Task A:
A1: Execute console [Command: logcat -c Countdown (seconds): 0 Use Root: Off Store Output On:% logcat Store Errors In: Store Result in:]
A2: Execute Console [Command: logcat -f /sdcard/taskerlogcat.txt Countdown (seconds): 0 Use Root: Off Store Output On:% logcat Store Errors In: Store Result in:]
Task B:
A1: Stop [Failed: Off Task: Task A
However, I do not know what happens to the logcat log run from Tasker, which does not give complete information.
When I run logcat from "emulator terminal" it gives much more information.
