Android 5.x OTA Update官方文檔(七、構建裝置),androidota

我們通過調用recovery_ui.cpp中make_device()函數來建立一個Device的執行個體,如下:

class TardisDevice : public Device {   // ... all the above methods ...};Device* make_device() {    return new TardisDevice();}

編譯recovery_ui.cpp

再通過前一篇對recovery_ui.cpp的介紹我們來介紹一下如何為recovery_ui.cpp建立一個靜態庫。

Device/yoyodyne/tardis/recovery/Android.mk

LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE_TAGS := engLOCAL_C_INCLUDES += bootable/recoveryLOCAL_SRC_FILES := recovery_ui.cpp# should match TARGET_RECOVERY_UI_LIB set in BoardConfig.mkLOCAL_MODULE := librecovery_ui_tardisinclude $(BUILD_STATIC_LIBRARY)

然後我們在BoardConfig.mk檔案中指定靜態庫中TARGET_RECOVERY_UI_LIB的值,如下:

device/yoyodyne/tardis/BoardConfig.mk [...]# device-specific extensions to the recovery UITARGET_RECOVERY_UI_LIB := librecovery_ui_tardis
