[QCM6125][Android13] 默认授予所有应用运行时权限

开发平台基本信息

芯片: QCM6125
版本: Android 13
kernel: msm-4.14

问题描述

Android6.0以上增加了运行时权限，应用要想使用例如相机、存储等权限，除了在AndroidManifest.xml中声明，还需要在JAVA文件中进行动态申请权限。而对于我们这种智能硬件设备，客户应用几乎都是霸屏并且具有系统签名的高权限应用，这时候运行权限机制就显得有点多余；所以一般我们拿到一套新的代码，除了与支付相关或者一些认证相关，例如GMS认证等特殊设备，正常都是会默认授予应用运行时权限以及开发SELinux权限。
