Need Help/ Example and more Documentation with Maps Element

[Gugum]

I have now successfully created an application where the user can mark on the map and then fill in the information about the sign (survey).

the next step I want to create an android app for the survey application. I've tried several apps that provide the convert feature from website to apk, but everything has not worked (map does not show up).

currently I plan to create an app using the Inventor app or appybuilder, in the appinventor / appybuilder there are Maps element, but the constraints after I tried to find various information and examples I still do not understand how to use the element features.

my plan to make the project as follows

1.when the application runs, the map opens

2. the initial map contains information from json (featurescollection - Multipolygon).

3. Users can add markers on the map by shifting the map (not shifting marksign), where in the map view, in the middle there is marksign, then press the "add info" button.

4. after the user pressing the "add info" button, the form will appear on the side (like: place name, address, owner, etc.).

5. user then press the save button, and data info is stored in database server following its coordinates.

6. data from the database to then displayed again dipeta as marker (feature: Point).

considering the huge limitations of files allowed on appinventor, I plan to download Json (featurecollection - Multipolygon) data after the user first opens the application (http://puravidaapps.com/filebyfile.php). the data is then stored in the application so that when the user opens the next application, do not download the json data again. while json data for marker (features: Point) will still call its data from the server.

is there a way or example that I can read that matches my app plan?

MIT has not released a tutorial for the very complex Map components yet.    

Have you read the documentation http://ai2.appinventor.mit.edu/reference/components/maps.html  ?

You should be able to do some of what you want to do using the OpenStreetMap tiles the Map component uses.

What have you tried so far?

There are numerous discussions about using the Map component in the forum and there are some examples.   Search the Forum for   MIT Map    and Map component  and you will find some example block code and a few aia files.
