Michael, I had a look at
http://code.google.com/android/reference/android/os/MessageQueue.IdleHandler.html,
which is supposed to be called when the message queue is empty, but I
never received a call on it. I'm implementing it like this:
myHandler = new Handler() {
MessageQueue.IdleHandler foo = new MessageQueue.IdleHandler() {
public boolean queueIdle() {
//Do something
return true;
}
};
public void handleMessage(Message m) {
//Handle the message
}
};
Am I implementing it right?
@RomainGuy, just using post didn't help, but I think using post()
would be better to use if I was able to check the status of the
message queue (empty or not).
