When the app is restarted it returns the default value instead of the
previously saved value. I need some help.
The main problem here is that I have followed the steps that sharedpreferences demands, the is saved but cannot be restored on app re-open.

The default value in returned when the app is re opened ie
Score=myScore.getInt ( "score",0 );

Here is the sample of the score
app code.

package tips.admin.tipsscore.score;
import android.content.Context;
import android.content.SharedPreferences;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity 
 TextView score;
Button add,sub;
Context context;
int Score=0;
 @Override
 protected void onCreate(Bundle savedInstanceState) 
 super.onCreate ( savedInstanceState );
 setContentView ( R.layout.activity_main );
 score=(TextView)findViewById ( R.id.score );
 add=(Button)findViewById ( R.id.increase );
 sub=(Button)findViewById ( R.id.decrease );
 SharedPreferences myScore=context.getSharedPreferences ("myscore", Context.MODE_PRIVATE);
 Score=myScore.getInt ( "score",0 );
 score.setText ( "SCORE : "+Score );
 add.setOnClickListener ( new View.OnClickListener () 
 @Override
 public void onClick(View v) 
 Score+=45;
 SharedPreferences sharedPreferences=getSharedPreferences ("myscore", Context.MODE_PRIVATE);
 SharedPreferences.Editor editor= sharedPreferences.edit ();
 editor.putInt ( "SCORE : ",Score);
 editor.commit ();
 score.setText ( "SCORE : "+Score );

 
 );
 sub.setOnClickListener ( new View.OnClickListener () 
 @Override
 public void onClick(View v) 
 Score-=21;
 SharedPreferences sharedPreferences=getSharedPreferences ("myscore", Context.MODE_PRIVATE);
 SharedPreferences.Editor editor= sharedPreferences.edit ();
 editor.putInt ( "SCORE : ",Score);
 editor.commit ();
 score.setText ( "SCORE : "+Score );
 
 );
 

You using a different keys for saving and restroring value from shared preferences.
You need to use a same key.

For example:

save:

editor.putInt ("score_value", Score);

read:

myScore.getInt ("score_value", 0);

Use string constants instead, to avoid misspelling your tags.

In your class declare :

private static final String NAME_OF_TAG = “name_of_tag”

Then use that string instead:

editor.putInt(NAME_OF_TAG, 3);

int value = preferences.getInt(NAME_OF_TAG, 0);
