Hi, This is an urgent project that needs to be fixed today. [Background] We have for the three last years been working with a freelancer to develop a restaurant system for ordering. The "system" is consisting of two different APK's. Menu APK and Admin APK. [Work flow of system] A guest enters our restaurant and is handed a menu and a Samsung/Huawei 10.1" tablet. On that tablet we have preinstalled the MENU APK. The guest can now browse our menu on the tablet and make orders that are being sent to the "Admin APK". In our kitchen and bar we have tablets where our staff can view incoming orders and process them easily. The guest can easily order more and/or pay their bill in the tablet. I have attached two videos below that shows how the system kind of works in real life. [The project] Debbuging/issue. 1. We have an "overload" issue that we can't figure out. When we have a lot of guests and a lot of orders at the same time the system halts/slows down and eventually crashes/not responding. It seems like the system puts a lot of pressure on the hardware when there is a lot of orders. We are using tablets from Samsung and huawei, and they all have quad core processors and 1,5gb-2gb of ram. Maybe the DB gets "locked" up in someway? I have the source code on hand for the developer I choose. I'm attaching a document with a link to Dropbox and three videos. Two videos show the workflow of the "system" so you can better understand how we are using the APK's. The third video shows you the problem we have with halting/slow system.

Hi, I see your video carefully and come to the conclusion that your client side i.e menu APK is not designed properly for delay response from SERVER i.e (System) ...its directly calling server from main thread which cause HANG and as delay increase android throws ANR crash i.e. if UI takes long to respond android system crash the APK with ANR flag. This is not easy to fix job as you think i.e. 1 day. It need proper checking of your current flow in code and fix it for background processing. Keep in mind that its FULLY CLIENT side i.e MENU APK issue. I need first code to see its complexity and then I can provide days to fix. I am very experienced developer of android with CLIENT/Server communication expertise too. Ehsan Ehsan

Hi Where is the server located? Is it on your network or the internet? How many users crash the app? Please provide the source code and server details if possible and I can get started. I cant promise you that it will be fixed today, as you can understand that I will need some time to go through the code and then troubleshoot the issue. But I will give my best to figure it out and fix it asap. Please message me interested. PS: After watching the third video, I realize its not the users that are causing the crash. Its some bad code. Please send me a messaage if interested, as I cant initiate a chat unless you do :) PS: I dont think this whole process is using a server, I think they are connecting to each other directly. THe admin is on windows, Are you using virtual android system to use it? Regards Priyanshu

Hi. I have seen the videos and I have understood the behavior of the apps. I was also able to see the error clearly. It can be the DB as you mention or a collapse of the real-time messages (which I imagine the apps must have). I can debug the apps and the backend to solve the problem, but I don't think I can finish it today because I must install the environments and learn about the 2 apps and the backend. The work will take me a few days. Regards.
