OMAPI是啥?看看谷歌的解释:
 
 说了一大堆懂的人不需要看,不懂的还是看不懂,我就是后者
 总之说人话就是,像SIM卡,NFC这类模块需要用到这个东西,那么接着往下看
 
 上层APP想要使用这个OMAPI供应商稳定版服务功能,会调用到SecureElement这个APP的接口
 以下为SecureElement的代码路径:
 
 但是安卓13版本上SecureElement默认是不开启OMAPI供应商稳定版服务功能,需要在packages/apps/SecureElement/res/values/config.xml这个路径下将“secure_element_vintf_enabled” 这个属性修改为"true"。咋们看看secure_element_vintf_enabled 是哪段代码中被加载
 
 看看VSTABLE_SECURE_ELEMENT_SERVICE 这个变量的值是android.se.omapi.ISecureElementService/default
 可以看到当secure_element_vintf_enabled为true的时候,android.se.omapi.ISecureElementService/default 这个hal层服务才被加载。
那么将secure_element_vintf_enabled 属性修改为true后,编译刷机。
 开机完成后进入Launcher,弹出SecureElement的报错框,随后系统进入recovery模式,使用adb logcat > F:/log/1111.log抓取日志,看看为什么报错,报错日志如下:

根据日志可以看到导致SecureElement报错,系统也进入recovery模式的罪魁祸首就是hal层中OMAPI相关的服务并没有被加载
hwservicemanager: getTransport: Cannot find entry android.hardware.secure_element@1.0::ISecureElement/eSE1 in either framework or device VINTF manifest..    // eSE1相关hal层服务未被加载 
hwservicemanager: getTransport: Cannot find entry android.hardware.secure_element@1.2::ISecureElement/SIM1 in either framework or device VINTF manifest.     // SIM1相关hal层服务未被加载
像这类问题,一般是在device.mk文件中配置编译规则,编译规则一般是判断宏定义的值来决定hal层的服务是否被编译
先记录到这,后续更新
