Android8.1 OTA升级之后Settings 新添加键值没有初始化

Android8.1 OTA升级之后Settings 新添加键值没有初始化

软件平台：Android8.1

硬件平台：展讯

问题：系统升级后，新添加的Settings键值没有更新至系统，经查发现Settings的数据库更新在SettingsProvider有更新触发条件，就是SETTINGS_VERSION和currentVersion两个值，这俩值是一个同步递增的过程，如果SettingsProvider更新了一些键值，而不递增SETTINGS_VERSION的值，升级后就不会触发更新，具体改动如下：

这样的话，在OTA升级完成后会更新db数据库，完美解决～～～
