Is it possible to send a signal from an intent and recover it in another intent-CodePudding

I have 2 activities.. one is launched via deep links. MainActivity doesn't start DeeplinkActivity. How do I know from MainActivity when DeeplinkActivity finishes.

I have tried setting an intent filter programmatically. then added it to MainActivity then in DeeplinkActivity sendBroadcast.

I was unsuccessful since the broadcast recover method in MainActivity wasn't responding to broadcast sent from Deeplink via sendBroadcast(getIntent())

The function you are looking for is putExtra() put this in your FirstActivity :

Intent intent  = new Intent (FirstActivity.this , SecondActivity.class);
intent.putExtra("your key" , yourBooleanVariable) ;
FirstActivity.this.startActivity(intent) ;

And this code in Your Second Activity :

Intent intent = getIntent() ;
Bundle bundle = intent.getExtras();
if(intent.hasExtra("your key")){
Boolean boolean = bundle.getBoolean();
}

you can put everything in a bundle with putExtra and get it from the bundle in the second Activity

You can use interface, inside onDestroy() of DeepLink activity call the interface method and implement the method in MainActivity. Check this answer. https://stackoverflow.com/a/19027202/7248394
