Android :: Generic Task Manager Class For Application / No Dismiss Dialog

Nov 15, 2010

I have a class which extends AsyncTask, which is intended to serve as a generic task manager class for my application. The strange behavior is that the progress dialog shows up, but is never dismissed. I am sure that onPostExecute() gets called for every task instance, as any Log.d("","") statements fire if placed in here, even the Toast messages show up from within this method, but I am not able to dismiss the static dialog. I understand that AsyncTask(s) have access to UI thread at only 2 places [onPreExecute() and onPostExecute()], so I think trying to dismiss the dialog in runOnUiThread() is unnecessary. All calls to executeTask() are made from different onCreate() methods of different activities that need to fetch some data over network before populating some of their UI elements, and I always pass the current activity's context to the tasks. As I do not switch activities until after the related tasks are completed, I believe the activity context objects are still valid (am I wrong to have assumed this???) I have never found any of them to be null while debugging.

Could this be a timing issue? I have also observed that most of the times DDMS shows all tasks get completed before the activity is displayed. If I use new Handler().postDelayed(runnable_which_calls_these_tasks,10); in the onCreate(), and add delaying code in foo_X(), the activities are displayed without any delay, but the dialog will just not dismiss(). I have read through quite a number of articles on this issue but am still not able to figure out exactly where am I going wrong. I do not want to define each task as private inner class Task1 extends AsyncTask<> in all of my activity classes and I would not want to (unless this is the only solution) load my application object with all activity references either as mentioned in this discussion: Is AsyncTask really massively flawed or am I just missing something?. I have spent a week on this and am absolutely clueless :( It would be great if someone can guide me, and let me know what am I missing. Following is the class definition: [I've removed some irrelevant application specific code for clarity]

public class NetworkTask extends AsyncTask<Void, Integer, Boolean> {
private Context UIcontext;
private int operationType;
private static ProgressDialog dialog;
private static int taskCount;
private NetworkTask(int operationType Context context){ this.UIcontext = context;
this.operationType = operationType;
if (taskCount++ == 0) dialog = ProgressDialog.show(context,"","Loading...");
}

public static Boolean executeTask(int operationType, Context context) { return new NetworkTask(operationType, context).execute().get();
} @Override protected void onPreExecute(){ super.onPreExecute();
if (taskCount == 1) dialog.show();
} @Override protected Boolean doInBackground(Void... arg0) { switch(operationType){ case TYPE_1: foo1();
break; case TYPE_2: foo2(); break;
case TYPE_3 foo3(); break; case TYPE_4: foo4(); break;
} @Override protected void onPostExecute(Boolean result) { super.onPostExecute(result);
taskCount--;
if (dialog.isShowing() && taskCount == 0){ dialog.dismiss();
}else { Toast.makeText(UIcontext, "Task#"+ operationType+", m done, but there are "+taskCount+" more", 5).show();
} } }

HTC EVO 4G :: Anyone Recommend Task Manager Application?

Jun 12, 2010

I am totally new to the android thing and the evo is my first ever droid based phone. I installed something called advanced task manager from the marketplace however I am finding several threads on how its not a good thing for the phone. I have no idea if its good or bad, but I do know that what shows up in the task manager list of running apps is way different than what shows up in the phones running task list - menu/settings/applications/running services. What shows up in task manager is a bunch of stuff that running services don't show. So whats the scoop? To have or not to have?

Android :: Right Way To Dismiss Dialog

Dec 17, 2009

I am trying to use a managed dialog. I noticed that after the first time I display it, subsequent creations don't actually make a new instance of the dialog, they just seem to reuse the first one. If I want to stop that, and get a brand new instance on every call, is this the right way to do it?:

@Override
protected Dialog onCreateDialog(int id) { switch (id) { case MY_DIALOG_ID:
MyDlg dlg = new MyDlg(this);
dlg.setOnDismissListener(new OnDismissListener() {
public void onDismiss(DialogInterface dialog) {
removeDialog(MY_DIALOG_ID);
} } );
return dlg;
} return null;
}

So I guess the removeDialog() call does the trick, but my onDismiss() handler should be called in every instance of the dialog being killed, right (like Dialog.cancel(), Dialog.dismiss(), hitting the back key)?

Android :: Dismiss Failed In Dialog

Aug 12, 2010

I would like to create my own DateTimePicker Dialog. Therefor I build a layout that I use in my Dialog. My Dialog starts when I click on a Button. When the Dialog opens you can set date and time data. There is still a Button to close the Dialog. This Button calls Dialog.dismiss(). But it fails. Here is some code. Can someone tell me, what I do wrong?

public class CreateActivity extends Activity{ private TextView mDateTimeDisplay;
private Dialog dateTimePicker;
private int mYear; private int mMonth; private int mDay; private int mHour; private int mMinute;
static final int DATE_DIALOG_ID = 0;
@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(de.android.todo.R.layout.create);
//http://babukuma.com/2010/01/android-custom-component- datetimepicker_29.html
mDateTimeDisplay = (TextView) findViewById(R.id.dateTimeDisplay);
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR); mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH); mHour = c.get(Calendar.HOUR_OF_DAY);
mMinute = c.get(Calendar.MINUTE); dateTimePicker = new Dialog(this);
dateTimePicker.setContentView(R.layout.datetimepicker);
dateTimePicker.setTitle("DateTimePicker");
dateTimePicker.setCancelable(true);
DatePicker dp = (DatePicker) dateTimePicker.findViewById(R.id.datePicker);
dp.init(mYear, mMonth, mMonth, onDateChangedListener);
TimePicker tp = (TimePicker) dateTimePicker.findViewById(R.id.timePicker);
tp.setIs24HourView(true);
tp.setOnTimeChangedListener(onTimeChangedListener);
// display the current date updateDisplay();
} public void onClickShowMyDialog(final View v){ showDialog(DATE_DIALOG_ID);
} public void onClickCloseDialog(final View v){ dateTimePicker.dismiss();
} @Override protected Dialog onCreateDialog(int id) { switch (id) {
case DATE_DIALOG_ID: return dateTimePicker;
} return null;

Android :: How To Dismiss Custom Dialog?

May 13, 2010

I'm trying to make a custom dialog to show a view in this dialog. This is the Builder code:

//Getting the layout LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_dialog_simple,(ViewGroup) findViewById(R.id.rlDialogSimple));
//Change Text and on click
TextView tvDialogSimple = (TextView) layout.findViewById(R.id.tvDialogSimple);
tvDialogSimple.setText(R.string.avisoComprobar);
Button btDialogSimple = (Button) layout.findViewById(R.id.btDialogSimple);
btDialogSimple.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//Do some stuff
//Here I want to close the dialog
} } );

AlertDialog.Builder builder = new AlertDialog.Builder(AcPanelEditor.this);
builder.setView(layout);
AlertDialog alert = builder.create();
alert.show();

So, I want to dismiss the dialog in the onClick of btDialogSimple. How I can do it? I don't know how to call the dismiss method from inside a onclicklistener. My buttons have a custom layout, so I don't want to make a builder.setPositiveButton.

Android :: How To Dismiss Spinner Dialog Automatically?

Jul 30, 2009

I am sure that everybody can easily recur the problem I am facing. There is a Spinner in the view, which includes a few entries. When I click the Spinner, it pops up a dialog so user can choose an entry. All these are very normal and you can find such things in SDK's API demo. The problem is: when the dialog is still on focus, if you change the phone's orientation, an exception will be thrown. Something like this:

Android :: Unable To Dismiss Progress Dialog

Nov 5, 2010

I've got a progress dialog that I'm unable to dismiss and I can't figure out why. The first time through the code, it shows the dialog and dismisses it perfectly. The second time through it fails to dismiss. There is no error in the logcat and no exceptions are thrown, but the dialog remains on the screen.

If I run the code a third time, while the dialog is on the screen, a window leak exception is shown in the logcat when the code attempts to show the dialog, which is pretty much what you'd expect. The showDialog is called right before I call the execute method of an AsyncTask and the dismissDialog is called in the onPostExecute method of that AsyncTask.

Android :: How To Dismiss Single Select Dialog?

Mar 14, 2009

Thanks for your reminding me of that. JBQ. From the reference of SDK, AlertDialog information as below. I want to create a dialog but I don't want to have any buttons in the dialog, then I hope to dismiss the dialog after i click any item in the dialog, how should I dismiss the dialog? When the user click the "back" button, it will dismiss the dialog. So I need to send the key message in hard code? is there any other way?

public AlertDialog.Builder<http://developer.android.com/reference/android/app/AlertDialog.Builde...>
setSingleChoiceItems (CharSequence[]<http://developer.android.com/reference/java/lang/CharSequence.html>items, int checkedItem, DialogInterface.OnClickListener
<http://developer.android.com/reference/android/content/DialogInterfac...>listener)

Set a list of items to be displayed in the dialog as the content, you will be notified of the selected item via the supplied listener. The list will have a check mark displayed to the right of the text for the checked item. Clicking on an item in the list will not dismiss the dialog. Clicking on a button will dismiss the dialog. Parameters items the items to be displayed. Checked Item specifies which item is checked. If -1 no items are checked. listener notified when an item on the list is clicked. The dialog will not be dismissed when an item is clicked. It will only be dismissed if clicked on a button, if no buttons are supplied it's up to the user to dismiss the dialog.

Android :: Preventing Dialog Auto-Dismiss On Button Click

Mar 20, 2010

Is there any way (the best way) to avoid this happening? I am using a ProgressDialog which has one cancel button. On clicking the cancel button I want to disable the cancel button and change the message to "Canceling...". That bit's easy. Only once the cancellation has been fully processed do I want to dismiss the dialog. The only way I can think of is to use a custom layout but I would rather keep the default dialog look and feel (rather than trying to simulate it with my own code).

Android : Progress Dialog Went Back To First View Called It When Dismiss

Nov 3, 2009

I have a weird problem on progress dialog: I have 2 views: Login View and say, Display View. In Login View, when I click the 'Login' button, a progress dialog is created (new ProgressDialog(...)), shown and stored in a variable 'mProgressDialog'. After login, the dialog is dismissed and some information are displayed in Display View (Login View hides). Now I want to display another progress dialog when 'Update' button is clicked and when the update is done, dismiss the dialog and display new information. So I use: the Display View for a blink and then shows the Login View. I tried to change the view etc. but same problem happens over and over again. So I am thinking it might because one activity can only be assigned to ONE progress dialog and no matter how you re-create it you still get the same progress dialog. And the dialog is linked to a certain view which will be shown automatically when the dialog dismisses.

Android :: How To Return AlertDialogs From A Generic Class

Nov 15, 2010

Within a public class that doesn't extend any other class I'm doing some evaluation stuff and I would like to return a Dialog if something needs to be communicated to the user.

I'm using an AsyncTask to run a method of an instance of this class from the main ui:

CODE:.........

Now, the public Dialog start() method of OnlineActivities.java creates a dialog using the Context that was assigned via it's parameter.

When the Dialog is returned to onPostExecute I receive the following exception

CODE:......................

I suppose I cannot use the context like this. But what would be the alternative? How can I outsource some basic stuff I always need to do, even some general Dialogs? Do I need to use custom intents instead?

Sprint HTC Hero :: Task Panel X - Advanced Task Manager - Causing Errors

Nov 7, 2009

I've been using Task Panel X and Advanced Task manager to kill unneeded tasks and keep memory at a maximum.

Recently, every time I open Task Panel X and then revert back to Home screen I get the HTC logo and then a loading screen while the device sets itself. This happens even if I kill NO tasks.

So my solution was to uninstall Task Panel X and then use just Advanced Task Manager. All the sudden, same result.

Everytime I open either of these apps and then go back to home screen I get a BLACK SCREEN WITH HTC LOGO, THEN A BRIEF (10 SECONDS) LOADING SCREEN. THEN ALL IS NORMAL.

Sprint HTC Hero :: How To Use - Task Manager - Task Killer App

Oct 15, 2009

Looking for a guide on how to use task killer. I had task killer on and deleted it. I think I was killing tasks that were needed to keep certain functions running that I use frequently. If someone would take the time to help me understand how to use one, I think I would be much more successful with it.

example - text messaging just stopped ( werrent receiving them ) . Once I took task killer off, everything started working again.

Anyway, I just wanted for everyone to post their favorite Task Manager/Killer, and why, and if there are any flaws. I personally use Advanced Task Killer Free. It has a simple UI, and the when you select or unselect apps it remebers it so next time you launch the app you can only remove the apps that you usually do, and keep ones that always run. It doesn't slow down or break the system.

Android :: Android - Dismiss Dialog Method Not Working

May 21, 2009

I am using the showDialog and dismissDialog methods to show progress dialogs in my app. Moved from creating the dialog and calling show() on it to using this in order to save state when changing orientation. But when I change the orientation from portrait->landscape->portrait, the dismissDialog no longer dismisses the dialog. The dialog stay there all the time and I need to press the back button for it to disappear.

To overcome this issue, I tried adding a removeDialog in onDestroy so that the dialog is not created/displayed twice and before orientation change, the dialog is removed. Tried adding log statements and see what happens:

05-21 12:35:14.064: DEBUG/MyClass(193): callingShowDialog
05-21 12:35:14.064: DEBUG/MyClass(193): onCreareDialog
05-21 12:35:15.385: DEBUG/MyClass(193): onSaveInstanceState
05-21 12:35:15.415: DEBUG/MyClass(193): onDestroy

05-21 12:35:15.585: DEBUG/MyClass(193): callingShowDialog
05-21 12:35:15.585: DEBUG/MyClass(193): onCreareDialog
05-21 12:35:15.715: DEBUG/MyClass(193): onCreareDialog
05-21 12:35:17.214: DEBUG/MyClass(193): onSaveInstanceState
05-21 12:35:17.214: DEBUG/MyClass(193): onDestroy
05-21 12:35:17.275: ERROR/WindowManager(193): android.view.WindowLeaked: Activity com.android.MyClass has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@43362088 that was originally added here
05-21 12:35:17.395: DEBUG/MyClass(193): callingShowDialog
05-21 12:35:17.395: DEBUG/MyClass(193): onCreareDialog
05-21 12:35:17.475: DEBUG/MyClass(193): onCreareDialog

If we see here, initially when the activity is displayed, the onCreateDialog is called once and on changing the orientation, onSaveInstanceState and onDestroy are called. But after that, onCreateDialog is called twice (once by a call to showDialog which I make, but why the 2nd time?) and this happens every time I change the orientation hence forth.

Android :: Dialog Dismiss / Cancel Handling (Android)

Nov 19, 2009

I never look forward to handling Android dialogs, maybe someone can point me to a better way of doing it than i'm doing right now. Say I have a dialog which has one text field in it, and OK and Cancel buttons. i make the dialog with AlertDialog.Builder, and set click listeners on the buttons and dismiss listener on the dialog. When the dismiss listener fires, can I tell which button caused the dismiss?

I don't see how, so in the click listener, I set a member flag according to which button was clicked. Then in the dismiss listener, I then check the flag to see whether to proceed or not. Arather backward process. Am I missing something? The other issue I have with Android's dialogs is that if the contents fail validation and the dialog needs to be re-presented, I have to re-show it in the dismiss listener. In every other environment known to man, dialogs are (somewhat) modal, so the dialog stays up unless expressly dismissed by code. IMHO, the latter makes more sense.

Android :: Dismiss Android Preferences Dialog On Keyboard

Mar 15, 2010

I would like to be able to close the editpreference dialog (as shown here http://twitpic.com/18ttdp) by pressing the 'Done' button on the keyboard. Currently, pressing 'Done' just dismisses the keyboard but leaves the dialog. In other parts of my application I use code similar to the following to intercept the 'Done' key press and execute actions in my activity:

text.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override public boolean onEditorAction(TextView v, int actionId, KeyEvent event)
if (actionId == EditorInfo.IME_ACTION_DONE) {
//do stuff here return true;
} return false;
} } );

However, I am unsure of how to do achieve this same effect in my preference activity or layout XML.
