Do not allow manual backup/restore operations when removable storage is not available 2019-09-23 10:10:28 -03:00

When selecting USB storage, do a backup right away 
This is because USB drives are rarely plugged in,
so we should use every chance we get to do a backup.

Disable automatic backups when a removable USB flash drive is used 
as storage location.

The backup backoff time is not reliable for this as the system still
attempts to backup the magic @pm@ package without checking for the
backoff value.

Grant MANAGE_USB permission, so we can get USB serial numbers 
This is needed to reliably identify USB mass storage devices.
If someone has several identical thumb drives,
this prevents a backup from being performed when non-backup drives get attached.

Save the time of the last backup and only do automatic flash drive backups once a day 
This commit also turns SettingsManager into a class, so we can mock
and later also inject it.

Truncate files when writing to them explicitly 
For some reason this wasn't an issue on Pie,
but an instrumentation test caught the change in behavior on Q.

Upgrade to Android 10 (Q) 
If somebody wants the backup app to work on a lower Android version,
they need to maintain a branch for that which uses and targets the old API.

Use the MANAGE_DOCUMENTS permission to show possible storage locations 
This also auto-grants the needed Uri permission,
so the user does not need to go through the OS folder selection activity.

When restoring, ask for location first and then restore code 
This also checks if there's a backup at the chosen location
and requires the user to select another once,
if we can not find a backup.

Do not generate new 12-word code when restoring 
Also allow auto-completion when entering the 12-word code.
This makes testing and entering the code easier
and does not compromise security as the word list is public anyway.

Implement restoring of backup and show progress in UI 
Note that the progress view is not exact as the progress reporting of
AOSP seems to be buggy.

Return actually available RestoreSets 
Before, we were always returnign a dummy RestoreSet,
if one was actually available or not.

Now, we also include the device name.
Note that it is planned to store the actual device name
and other metadata in an encrypted file
so that the backup server will not learn it.

Show error notification when backup fails 
The implementation is rudimentary for now.
E.g. The notification is only shown when a device init fails
which seems to be triggered after the first failure.

Huge refactoring of backup transport 
* to get rid of global state
* to have a testable architecture
* to allow for authenticated encryption
* to have a backup format version
* to potentially allow for other storage plugins

6136f589c1 Android.mk: Download prebuilt apk instead of building it 
* With the upcoming changes, and the increasing number of external
  libraries being used, plus the usage of Kotlin, it's getting harder
  and harder to build this with the AOSP build system.
* It's best to leverage the existing gradle build system instead,
  and use the apk that builds.
* Add a script which downloads the apk matching the tag if a tag is
  checked out, otherwise downloads the latest.
