之前参考过许多添加工程的文章,发现都有一个问题,只能单独编译该工程,而且打包时无法自动打包到镜像。
本文说明一个办法,可以添加工程在make的时候自动打包到镜像。
一、添加工程源码
为了简单尝试,直接复制system/core/中的reboot工程目录,命名为hello目录,里面的源码也命名为hello.c。Android.bp和hello.c修改如下:
- // Copyright 2013 The Android Open Source Project
-
- package {
- default_applicable_licenses: ["Android-Apache-2.0"],
- }
-
- cc_binary {
- name: "hello",
- srcs: ["hello.c"],
- shared_libs: [],
- cflags: ["-Werror"],
- recovery_available: true,
- }

-
- int main(int argc, char* argv[]) {
- printf("hell %d %s\n", argc, argv[0]);
- return 0;
- }
二、以上步骤都可以在其他文章了解到,以下是最关键的一步,添加工程到buid/target/product/base_system.mk中,在该配置文件中加上一句:
PRODUCT_PACKAGES += hello
三、编译make -j32
四、测试:
烧录镜像到目标开发板
用adb shell连接上
用ls /system/bin查看是否有hello文件存在
用hello命令尝试是否可以执行
五、祝好运
