android 编译单个模块

    技术2022-05-13  27

    android中的一个应用程序可以单独编译,编译后要重新生成system.img 在源码目录下执行

      . build/envsetup.sh (.后面有空格) 就多出一些命令:

      - croot: Changes directory to the top of the tree.

      - m: Makes from the top of the tree.

      - mm: Builds all of the modules in the current directory.

      - mmm: Builds all of the modules in the supplied directories.

      - cgrep: Greps on all local C/C++ files.

      - jgrep: Greps on all local Java files.

      - resgrep: Greps on all local res/*.xml files.

      - godir: Go to the directory containing a file.

    可以加—help查看用法 我们可以使用mmm来编译指定目录的模块,如编译联系人:

      # mmm packages/apps/Contacts/ or # make Contacts 编完之后生成两个文件:

      out/target/product/generic/data/app/ContactsTests.apk

      out/target/product/generic/system/app/ Contacts.apk 可以使用"make snod"重新生成system.img 再运行模拟器
