Restore the edit text value entered

The value is entered in edit text in Activity A. When going to another activity B without saving and coming back A , the value of form in edit text in Activity A gets cleared. How can the edit text value gets restored?

 @Override
protected void onSaveInstanceState(Bundle outState) {

    outState.putString("company", company.getText().toString());
    outState.putString("name", name.getText().toString());
    outState.putString("email",email.getText().toString());
    outState.putString("phone",phone.getText().toString());
    outState.putString("address",address.getText().toString());
    outState.putString("desc",desc.getText().toString());
    super.onSaveInstanceState(outState);
}
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
     co = savedInstanceState.getString("comoany");
     em = savedInstanceState.getString("email");
     ph = savedInstanceState.getString("phone");
     add = savedInstanceState.getString("address");
     na = savedInstanceState.getString("name");
     de = savedInstanceState.getString("desc");
}

@Override
protected void onResume() {

    Log.i("this", "Company::::::::::::" + co);
    company.setText(co);
    super.onResume();
}

what you need is to override onSaveInstanceState in your activity A and store the value of your edit text as follows:

 @Override
public void onSaveInstanceState(Bundle outState) {

outState.putString(TEXT_VIEW_KEY, mTextView.getText());

// call superclass to save any view hierarchy
super.onSaveInstanceState(outState);

}

and in your onCreate activity should now check if there is any data that was previously saved and then initialize your textview 

@Override
public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

// recovering the instance state
if (savedInstanceState != null) {
    String text  = savedInstanceState.getString(TEXT_VIEW_KEY,);
}


setContentView(R.layout.main_activity);

// initialize member TextView so we can manipulate it later
mTextView = (TextView) findViewById(R.id.text_view);
mTextView.setText(text);

}

You may also want to check on architecture components for android specifically the life cycle aware components to easen your work nxt time

This is not default behavior of Android.

Activity A will retain values until it is finished (destroyed). Check if you are not calling finish() after startActivity().

Some solutions can be.
