Android :: Activity Pause Rather Than Finish?
Nov 30, 2009I see no means by which my activity can pop itself off the activity stack to return the user to the one he was using before it was invoked. Is there one? My purpose is that my app has some data structures built from data provider queries that take 5-15 seconds to assemble and I don't want a lot of latency if it is used in a few one-shot purposes in rapid succession. I'm more than willing to let the system ask my app to die, but I'd like to keep warmed and ready otherwise.

Android :: How To Close Fore Ground Activity From Active Activity?
Sep 28, 2009I created an application which is asynchronously communicating with the server. When the application makes a server request a new dialog (activity) with "loading" notification is created. The main activity implements methods for handling server responses and I would like to close the foreground activity when the main activity receives the answer from the server.
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 :: Pause Flash Content In WebView When Activity Isn't Visible?
Aug 7, 2010I am experimenting with using a WebView to display Flash content inside my activity. Everything is working pretty well, but when the user hits the home key to put the activity into the background, the Flash content keeps running (sound keeps playing, etc)
I have noticed that both the stock Android browser and Dolphin Browser seem to avoid this problem, and properly pause the Flash content when the browsing activity is put into the background.
Ideally I would like a solution that kills the WebView completely if the activity is finishing, but pauses it otherwise (basically copying the default behavior of the browser)
Here is a simple test I put together that loads a game on Kongregate which has some background music:
CODE:..............
I took a look at the latest source for the stock browser, and it seems to be doing something similar (calling pauseTimers/resumeTimers), although I fear the code I have been looking at is out of date, because it is calling functions that don't seem to exist anymore.
I did verify that the call to pauseTimers is working by testing with a simple JavaScript setInterval which updates a counter. Is there something else obvious that I should be trying in regard to Window or View management?
The documentation for the mobile Flash player says:
Flash Player will also automatically pause SWF playback it is not in view or the foreground application, for example when a call is received or alarm goes off, to reduce CPU utilization, battery usage and memory usage.
This seems to be working perfectly in both the stock browser and Dolphin Browser, but not in my app. Any ideas/solutions would be greatly appreciated!
Update: Here is the function we ended up adding to our activity to get this to work. We call it with "onPause" in the activity's onPause function and "onResume" in the activity's onResume function:

I can code everything up to here. But how can I pause for a few seconds and then repopulate the five TextViews with new values, unhide them and make them all white?

May 28, 2012Just bought LG Optimus S which on sale (half price). The browser was working fine at the beginning. Root it and after that my browser kept force to close everytime i open it.
Unroot it back, and do factory reset, and now it is even worse, i cant even go to googleplay (market) or anything to do with internet, it kept showing me this error:
If open browser
The application Browser (process com.android.browser) has stopped unexpectedly. Please try again.
If open Market
The application Market (process com.android.vending) has stopped unexpectedly. Please try again.
As this phone is locked to my provider, i bought some unlock key to unlock, now my phone is unlock but this thing is coming.
I called LG, they offer me for services which will take more around 4 weeks

Android :: Moving Cursor Adapter Cursor Creation To Background Thread
Mar 29, 2010The structure of some of my activities is a simple ListView with a custom CursorAdapter. The cursor is created in onCreate() on the activity from a SQLite database. The problem is that querying the SQLite database can be quite slow at times with lots of data (and let's assume I've already optimized the sql query as much as possible). Because it occurs in onCreate() on the UI thread, I get ugly black screens when opening the activity, which sometimes turn into ANRs, on a slow phone like the G1. I want to load the cursor in a background and show "Loading.." on screen while doing so. I saw AsyncQueryHandler used extensively in the framework, but this seems a solution geared more towards Content Providers and not application-local SQLite databases. I then thought of trying to load the cursor in a background thread, but realize that this might be problematic, as the CursorAdapter should be instantiated in onCreate() and should take a cursor as a parameter. The latest thought I had was to instantiate an empty MatrixCursor in onCreate() and pass that to the cursor adapter, while kicking off a thread/TimerTask to query the database. Then, on database cursor load, call cursorAdapter.change Cursor to the properly filled cursor. This doesn't seem very elegant and seems quite wasteful, however.
View 10 Replies View RelatedAndroid :: Finish() Won't Close Activity
Jul 23, 2009I have an EditText field and I want to pop up a new window/activity whenever a user touches/clicks the field. The new window has some widgets and of course Apply and Cancel buttons. Here is the code how I intercept the onTouch event.
EditText ctlMaskEt = (EditText)findViewById(R.id.mask_field); ctlMaskEt.setOnTouchListener(new OnTouchListener() { public boolean onTouch (View v, MotionEvent event) { popMaskEditor(); return true; } });
Everythings work fine until I click the Apply and Cancel buttons. The API finish() won't close the new window unless I click the same button one more time. Calling popMaskEditor() from a button's OnClick event handler doesn't have this problem.
