问题 I've got an Android application which needs to be woken up sporadically throughout the day. To do this, I'm using the AlarmManager to set up a PendingIntent and have this trigger a BroadcastReceiver. This BroadcastReceiver then starts an Activity to bring the UI to the foreground. All of the above seems to work, in that the Activity launches itself correctly; but I'd like the BroadcastReceiver to notify the Activity that it was started by the alarm (as opposed to being started by the user).

问题 This question relates to Android versions pre-Lollipop. For Lollipop API, check related question: Lollipop API for controlling the Alarm icon in status bar I would like to know how to turn on / off the system Alarm icon in the status bar as shown in this image: From what I understand about the system, and what I've read in the past, it is controlled by the built in system alarm clock app. And 3rd party apps have no control over it on an unrooted device.

问题 I am trying to change my marker based on an alarm I've created in Thingsboard. Currently the marker is displaying data from my "datasource" entity. However there is no way (that I have seen) that you can add an "Alarm source" similar to the alarm widget. The data available is "f(data, images, dsData, dsIndex)" which I assume is only the data telemetry. Basically I need to change the marker if an alarm is going off. My alarm trigger only goes off momentarily so I can't use my data telemetry

So the compiler goes pauses the execution of function X and goes to function Y . After finishing the function Y the compiler again continues the execution of programme X from where it was
