How to use putExtra() and getExtra() for string data

Use this to “put” the file…

Intent i = new Intent(FirstScreen.this, SecondScreen.class);   
String strName = null;
i.putExtra("STRING_I_NEED", strName);

Intent i = new Intent(FirstScreen.this, SecondScreen.class);

String strName = null;

i.putExtra("STRING_I_NEED", strName);

Then, to retrieve the value try something like:

String newString;
if (savedInstanceState == null) {
    Bundle extras = getIntent().getExtras();
    if(extras == null) {
        newString= null;
    } else {
        newString= extras.getString("STRING_I_NEED");
    }
} else {
    newString= (String) savedInstanceState.getSerializable("STRING_I_NEED");
}

String newString;

if (savedInstanceState == null) {

Bundle extras = getIntent().getExtras();

if(extras == null) {

newString= null;

} else {

newString= extras.getString("STRING_I_NEED");

}

} else {

newString= (String) savedInstanceState.getSerializable("STRING_I_NEED");

}

String restoredText = prefs.getString("text", null);
if (restoredText != null) {
  String name = prefs.getString("name", "No name defined");//"No name defined" is the default value.

if (restoredText != null) {

String name = prefs.getString("name", "No name defined");//"No name defined" is the default value.

int idName = prefs.getInt("idName", 0); //0 is the default value.
