Native iPhone apps can access geolocation data in the background. Can HTML5? Based on this stack overflow posting, I suspect not.
Mark and I worked together today, and the aim was to get the camera working in the app, using code on the server.
We also decided to host a local version of the server on my Mac, to streamline testing. It was getting a bit cumbersome to use Filezilla to transfer changes to the server code back to the server every time we wanted to test a bug. This was pretty tricky to get working with phone gap, so here’s a summary of how we did it:
- We downloaded MAMP (Macintosh, Apache, PHP and MySQL packaged together).
- We then needed to transfer both the server web pages and the server database to my Mac, and then point the local copy of the web pages and the phone gap shell to the local host.
- Go to the server’s phpMyAdmin and export the relevant database. We found that gzipping it did not work, but zipping it did.
- On the MAMP local host homepage (localhost:8888) there is a link to phpMyAdmin, where you can import the above file.
- MAMP looks for the webpages at Applications/MAMP/htdocs by default. We chose to put all our local copy of the server webpages there (though in retrospect I should probably have put them in a subdirectory), and then add a new project in Eclipse using existing files in that directory (though the workspace remains elsewhere).
- Note that files that start with a dot, like .htaccess, do not display by default in the Finder, so when copying files around, they can get left behind. I needed to recopy .htaccess into the htdocs directory.
- In our local webpages, we changed the mysql_connect statement to use localhost:8889, with user root and password root. Obviously we will not put this change on the server.
- To run this on a physical device (whether it’s a phone gap app or a regular objective-c app), we cannot refer to ‘localhost’ but the actual local IP address. We looked this up in the terminal (although it is also in the System Preferences -> Network, or you can search the Mac for Network Utilities – it is not the same as you find at whatismyip.com) and added it to the whitelist, and referred to it in the source code instead of racingtadpole.com. To complicate matters, this address has changed for me over time.
Voila! Dinner is ready, so I must end there.
