@oxtoacart I marked this PR as draft because I'm waiting for these PRs to get merged before I pulled those changes into this PR:

• [4656] Add the TTLS param to bandwidth updates flashlight#969
• https://github.com/getlantern/android-sdk/pull/5

I also need to update the translations as well.

Doesn't this still need to update bandwidthUpdate in LanternSessionManager?

Unfortunately in its current state lantern mobile doesn't build.

I tested this on my Samsung Galaxy S10e running Android 9. The notification showed up okay, but there's some issues with the display on the main screen.

1. When I have partial data usage, the progress bar is complete blank, but once I hit 100% it's completely full. Looks like maybe the in-between values aren't being rendered right.
2. On the data usage tab, the progress bar is empty even when I'm at 100% data usage
3. The formatting of the text next to the Upgrade button isn't great. Putting the "Resets At" message on a separate line would help

• I have updated the text formatting to put Reset At into a separate line.
• I also updated the Upgrade to Pro for unlimited data... text to have exactly the same text style with the above (it previously a little bit smaller, and not fully left aligned, which doesn't look really good).

For testing different bandwidth updates, I added this block of code, so I can change the values to whatever I want.
Just to confirm, the percent is the used percent, not remaining percent right?

As far as I'm testing, the app is showing the progress correctly. I couldn't reproduce the issue. Btw, I don't think this PR introduces those issues, so if we want to push out a new build, I think we can create separate tickets to address the issues and merge this PR.

I found a few issues with this. They're addressed in #21. With that PR (and removing convertTTSToDateTimeString from mobilesdk), this PR is good to merge.
