For some reason, one activity (launched in a new process) often takes longer than 10 seconds to start, which exceeds the LAUCH_TIMEOUT defined in ActivityManagerService.How do I make the VM tolerate longer launch time without giving up wake lock?

I would like to keep the screen timeout set to the default 30 seconds to save battery while the phone is not charging. However, I'd like to increase that to at least several minutes while the phone is charging. I don't want the screen to be always on it just doesn't seem like the best thing for the life of the phone. Could be wrong, it just feels that way.Is there any setting or app that would allow this?

In my app I have to load external page into WebView-based activity. Some of my users with slower connections are reporting screen timeout while waiting for the page to load. What would be a good way of loading the page on backgorund thread and then refreshing the screen? Use HttpClient to fetch it and then use WebView#loadData? My fear is - the page I'm loading is pretty complicated there's some JS that happens on load - wouldn't I just mess it up? Is there an alternative way of doing what I need?

Activity B only contains a ListView with CursorAdapter.
Any idea how does this happen? this performance is unacceptable.
I'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?
Is there a way to make the Toast last for longer time? I have tried this code
Toast t = new Toast(this); View v = View.inflate(this, R.toast_layout, null); t.setView(v); t.setDuration(Toast.LENGTH_LONG); t.show(); t.show(); t.show();
By calling show() method more than once, I hoped this would give a similar effect to lasting for longer time with some flickering, but I didn't see any difference. Is there some limit to the number of times that show() method can be called on the same Toast? e.g. just once per toast instance and further calling has no effect?
i have a set of activities on my stack Say A-->B-->C. when i launch the activity named 'D' it should get fired as the root activity of my application and all the other activities(A,B,C) should get cleared from my stack once Activity D is launched.Can any one tell me as how to do this

I have some activities and I have to display a fullscreen ad image before displaying the activity... all my activities extends a custom activity and I thought it was a great idea to implement that advertisement there, so I did: code...
This works nice... the ad is displayed for 3 seconds and it closes automatically. The problem is that the activity that should be hide for the ad is being created faster, so the user can see it for a second before the ad is created. How can I avoid that behavior? How to make sure the ad activity starts before the another does?
I want my activity to appear in the list of activities (gallery. live wallpapers, etc) that you see when you try to choose a wallpaper from the home screen. Im assuming this is done with intents but cant seem to find one that works. The closest one I can find is:

CODE:...............................
I have activities A and B. The A is the one with LAUNCHER intent-filter (i.e. the activity that is started when we click the app icon on home screen). A launches B using start Activity(new Intent(A.this, B.class)). When the user has the B activity open, and then put my application into the background, and later my application's process is killed, when the user starts my application again, B is opened instead of A. This caused a force close in my app, because A is the activity that initializes the resources my app needs, and when B tried to access the uninitialized resources, B crashes.
