Android開發之自定義庫和第三方庫混合程式設計腳本編寫

一、AndroidStudio 混合程式設計流程

1.1 設定支援的arm的類型

在build.gradle中設定arm的類型,如果不設定也就是忽略此步驟，預設支援所有的類型，運作項目後，系統根據自身的arm類型，自動選擇加載

......

android {
	defaultConfig {
   ....
        ndk {
            // Specifies the ABI configurations of your native
            // libraries Gradle should build and package with your APK.
            abiFilters 'armeabi-v7a','arm64-v8a'
        }
  ......
}

......

           

1.2 編譯自定義庫和第三方庫

1.2.1 編譯第三方庫

CMakeList.txt:

#1.設定第三方庫頭檔案所在位置  
#此目錄為CMakeList.txt父目錄下的thirdLibrary目錄
include_directories(${PROJECT_SOURCE_DIR}/thirdLibrary/include)

add_library(thirdLibrary
        SHARED
        IMPORTED)

# 設定第三方動态庫屬性（存儲位置） 
#此目錄為CMakeList.txt父目錄下的opus/libs目錄
set_target_properties(thirdLibrary
        PROPERTIES IMPORTED_LOCATION
       ${PROJECT_SOURCE_DIR}/thirdLibrary/libs/${ANDROID_ABI}/libthirdLibrary.so)`
           

1.2.2 在自定義庫中加載第三方庫

add_library( # Sets the name of the library.
        selfLibrary

        # Sets the library as a shared library.
        SHARED

        # Provides a relative path to your source file(s).
        selfLibraryFunction.cpp
 }

find_library( # Sets the name of the path variable.
        log-lib

        # Specifies the name of the NDK library that
        # you want CMake to locate.
        log )

# 連結第三方庫
target_link_libraries( # Specifies the target library.
        selfLibrary

        thirdLibrary
        # Links the target library to the log library
        # included in the NDK.
        ${log-lib} )
           

二、Eclipse 混合程式設計流程

2.1 編譯自定義庫和第三方庫

2.1.1 編譯第三方庫

Android.mk

#include $(CLEAR_VARS)

#LOCAL_MODULE := thirdLibrary

#LOCAL_SRC_FILES := ./kwPrivateData/libs/armeabi-v7a/libthirdLibrary.so

#include $(PREBUILT_SHARED_LIBRARY)
           

2.1.2 在自定義庫中加載第三方庫

include $(CLEAR_VARS)

LOCAL_SHARED_LIBRARIES := thirdLibrary
LOCAL_MODULE    := selfLibrary

LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \

LOCAL_SRC_FILES := \
selfLibraryFunction.cpp

LOCAL_LDLIBS += -llog

include $(BUILD_SHARED_LIBRARY)
