Do we need to do anything with the default libs.versions.toml

For stage 1: Show me the most basic setup which we can compile verify and then move on.
@done Send out a preview video teaching students how to set the current location in their emulator.
On some emulators you have to:
- open the built in Google Maps app
- click on the "center on current location button" - exit the Google maps app
- open emulator settings (location)
- push the set location button
done: Send out a pre-class video before class to demonstrate on your own computer/emulator as this is the #1 issue I've had students asked me about on previous semesters
@done: Send out a video checklist displaying examples of:
How to start and stop tracking location changes?
For example: app loads and the initial location is detected.
Some time passes and the user's location updates. The app automatically detects the change and does something with the new location (example: output to the screen).
User can push a button to tell the app to stop auto-detecting location changes .
How programmatically update the map to center on the user's location? Examples include:
User enters a lat, long into text boxes and pressed button.
When button pressed, map updates to be centered on the specified lat/lng
Lab 3: How to programmatically add a marker to the map and add an annotation to that marker?
→ user enters lat, long into text boxes and pressed button.
When button pressed, marker put on location specified.
User enters a new lat lng and marker is added to the map (so there are 2 markers in total)
Lab 4: How to obtain the location from the device and center the map on that location
- user pushes a button to get their current location
- device retrieves location
- after retrieving location, map moves be centered on their location?
Requirements: ( Map to labs by the same number)
Prompt: We are now going to write a Lab Instruction Work book to deliver these requiremennts.
We are going to build on top of the App Built in the Lab 1: Location tracking so all the foundational elements of the app are in app. The Code you write must work with the precedent
MainActivity.kt
activity_main.xml
In all cases: Respect and follow Android Application Development Best Practices.
use View Bindings as View Bindings are the new best practice in Android Kotlin Application Development. Do not in any case use findViewByID which is old and deprecated.
use set onClick Listeners Function in KOTLIN, which is the new best practice in Android Kotlin Application Development. DO NOT use Button Click Handling since Button Click Handling is old and deprecated.
### Double check that there are no references to findViewById. Use View Bindings as View Bindings are the new best practice in Android Kotlin Application Development. Do not in any case use findViewByID which is old and deprecated.
Use set onClick Listeners Function in KOTLIN, which is the new best practice in Android Kotlin Application Development. DO NOT use Button Click Handling since Button Click Handling is old and deprecated.
Requirement 1: CLICK a BUTTON to programmatically center the Map on LONG and LAT specified in TEXT BOXES.
Requirement 2: Add Markers to the map when user enters LONG and LAT in TEXT BOXES and clicks a Button. Add Annotations to Markers. For example: Royal Ontario Museum. The markers accummulate - markers previous there must remain there.
Requirement 3: Tap the Map to Drop a Marker. Provide a facility to add annotations to the markers which include longitude and lattitude. The markers are cumulative. What was there before, stays there.
Upgrade for phase 2: Add a button to clear all markers.
