Log.d not showing log.d in Logcat Android Studio

Question

Android studio does not show any Logs I wrote in my code. I have tried putting the log to verbose and debug. I am using 'No filters'. Why is 'Oncreatetestlog' not showing up in my logcat?

package com.example.keydown;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        if (savedInstanceState != null) {
            Log.d("Oncreatetestlog", "onCreate() Restoring previous state");
            /* restore state */
        } else {
            Log.d("Oncreatetestlog2", "onCreate() No saved state available");
            /* initialize app */
        }
    }
}

`if (savedInstanceState != null)` did you put anything into the savedInstanceState to make it not null? — justHooman, Oct 08 '16 at 15:06
@Minhtdh Well there's an else, so it should always show something. — P.Yntema, Oct 10 '16 at 15:32
There are many options on the left side of the logcat, tweeking them sometimes stops the logcat temporarily — Mohammed Atif, Oct 10 '16 at 16:58

Go to File -> invalidate caches / Restart. And let Android Studio index your project again. It works for me.

I tried, when I search the logcat for 'Oncreatetestlog' it doesn't show anything. Still not writing. – P.Yntema Oct 10 '16 at 15:40
This helped me when new logging was making no effect on Android Emulator.. – Štěpán Apr 01 '20 at 14:45

For anyone coming back to this: modify the filters. Mine was set to firebase for some reason, which *sometimes* but not always hides your messages. Not sure why. – Kraigolas Sep 09 '20 at 12:51

After hours of searching and trying, I found out it did not have to do with Android Studio, but that my phone didn't allow Logging. See this answer for more information.

Alternatively, you could use System.out.println() to show the text in logcat

Replace

Log.d("Oncreatetestlog", "onCreate() Restoring previous state");

With

System.out.println("Oncreatetestlog onCreate() Restoring previous state");

If Log.d is not showing in your Logcat just replace Log.d with Log.wtf Like this:

Replace:

Log.d("tag",""+catstr);

With:

Log.wtf("tag",""+catstr);

It Works..happy coding;)

I swear I thought this StackOverflow answer was a joke. IT IS NOT! It really did work for me. Never figured out why Log.d stopped logging for me, but this works great! – gcdev Dec 08 '22 at 20:25
