20250416在荣品的PRO-RK3566开发板的Android13下编译native C的应用程序的步骤
2025/4/16 19:05

缘起：2012年？前后，做freescale的i.MX6Q的Android4.0.4/Andorid4.2.2/Android4.4.2？的时候。
当年为了使用最高的效率来取摄像头的每一帧图像，不能使用APK/JAVA。
最后有人提高了使用native C的应用程序。

现在需要RK3566在Android13下将UART6接收到的的marvlink数据通过UART9/UART3转发出去。115200bps N 8 1。

荣品建议我们参考：Z:\hailuo_temp\Android13.0\external\sc16is752\Android.mk

可以参考这个安卓13 平台 添加对应测试的c 文件的

应用程序 弄好之后 直接使用 mm编译吗？
全局编译就行

已经全局编译了。现在 想单独 编译这个应用程序！
我这边都是全局编译生成的，没有单独编译的方式提供给你哈
