This should be reverted once #698 is fixed. If execution has gotten this
far into InstallManagerService, there should always be App and Apk
instances. That is enforced when Intents are received by this Service.
This was saying that the Privileged Extension is enabled but not properly
configured. This is because the preference logic changed to default to on
unless the user explicitly disabled it. So using the Privileged
Extension based on whether its installed and whether the user has disabled
it.

I guess APKs could disappear, or perhaps not be readable.

Here's the stacktrace:
java.io.FileNotFoundException:

This totally changed the logic of the "Use Privileged Extension" preference
making it based on whether the Privileged Extension is installed and usable
rather than storing the user's selection. This code now only stores when
the user manually disables using the Privileged Extension even when it is
installed.

The root install method that is available via the "Expert" preferences does
not work on newer than android-19. So when that's the case, this hides
that item from the preferences screen entirely.
I'm not 100% sure on how the `@TargetApi` and `VerifyError` work
together. However it is something along the lines of:
* Class loader needs `CleanCacheService`.
* At this point, it loads the bytecode for that class and verifies
that it all makes sense.
* The bytecode within the method targeted at API 21 is not understood
by earlier APIs, because the entire `Os` class was introduced in 21.
* By putting it into a different class, that class is only loaded
at runtime on devices with API of 21 or higher.
Previously, `@TargetApi` + the relevant guard condition to check
the build version at runtime suffices to prevent this. However it seems
that if the entire class does not even exist on earlier APIs, then it
is no longer good enough.
At time of writing (and for some time before), fdroidserver has forced
a description of "No description available" for apps which don't have
descriptions at all:
* https://gitlab.com/fdroid/fdroidserver/blob/0.6.0/fdroidserver/metadata.py#L876
However, if the description is not set for whatever reason, it should not
crash the client.
The icon files are downloaded for each version of the app. Over time, old
versions will pile up. This cleans out the ones that have not been used in
over a year.
On < android-21, this will delete icons that were downloaded over a year
ago even if they are still in use because it is only possible to check
mtime, not atime.
If CleanCacheService runs while an APK is being installed, it should not
delete the APK that is in the process of being installed. This does that
by only deleting those files if they are older than an hour. Same goes for
the index files.
#738
It was passing the wrong time value in the recursion, which made for a
really old "olderThan" time. This also then flipped the logic on the
next round through the recursion, causing files to be deleted even if
"Keep Cache Time" was set to "Forever".
closes#719closes#736
Before, CleanCacheService was only scheduled at app start for once a day.
If the user selects a time less than a day, then CleanCacheService should
run more frequently.
closes#719
In android-21, they exposed the formerly internal method for getting stat
structs of files. From that, we can get the last access time, which is a
much better way to determine which files to delete rather than last
modified time.
closes#644
By catching the exception here and returning null, the problem is then
passed on further down the line where it is harder to debug. The hash is
required wherever this method is called, so this should fail immediately.
#699
AS picked up that the statement is always false, so the body of the if is
never executed. This is indeed the case, because the constructor assigns
the object which is being checked for null.
The code only existed so that it could be used in a test. Subsequently,
a further test was written to test this code (used by the first test).
Since none of the code is actually used in the app, it has been removed.
See #511 for details. This is in prepration for having an even more normalized
`fdroid_package` table. That table will be the authoritative reference of what
"packages" are known about in the client. The "app" table (now thought of as "app metadata") will
be specific to each repository which provides different metadata about that app.
