[android-developers] Re: What's the best way to have your app 'sleep' for N milliseconds?
Inside your MyActivity.onCreate method:
Handler timeoutHandler = new Handler()
{
//@Override
public void handleMessage( Message msg )
{
// after receiving the timeout message, start the next activity
Intent intent = new Intent( MyActivity.this,
MyOtherActivity.class );
startActivity( intent );
// terminate this activity if you don't want to leave it on the
activity stack:
MyActivity.this.finish();
super.handleMessage( msg );
}
};
Message msg = new Message();
timeoutHandler.sendMessageDelayed( msg, 6 ); // milliseconds

Thread.sleep ( 1000 ) will make the app pause for AT LEAST 1 sec. Not exactly 1 sec. Thread is not guaranteed.

You are right:
private static final int WAKE_UP_DELAY = 5000;
private static final int WAKE_UP_CALL = 0;
private Handler handler;
handler = new Handler(new Handler.Callback() {
@Override
public boolean handleMessage(Message msg) {
if (msg.what==WAKE_UP_CALL) {
// change message, your code goes here...
handler.sendMessageDelayed(handler.obtainMessage(WAKE_UP_CALL),
WAKE_UP_DELAY);
return true;
}
return false;
}
}
);
handler.sendMessageDelayed(handler.obtainMessage(WAKE_UP_CALL),
WAKE_UP_DELAY);
// do something...

[android-developers] Re: What's the best way to have your app 'sleep' for N milliseconds?
The Thread.sleep(1000) is probably not the best idea on Android
because responsiveness is an issue if you care about user ratings ;-).
With Thread.sleep() the app just sit's there and waits and won't
respond to user input.
I would recommend using something like:
private static final int WAKE_UP_DELAY = 5000;
private static final int WAKE_UP_CALL = 0;
private Handler handler;
private Runnable wakeUpCall = new Runnable() {
@Override
public void run() {
handler.sendEmptyMessage(WAKE_UP_CALL);
}
};
handler = new Handler(new Handler.Callback() {
@Override
public boolean handleMessage(Message msg) {
if (msg.what==WAKE_UP_CALL) {
// change message, your code goes here...
// let's start the timer again
handler.postDelayed(wakeUpCall, WAKE_UP_DELAY);
return true;
}
return false;
}
}
);
handler.postDelayed(wakeUpCall, WAKE_UP_DELAY);
// do something...
The // do something part is the important difference to the
Thread.sleep(). With the latter the app sleeps while with the my
version the app can do whatever the app is supposed to do.
And after a certain time (5 seconds in my example) you can change the
message or whatever else there is to do.

Whatever the case is, you cannor prevent the user to press the Home
key to display the Homescreen, right? If you don't care about the Home
button, then I guess, an Activity or a dialog should be fine.
