Background

In android versions >= 13 requesting a permission requires an activity.
We need to request to disable the battery optimization and the permissions for notification.

Problem

We don't have an activity for the launcher when the start intent is sent and the service is started so we can't ask for battery optimization and notification permissions.

Feature

When sending a start intent and the notifications or battery optimization are not yet granted we should open an Introduction Activity where the user is guided through the process of giving the permissions.

This Activity should shortly explain what the fiskaltrust middleware is and why it needs these permissions.

When receiving a start intent and we're missing one of the permissions this activity should always be shown. But when we have the permissions this activity should never be shown.

Example flow

Hi, this is the fiskalturst.Middleware and we're used by your POS System to fulfill compliance regulations. etc. etc.

We need AAA that we can XXX.
Click to accept AAA permission

We need BBB that we can YYY.
Click to accept BBB permission

The buttons become greyed out once the permission is granted.

(Don't take this as gospel though. I'm sure we can think of a nice flow.)

Things to request in this activity

• Request POST_NOTIFICATION permission
• Request ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS
