Getting Intent data regardless of status of receiving activity

Question

I have a an activity that sends data to another in the usual android way (by using putExtras)

i.putExtra("ID_NUMBER", id);

But I have an activity that can be either closed or in the background when this intent is sent. I am using the following method to catch the intent when my activity is in the background:

protected void onNewIntent(Intent intent) {
    String id = intent.getStringExtra("ID_NUMBER");
}

But I've noticed this method does not get called when the activity is created. Is there a catch all method that intents pass through when entering an activity or is the standard way of doing this to get the Intent in OnCreate()?

Answer 1

Extract the code to react on new intent and put it also into onCreate :

@Override
protected void onCreate(...) {
    doOnNewIntent( getIntent() );
}

@Override
protected void onNewIntent(Intent intent) {
    doOnNewIntent( intent );
}

private void doOnNewIntent(Intent intent) {
    String id = intent.getStringExtra("ID_NUMBER");
}
