如果reason 属于弱集(包含空值),从 last klog 中查找信息,检查是否电池耗尽引起死机,根据 persist.sys.boot.reason 修正 reason。 如果上述操作依然无法确定 reason,将值设置为 reboot,<boot_reason>。如果 reason 属于内核集,重写 persist.sys.boot.reason。 二、原因格式 1. 启动原因格式在 Android 9 中,ro.bo...

public void reboot (String reason) 对于这个接口的描述很简单,就是几句话。 接口的作用就是重启设备,而且,就算重启成功了也没有返回值。 需要包含REBOOT权限,也就是android.permission.REBOOT 唯一参数reason代表需要的特定重启模式,比如recovery,当然也可以为null。
