Hey,
to start an activity you need a “parent activity”, so if you would like to start your new activity from SmsRx,
one option is to keep a copy of the activity that instantiated SmsRx, and pass it in the constructor or afterwards.
Ex: class A extends Activity
{
…
SmsRx s = new SmsRx(this);
…

in SmsRx constructor save the parent, ex:
public SmsRx(Activity p)
{
Activity parent = p;
}

and than when you want to start the new activity, just use the parent.

Good luck.

Intent i = new intent();
i.startActivity(??????,newactivity.class);
