Popular questions for this item
Does it supports offline usage?
Yes, it does. All you need to do is connect the app for the first time, when the phone loses connection, it retrieves the data stored in your app and display it to the user. It doesnt need to connect to the internet all the time.
If it supports offline, does the images too in thumbnails and galleries?
Yes, the image were cached, which means it is not physically stored in the apps documents directory rather it is stored temporarily.
I updated the XML/ JSON but it has a problem and will not show appropriately in the app. What should I do?
You should validate your XML/JSON file, a lot of validators over the internet, search which one the best for you. Proper format are stored together when you purchased the app.
In what extent you provide support?
As what we have said, we will support you until the end of the world, like a bug fixes, installation error, or maybe a major update if it is intended to. Any strong modification of the code, like a heavy customization, I suggest contact us for freelance work. It is our pleasure to help you.
