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 */
        }
    }
}

Answer 1

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

Answer 2

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.

Answer 3

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");

Answer 4

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;)
