I am rotating a view using rotateAnimation with this code new RotateAnimation(0, 360, w / 2, h / 2); I want to rotate this view infinitely, so i put setRepeatCount(RotateAnimation.INFINITE);
But the problem is after every one complete rotation, its stopping and starting again, means by default rotateAnimation have AccelerateDecelerateInterpolator(). I feel because of this. So if i put setInterpolator(null), its throwing null pointer exception. How to solve this.
I want to rotate my view without any lag.
To support usability studies on what applications are used, i want to write a service that logs when an activity is started and also when it has finished. This is to understand how the users are using the device:
One straightforward option is to have the applications modify, to write this out. But this is tedious having to modify all applications and will not work esp with third party or built in applications.
Is there any alternatives that makes this simpler and easier?
BTW: Looking at the android framework source ActivityManagerNative seems to be invoking a Binder interface when an Activity is started and finished. Any information on what this service is? Is this something i can tap into?
I have a Service which tracks the location of the user. Currently, the Service boots when the application starts and stops when the application terminates. Unfortunately, if users keep the application in the background, the Service never stops and drains battery.
I would like the Service to stop when my application is not in the foreground. I was hoping the Application class would let me Override onPause and onResume handlers, but it does not have them.
I 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.
View 4 Replies View RelatedI'm writing a game using the drawing method from Chris Pruett's opengl spritemethodtest demo. The Activity running my opengl view works fine on initial load, and about half the time after turning off the phone and turning it back on. However, the other half, it locks up. I'll get a "lock_layer timed out (is the CPU pegged?)" warning that keeps repeating. I tried running the debugger to find the exact line that the error is occurring on, but the strange thing is that this error won't occur if I'm running the debugger on my G1. It only happens under normal operating conditions. Any help would be appreciated, as this bug really has me stumped.
Here are my onPause and onResume activity methods:

I have an Acer A100 tablet that I've upgraded to ICS (the upgrade went very smoothly, by the way). But under both ICS and the original Honeycomb, the Android OS has an annoying habit of starting a bunch of apps automatically. Facebook, Google Maps, media players and a whole host of apps that I do NOT want to start all by themselves. I found an "Advanced Task Manager" that will check every 5 minutes and kill unwanted apps automatically. But every time I check it there are still half a dozen apps running in the background that I don't want.
If it were just one or two apps, I would simply uninstall them. But it seems like half the factory apps are intent on restarting themselves no matter how many times they're turned off. My Acer has a very small battery, and I suspect I'd get much better battery life if it would only run the apps that I start manually.
Other than email and the system update manager, I really don't want any apps running in the background. And when I turn an app off, I want it to stay off until I restart it. Is there a way to edit the list of programs that start automatically? Do they all have to be disabled individually? I've checked a few of the apps, and don't see any way to disable the "automatic log-in", "check for new data" or whatever each program might call it's annoying insistence on starting whenever it wants to.
If I create a no-gui application that extends and android.app.Service class, how do I get it to register itself so that the application starts when the phone boots up?
I need some way to have it always launch when the phone is turned on, how can I do this?
I know how to get a service to start & communicate with a real application, but I can't get it to start when the phone boots.
I have an app which will start multiple separate services which perform an action and then exit. I don't want them all to run at the same time (because this may bog down the OS).
I have the code for finding the services and starting the services, but does anyone know how I can make sure one service has completed before the next starts.
Due to what the app does it will have to start multiple services and the actions the services perform have no GUI and may take tens of seconds or minutes (hence why I'm using a service so the user isn't just shown a blank screen every time the next service starts).
I am developing an android game right now, and it requires very precise timing and synchronization. That said, it is essential that there is no lag during the game. However I sometimes get lag spikes in the game, and I know its not the GC because I have run the ddms tool, and eliminated all the GC calls. However, I do see alot of background services popping up in my ddms logcat. Is there anyway to pause all services when my game is running?

View 1 Replies View RelatedI have a AppWidget, after I delete it from HomeScreen it seems not stopping the AlarmManager attached with it. I have supported it with the AlarmManger, that call the ProviderImplementation class every 1 minute and in onReceive I put the code to call onUpdate. and in onDelete I explicitly stop the alarm, but it seems it is running continously and not stopping. any cure of it ?
I have stopped it with cancel(pendingintent) function.
My appWidget is working well. When it's installed and used by user, a Thread is launched to refresh view (like a flipper). Even if the screen is off, the thread is continuing...perfect for me... But after 3 minutes, it's stopped.
Does it a VM restriction avoiding some bad development usage?
How can I use this type of service? Develop a service in place of my thread?
can someone help me.. i want my service to start as soon as the device starts and also the service to persis and remain started.it should destroy only when device switches off.

It would speed up our testing process so much. Right now we uninstall/install the app each time to make sure the manual test cases start with a clean state.
My service spawns a new thread, and stops it according to the typically recommended java method of interrupt()'ing. When I stop the service, I stop the thread in onDestroy(). The service is stopped, and the interrupt code is reached. However, soon enough the thread restarts from the beginning of the Runnable.code...

View 4 Replies View RelatedThe Content Provider starts when the first applicable URI is resolved. This will make the ContentProvider run forever and there doesn't seem to be a way to stop it (such as due to inactivity etc).It would be nice if Content Provider would stop after some time so that the memory usage is reduced (An enclosing process, doesn't need to be alive if the Content Provider is not needed anymore).

When the widget is deleted (onDisabled()), I call .cancel() on the service, but the service still shows up in the android "running processes" making me believe I'm doing something wrong.Also, should I be scheduling my updates in the onEnabled() or the onUpdate()? onUpdate doesn't seem to work on anything other than the first widget.

I have this problem, I have some audio I wish to play. And I have two buttons for it, 'Play' and 'Stop'.Problem is, after I press the stop button, and then press the Play button, nothing happens. -The stop button stops the song, but I want the Play button to play the song again (from the start) Here is my code:final MediaPlayer mp = MediaPlayer.create(this, R.raw.megadeth);And then the two public onclicks: For playing)
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
button.setText("Playing!");
try {
mp.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
And for stopping the track
final Button button2 = (Button) findViewById(R.id.cancel);
button2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
mp.stop();
mp.reset();
Can anyone see the problem with this? If so could you please fix it. (For suggest)
How can I identify and stop single running services? More specifically, once I got the running services on a List as in a chunk of code like:
ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE); List<RunningServiceInfo> services = activityManager.getRunningServices(Integer.MAX_VALUE);
Is there any method to stop a single service, i.e to identify one and then stop it?
I'm trying to prevent my application to call the same method twice in the event of a double-click, or if the user presses different buttons quickly, almost at the same time.I have clickable Views, acting as buttons, that call the same method but passing different parameters.Inside this method I'm creating a new Thread, because it queries a web server for the result.The problem is that upon two quick clicks, the method is fired twice, two threads are created, and consequently two new activities are created. That makes my app crash.But this only seems to work on slower phones like the G1, I tried on Nexus and before it set blocked = true, the second request has was granted. So is there any way I can block the method being called if it's already running, or if the thread has started so it wont create a new one.

View 1 Replies View RelatedIn my game, I've got one activity starting another activity via an intent. When the user is finished with the second activity, they quit it using the back button. However, I have a problem: when this happens, the second activity is still running, even if it's quit with the back button.
My second activity will eventually give a "game over" message using a pop up window if there is no user input for a period of time. Problem is, when I back out of the second activity (where the game is happening) the "game over" message still appears eventually. This is how I know the second activity is still running. It even displays a "game over" message if my entire app is quit (on the Android OS).
How do I stop an activity completely when the user presses the back button?
My application uses GPS updates while it is running and I would like that to stop when the user back out of the app as I assume it will continue wasting a lot of battery power. I've tried intercepting the back button press but it doesn't seem to work. I'm not sure if this is because it's not executing the code or I'm using the wrong command.
