Alternative Solution storing variable as string instead of int

private String user = "10"; instead of int value

-> outState.putString(KEY_VALUE, user);

this was not accepted as a solution.

MainActivity.java
import android.content.Intent;
import android.view.View;

public class MainActivity extends Activity {

  public static final String KEY_USERENTRY = "KEY_USERENTRY"; 
  public TextView mTextView;

  private int user = 10; 

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mTextView = (TextView) findViewById(R.id.textView);
  }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);

      outState.putString()

    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);

    }
}

Since you want to store an int, you can do this:

outState.putInt(KEY_USERENTRY, user);
