Hi, can someone please show me where the bug is? Thanks!

import android.os.Bundle;
public class MainActivity extends Activity {
protected SharedPreferences mSharedPreferences;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);
// Some code omitted!
}
public int getMeaningOfLife() {
return mSharedPreferences.getInt("MeaningOfLife", 42);
}
public void setMeaningOfLife() {
mSharedPreferences
.edit()
.putString("MeaningOfLife", "42")
.commit();

I don't want to give you the exact answer as I think you will benefit greatly from figuring it our for yourself however, concentrate on the method below (HINT: check the data types)
public void setMeaningOfLife() {
mSharedPreferences
.edit()
.putString("MeaningOfLife", "42")
.commit();
}
Hope this helps
