[Q] timer keeps going after app has been terminated?

I am making an app that plays sounds in a loop based on a timer. after I exit the program using finish(); the sounds keep playing in background anyway. Any ideas of why this is and how I can fix it (besides having to use a task killer every time)
thanks

finish() just closes the activity, it does *NOT* close the app. Threads will continue to run, services will continue to run, broadcast receivers will continue to receive, etc...
You need to actually stop/cancel the timer if you want it to stop.
I recommend reading this (and then re-reading it again): http://developer.android.com/guide/topics/fundamentals.html and this http://developer.android.com/guide/topics/fundamentals/processes-and-threads.html

The timer probably uses the system timer service, Which calls your sound file again and again.
Stop the timer in the onDestory function of your activity.

how exactly do I stop it?

Take a look at the documentation from google. probably something like .stop(timer)
don't know

heres the code Im using:
// set timer
TimerTask scanTask = null;
final Handler handler = new Handler();
Timer t = new Timer();
scanTask = new TimerTask() {
public void run() {
handler.post(new Runnable() {
public void run() {
// stuff to run goes here
}
}
});
}};
t.schedule(scanTask, 1, 50); // time how often stuff happens
I've tried many ways to kill it but nothing seems to work

Did you try TimerTask .cancel(); ?

yeah I tried that but it gives me an error saying "Cannot make a static reference to the non-static method cancel() from the type TimerTask"

Ok, thank you very much. I had to tweak it a bit but I got it!

LinearLayout Hyperlink

Hello!
First at all, I'm a beginner in android coding, I'm more a graphist with Photoshop as main tool.
A friend has made an app for my themes and is in holidays until september.
Beeing logical and understanding fast, with my friend Google we found the functions/codes I needed. Except one:
I have a horizontal scroll layout showing the apps needed to install the theme. Each app is showed in a linearlayout.
What I would like is make each linearlayout of apps clickable and make them show the app on the playstore when you click on it.
Thanks for reading

I assume you're using Textviews to add line by line the dependencies.. There is a property called autolink or very much like it that makes a link whenever it finds a url in the text...
But instead of Textviews in a linearlayout, why not use ListView? Then you can handle the click in the item to create an intent to open the browser with the url needed... it's a bit of more work but has a better esthetic than a bunch of TextViews... For instance, it makes it easier to use when in a ldpi device...

Sorry for the late.
I'm beginner in java coding so I don't undersand well what you mean dude.
In fact, what I have now is:
In res\layout\main.xml:
Code:
<HorizontalScrollView
android:id="@+id/layout5"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/layout3"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginTop="8dp"
>
<LinearLayout
android:id="@+id/layout4"
android:background="#00000000"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
</LinearLayout>
</HorizontalScrollView>
In MainActivity.java:
Code:
boolean apexInstalled = appInstalledOrNot("com.anddoes.launcher");
RelativeLayout apexApp = (RelativeLayout) getLayoutInflater().inflate(R.layout.item, null);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams((int) (125 * scale + 0.5f),(int) (150 * scale + 0.5f));
ImageView apexI = (ImageView) apexApp.findViewById(R.id.appIcon);
apexI.setBackgroundResource(R.drawable.apexicon);
TextView apexT = (TextView) apexApp.findViewById(R.id.appText);
if(apexInstalled){
apexT.setText(R.string.installe);
apexT.setTextColor(Color.parseColor("#5a925d"));
}
else{
apexT.setText(R.string.nninstalle);
apexT.setTextColor(Color.parseColor("#de3747"));
}
apexT.setTypeface(font);
TextView apexTitle = (TextView) apexApp.findViewById(R.id.appTitle);
apexTitle.setText("Apex Launcher"); // \n == retour a la ligne
apexTitle.setTypeface(font);
apexApp.setBackgroundColor(Color.argb(190, 0, 0, 0));
listApp.addView(apexApp, params);
And I have many blocks like this one but with other apps, and I would like them to point on the playstore, what do I have to add?

Use a ListView with a custom Adapter: http://www.vogella.com/articles/AndroidListView/
Then add an OnItemClickedListener to the ListView.
In its onItemClick method you can use an Intent like this one:
Code:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getActivity().getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(getActivity(), "Google Play is not installed on the device.", Toast.LENGTH_LONG).show();
}

Thanks trying to help me, but I understand aproximatively the intent, but the listview etc, no..
I'm just trying to modify a bit an app somebody made for me using my logic to understand what I have to do. The problem is that I don't understand how to apply what you tell me :/

OK, then let's forget about the ListView if you just want to modify your existing app with as little effort as possible.
Try that in your Java code:
Code:
LinearLayout layout = findViewById(R.id.layout4);
layout.setClickable(true);
layout.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getActivity().getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(getActivity(), "Google Play is not installed on the device.", Toast.LENGTH_LONG).show();
}
}
});
(The word Override has to be written with a capital letter at the beginning. XDA does not allow that.)

But if I understand well that code, it will make a "link case" in the whole scroll layout no?
Or a link for each app?
If it's not possible to cut the horizontal scroll in little squares (links), is that possible to put a hyperlink on each imageview? So that click on the icon shows the store.

Yes, it does. I thought that the Linear layout was loaded as the layout for each app.
Ok. I think that the RelativeLayout in the MainActivity.java is your row, right?
If it is, that should work:
Code:
apexApp.setClickable(true);
apexApp.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getActivity().getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(getActivity(), "Google Play is not installed on the device.", Toast.LENGTH_LONG).show();
}
}
});

Yeah, each RelativeLayout is an app square. I'm not at home so I can't test it now, will later in the evening, thanks for your help!

Hello! I'm in front of a problem.
I wanted to face it alone, but I don't manage it..
I have had a problem with "uri", and after googleing, I've found that I had to import it.
But my problem is that I get that error:
Code:
The method getActivity() is undefined for the type new View.OnClickListener(){}
Any idea?

Ah, you're right. I'm sorry.
I copied the code from one of my fragments. Just delete the getActivity().
So it is:
Code:
apexApp.setClickable(true);
apexApp.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(MainActivtiy.this, "Google Play is not installed on the device.", Toast.LENGTH_LONG).show(); //replace the MainActivity by your Activity
}
}
});

How can I count how many fragments are there in an activity?

Hi guys,
I just want to know if there is some code to get the current number of fragments displayed on the screen.
Reason for this is, I can tell if two different of them overlaps, but I can't tell if they're equal.
I tried getSupportFragmentManager().getFragments().size() but it doesn't work as it seems as getSupportFragmentManager().getFragments() returns null...

Maybe you called the method before the Fragments were created? Or you're using a ViewPager. Code...

Do you mean Fragments that are actually visible to the user or just those that have been created?
Yeah, that should be the right code... However, it doesn't include the Fragments which were added to the ViewPager as they haven't been added to the Activity/FragmentManager.

Maybe it's something with the fragments initialization. How did you run your code?

Did you import the right Fragment from the v4 compatibility lib? Otherwise, you'd have to use getFragmentManager() instead!
Edit: I see, you're using it above as well so it shouldn't be the case, could you try to call fm.getFragments() and see what it returns, where fm is the FragmentManager you already created?

@SimplicityApks It was so before, it still crashes if I use the fm fragment manager.
I add the logcat output for what it's worth:

What's null, fm or mContactsPagerFragment ?

fm.getFragments() does return null... How could that possibly be? I just instantiated them. Maybe I have to wait till they construct heir views?
I jus checked in the Android Developer API and I couldn't find any mention about this method. Eclipse was suggesting it.
I guess it's been deprecated, but even if that is true, why would it completely disappear?
Please someone that doublecheck on this. (I found getFragment (Bundle bundle, String key), no trace of getFragment...)

I just checked and it works if I don't call it from the MainActivity, anyway I've to say the results are not that comfortable. In some cases I've seen some output as scary as # of fragments on the screen is 45
It would be nice to know how this method works though. Without documentation, I can't really make any conclusion here.
Thank you for your help, and please report in this thread if you can find any explanation about the behavior of this method.

listView stop responding after back from webview

HI, Guys,
I am a newbie, now i am developing a google rss reader for practicing. I used listview to display all the news titles. and webview to view the contents. Every time when i am back from webview, it shows this error:
Error: WebView.destroy() called while still attached!
I overwritten the onBackPressed() in webview activity like this like suggested on codeoverflow:
 @override
public void onBackPressed() {
super.onBackPressed();
if (mWebView != null) {
WebView w = mWebView;
w.removeAllViews();
w.destroy();
w = null;
mWebView = null;
}
}
but it doesn't work. everytime it still shows the same error.
meanwhile, when i am back from the webview, the pressing the items in the main listview doesn't redirect me to the webview activity anymore.
Thanks a lot if someone can give me guidance on this.

anyone has similar experience?

I don't know whether the destroy method is needed. However, I recommend to put that code into the onDestroy() method instead of the onBackPressed() method. Might as well solve the problem.

My first reaction is the same as nikwen's - do you need to do this at all ?
If you do, then it sounds as though the error is arising because your WebView is still attached to something at the point you are attempting to destroy it. So before you can destroy it you'll need to call removeView() on whatever the parent is (probably a layout, I guess).

thanks i will try

Thanks. Then i think i should also call the removeView() before i try to destroy it. I will keep trying and let you guys know my update.

anyways you are extending the intent service i guess it does not implement stopService() rather it stops automatically when it has nothing to do[not sure with it please check documentation for IntentService never actually used one of those ]
I guess you need to extend the Service class from package android.app

Actually I am using toast just for debugging.I am learning services. so I might be wrong at places.I made this service to search for files while an indeterminate progress dialog shows in activity till the broadcast of result is received.
I used intentservice because it was supposed to do one work at a time.please suggest me exact ways to use service in my case.I also want to make sure that if activity is paused(minimized) then, when task is completed activity is also started

You can still use an IntentService to do that. To stop it just pass an Intent to it with a boolean extra indicating that you don't want to do anything. You'll need only one more if clause in the onHandleIntent of the service.

That didnt worked I used it like this.
Code:
@Override
protected void onHandleIntent(Intent intent) {
// TODO Auto-generated method stub
String FILENAME=intent.getStringExtra("name");
String FILEPATH=intent.getStringExtra("path");
boolean b=intent.getBooleanExtra("run",false);
while(b){
ArrayList<File> a=getSearchResult(new File(FILEPATH),FILENAME);
publishResults(a);
this.stopSelf();}
}
Code:
final Intent intent = new Intent(getActivity(), SearchService.class);
intent.putExtra("path",fpath);
intent.putExtra("name",a);
intent.putExtra("run",true);
p=new ProgressDialog(getActivity());
p.setCancelable(false);
p.setTitle("Searching Files");
p.setMessage("Please Wait");
p.getWindow().addFlags( WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON );
p.setButton("Cancel", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface p1, int p2)
{
Intent j=new Intent(getActivity(),SearchService.class);
j.putExtra("run",false);
getActivity().stopService(j);
// TODO: Implement this method
}
});
p.show();
getActivity().startService(intent);

First, if you look in the Dokumentation for IntentService, it says that you should not call stopSelf because it is already implemented to do that when there are no intents left. So It really should be easier to use a Service if you want to stop it like that.
If you want to keep using the intent service, I'd instead use a boolean instance variable which is checked in the publishResults method so just let the service do its work, but before it is published in the UI thread check if the dialog was canceled or not. Otherwise because you have two threads you can't be sure when the other thread receives the boolean change.
To me it seems like you could also use an AsyncTask to handle the threading and that class is easily cancelable .

I cannot use Asynctask ,as operation could be long.checking the boolean before publish is good idea.I will try this
