Tinylog doesn't seem to log on different thread on android

[leschbenedikt]

Describe the bug
I am occasionally getting an ANR on Android 13 which is caused by tinylog.
The ANR log clearly shows that tinylog tries to write the log on the main thread although i've set the property writingthread to true.

For me this seem like a bug or am I doing something wrong?
