开发平台基本信息
芯片: MT8766
版本: Android 12
kernel: msm-4.19
问题描述
客户需要我们设备支持ESIM功能,5月份的时候在高通6125上面预研过ESIM功能,当时ESIM供应商是Links field,集成流程只是内置了ESIM厂商的apk,并且开启了feature以及默认给了一些权限,具体ESIM功能的实现都是在厂商的apk中,所以就没去深入研究ESIM功能。但是,由于Links field报价过高,所以这次又找了两家ESIM厂商,分别是鹏越与紫光;鹏越只把他们的ESIM芯片寄给了我们,然后让我们去找GMS实验室要LPA的相关资料,按照谷歌的标准流程操作,即可实现ESIM功能;而紫光则提供了一个他们的apk,并且要求给权限与feature,与之前的Links field类似。GMS实验室提供了一份资料,里面包含了3份文档以及一个apk。
三份文档的内容大致为:
ESIM功能可以简单理解为,ESIM厂家提供芯片,芯片分为贴片式跟拔插式,贴片式是贴到主板上,类似于各种单片机;而拔插式则是一张实体ESIM卡,长得跟普通的SIM卡一样,需要插入到卡槽中才能使用;然后,就到ESIM运营商购买ESIM卡号,安卓系统就可以通过谷歌LPA服务将购买的ESIM卡号下载到ESIM芯片中,下载完成启用ESIM卡就能正常使用了,一张ESIM芯片可以下载多个ESIM卡,但是,设备最多只能启用一张ESIM。
实现流程
在验证ESIM功能之前,可以先到设置-关于手机-sim卡详细信息
中查看是否有EID,EID是ESIM芯片的唯一标识,代表着ESIM的正常使用,如果设备无法读取到EID,得排查硬件通路以及modem。
- 启用euicc的feature
- 内置谷歌LPA服务到system/priv–app/
- 给LPA服务增加priv–app权限或者关闭权限校验
- 增加overlay app
- 在系统设置中,调起LPA服务下载ESIM卡号,并启用ESIM
framework中已经有euicc的feature,只需要拷贝到设备即可

给LPA服务增加priv-app权限或者关闭权限校验,这里选择的是关闭权限校验

增加overlay app,这个app是自己写的,需要实现几个功能

android:exported="true">

<integer name="download_type">3</integer>
谷歌LPA就是通过广播找到overlay app,然后从app的资源文件中获取sim_slot_mappings_json的值,拿到配置数据,其中devices的值要修改为Build.DEVICE,如果是其他项目移植要记得修改。后面的esim是虚拟sim卡,psim是物理sim卡,ids的值分别是对应的卡槽,比如在SIM 1卡槽接了ESIM,这里就配成0,不过实际测试,不过怎么配置ids,都能使用ESIM。
在系统设置中,调起LPA服务下载ESIM卡号,并启用ESIM
按照上面的方式集成之后,在系统设置–网络–移动网络选项,如果没有下载过ESIM,点击就会调起谷歌LPA服务,或者可以通过adb广播调起LPA配置界面,然后根据提示,扫描二维码,下载ESIM卡号即可。
adb shell am start -n
"com.google.android.euicc/com.android.euicc.ui.settings.CurrentProfileListActivity"
其他问题
之前在2290上面调试,出现下载完ESIM卡号之后,无法启用ESIM功能,需要在ESIM界面开、关一次飞行模式,ESIM启用按钮才可以点击。解决方案如下:

在MTK8766中同样出现不可点击的问题,而且还把白卡显示出来,造成了混淆,解决方案如下:

MTK8766下载完ESIM卡号之后,有信号,能ping通百度,但是浏览器无法上网,最终定位是他们默认APN配置的问题
