Android Android Activity Lifecycle The Activity Lifecycle Saving and Retrieving Instance State

In the onInstanceState method, save number 10 to bundle

I have no clue of how this has to be done.

MainActivity.java
import android.content.Intent;
import android.view.View;

public class MainActivity extends Activity{

  public TextView mTextView;
  public static final String KEY_USERENTRY = "KEY_USERENTRY";

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

    mTextView = (TextView) findViewById(R.id.textView);
  }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);


    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);

    }
}

Hi Sanchit,

Perhaps something like:

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putInt(KEY_USERENTRY, 10);

    }
