels (326 ppi) iPhone 7 (5.5 inch) - 1,920 x 1080 pixels (401 ppi) Samsung Galaxy S7 - 2,560 x 1440 pixels (577 ppi)

问题 I'm trying to make a peer to peer Javascript game that can be played on mobile browsers. I have been able to successfully set up a p2p connection between two phones within my local WiFi network. I am unable to connect two phones over mobile networks or one on WiFi and one on a mobile network. I tried turning off my Windows firewall and could not connect my PC to my phone on a mobile network. I tried having both peers set up their own data channels and set negotiated. I've read that 80% to 90%

问题 I have a fixed image that overlays a page when the user is in the act of scrolling a touch screen (mobile). I want to make that image "unclickable" or "inactive" or whatever, so that if a user touches and drags from that image, the page behind it still scrolls as if the image weren't there "blocking" the interaction. Is this possible? If need be, I could try to provide screen shots exemplifying what I mean. Thanks! 回答1: Setting CSS - pointer-events: none should remove any mouse interaction

问题 I have an idea to build an android application for dumb people which can be helped to answer phone calls. I thought to convert the text into voice and then transfer through call stream.Is it still not possible to play audio so that other party can hear during a phone call in android platforms 回答1: Sorry, the short answer still seems to be no. I would love to be shown wrong on this. It seems however that the issue goes back to the hardware level and even when that's exposed, Android isn't
