    We need a cross-platform app (for iOS and Android) that will engage an ad-hoc mode in the wireless devices in order to “discover” peers within the mobile device’s WiFi range. When a peer (someone using the same app) is “discovered” within range, the mobile devices will communicate as peer-to-peer (P2P) without involving central access point like a router. This isn"t a file transfer/sharing app. Instead, it’s a peer discovering app only. It will be similar to creating an ad hoc WiFi network between iOS and Android devices, but without the transferring of files between the mobile devices. We only need it to be able to discover and identify peers. CrossPlatform:The apps need to be cross platform for iOS and Android. For clarification, on an iOS device, the app will need to be able to discover peers that are using the app on both iOS devices and Android devices. Similarly, from an Android device, the app will need to be able to discover peers that are using the app on both Android devices and iOS devices. Hardware: Newer iOS devices (like iPhone 5 and newer) have the hardware to enable AirDrop to create a type of ad hoc WiFi network. Similarly, newer Android devices have the hardware to use WiFi Direct to form an ad hoc WiFi network. This app does not need to work on older mobile devices that do not have the hardware to create ad hoc WiFi networks. Unique Identifier: When the user opens the app, the app will either assign or let the user select some type of unique identifier. (We don’t care what the unique identifier is but the user should be able to see what unique identifies is assigned.) Share Unique Identifier: When the app is running, the mobile device needs to “share” the Unique Identifier with the peers. Ideally, it would “share” the Unique Identifier by broadcasting it wirelessly, like broadcasting an SSID. If that won’t work, it should “share” the Unique Identifier after the peers have found each other. Also, it would be great if the mobile device could broadcast/share the current date. Discover Peers: When the app is running, it will also be looking (via WiFi) for other mobile devices running the same app. Identify Peers: When the app finds (via WiFi) another device running the same app, it should be able to see and display the information Unique Identifier that the peer is broadcasting/sharing.Log/History of Peers: The app should create a log/history of the peers it has found. The log/history will need to include the Unique Identifier of the peer and the date the peer was found.We won"t be submitted this app to Apple or the Google Play. This is a functionality test for a different app project.

    Hi,I have an SDL C++ Android game. With the latest SDL 2.0 and SDL_ttf, SDL_image, SDL_mixer. I use the latest Android SDK and NDK. I target the same game apk to multiple phones/devices (from OS 2.2 and later). To do this each time the game is first run it downloads the correct resources from my server. The problems start when the c++ SDL game loads.The problem is that Samsung Store keeps rejecting my game at their online store because of some errors they find (2 errors).1) [Execution Error] Unable to Launch Application2) Sound Effects is occurred in Hold mode.I dont have the time to find/fix this, so I need an Android NDK/SDL expert to see the debug txt files, locate the problems and suggest an easy solution.Also I want a way to show ads (admob) when showing the SDL game (maybe on top?).Thanks,

    I need an app created that will allow me to add single click widgets to my home screen. In the app, I need to be able to type out the GET or POST commands, assign it to the widget, and be able to add a custom icon for the widget. When I click on the widget button, I do not want it to open an app or a webpage, just show a toast, that the command was successfully sent. I need to have an unlimited amount of commands and buttons. I already had an app created that allows this, but only allows one command, so I can only have one button which no longer functions for me needs.

I need a basic app that will pick up live feeds from multiple web cams based on known IP addresses, and display them on the screen of the device as either full screen or four cameras per screen or eight cameras per screen. Ideally the location of each camera will be reflected on googlemap, and be searchable by address.
