What

This Pull Request adds to a new activity to the repository which can be used to select a verification method when pairing over Bluetooth. The choice is either a visual pattern or a tab pattern. When selecting a verification method an activity for that method will be opened.

Why

This Pull Request is needed because we want to user to be able to select a verification method (currently visual patter or tab pattern).

How

You can change the target activity in the intent in the EntryActivity to be SelectVerificationMethodActivity. When you did that and you start the app, the new activity will open immediately.

Alternative implementation

None, we want the user to be able to choice a verification method and for that we kinda need a activity (a popup would be possible, but very ugly/unintuitive imho).

Notes

There are a few important things to not here:

• I did not yet pay any attention to the layout, if you want that in this PR feel free to give suggestions on the layout 😄
• The "Remember my choice" checkbox has not been implemented yet and I don't plan on doing that in this PR since we have not yet implemented settings.
• The rhythm button does not yet go to the rhythm activity, as it is not yet available on this branch/develop...
