Basic service example in android

2 votes · 0 comments

Service -A Service is an application component representing either an application's desire to perform a longer-running operation while not interacting with the user or to supply functionality for other applications to use.
Difference between a Thread , service and asynchronous task
1) Service is like an Activity but has no interface. Probably if you want to fetch the weather for example you won't create a blank activity for it, for this you will use a Service.
2) A Thread is a Thread, probably you already know it from other part. You need to know that you cannot update UI from a Thread. You need to use a Handler for this, but read further.
3) An AsyncTask is an intelligent Thread that is advised to be used. Intelligent as it can help with it's methods, and there are two methods that run on UI thread, which is good to update UI components

Using C-style printf format strings to include variables in strings.xml

2 votes · 0 comments

Variables can be included in the strings defined in strings.xml using the C-style printf '%' syntax. This is because getString passes the string through java.util.Formatter.
In the example above, getString substitutes %d for the integer 10 in the string message.
This tip was taken from Bram Borggreve's blog ( bVirtual.nl ).

Convenient messaging between threads

2 votes · 3 comments

The present snippet came up, when I struggled with messaging between different threads. The documentation for the event loop (Looper, Handler and HandlerThread) is not that clear, at least for me. The idea is to use a static thread-safe instance for emitting messages to other components even when they are running in different threads. You can use a simple addressing mechanism or safely broadcast your message to all subscribed components. This could be useful when you are dealing for example with a rendering thread, that needs to communicate with your state machine(s), which in turn needs to broadcast state changes (which was my case).
