Shared Preference Android Storing Data

I am having trouble storing data using shared preference. If I have the following code and try to run it, it crashes. I don't know why though. public class Favorites extends Activi

Solution 1:

change

SharedPreferencespref= getSharedPreferences("Preference",
            MODE_WORLD_READABLE);

to

SharedPreferencespref= getSharedPreferences("Preference",
            MODE_WORLD_WRITABLE);

Solution 2:

Try this, maybe it is due to null pointer exception.I am not sure.

publicclassFavoritesextendsActivity{

    privatestaticfinalStringTAG_NAME="title";
    privatestaticfinalStringTAG_URL="href";


    publicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.favorites);

        Intentin= getIntent();
        TextViewfavName= (TextView) findViewById(R.id.textView1);

        StringFILENAME="settings";
        Stringstring="hello world!";

        SharedPreferencespref= getSharedPreferences("Preference",
                MODE_WORLD_READABLE);
        SharedPreferences.Editoreditor= pref.edit();
        editor.putBoolean("keyBoolean", true);
        editor.putFloat("keyFloat", 1.0f);
        editor.putInt("keyInt", 1);
        editor.putLong("keyLong", 1000000L);
        editor.putString("keyString", "Hello Android");
        editor.commit();

        booleandataFromPrefBool= pref.getBoolean("keyBoolean", null);
        floatdataFromPrefflaot= pref.getFloat("keyFloat", null);
        intdataFromPrefInt= pref.getInt("keyInt", null);
        longdataFromPrefLong= pref.getLong("keyLong", null);
        StringdataFromPrefString= pref.getString("keyString", null);

        if(dataFromPrefInt==null)
        {
            favName.setText("");
        }
        else
        {
            favName.setText(dataFromPrefInt);
        }
    }
}
