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...

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?
I am facing a problem with a stopping thread which is in a synchronized block. I am using TCP socket. The problem is that I am waiting on a DataInputStream object and I want to create a new socket again but it doesn't allow me to do because of the synchronized block.
I have tried with Thread.interrupted(). I cannot avoid the synchronized block. Is there any other way to do the same?
dis = new DataInputStream(ReadWriteData.kkSocket.getInputStream());
int i = -1;
String aval = ""; //new String();
char c = (char)dis.read();
It is getting blocked on dis.read().
What I should do for escaping the dis.read when I want to create a new socket?
How can I implement a run() method of thread if I create a Thread Global?
I mean If I create a Thread Globally then can I implement its run() method {" public void run()"} anywhere in my Application?
In the run() method I have to write the code to perform some action.
IF I can do it then please can anyone show me briefly how to do it particularly.
I am writing an application in which i need to handle messages between the main thread(the deafult UI related thread) and the user created Gamethread.
The requirement is like this.
An activity(say "Activity_X") is setting the view by "setContentView(some "View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for creating menus & a switch case for action to be taken on selecting those menus.Menu has items like "resume/pause/zoom/" .
All action to be take on selecting these menus are implemented in "View_Y" in a separate Gamethread by extending "Thread" class.
So whenever a menu is selected in "Activity_X" i need to send a message to "View_Y". And on receiving this ,a particular action/method should be called in View_Y(GameThread).
How can i achieve this using Handlers?Is there any other way of doing this? Please do share with me some code snippets for these.
I have a separate thread running to get data from the internet. After that, I would like to update the ListView in the main thread by calling adapter.notifyDataSetChanged(). But it does not work. Any workaround for that?

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 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.
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.

I'm trying to help someone who'd like a way to stop email spam from reaching his Android phone. I understand this is usually best done from the email server side of things, but this is where we are right now. This is regarding his work email, and I've suggested that he have gmail fetch it for him so they can filter it (does this work for fetching? I know it works great for emails sent directly to gmail), alas, he says he only has an imap server and no Pop3 server for gmail to fetch. I looked in the market and found only one not terribly highly rated app for filtering email spam on Android phones. If you've tried that email filtering app, it worked?
