If the data you want to send between devices is event driven (e.g. Sadly it seems that you can't use datagrams with Bluetooth on Android, therefore you have to stick with TCP. If I'm correctly reading between lines from your comments, you could really use a Bluetooth UDP socket. Implement a timeout in BluetoothSocket inputstream.read() in Android System.To check if there is data in the stream before reading without blocking, and check for the elapsed time between reads to decide if a timeout occurred (System.getCurrentTimeMillis() should do the job).Ĭheck this answer for reference and a complete listing:
timer.cancel() //Not necessary because we call System.exit
FOR LOOP AS TIMER JAVA CODE
You want to use code snippets! Also note that the RemindTask class isĭefined internal to the AnnoyingBeep class, something legal in Java. Note that on the Sun site this code is presented without the importsĪnd without a main() method to create the task. The first is an example of using a timer to perform a task once per second. Though those are the links to read, below I've put a few tiny pieces ofĬode to demonstrate a bit about how timers work.
The other is about the Swing-based timer,. These are event-based and can be used to control tasks such as animations. Java has two types of timers both of which are well explained on Sun's website. This example from the Java Developers Almanac 1.4 shows. Simple knowing the current time in order to compute elapsed times Started 1 July 2003 September 2005 - some of the links below need fixing.
