Easy Trip planner

Build an android trip planner app similar as the link here = https://projectnotes.org/it-projects/trip-planner-in-android-with-source-code/
I’m in real hurry within 1 day if possible, there are some unsolved problems in the code provided in link above as the search destination wouldn’t pop out for inputting the place name.
It’s my project and I need to submit this Friday. Thank you in advance
