VBCS - startup question

Content

My client is evaluating VBCS to develop the mobile applications and asked following queries:

• How to implement the following in VBCS:
  • the Session Management: any example
  • List view Customization
  • Image uploading and gallery images upload to server with API parameter
  • Something similar to “Page trigger fire”
  • Google console API usage like (Google Map, Push notification and etc..)
  • Third party integrations
  • Business logic to parse the data received as API response.

Apart from this, how to include “user notifications” and “broadcast receiver settings”. Slowness and hanging is very often.

Last but not the least, how to save the progress of the working project? Currently contents of the project are not saved.
