How to get value of SharedPreferences android

I'm trying to use SharedPreferences here is what i do

public void StoreToshared(Object userData){
    SharedPreferences mPrefs = getPreferences(MODE_PRIVATE);
    SharedPreferences.Editor prefsEditor = mPrefs.edit();

    Gson gson = new Gson();
    String json = gson.toJson(userData);
    Log.d("data", " Setup --> "+json);
    prefsEditor.putString("userinfo", json);
    prefsEditor.commit();

}

Log.d result is like this

 Setup --> {"nameValuePairs":{"userData":{"nameValuePairs":{"phone":"089688xxxxxxx",
  "username":"username of User","flag":1,"Email":"mymail@mail.com",
  "tipe":"TP001","Deskripsi":"Ini tentang gua","user_id":"USER001",
 "password":"c83e4046a7c5d3c4bf4c292e1e6ec681","fullname":My fullname"}},"status":"true"}}

then i'm trying to retrieve it, in other activity here is what i do

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

        SharedPreferences mPrefs = getPreferences(MODE_PRIVATE);
        SharedPreferences.Editor prefsEditor = mPrefs.edit();

        String data = mPrefs.getString("userinfo", null);
        Log.i("Text", "Here is the retrieve");
        Log.i("data", " retrieve --> "+data);

    }

and here how i open my other activity

Intent intent = new Intent(Login.this, MainActivity.class);
startActivity(intent);

With my script above, the result from my logcat , i only see like Log.d above. So my question is, how can i retrieve it ?

Try to add a key on your SharedPreferences:

public void StoreToshared(Object userData){
    SharedPreferences mPrefs = getSharedPreferences("your_sp_key", MODE_PRIVATE); //add key
    SharedPreferences.Editor prefsEditor = mPrefs.edit();

    Gson gson = new Gson();
    String json = gson.toJson(userData);
    Log.d("data", " Setup --> "+json);
    prefsEditor.putString("userinfo", json);
    prefsEditor.commit();

}

Retrieval:

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

    SharedPreferences mPrefs = getSharedPreferences("your_sp_key", MODE_PRIVATE); //add key
    SharedPreferences.Editor prefsEditor = mPrefs.edit();

    String data = mPrefs.getString("userinfo", null);
    Log.i("Text", "Here is the retrieve");
    Log.i("data", " retrieve --> "+data);

}
