Thank you Mark - this was never very clear in any of the books I've bought
regarding Android programming or on Android website unfortunately.
My next question is as follows:
I've listed a receiver in the manifest as suggested pointing to the
following definition:
public class TESTWAKEUP extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Intent rerun=new Intent(context,MyApp.class);
rerun.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
rerun.putExtra("fromstaticreceiver", "parameter");
context.startActivity(rerun);
}
}
}
Now, for some reason, when my activity is brought back to the foreground by
the about receiver (which is triggered by a Service), it does not seem that
the extra parameter is ever receiver:
@Override
public void onCreate(Bundle savedInstanceState) //this is for MyApp
{
Intent argv=getIntent();
Bundle bundle = argv.getExtras();
String fromstaticreceiver=null;
if (bundle != null)
fromstaticreceiver = bundle.getString("fromstaticreceiver");
Log.d("here:", "fromstaticreceiver=" + fromstaticreceiver);
//always shows null for fromstaticreceiver
My question is:does getIntent() represent the argument of the intent that
originally started the activity or does it reflect intent in the system
that are forcing an activity to come to the foreground?
Many thanks for any feedback on this front.
Rdgs,
