New version of Average Data Usage Widget (V 2.0)

A friend asked: "can you somehow show the usage on each day?" and then this happened.

It turns out that it is in fact possible to check the usage on an arbitrary interval, and with a bit of calendar magic you can display a list with the usage on each day.
This list is a bit raw, and not sure if very useful, but as usual, it was fun.

However the main reason for the update wasn't this (in fact I started that after the previous version but never finished it).
The new feature is the ability to configure an 'accumulate' data, where the unused data on a period/month is accumulated for the next period. It requires manual setting for the first time, and probably tweaking it each period (it is automatically updated, but android isn't very precise with the data usage). It will only need to be set once each month, so nothing big.

Hope it is useful! (it is for me, :P ) And also I set the version to 2.0, because now there is a main screen instead of the main+settings unique activity from before.

Current status: stable


V 2.0
- History activity: you can view the usage on each day of the period. Button from the main widget opens this.
- Accumulate option. Enable this if your provider saves the unused data for the next period.
- New main screen, separated options to secondary one.
- Small tweaks for the size and view of the widgets.
