This addresses everything I could find. Unfortunately it does *not* fix this particular app. I am starting to think this is just an issue in the app. This change does fix a number of other problems I could repro, such as switching the compatibility mode of an IME. Also a few changes here and there to get rid of $#*&^!! debug logs. Change-Id: Ib15572eac9ec93b4b9966ddcbbc830ce9dec1317

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To avoid blowing past the Binder IPC limit, change the PackageManagerService to have a DB-like interaction where the client tells the service the last "row" that it read. The fact that we use a HashMap instead of a TreeMap makes this problematic. For now we're just making a new ArrayList for the keys and then sorting them for each call. This can make the API slower for callers of this, but it's probably greatly overshadowed by the cost of the data transfer itself. Bug: 4064282 Change-Id: Ia3a8cdaa94581ed9336f2e05694b8c8a5f757bce

The user must explicitly acknowledge the action on-device before it is allowed to proceed; this prevents any "invisible" pushes of content from the host to the device. Known issues: * The settings databases and wallpaper are saved/restored, but lots of other system state is not yet captured in the full backup. This means that for practical purposes this is usable for 3rd party apps at present but not for full-system cloning/imaging. Change-Id: I0c748b645845e7c9178e30bf142857861a64efd3

However, as currently implemented, BackupManager.requestRestore() [the public API in question] depends on private Backup Manager methods that *do* enforce that permission. The net result is that the method cannot be successfully used by third party applications: it will throw an exception if attempted. This CL restructures the permission checking involved. First, the underlying beginRestoreSession() operation can now be passed a 'null' transport name; if this is done, then the restore session is begun on whatever the currently-active transport is. Looking up the name of the active transport is one of the permission-guarded actions that was required with the initial implementation. Second, a package name can now be passed to beginRestoreSession(). If this is done, then the restore session can only be used to perform a single-package restore of that one application. The BACKUP permission is not required if the caller is tying the restore to its own package name. In combination, these changes permit BackupManager.requestRestore() to function without the calling app needing to hold any special permission. The no-permission case is intentionally quite narrow: the caller must hold the permission unless they both (a) pass 'null' for the transport name, thereby accepting whatever the currently active transport is, and (b) pass their own package name to restrict the restore session only to their own app. External bug http://code.google.com/p/android/issues/detail?id=10094 Internal bug 3197202 (Cherrypick from master to gingerbread) Change-Id: Ie20b0bd2420345ce6eda178f854680b558f6372a

The basic process consists of these interacting pieces: 1. The framework's BackupManagerService, which coordinates the collection of app data and routing to the destination. 2. A new framework-provided BackupAgent implementation called FullBackupAgent, which is instantiated in the target applications' processes in turn, and knows how to emit a datastream that contains all of the app's saved data files. 3. A new shell-level program called "bu" that is used to bridge from adb to the framework's Backup Manager. 4. adb itself, which now knows how to use 'bu' to kick off a backup operation and pull the resulting data stream to the desktop host. 5. A system-provided application that verifies with the user that an attempted backup/restore operation is in fact expected and to be allowed. The full agent implementation is not used during normal operation of the delta-based app-customized remote backup process. Instead it's used during user-confirmed *full* backup of applications and all their data to a local destination, e.g. via the adb connection. The output format is 'tar'. This makes it very easy for the end user to examine the resulting dataset, e.g. for purpose of extracting files for debug purposes; as well as making it easy to contemplate adding things like a direct gzip stage to the data pipeline during backup/restore. It also makes it convenient to construct and maintain synthetic backup datasets for testing purposes. Within the tar format, certain artificial conventions are used. All files are stored within top-level directories according to their semantic origin: apps/pkgname/a/ : Application .apk file itself apps/pkgname/obb/: The application's associated .obb containers apps/pkgname/f/ : The subtree rooted at the getFilesDir() location apps/pkgname/db/ : The subtree rooted at the getDatabasePath() parent apps/pkgname/sp/ : The subtree rooted at the getSharedPrefsFile() parent apps/pkgname/r/ : Files stored relative to the root of the app's file tree apps/pkgname/c/ : Reserved for the app's getCacheDir() tree; not stored. For each package, the first entry in the tar stream is a file called "_manifest", nominally rooted at apps/pkgname. This file contains some metadata about the package whose data is stored in the archive. The contents of shared storage can optionally be included in the tar stream. It is placed in the synthetic location: shared/... uid/gid are ignored; app uids are assigned at install time, and the app's data is handled from within its own execution environment, so will automatically have the app's correct uid. Forward-locked .apk files are never backed up. System-partition .apk files are not backed up unless they have been overridden by a post-factory upgrade, in which case the current .apk *is* backed up -- i.e. the .apk that matches the on-disk data. The manifest preceding each application's portion of the tar stream provides version numbers and signature blocks for version checking, as well as an indication of whether the restore logic should expect to install the .apk before extracting the data. System packages can designate their own full backup agents. This is to manage things like the settings provider which (a) cannot be shut down on the fly in order to do a clean snapshot of their file trees, and (b) manage data that is not only irrelevant but actively hostile to non-identical devices -- CDMA telephony settings would seriously mess up a GSM device if emplaced there blind, for example. When a full backup or restore is initiated from adb, the system will present a confirmation UI that the user must explicitly respond to within a short [~ 30 seconds] timeout. This is to avoid the possibility of malicious desktop-side software secretly grabbing a copy of all the user's data for nefarious purposes. (*) The backup is not strictly a full mirror. In particular, the settings database is not cloned; it is handled the same way that it is in cloud backup/restore. This is because some settings are actively destructive if cloned onto a different (or especially a different-model) device: telephony settings and AndroidID are good examples of this. (**) On the framework side it doesn't care that it's adb; it just sends the tar stream to a file descriptor. This can easily be retargeted around whatever transport we might decide to use in the future. KNOWN ISSUES: * the security UI is desperately ugly; no proper designs have yet been done for it * restore is not yet implemented * shared storage backup is not yet implemented * symlinks aren't yet handled, though some infrastructure for dealing with them has been put in place.

When running in compat mode, an application's windows are scaled up on the screen rather than being small with 1:1 pixels. Currently we scale the application to fill the entire screen, so don't use an even pixel scaling. Though this may have some negative impact on the appearance (it looks okay to me), it has a big benefit of allowing us to now treat these apps as normal full-screens apps and do the normal transition animations as you move in and out and around in them. This introduces fun stuff in the input system to take care of modifying pointer coordinates to account for the app window surface scaling. The input dispatcher is told about the scale that is being applied to each window and, when there is one, adjusts pointer events appropriately as they are being sent to the transport. Also modified is CompatibilityInfo, which has been greatly simplified to not be so insane and incomprehendible. It is now simple -- when constructed it determines if the given app is compatible with the current screen size and density, and that is that. There are new APIs on ActivityManagerService to put applications that we would traditionally consider compatible with larger screens in compatibility mode. This is the start of a facility to have a UI affordance for a user to switch apps in and out of compatibility. To test switching of modes, there is a new variation of the "am" command to do this: am screen-compat [on|off] [package] This mode switching has the fundamentals of restarting activities when it is changed, though the state still needs to be persisted and the overall mode switch cleaned up. For the few small apps I have tested, things mostly seem to be working well. I know of one problem with the text selection handles being drawn at the wrong position because at some point the window offset is being scaled incorrectly. There are probably other similar issues around the interaction between two windows because the different window coordinate spaces are done in a hacky way instead of being formally integrated into the window manager layout process.
