Question: ```
@Override

 super.onCreate(savedInstanceState);
 setContentView(R.layout.login);

@Override

  // TODO Auto-generated method stub
  String  phonenumber= savedInstanceState.getString("PhoneNumber");

  super.onRestoreInstanceState(savedInstanceState);
}

```

I have one editText (for typing phone number). When in portrait mode I type the numbers and after that rotating the phones, the typed data is gone. I save data savedInstanceState but I have no idea how can I restore my typed data when I rotate the phone. Any help please.

Answer: 
On simple way is to avoid having your activity recreated on rotation. Change your AndroidManifest.xml to include `android:configChanges="keyboardHidden|orientation"` like this:

```
<activity android:name="MyActivity" android:configChanges="keyboardHidden|orientation"></activity>

```

Your layout will need to support whatever orientation the device supports. Also there are some other things to consider: [Why not use always android:configChanges="keyboardHidden|orientation"?](https://stackoverflow.com/questions/7818717/why-not-use-always-androidconfigchanges-keyboardhiddenorientation)
try to move getting phone number from onRestoreInstanceState to onCreate method
or try something like this:

```
@Override
public Object onRetainNonConfigurationInstance()
{        
    return phoneNumberLogin.getText().toString();
}

```

and in onCreate

```
@Override
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.login);
   String  phonenumber= (String)getLastNonConfigurationInstance();
   if (phonenumber != null) {
      EditText FirstName = (EditText) findViewById(R.id.editTextname);
      FirstName.setText(phonenumber);
   }
}

```
