我需要通过添加一些自定义库来更改“设置”应用,但我遇到配置问题。当我尝试调用System.loadLibrary(" mylibrary")时,我得到libraryPath = / data / app-lib / com.settings-1:find库返回null。我知道应用程序将查看特定库的/ data / app-lib / ..文件夹,但我的库位于system / lib
我知道我的.mk文件不行,但我不知道我错过了什么,请看看它们。
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_JAVA_LIBRARIES := bouncycastle telephony-common
LOCAL_STATIC_JAVA_LIBRARIES := guava android-support-v4 jsr305
ifdef DOLBY_DAP
LOCAL_JAVA_LIBRARIES += framework_ext
else
LOCAL_STATIC_JAVA_LIBRARIES += libsds
endif #DOLBY_DAP
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_PACKAGE_NAME := Settings
LOCAL_CERTIFICATE := platform
# If this is an unbundled build (to install seprately) then include
# the libraries in the APK, otherwise just put them in /system/lib and
# leave them out of the APK
ifneq (,$(TARGET_BUILD_APPS))
LOCAL_JNI_SHARED_LIBRARIES := efuse_tool
else
LOCAL_REQUIRED_MODULES := efuse_tool
endif
LOCAL_PROGUARD_FLAG_FILES := proguard.flags
include $(BUILD_PACKAGE)
include $(call all-makefiles-under, jni)
ifndef DOLBY_DAP
include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := libsds:ds.jar
include $(BUILD_MULTI_PREBUILT)
endif
# Use the folloing include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))
和jni文件夹中的.mk文件
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# Here we give our module name and source file(s)
LOCAL_SRC_FILES := efuse_tool.c
LOCAL_MODULE := efuse_tool
include $(BUILD_SHARED_LIBRARY)
答案 0 :(得分:3)
我意识到我必须添加前缀" lib"到我的库,所以它将从system / lib位置调用。所以看起来应该是这样的
ifneq (,$(TARGET_BUILD_APPS))
LOCAL_JNI_SHARED_LIBRARIES := libefuse_tool
else
LOCAL_REQUIRED_MODULES := libefuse_tool
endif
LOCAL_MODULE := libefuse_tool
我也可以删除LOCAL_JNI_SHARED_LIBRARIES:= libefuse_tool,因为它永远不会被使用。
