Custom Logs

Custom Logs is used to show all information's of logs (like name of class->function->line number->tags and message).




Steps to use Custom Logs in your project.

  1. Crate a project(LogsDemo) in android studio.

  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);
        }
    
    
    }
    
    
    
    
    
     
  3. 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...");
        }
    }
    
    
    
     
     
  4. 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>
    
    
    
    
    

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