2. Create a class MyLog.Java and update it-
   
   
   
   
   

   package pankaj.log.demo;
   
   import android.util.Log;
   
   /**
    * Created by gsolc-05 on 30/7/17.
    */
   
   public class MyLogs {
       static String TAG = "DEMO_LOG";
   
       public static void LogMessage(String message) {
           StackTraceElement l = new Exception().getStackTrace()[1];
           Log.e(TAG, l.getClassName() + "->" + l.getMethodName() + " : " + l.getLineNumber() + " : " + message);
       }
   
   
   }
   
   
   
   

    
4. Create a class MainActivity.Java and update it-
   
   
   
   
   

   package pankaj.log.demo;
   
   import android.support.v7.app.AppCompatActivity;
   import android.os.Bundle;
   import android.view.View;
   
   public class MainActivity extends AppCompatActivity {
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
           MyLogs.LogMessage("HELLO...");
       }
   
       public void helloPrint(View view) {
           MyLogs.LogMessage("HELLO...");
       }
   
       public void hiPrint(View view) {
           MyLogs.LogMessage("HI...");
       }
   }
   
   
    

    
5. Open your main_activity.xml file and update it-
   
   
   
   

   <?xml version="1.0" encoding="utf-8"?>
   <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
       xmlns:tools="http://schemas.android.com/tools"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       tools:context="pankaj.log.demo.MainActivity">
   
   
       <TextView
           android:layout_width="match_parent"
           android:paddingTop="20dp"
           android:layout_height="wrap_content"
           android:gravity="center"
           android:text="Press buttons to print logs" />
   
       <LinearLayout
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:gravity="center"
           android:orientation="vertical">
   
           <Button
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:onClick="helloPrint"
               android:text="PRINT HELLO... LOG" />
   
           <Button
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:onClick="hiPrint"
               android:text="PRINT HI... LOG" />
   
   
       </LinearLayout>
   
   
   </android.support.constraint.ConstraintLayout>
   
   
   
   

   
   
6. All the application development process with CustomLogs has completed, Now run the app and look the screen.
