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?

To Reproduce
Steps to reproduce the behavior:
Hard to reproduce, happens randomly

Environment
tinylog version: 2.7.0
Android Version: 13
Java version: 8

The writing thread has to be enabled globally instead on a writer.

Just replace

writer2.writingthread = true

with

writingthread = true

I tried this too, and it didn't seem to make any difference.

Therefore I looked into the code and I can't really find any code where an actual thread is created when the flag is set.
I only find the part where the flag makes it not synchronized.

if (writingThread) { internalWrite(data); } else { synchronized (writer) { internalWrite(data); } }

Am I missing some code where an actual second thread is created or is that all setting writingThread does?
