From 0470ceea381775b09eee931858c3320be88cc637 Mon Sep 17 00:00:00 2001 From: Tao Bao Date: Wed, 2 Aug 2017 17:11:04 -0700 Subject: Allow customizing WearRecoveryUI via Makefile variables. With the following Makefile variables, we can reduce the work of writing (copy/pasting) device-specific WearRecoveryUI classes. The list of Makefile variables (the ones useful for Wear devices): - TARGET_RECOVERY_UI_MARGIN_HEIGHT (default: 0) - TARGET_RECOVERY_UI_MARGIN_WIDTH (default: 0) Specify the margin space that we don't want to display texts. They replace the former outer_width and outer_height. - TARGET_RECOVERY_UI_TOUCH_LOW_THRESHOLD (default: 50) - TARGET_RECOVERY_UI_TOUCH_HIGH_THRESHOLD (default: 90) Specify the sensitivity of recognizing a swipe. Devices give absolute positions, so for some devices we need to adjust the thresholds. - TARGET_RECOVERY_UI_PROGRESS_BAR_BASELINE Specify the progress bar vertical position, which should be adjusted to the actual height of a device. It replaces the former progress_bar_y. - TARGET_RECOVERY_UI_ANIMATION_FPS (default: 30) Specify the animation FPS if using device-specific animation images. It replaces the former animation_fps. Devices can specify "TARGET_RECOVERY_UI_LIB := librecovery_ui_wear", with optionally defined Makefile vars above, in BoardConfig.mk to customize their WearRecoveryUI. Also remove the obsolete wear_touch.{cpp,h}, which has been merged into ui.cpp in commit 5f8dd9951d986b65d98d6a9ea38003427e9e46df. Bug: 64307776 Test: Change the device BoardConfig.mk and test recovery image.
