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
1、如何集成LPA2、如何实现overlay app3、如何在开机向导和系统设置增加ESIM选项
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EIDEID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。
ESIM功能都实现流程可以分为以下几个步骤
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

在AndroidManifest.xml中注册广播 receiverandroid:name.PartnerReceiverandroid:permissionandroid.permission.WRITE_EMBEDDED_SUBSCRIPTIONSandroid:directBootAwaretrueandroid:exportedtrueintent-filteraction android:namecom.google.android.euicc.action.PARTNER_CUSTOMIZATION //intent-filter/receiver在java文件中实现广播并且广播方法中必须为空
package com.tp.euicc.overlay;import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;public class PartnerReceiver extends BroadcastReceiver {public PartnerReceiver() {}Overridepublic void onReceive(Context context, Intent intent) {}
}在res/values/strings.xml中增加两个字段 string namesim_slot_mappings_json translatablefalse{sim-slot-mappings:[{devices:[custom_go],esim-slot-ids:[0],psim-slot-ids:[1]}]}/stringinteger namedownload_type3/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P8KR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

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
