Hi,
I am starting a new activity from my existing one like this -
Tring.java
 Intent intent = new Intent(tring, NumberActivity.class);
startActivityForResult(intent,1);

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
Log.d("Tring","Inside onActivityResult of Tring");
        if (requestCode == 1) {
            if (resultCode == RESULT_OK) {
                this.finish();

            }
        }
    }



Now in NumberActivity.java i have the following piece of code :
setResult(RESULT_OK, null);
          finish();

According to what i have read this should close out my current Activity (ie. NumberActivity) and call onActivityResult method of Tring.java inside which i have made a call to finish. so the parent activity gets finished.
But this is not happening.

Please help.
thanks

one way to approach this is to kill your parent activity when you start the child activity.  that way when you finish with the child activity, you can exit without worrying about the parent activity.  if you need the parent activity, just have the child activity call the parent activity.  then you just have to worry about storing the information of the parent (if any) in order to call it again.

to kill the parent activity after calling the child, override the onPause function and tell it to finish there.  for example:

@Override
protected void onPause() {
    super.onPause();
    finish();
}

Open in new window


good luck!
