      • Parameter Description: https://developer.android.google.cn/ndk/guides/cmake

        • ANDROID_ABI: The following values can be taken: Goal ABI. If the target ABI is not specified, CMake uses armeabi-v7a by default. Valid ABI are:
          • armeabi：CPU with software floating point arithmetic based on ARMv5TE
          • armeabi-v7a：ARMv7-based device with hardware FPU instructions (VFP v3 D16)
          • armeabi-v7a with NEON：Same as armeabi-v7a, but with NEON floating point instructions enabled. This is equivalent to setting -DANDROID_ABI=armeabi-v7a and -DANDROID_ARM_NEON=ON.
          • arm64-v8a：ARMv8 AArch64 Instruction Set
          • x86：IA-32 Instruction Set
          • x86_64 - x86-64 Instruction Set
        • ANDROID_NDK The path of installed ndk in host
        • ANDROID_PLATFORM: For a full list of platform names and corresponding Android system images, see the [Android NDK Native API] (https://developer.android.google.com/ndk/guides/stable_apis.html)
        • ANDROID_ARM_MODE
        • ANDROID_ARM_NEON
        • ANDROID_STL: Specifies the STL that CMake should use.
          • c++_shared: The shared library variant of libc++.
          • c++_static: The static library variant of libc++.
          • none: No C++ standard library support.
          • system: The system STL

      • Install apk to devices

         adb install android-build-debug.apk 
        

      • Qt6 and later

        cd build ${Qt6_DIR}/bin/qt-cmake .. -DCMAKE_BUILD_TYPE=Release cmake --build . --config Release

        Or:

        cmake .. -DCMAKE_BUILD_TYPE=Release
        -DCMAKE_INSTALL_PREFIX=pwd/android-build
        -DCMAKE_TOOLCHAIN_FILE=$Qt6_DIR/lib/cmake/Qt6/qt.toolchain.cmake cmake --build . --config Release

  • Use qmake. (Deprecated, please use CMake for new programs)

    cd build
    qmake ../RabbitCommon.pro
    make install
    

    • Parameter
      • BUILD_DOCS: build doxygen documents
      • BUILD_ABOUT=OFF: Off build about
      • BUILD_UPDATE=OFF: Off build updater
      • BUILD_ADMINAUTHORISER＝OFF: Off admin authoriser

• Compilation notes: Use Qtcreate compile for android in windows

  • qmake. It may appear that the dependent library could not be found. (Deprecated, please use CMake for new programs)

    Don't find D:\Source\build-RabbitCommon-Android_for_armeabi_v7a_Clang_Qt_5_12_4_for_Android_ARMv7-Debug\bin\libRabbitCommon.so move libRabbitCommon.so ..\bin\libRabbitCommon.so process_begin: CreateProcess(NULL, move libRabbitCommon.so ..\bin\libRabbitCommon.so, ...) failed. make (e=2): The system can not find the file specified。 make[1]: [..\bin\libRabbitCommon.so] Error 2 (ignored)

  The reason is that the make program under windows cannot convert the \ in the path. Solution: Use a make program that recognizes the \ in the path, for example: mingw32-make.exe.

  • cmake

    • Set Generator to "Unix Makefiles"
    • Set CMAKE_MAKE_PROGRAM to ${ANDROID_NDK}/prebuilt/windows-x86_64/bin/make.exe

• Install notes:

  • windows
    If you build app. Qt does not provide openssl dynamic library for copyright reasons, so you must copy the dynamic library of openssl to the installation directory.

    • If it is 32, you can find the dynamic library of openssl (libeay32.dll, ssleay32.dll) in the Qt installer Tools\QtCreator\bin directory.
    • If it is 64-bit, you will need to download the binary installation package for openssl yourself.

  • linux

  sudo apt-get install libssl1.1

• Install Authors、 License、 ChangeLog files.
  File name naming rules:
  Authors.md、License.md、ChangeLog.md is the default file.
  The local file naming rule is to add the local name after the default file name.
  For example: Chinese file:
  Authors_zh_CN.md、License_zh_CN.md、ChangeLog_zh_CN.md

    SET(OTHER_FILES
        ${CMAKE_SOURCE_DIR}/License.md

adminauthoriser.h

• Internal implementation

  QString szCmd = "mkdir";
  QStringList paras;
  paras << "-p" << "/opt/RabbitCommonAdminAuthoriseTest";
  qDebug() << "RabbitCommon::AdminAuthoriser::Instance()->execute(szCmd, paras):"
           << RabbitCommon::AdminAuthoriser::Instance()->execute(szCmd, paras);
  

• Public interface:

  RabbitCommon::CTools::executeByRoot("regedit", QStringList());
  

The program starts automatically
