Android :: ProgressDialog Doesn't Show
May 9, 2010
I'm trying to create a ProgressDialog for an Android-App (just a simple one showing the user that stuff is happening, no buttons or anything) but I can't get it right. I've been through forums and tutorials as well as the Sample-Code that comes with the SDK, but to no avail.
This is what I got:
CODE:..........
I've also tried adding pd.show(); and messed around with the parameter in new ProgressDialog resulting in nothing at all (except errors that the chosen parameter won't work), meaning: the ProgressDialog won't ever show up. The app just keeps running as if I never added the dialog.

I'm writing an Activity which fetches some XML from the web via HTTP and then parses it into a DOM. It then pulls some required data from the DOM.
As you can imagine, this takes a few moments, so I put that code into it's own thread and then tried to set up a ProgressDialog to display while the user is waiting for that to complete.
The problem is that the ProgressDialog doesn't display at all. If I remove the call to dismiss() then it displays after the work is done and, obviously, just sits there...
Here is my code:..................
The constructor of the FighterVersesDownloader is where all the work in terms of HTTP and DOM is done.
Any ideas on what I'm missing? I've seen a few similar threads on this using AsyncTask, but I wanted to use good old fashioned Threads directly and the solutions suggested don't apply.

I try to show a ProgressDialog at the beginning of my application from an Activity. I debug the application and in theory the dialog is created because it prints a line from onCreateDialog... method.
For more test, I try to show a toast with:
Toast.makeText(MyActivity.this, "test", Toast.LENGTH_LONG);
And nothing is showed.
If is useful, the application is a widget.

I'm starting a ProgressDialog using:
ProgressDialog.show(Example.this, " " , " Loading. Please wait ... ", true,true);
Then running a block of code to download and parse XML.
The problem I'm having is that this is all running under a onClick button method, and that the xml is downloaded and parsed before the dialog is shown.

I have a listview of items (songs on the sd card). The user has an option to load all the songs on the sd card to into a current playlist -- those songs are what is displayed in the listview. Because this can take few seconds to load if they have a lot of songs on the card, I want to display a progress dialog to just tell the user "One moment..." until the list refresh is done.
I launch a thread to do this. I've done this successfully on another app I have (which just updates a database in the background but doesn't update any display), but this one fails with this error message, "Can't create handler inside thread that has not called Looper.prepare()". I chopped down the activity and pasted it below. What am I doing wrong here? I have just a vague idea of what might be happening.
By the way, everything works when I take out the threaded stuff, it just looks like the app freezes for a couple seconds.

When i first launch my main intent, i check if the application was updated and, if yes, i decompress some asset files. This task can take up to 15 seconds (to decompress a 6MB zip file).
So, i was trying to show a ProgressDialog to the user. However, nothing in hell makes the dialog appear.
The lengthy method is called from onCreate. I already tried to put it in onStart, but same thing. I also tried to run it in the ui thread, same thing: no dialog appears, even if "isShowing" returns true.
This is the code:.......................

I have some code in my program that processes some stuff, and takes a few seconds. So I thought logically I can place my dialog show at the beginning before processing begins, and cancel it at the end. What ACTUALLY seems to be happening is my dialog shows after the processing is done... Some demo code to show what I mean with a simple sleep:

Im trying to show a ProgressDialog while the activity is loading. my problem is that although i completed all the work in the activity. it takes a long time for the activity to load, i suspect this is because i use
multiple views with multiple listviews with custom array adapters inside a viewflipper. it takes a long time for the UI to show.how would i go about checking that all the UI inside the activity finished loading? or is there a way to preload all the activity and the UI?

I am developing my first Android App and I need a ProgressDialog to be showed while a background task, in this case just a http call on the server, happens.
I did a bit of studying on this and also have already checked other threads related to this subject.
http://developer.android.com/reference/android/os/AsyncTask.html
[url]
[url]
[url]
Among others.
Than I got to write a bit of code:
1) In My Activity I declare a variable to be of type ProgressDialog
code:............
2) I have also written an inner class to extend AsyncTask as required, here in the doInBackGround is where I call a static method which actually do the POST http request to the server, in the server side I have blocked the server response 20s to validate the progress dialog.
code:............
3) When the button is pressed I than build the ProgressDialog anc call the AsyncTask I have created:
code:...................
Well, this is it, I believe this was suppose to show a progress dialog while the AsyncTask would query the server in background, but what I get is NO progress bar until server response arrives and than for a fraction of time(less than 1 second) the progress shows and the next Activity is called.

I know that this is common problem, but still I cannot find the answer. I have two classes: InternetConnection extends Activity ConnectionChangeReceiver extends BroadcastReceiver
From ConnectionChangeReceiver I'm calling InternetConnection method which is refreshing UI when Internet connection is changed. The problem is that during refresh operation I'd like to show ProgressDialog which actually is never visible !!
So broadcast class looks like: public class ConnectionChangeReceiver extends BroadcastReceiver. Code...

ProgressDialog during location tasks either won't show or force closes - I have tried everything!
I now have it in a Handler with a full 1 second delay (one method another post suggested) but it doesn't show. I simply am stuck. Threads are usually force closing when I use those methods.

I have code in my activity's onCreate that sets an onItemClick listener. when it fires I try to show a ProgressDialog that will be up until a subsequent thread "Thread" does it's processing. Strangely to me, the progress dialog never shows until *after* the thread.run() processing is complete. Almost like it's blocking. Am I doing something wrong? this is true even if the run method of doCurrentLocation doesn't do anything.
CODE:.................

I'm using Windows 7 and installed the 64 bit version of Eclipse 3.5.2. I then installed the Android ADT plugin, but when I try to configure it in the Windows > Preferences dialog, the Android Plugin doesn't show up in the left pane. Instead I see DDMS. This prevents me from specifying the location of the Android SDK (unless there is another way) to give me the appropriate templates and such.

My EditText configured as follows won't show the hint code...
It works if I set android:gravity="left" or if I remove android:scrollHorizontally and android:singleLine attributes, which is not desirable.

When I add a new contact to my phone it doesn't show up in the contacts list. When I dial the number manually it shows the name of the person I am calling or that I added. Where is it putting my new contacts? Is there a group setting somewhere I missed?
I also noticed that all my numbers that were brought over from my old phone are listed twice when I go to edit a contact. They are only listed once when I look up a contact but under edit there are two screens with the same info.

We've upgraded yesterday our App (easy.go) on the Android Market and after that we have got several messages from HTC Tattoo and Sony Ericsson XPeria mini users, that they can't see application on Android Market. We are not you using Copy Protection when uploading to the market, so I guess, it couldn't be a problem. The first assumption is that the problem was because of small screens. I took a look in manifest.xml. There is written: Code...

My mom has an HTC Inspire. She uses the stock HTC calendar to access her Calendar, but her google calendar isn't showing up. I have double checked my accounts and Calendar is checked under the sync settings. However, when I go into the HTC calendar, the only calendar available is the PC Sync calendar. When I go into settings, and Calendars, the Google Calendar doesn't show up there either. I have added another google account to the fun just to check and it syncs the account normally.

I have two phones, one running 1.5 and the other on 1.6. When I connect the 1.6 device via usb, DDMS recognizes it and in the top-left pane shows: HT842....... | Online | 1.6, debug
It then lists the individual processes, I can select them and use various tools like allocation tracker.
But when I connect the 1.5 device, DDMS recognizes it but shows: HT95A....... | Online | 1.5
But it does not show any of the processes on the device, so I am not able to do use allocation tracker and such. The sysinfo tab works, and I can monitor logcat with filter and such in the bottom pane.
What am I missing here? Obviously the 1.5 device has USB debugging enabled. Why does it not show 'debug' in DDMS? I'm using SDK 1.5_r2 on linux (Ubuntu 9.04), if that makes a difference.

I have a MapActivity. If it's set to an appropriate location and zoom level to see traffic none is shown after it's first created until you interact with the map (click on it, drag, etc) at which point traffic shows up. Naturally I want traffic to show up without any user interaction after it loads but I've been unable to figure out how to trigger it. Any ideas?
