@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mCheckBox = (CheckBox) findViewById(R.id.checkBox);
mSharedPreferences = getSharedPreferences(PREFS_FILE, Context.MODE_PRIVATE);
mEditor = mSharedPreferences.edit();
Boolean value = mSharedPreferences.getBoolean(KEY_CHECKBOX, false); //we are getting a boolean not a string. //and we want the default value to be false as stated in the instructions
mCheckBox.setChecked(value); //put in the above boolean value. true will make it checked, false is unchecked
}
@Override
protected void onPause() {
super.onPause();
mEditor.putBoolean(KEY_CHECKBOX, mCheckBox.isChecked()); //this is the method that u need to use which will //return a boolean value depending on if the checkbox is checked or not
mEditor.apply();
}
I added comments in the above code showing you where you went wrong.
