Android Publish an Android App Publishing on Google Play Building a Release-Ready APK

I kept getting this error on the last step for Building a Releasse Ready APK

Error:Execution failed for task ':app:proguardRelease'.

proguard.ParseException: Expecting opening '{' at 'Log' in line 18 of file 'C:\Users\Slim Jim\AndroidStudioProjects\FunFacts\app\proguard-rules.pro'

Here is my code

FunFactsActicity Code

package com.example.slimjim.funfacts;

import android.app.Activity; import android.graphics.Color; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.Button; import android.widget.RelativeLayout; import android.widget.TextView; import android.widget.Toast;

import java.util.Random;

public class FunFactActivity extends Activity { public static final String TAG = FunFactActivity.class.getSimpleName(); private FactBook mFactBook= new FactBook(); private ColorWheel mColorWheel = new ColorWheel();

@Override // used to separate methods
protected void onCreate(Bundle savedInstanceState) { // void is a place holder  which let
    // let the compiler no you returning nothing

    //Declare our View Variables and assign the View label from the layout file
    final TextView factLabel = (TextView) findViewById(R.id.factTextView);
    final Button showFactButton = (Button) findViewById(R.id.showFactButton);
    final RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.relativeLayout);

    View.OnClickListener listener = new View.OnClickListener() { //listener is the variable for
        //on click lister function
        @Override // prewritten once a new variable was created for on click variable
        public void onClick(View view) {
            String fact = mFactBook.getFact();


            int color = mColorWheel.getColor();

    };// a semicolon had to be added here
    showFactButton.setOnClickListener(listener);// you had to add the declare variable here to
    //listener inside () to remove function
   // Toast.makeText(this,"Yay ! our activity was created", Toast.LENGTH_LONG).show();
     Log.d(TAG,"We are logging from the onCreat() method");

    /* make toast message long way
    String message = "Yay ! our activity was created";
    Toast welcomeToast = Toast.makeText(this,message, Toast.LENGTH_LONG);


proguard-rules pro code

Add project specific ProGuard rules here.

By default, the flags in this file are appended to flags specified

in C:\android-studio-bundle-windows\android-studio\sdk/tools/proguard/proguard-android.txt

You can edit the include path and order by changing the proguardFiles

directive in build.gradle.

For more details, see


Add any project specific keep options here:

If your project uses WebView with JS, uncomment the following

and specify the fully qualified class name to the JavaScript interface


-keepclassmembers class fqcn.of.javascript.interface.for.webview {

public *;


-assumenosideeffects class android.util Log { public static boolean isLoggable(java.lang.String,int); public static int v (...); public static int i (...); public static int w (...); public static int d (...); public static int e (...); }

I don't understand what wrong my code runs fine, but I kept receiving the error above so I cannot generate a sign APK
