I have an existing application called "GPSTracking SMS Commander" that store predefined commands ready to send by SMS. The list of commands include: "command name" - to display to the user "command text" - to be send by SMS the user can add, update, delete commands. and use param inside a command. I want to change the application so the init commands will come from a remote XML file. Now, all the init commands are included inside the application. I want to let the user choose device and language and import all the commands list from the remote XML file. also I want to set fixed buttons on the main screen (like a remote control) and let the user choose favorites commands from the list and associate them to each button. also add a login screen and authentication from my site users. https://play.google.com/store/apps/details?id=il.co.gpstracking.gpstrackingsmscommander https://itunes.apple.com/us/app/gpstracking-sms-commander/id987921221?mt=8

I have software that scrapes data from Stubhub, but they use js code to monitor user behavior to thwart repeated login. They are constantly updating the code - so I need a method to allow login. The program is written in Java, it does everything I need it to, but the login process needs to be solved. 1. You need to have a United States IP to access Stubhub 2. The Stubhhub API will not work for this program - another method must be used 3. this is what my programmer wrote about his last attempt to get this working: because I researched stubhub's code and made really stable sales getting, but stubhub changed the server and client parts to totally new idea so now it is not possible to do something because UI code is obfuscated.... 4. Stubhub changes/updates frequently - you would need to come up with something flexible 5. if possible, log into stubhub and see how the process works before you bid on project thanks

Write a music player app in Android, according to my detailed design. This is for a proprietary system that allows people to share music with each other. You will be under a legal NDA agreement covering both the code and the concept. The most important skill for you will be the ability to implement my interface ideas, which include graphical cues to browse through music content. Implementing this involves things such as drawing graphic elements at particular positions on the screen, and accepting swipe gestures that scroll the graphics in _any_ direction, using aesthetically pleasing physics effects such as inertia and friction. The Android device will also communicate with a server, as well as direct peer-to-peer communication between Android devices. It is okay if you do not have skills for this part, as I will either handle this, or else hire it out to a back-end developer. I, myself, am a C++, Java, and Javascript developer, but am new to Android development. So...
