Changes include
Add new remote call in default container service to determine
install location.
Rename INSTALL_ON_SDCARD
Remove recommentAppInstall method
Add some additional flags used in remote stubs.
Move check for protected apps prior to copy.
Unit tests
DefaultContainerService first parses the file uri(if content uri is specified
it returns a default install internal only value) and returns
a recommended location. Based on which the temporary id is determined
either a file name or a container id and the file is copied there.
This is then later renamed during install.
Todo's light weight parsing of package when determining location since we
just need the install location attribute only when finding out
recomended location. This will also enable to move the check for
updated system apps(cannot be on sdcard) prior to copying.
This implements the spec for external storage organization, and
properly reflects how the media scanner organizes the files it finds.
Also includes package manager support for removing app private
files from external storage when the application is uninstalled.
For the new APIs and paths, the main place to look is Environment
and Context.
Add new remote interface to do temporary copies. The new
remote stub handling is done on mHandler thread and doesn't need locking
for now.
Add new InstallArgs class and subclasses to isolate cases for installation.
Move resource deletion for failed installs/upgrades to later on in installation
cycle.
Fix code path for forward locked apps when using scanPackageLI
TODO's
Fix installation paths to completely use InstallArgs based design later on.
Get rid of using flags in various install/uninstall code paths.
Ideally InstallArgs should be created using these flags and used in the
rest of the code.
Function renames.
Revisit mount api's.
