I learned to code Java and Android from scratch andthis is my first product after 8 months of code crunching. The ideafor this app came to me when my car was double-parked by anothercar, blocking my way out, but without any way to reach the owner. Ihope this app will begin to be useful if everyone starts to useit.If there is any problem, please contact me [email protected]. I will try my best to solve it.
