Several ways of setting built-in APP

Code modification method

App folders can be added under the vendor directory

Not uninstallable

Refer to vendor/firefly/fireflyapi

• Contents in Android.mk

  LOCAL_PATH := $(call my-dir)
  include $(CLEAR_VARS)
  LOCAL_MODULE := firefly_sdkapi_demo
  LOCAL_MODULE_CLASS := APPS
  LOCAL_MODULE_TAGS := optional
  LOCAL_BUILT_MODULE_STEM := package.apk
  LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
  #LOCAL_PRIVILEGED_MODULE :=
  LOCAL_CERTIFICATE := platform
  #LOCAL_OVERRIDES_PACKAGES := 
  LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
  #LOCAL_REQUIRED_MODULES :=
  #LOCAL_PREBUILT_JNI_LIBS :=
  include $(BUILD_PREBUILT)

  • LOCAL_CERTIFICATE := platform Meaning: APK signature uses system signature
  • LOCAL_PRIVILEGED_MODULE If not set or set to false, the installation location is /system/app

• Contents in fireflyapi.mk

  PRODUCT_PACKAGES += \
     	firefly_sdkapi_demo 
  
  PRODUCT_COPY_FILES += \
         vendor/firefly/fireflyapi/fireflyapi:system/bin/fireflyapi \

• copy apk to device/rockchip/CPU_TYPE/PRODUCT_TYPE/preinstall_del
• build android
