Android EMM设置应用最低版本后未触发自动更新问题咨询

现象描述 #

• 操作配置：通过EMM API将Play Store私有应用的最低版本号设置为10，同时将应用自动更新模式设为高优先级
• 设备状态：设备当前安装的该应用版本为9，应用运行在Kiosk模式下
• 实际表现：未触发预期的自动更新流程，仅在设备屏幕弹出警告，提示若不更新应用设备将被擦除

问题根因 #

• 本次异常由旧策略中的installAppsDisabled: true配置导致：该配置会全局禁用设备的应用安装权限，同时会阻断应用自动更新的执行流程
• 上述展示的策略已移除该配置项，可正常触发应用自动更新逻辑
