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.

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'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'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 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.
code:..............
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:

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 can't seem to grasp why this is happening.
This code:...................
Throws the following exception:
CODE:...........
I'm calling this from the onCreate method.
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've got a quite interesting issue when I try to display a ProgressDialog (the simple, spinner type) within a onPreferenceChange listener.The ProgressDialog shows up, but not until the method (sleep in this case) has finished. What am I doing wrong?

I started two days ago with android, gone through the hello android stuff and also started to read the Hello Android book, which is great.
PROBLEM:
I use in my app - VERY EASY APP- the XML output. So basically the main activity just tells the android to show the XML layout of main.
But what if I have in the activity - code defined integer variable and I want this integer variable also be shown on the display?
How do I PUSH the integer variable to the XML??? From main XML reference to other strings in XML is easy - @string/app_name ... but how do I use the integer variable from the activity?
I have a service that downloads something from the Internet, it shows progress in notifications and in MyActivity (only when MyActivity is on foreground of course). How should the service post the progress to MyActivity? I know this could be done somehow with IBind but can I just simply do this in MyActivity:
MySevice.myActivity = this; startService(new Intent(....));
From MyService I can now call MyActivity's methods because I have a static reference to it in MySevice.myActivity, so I can call e.g. myActivity.sendProgress(63).
In my Android application, I have two activity classes. I have a button on the first one and I want to show the second when it is clicked, but I get an error.

In my activity I have the following code...
I'm experiencing kind of strange behavior of my application after hard Home button is pressed. When you press Home, everything is OK - my app goes to the background, showing Home screen. But if you try to choose my app in the main menu or in the list of last tasks it behaves like it was not started before and does not show the last activity you were on - it just starts from scratch, namely, shows the splash screen and starts next corresponding activities. Moreover, old activities of this app remain on the activities stack, and previous instance of the app is not terminated - so if you press Back for a few times you'll just run into those activities which were undoubtedly started during the previous session of work with my app. Splash screen activity is filtered by "android.intent.action.MAIN" filter and "android.intent.category.LAUNCHER" category. The strange thing is that all of that happens despite the fact that I do not intercept any Back key hits, or override any onPause or onResume methods. What's happening contradicts with my understanding of Android app lifecycle - I was sure that when you hit Home an app just goes to the background, and when you choose it in the menu later - it just unwinds and does not start anew. (Of course, unless stuff like that is stated in the app manifest or corresponding methods are overridden or something else). I also checked it for some other lifecycle events - such as changing orientation or flipping hard keyboard out - and none of those led to such strange results. It appears that the problem occurs when you try to start the app from main menu or menu of last applications.

My question is what do I need to do to ensure there is no resource leak? From the logcat, i see there is a case where it said a window is leaking or something like that.
Can we show the dialog when our application/activity startup?
View 4 Replies View RelatedI have 2 activities, A and B. When A starts, it checks for a condition and if true, it calls startActivityForResult() to start B. B only takes text input so it makes sense for the soft keyboard to automatically pop up when B start. When the activity starts, the EditText already has focus and it ready for input. The problem is that the keyboard never shows up, even with windowSoftInputMode="stateAlwaysVisible" set in the manifest under the <activity> tag for B. I also tried with the value set to stateVisible. Since it doesn't show up automatically, I have to tap the EditText to make it show.
