Question

我正在尝试建立一个类似于活动的立场，而且我接近我的目标，我发现的唯一问题是有时在我关闭屏幕之后Android会立即打开它，我无法理解为什么

我有一个链接到专用主板的终端，当我启动一个特定的活动时，我可以让主板向我的设备发送消息以关闭屏幕。结果是屏幕关闭，但只是暂时，因为Android立即打开屏幕。

这是我的应用程序的日志

         V/KeyguardServiceDelegate( 2147): **** SHOWN CALLED ****
         I/WindowManager( 2147): No lock screen! windowToken=null

我无法理解的奇怪日志是这一行

         D/InputManager-JNI( 2147): handleInterceptActions: Waking up.

似乎不知怎的，即使我没有输入，InputManager类也会收到唤醒屏幕的输入。有人知道为什么会这样吗？

Answer 1

D / InputManager-JNI（2147）：handleInterceptActions：醒来。

这意味着带有策略标志“wake”的键或其他事件即将发生。

屏幕无缘无故开启
