Android : Pausing Game On Pop-ups
Oct 7, 2010I am working on an application and I want to be able to detect when a pop-up (e.g Charger notification, task switcher or the dialog that pops up when you hold the power button) is obscuring the game so that I can bring up the pause menu. These notifications do not produce an "onPause" event. Does anyone know the correct way to do this? I know it can be done by detecting the focus loss from the surfaceview, however views can be added and removed I was wondering if there is a better way of doing this than adding a focus handler to each one and trying to keep track.

Aug 13, 2010In my game when the user completes a stage, I want the main game thread to pause/sleep/wait and a new activity to be launched called StageClear that displays information about points scored etc. After this has been displayed and the user has pressed continue I want the original game thread to resume where it left off. I have tried to implement this but have so far been unsuccessful, probably because I'm new to dealing with multiple threads and also the idea of synchronizing them. I most recently tried to implement a shared package-visible object that could notify after wait was called on itself, but I am getting errors in eclipse so it won't even compile, I think because though the object is declared public in an inner class, it cannot be seen or recognised by my activity elsewhere in a file in the package. I have already built both activities but my issue is getting the main game one to launch the other, and pause whilst it waits for this activity to finish, before the main game thread continues execution.

Apr 7, 2010I'm having some difficulty figuring out the best ways to pause and resume my application. Is there any comprehensive tutorial or something similar that would help me make sure that I'm not missing any important steps?Mostly I'm just worried about not dealing with the memory being used by my application. There's a few apps I own that when you minimize them slow down the rest of the phone to a stand still and I want to make sure to avoid that.
View 1 Replies View RelatedAndroid :: Pausing A Thread - Activity Pause Timeout For HistoryRecord
Jun 30, 2010I'm trying to write a game engine in Android, but I don't have much familiarity with threads.
My thread has an attribute, mSurfaceHolder, which holds the surface that I'll be drawing to. The run() method for my thread looks like this:
CODE:.............
STATE_RUNNING represents the state when the activity is in the foreground and the game should be running.
STATE_PAUSED represents the state when another activity has come into the foreground. I'm not completely sure why I need to still draw while it's paused, but that's what I seem to have gathered from the LunarLander example.
What I'm hoping is that while I'm looking at the activity, the game will update and draw (which I test by using LogCat). And then when I go back to the home screen or another activity appears over the top, it will just draw.
Well it does draw and update while I'm watching the activity, so the game loop itself works. But when I leave the activity, it has no effect. Here is the thread's pause() method that is called from the activity's onPause():
CODE:.............
As you can see, to test this method I have logged some messages. Now what I find when I leave the activity is that "Here" is logged, but "There" is not. Now with my limited knowledge of threads (I hardly know what synchronized actually does), I believe this will happen because my thread can't get synchronized with the surface holder. But I don't know WHY it doesn't synchronize. A few seconds after I've left the activity, I see the following warning in LogCat:
Activity pause timeout for HistoryRecord
Any idea why this would happen? There are no problems if I try to start the activity again, the thread just keeps running as it was.
Just discovered something else. The thread pauses just fine if I leave the activity within about a second of having started it. And then it will resume and pause again with no problems at all while the same task is still running. I have no idea why for a short period of time it will work, but if I leave it too long, it won't.
Okay... I fixed it. But I don't think I'm supposed to do what I've done. I've basically removed any synchronization with mSurfaceHolder from both the pause() and the setState() methods (which is used by pause()). No it works as it's supposed to, but I'm thinking the synchronization is there for a reason.
Perhaps the best question for me to ask is this: WHEN should you synchronize a thread with an object by use of a synchronized block? And in this case, what is the purpose of synchronizing with the SurfaceHolder?
Android :: Pausing / Stopping And Starting / Resuming Java TimerTask Continuously?
Jan 20, 2010I have one simple question regarding Java TimerTask. How do I pause/resume two TimerTask tasks based on a certain condition? For example I have two timers that run between each other. When a certain condition has been met inside the task of first timer, the first timer stops and starts the second timer, and the same thing happens when a certain condition has been met inside the task of second timer.how do I pause timer1 while running timer2 and vice versa while timer2 is running? Performance and timing is my main concern as this needs to be implemented inside another running thread. By the way I am trying to implement these concurrent timers on Android.

Jul 23, 2009I have an activity that is showing a video and when the user clicks a button, a new activity is launched. When the video activity stops, I pause the video view. When the video activity starts up again, I try to resume the video view videoView.start(), however, the video starts over from the beginning. I'm thinking that the buffer must be lost somewhere, so I now try to capture the current position via videoView.getCurrentPosition(), however, this is always returning 0.
Anybody know how to resume video playback when an activity starts up again?

May 22, 2010I have a square grid, for a turn based game ( grid is similar to the chess board ), but the moves in the games are different based on whether you have lapped your opponent pawn at least once or not.i.e if you have not lapped (beaten any of the opponents pawns) in the outer most grid as below.if you have lapped your opponent pawn once at least, then you get to reach home,this way.Any player having all his pawns reaching "home" first wins.The ones in yellow are safe-houses, i.e both the opponent pawn and the player's pawn get to stay in the same grid, this is not considered to be lapping ( the opponent ).The lapped pawn will return to its start point.Now the question is, what is the effective way to store the paths for the all the pawns.we will have 4 pawns for the player and 4 opponent pawns.Is there any pattern to store such static information, in a elegant way?

Aug 11, 2009I've followed the excellent article on game development here: http://www.rbgrn.net/content/54-getting-started-android-game-development, and started my game based on the Lunar Lander example. The Lander example re-draws the background and everything else on each "tick". I basically followed its example and I'm using my game's background image to essentially "clear" the canvas so that I can re-draw everything from a clean slate. This, as I've found, has a negative impact on performance as my game is beginning to slow down. My question is, what's the best way to optimize this? If I want to "clear" only certain parts of my canvas, how do I do that? I've read the documentation for android.graphics.Canvas, but am getting confused by a lot of jargon I don't understand such as "clip" and "matrix".
