Please tell me what parts of this script I need to change to use it with my app. Also, does it have to be called todo_main?

thanks

Hi Dave.

Unfortunately your question is not clear enough.

Please provide more details:

What do you want to implement?

What have you tried?

What is not working?

etc.

Hi Yurii, I am still trying to get an offline sqlite db to launch and provide data to my application. I have gotten to the point I can see my tables in the Dev Console of the browser, now need it to identify it is offline, and create the db locally on a mobile device.

When testing on my mobile device, I can see the db list when online, but when I back out and exit the app, turn off the wireless connection, and restart the app, I click on the button to take me to my list and I see the little wheel turn for a split second, then nothing.

Hello Dave!

Please let's continue within one post https://getsatisfaction.com/apperyio/...
