One of the awkward things happened to me during job interview. Long ago I had an interview for a developer position and the position was limited to the citizens who has secuirty clearance. However, after answering all the technical questions, I was asked to develop an app for employee phone directory and according to the offering job entity it should take about 20-30 minutes. I opened my laptop and start developing, when it was the time of compiling my IDE Visual Studio crashed and it took me two days to fix Visual Studio (32bit - 64-bit, hardware and OS version "DLL Files Problem" problem. In addition, it was Visual Studio Community not the supported one :) ). I sent the app two or three days later to the employer but I did not heared from the interviewee again nor received and offer. The app can be downloaded from the link below.

Phone Directory for Employee

In 2012-2013 I tried this mobile app as a project for my Distributed Unix Operating System, it uses REST web services as an API The App I do not know why the web service url is stored in the code as "&ht=t&ht=i&" + "ht=cp&ht=fl&ht=h&api_key=YOUR_API_KEY" in another version I have in an old computer YOUR_API_KEY is replaced by a number. I remember that my project was not functioning on the submission day, I got B while all my classmates got A and A+. The problem in my code was when I past the web service url or link and compile it gives me URI error. I searched the JAVA reference manual, documentation, web sources and it did not solve the problem, I did not develop a mobile app since that date. In Nov 2017 and in 2018, I was asked to develop App by many, and I do not know why the request was mobile Apps. By the way, it is the same source code of the project in the book Android 6 for Programmers, 3/e. I used it as a start point but it did not work out for me. Additionally, I was the only student who study this course in a section that has only one student (ME) and the section costs approximately 50,000 SAR (less than $15,000). I attended the section with a group of students who taking the course by network (distance learning) but they were full time regular students in another location for free.
