Error: There is no resource associated with id: 10. Note: setText(int) is not the same as setText(String).
import android.content.Intent;
import android.view.View;
public class MainActivity extends Activity {

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

}
@Override

super.onSaveInstanceState(outState);
outState.putInt(KEY_USERENTRY, 10);

mTextView.setText(savedInstanceState.getInt(KEY_USERENTRY) + "")
We have to put the + "" outside the getInt() method. The getInt() method will only take in a key value and then we covert it to a string afterwards

15,353 PointsHey House,
From the looks of it, your problem is that you are trying to set an int value as the mTextView text. Therefore just add + "" after KEY_USERENTRY and thisll convert the int to a string. Then I believe it should work

Thanks for your reply. I tried what you suggested, but got another error.
"Remember to provide the key to the getInt method."
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
mTextView.setText(savedInstanceState.getInt(KEY_USERENTRY + ""));
}
