Android Studio Tutorial - 55 - Bound Service Using Messenger

thanks !

this is only one course in the dark in the world

source code?

I noticed that this app crash when I rotate the smartphone with this exception:
"java.lang.RuntimeException: Unable to stop activity{......MainActivity}: java.lang.IllegalArgumentException: Service not registered..." does anyone know what to do?

I am confused with the final else block in the sayHello function. How it is going to execute if we click the sayhello or say hello again first( without clicking the bind service button)? Any kind of help is really appreciated.

Sir, your tutorial helped me lot...Thank you so much.

Why don't just call public method of service returned by IBinder?

Thank you, kind sir! Your tutorials are very helpful!!!

I'm developing a simple SMS app where we click on button and the messages sent on those phone numbers which are store in DB. My problem is when I send messages to 10 contacts it store in my inbox as single contact like 123456789, 123456789, 123456789 but I want when I send messages to 10 contacts it stores in my inbox like group where all contacts show in group. Can u please tell me hoe to do it ?

Thank You sir, it is very helpful.

but this is from same application. thus we are able to see the toast on the app. it didn't send any data back to the activity. just created a toast on the server application.

If there were to be two apps, then the server app would have shown the toast. the reciver app sends a message thats fine. but nothing is returned back.
