| /** |
| * Handles writing and reading PhoneAccountHandle registration entries. This is a simple verbatim |
| * delegate for all the account handling methods on {@link android.telecom.TelecomManager} as |
| * implemented in {@link TelecomServiceImpl}, with the notable exception that |
| * {@link TelecomServiceImpl} is responsible for security checking to make sure that the caller has |
| * proper authority over the {@code ComponentName}s they are declaring in their |
| * {@code PhoneAccountHandle}s. |
| * |
| * |
| * -- About Users and Phone Accounts -- |
| * |
| * We store all phone accounts for all users in a single place, which means that there are three |
| * users that we have to deal with in code: |
| * 1) The Android User that is currently active on the device. |
| * 2) The user which owns/registers the phone account. |
| * 3) The user running the app that is requesting the phone account information. |
| * |
| * For example, I have a device with 2 users, primary (A) and secondary (B), and the secondary user |
| * has a work profile running as another user (B2). Lets say that user B opens the phone settings |
| * (not currently supported, but theoretically speaking), and phone settings queries for a phone |
| * account list. Lets also say that an app running in the work profile has registered a phone |
| * account. This means that: |
| * |
| * Since phone settings always runs as the primary user, We have the following situation: |
| * User A (settings) is requesting a list of phone accounts while the active user is User B, and |
| * that list contains a phone account for profile User B2. |
| * |
| * In practice, (2) is stored with the phone account handle and is part of the handle's ID. (1) is |
| * saved in {@link #mCurrentUserHandle} and (3) we get from Binder.getCallingUser(). We check these |
| * users for visibility before returning any phone accounts. |
