Android Question Does Function Log(something) run on real phone?

[tuhatinhvn]

When we code and debug , we often use. Function Log(something) to show value of it

But i want to ask when apk run on real phone,this function can make app run slowly??

LOG is only written when compiled in debug. An working app should be compiled in Relese-mode. LOGs are not written to log in release-mode.
So you can let the LOG-commands in.

Unless you are dumping a significant amount of data it should make no noticeable difference.

Logs are written to log in release mode.

Ahh, ok. But the log is not shown in b4a when running an app in release-mode?

 

[thedesolatesoul]

You mean in the B4A IDE? It is shown there too.

I have something in mind i have read that somewhere here in forum from erel... Excuse me if i´m wrong.

It could be this what i have in mind...

Ah I see.
You mean the B4A Bridge does not read the logs? I thought it uses the 'READ_LOGS' permission just to do that.
I always use USB Debugging which always reads the logs.
Thank you for correcting me.

The explanation is here: B4A-Bridge and Android 4.1+ logs

Starting from Android 4.1 each process can only read its own logs. The "read logs" permission no longer works. The only exception is when you are connected in USB debugging mode (ADB). When you run your app in debug mode with B4A-Bridge connected it send the logs to the bridge app.
