* Add ability to show "installing security update"Tianjie Xu2016-04-291-1/+14
| | | | | | | | | | | Add a new command "--security" to boot commands. If this command is observed as part of BCB, choose a different background text picture for installing stage in recovery UI. As a result, users will see "installing security update" instead of "installing system update" when applying a security update package.

* Go back to the old ear-wiggling Android animation.Elliott Hughes2016-04-211-1/+0
| | | | | | | | | | | | | But keep the new code so we can easily test new animations when we have them. This change includes tbao's de-interlace script, plus a one-liner that's necessary to play the animation at the correct speed when there's no progress bar showing. (This was always a bug, it's just way more noticeable when your animation only has 7 frames.) Bug: http://b/28316654 Bug: http://b/26548285 Change-Id: I32c601c352d6be235d1b44f14fca7e125defd77d
* Update the system update animation.Elliott Hughes2016-04-151-51/+92
| | | | | | | | | | | | | | | | | Switch to a Wear-like intro/loop system. We don't have an intro yet, but hopefully this will let Wear delete more code when they move to N. Unlike them, we don't hard-code the number of frames: we just look to see what we have available. We do hard-code the fps though. Also add a graphics test mode so you can see a demo of the UI components without having to actually apply an OTA. Also fix a bug where default locale is null rather than en-US: it's more useful to show _some_ text if we don't have a locale (which should only be during development anyway).

* recovery: Remove SetColor, and other refactoring for WearUIPrashant Malani2016-03-121-18/+18
| | | | | | | | | | | | | | The only difference from SetColor in ScreenRecoveryUI is the that the LOG messages have slightly different colors. That's not enough to warrant a duplicate function. So this patch removes SetColor and uses the parent class version. This patch also moves the DrawTextLine* functions into ScreenRecoveryUI since they're mostly the same. It also moves char_width and char_height into the class instead of keeping them as static variables. Bug: 27407422 Change-Id: I30428c9433baab8410cf710a01c9b1c44c217bf1
* recovery: Remove duplicate variables and functionsPrashant Malani2016-03-111-2/+2
| | | | | | | | | | | | | | | | | The function that modifies rtl_locale exists only in the base class, and so the variable should not have a duplicate in the derived class, otherwise there may be incosistent values when it is read by the derived class (the thinking being that invoking the function will modify the base class version of the variable, and not the derived class version). Remove the updateMutex variable, and instead re-use the one in the base class. Also remove LoadBitmap from WearUI since it is identical to the one in ScreenRecoveryUI.

* Revert "recovery: More refactoring of WearUI"Prashant Malani2016-03-101-2/+2
| | | | | | | | | This reverts commit 1c7b2230d8aac9f064f68c48b6aa26aca000cc9d. This change can lead to the derived class indirectly (and incorrectly) calling some functions from the base class, which can lead to unpredictable behavior.

* res: Embed FPS into icon_installing.png.Tao Bao2015-12-161-4/+5
| | | | | | | | | | | | | | We allow vendor-specific icon installing image but have defined private animation_fps that can't be overridden. This CL changes the image generator to optionally embed FPS (otherwise use the default value of 20) into the generated image. For wear devices, they are using individual images instead of the interlaced one. Change the animation_fps from private to protected so that it can be customized.

* recovery: Remove redirect_stdio() when calling ShowFile().Tao Bao2015-09-101-1/+1
| | | | | | | | | When calling ScreenRecoveryUI::ShowFile(), the only thing that gets inadequately logged is the progress bar. Replace the call to ScreenRecoveryUI::Print() with ScreenRecoveryUI::PrintOnScreenOnly() for the progress bar, so we can avoid calling redirect_stdio().

* Log update outputs in orderTao Bao2015-06-031-10/+25
| | | | | | | | | | | | | | Although stdout and stderr are both redirected to log file with no buffering, we are seeing some outputs are mixed in random order. This is because ui_print commands from the updater are passed to the recovery binary via a pipe, which may interleave with other outputs that go to stderr directly. In recovery, adding ui::PrintOnScreenOnly() function to handle ui_print command, which skips printing to stdout. Meanwhile, updater prints the contents to stderr in addition to piping them to recovery. Change-Id: Idda93ea940d2e23a0276bb8ead4aa70a3cb97700

* Fix recovery image text rendering.Elliott Hughes2015-03-241-7/+3
| | | | | | | | | | | | | | Previously most devices would lose the character before a line wrap. The log's text rendering was starting at offset 4 but none of the arithmetic was taking this into account. It just happened to work on the Nexus 9's 1536-pixel wide display (1536/18=85.3) but not on a device such as the Nexus 5 (1080/18=60). The only active part of this change is the change from 4 to 0 in the gr_text call. The rest is just a few bits of trivial cleanup while I was working out what was going on.

We also remove the 'indeterminate' progress bar used when wiping data and/or cache.

* tweak recovery text imagesDoug Zongker2012-09-181-1/+2
| | | | | | | | Center and fix the extents for those locales that have multiple lines of text. Add Urdu as an RTL language. Bug: 7064142 Change-Id: I4c1aa1198be29cab01129dabf2c4a026b93719a6
* localization for recovery messagesDoug Zongker2012-09-181-6/+46
| | | | | | | | | Add images of text for all locales we support. Make the progress bar fill the correct way for RTL languages. (Flip the direction the spinner turns, too, just for good measure.) Bug: 7064142 Change-Id: I5dddb26e02ee5275c57c4dc4a03c6d68432ac7ba
* minor recovery fixesDoug Zongker2012-09-041-4/+7
| | | | | | | | | | | - protect against missing/malformed bitmaps: fail to display them but don't crash. - don't draw animation overlays until the overlay offset is computed. - logging cleanup Change-Id: Ieb1c155cfbb11e643000bdb5d1a57900c8757739
* change recovery images to android with spinnerDoug Zongker2012-08-231-4/+4
| | | | | | Also make writing the locale a bit more robust. Change-Id: I803dd0aa0b9d6661fad74ea13fb085682402323c
* add simple text to recovery UIDoug Zongker2012-08-231-15/+46
| | | | | | | | | | | | | | | - recovery takes a --locale argument, which will be passed by the main system - the locale is saved in cache, in case the --locale argument is missing (eg, when recovery is started from fastboot) - we include images that have prerendered text for many locales - we split the background states into four (installing update, erasing, no command, error) so that appropriate text can be shown.

* fix timed progress bars in recoveryDoug Zongker2012-04-261-4/+8
| | | | | | | They're completely broken and have been for months because this code makes no sense. Change-Id: Ibabcd3dbe5a004a45b341e4a5215aa3df77e1861
* move key processing to RecoveryUIDoug Zongker2011-11-041-214/+40
| | | | | | | | | Move the key for handling keys from ScreenRecoveryUI to RecoveryUI, so it can be used by devices without screens. Remove the UIParameters struct and replace it with some new member variables in ScreenRecoveryUI. Change-Id: I70094ecbc4acbf76ce44d5b5ec2036c36bdc3414
* C++ class for device-specific codeDoug Zongker2011-10-311-38/+67
| | | | | | | | | | Replace the device-specific functions with a class. Move some of the key handling (for log visibility toggling and rebooting) into the UI class. Fix up the key handling so there is less crosstalk between the immediate keys and the queued keys (an increasing annoyance on button-limited devices).

* refactor ui functions into a classDoug Zongker2011-10-311-0/+633
Move all the functions in ui.c to be members of a ScreenRecoveryUI class, which is a subclass of an abstract RecoveryUI class. Recovery then creates a global singleton instance of this class and then invoke the methods to drive the UI. We use this to allow substitution of a different RecoveryUI implementation for devices with radically different form factors (eg, that don't have a screen).
