I am decided to create an application that can pass the coordinates data stored in Spatialite data to the Google Map for Android for marker display.
Use spatialite-android in your app.
You can download binaries here and add *.so files in your app's lib folder.
How to connect, work with spatial data, you can guide yourself by exemples from here

I am developing a photo vault using Flutter. I need to list all the images in the mobile storage, and when the user picks one or more images. I need to move that image(s) into App Private. So that no other app can see it. So for moving the file, I need the location/path of the picked image(s). which no plugin on earth is providing.
Below is the list of plugins I tried. Each one of them provides the path of the image copied to the app private directory. No the original one
file_picker 2.1.6
image_picker 0.6.7+22
multi_image_picker 4.7.15
It would be a big help if you could suggestion some solution for it.
Thank You
Is it possible to download a MapBox map as a file on a computer rather than mobile. Then load that file into iOS and Android MapBox SDK?
The idea is to have many phones who will never have internet access and just to load the map off internal storage.
Talked to MapBox reps and it looks like this isn't possible without being on the MapBox Enterprise plan. There is not functionality in the public API for this to work.
I'm developing an Android application and I need to implement offline maps. For this I use OpenStreetMap, or rather osmdroid.
I need to implement the loading of maps when executing the program based on where the user is located. My question is, is it possible to load maps when I run the application and how do I do this?
Yes.
Off device, using MOBAC, you can follow this guide: https://github.com/osmdroid/osmdroid/wiki/Offline-Map-Tiles#mobile-atlas-creator-mobac
On device, using osmdroid, you can use the cache manager:
https://github.com/osmdroid/osmdroid/wiki/Offline-Map-Tiles#use-osmdroids-cache-manager-on-device---version-52
There are several links to examples and source code, such as the one in the osmdroid sample app, which is on the play store or available for download on github.

I need to develop a mobile application that communicating with rest service. I think that using of intel xdk cross platform may be appopriate for that. I got some informations via internet investigation about the platform. Then i learnt that local db usage is possible by IndexedDb. But im confused with size limitation of persistent db file. So application may need to db file to use during offline bigger than 10mb. Is it a problem. By the way, offline db contains products with pictures. Im curious about that Is it possible to persist a field with only filepath referenced to mobile storage instead of byte of file? For example is it possible to save picture file which came from service to somewhere belonged to mobile's storage? Finally, can i deploy my program with initial db? Thx, brgds
There are many options for local storage for your app. It is important to understand that an XDK app is a Cordova app. The name XDK refers to the tool, not the runtime environment. Your XDK tool creates Cordova apps.
Try searching for something like "phonegap cordova local storage solutions" for a list of the options available to you when you create a Cordova app.
BTW -- PhoneGap apps are also Cordova apps. :)
I want to make an application for iphone, ipad, and android using HTML 5.
This application will create a SQLite database or place a prefilled SQLite database file when it is installed on ipad/iphone/android.
I want to keep it in a folder where my application is installed.
eg
ApplicationName- Files (where I have all the files for the application)
ApplicationName- DB (where I will have my sqllite database)
I want to connect to SQLiteDB using javascript.
Can I access the db at a particular location from my application using Javascript or jquery.
Can you suggest me some way I can get into this.
I would advise you to look at Apache Cordova (old Phonegap) to see how they handle things or use they own solution for this kind of thing.
But if you really want to walk alone, you need to build 2 sets of frameworks to call native code, or use web sql database(inactive) or something similar.
