Android Question SENTINEL_MSG entries in log?

[Dave O]

Hi all,

Just recently, I've started seeing the following messages appear in my log when running the B4A rapid debugger:

SENTINEL_MSG_LIBCUTILS
SENTINEL_MSG_LIBLOG

Anyone know what this is?

My app is only using a few (common) libraries: Core, JavaObject, Phone, Reflection, so I doubt these messages are coming from them.

Such messages are not printed from any of the official libraries.

I've now managed to capture the unfiltered logs before and after the messages occur.

I killed off all foreground apps on my Nexus 5X. (There were still a load of processes running in the background). I then opened a blank B4A project. I then physically connected the USB lead to the Nexus 5x and then I selected "Connect" from the "Logs" tab. (It wasn't connected before because I has a 2nd virtual device to which I could also connect.)

This is a snippet of the unfiltered log

ANDROID_BACKGROUND_ACTION { action: PLATFORM_QUERY param: GOALS_QUERY param2: 0 duration: 13710 status_code: SUCCESS release: TOMBA query: GOALS_QUERY }
ANDROID_BACKGROUND_ACTION { action: PLATFORM_QUERY param: GOALS_QUERY duration: 13741 status_code: SUCCESS release: TOMBA query: GOALS_QUERY }

i'm not sure if the messages "Logcat interceptor installed successfully" refers to the use of the Basic4Android Log Viewer.

This is not very enlightening, but it does seem that this message does not come from the current B4A app. I couldn't find any other references to this message on Google.

They do not come from B4A.
