I am doing a test project using robotium. I need to pause excecution of all the remaining code till the progress dialog is closed. Now i am hardcoding the time. But the problem is sometimes progress dialog will not close within that time period.how can i do this?
You can use the waitForDialogToClose(long timeout) method.
Hope this helps.

I have got this code in my Async task to go to a new activity when doInBackgound is completed, but no matter what I do, I always get the window leak error, I have also tried adding delay to the the progress bar, but with no success. Can anyone help me? Thanks
Problem is your Activity is finished and the ProgressDialog is theoretically still "displaying" which is not possible (since the Activity where it is displayed is gone), hence this error occurs. To prevent it remove the Handler around the dialog dismiss then it should work :)
I need to show a yes/no dialog in AsyncTask.onPostExecute() but I keep getting
java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState
when the screen is rotated just before the dialog is shown. I had a similar problem showing dialogs in the onActivityResult but have since moved the dialogs to the
onPostResume() as suggested by other posts but I am unable to solve this one.
Is it possible to show a yes/no dialog in the onpostexecute() without causing exception and without using "commitAllowingStateLoss"?
Your help is much appreciated.
I think you should maintain state of your activity in which you are calling the dialog, because every time when activities orientation changes onCreate() function calls and if you are initiating any AsyncTask in it, then it will execute it again. May be that's why you are facing the problem. Just maintain its state and then check it, hope it will help you.
Just add this code in your manifest file for that activity. Just type landscape or portrait according to your need.
android:screenOrientation="portrait/landscape"
Thank you.
I am creating an app MainActivity that can calculate a report from its database to be shown in ReportActivity. All report calculation is done in ReportActivity.onCreate().
When the user click on MainActivity-s menu "generate report" the menü remains open for 2 secs until ReportActivity.onCreate() has finished and the report becomes visible.
What is the easiest way to give the user some visual feedback?
I already found ProgressDialog onCreate that shows a progressdialog while doing all calculation in an AsyncTask.
I wonder if there is some easier way to give the user some visual feedbak that the menue was successfully clicked and that the device has not crashed.
in ms windows i would use a waitcursor (hour-glass)
I already tried to open a ProgressDialog() in oncreate of the ReportActivity
final ProgressDialog progressDialog = ProgressDialog.show(this, "MY Dialog", "Please wait...");
but it is not shown at all.
Update final solution:
As the answerss suggested I implemented an AsyncTask for the processing following this tutorial
based on this codesample
You need to move your long-running code into a background thread. Long-running code on the UI thread will lock up the UI, which causes the user to think the app is frozen/crashing. Look into using AsyncTask. This allows you to run a process on a background thread and also give visual feedback to let the user know that your app is working.
Design a layout with ProgressDialog. Use setContentView(Progressdialog). Count time for 2-4 seconds (you choice) again set your older layout in setContentView. Why don't you use AsyncTask?
Use a bar or circle activity indicator. From the official design guide:
Activity indicators are for operations of an indeterminate length.
They ask users to wait a moment while something finishes up, without
getting into specifics about what's happening behind the scenes.
I want to set a time (for example 5 seconds) for ProgressDialog in my android app. How can I do this?
I think you can use handler for this.Firstly start show dialog and at this time sendMessageForDelay(event_id,5*1000) and at handleMessage you check dialog is showing or not.If showing you dismiss it.Goodluck :)
I've got a fairly simple issue I'm not sure how to resolve. I want to change the message text of a Progress Dialog while it's running and showing. An example of this would be something like a "time remaining" counter that would count down while the progress animation is spinning. I'm not sure how I would approach this because doing progressDialog.setMessage(String), even within a running thread, will not change anything in the Dialog itself. Thank you!

In short: You need to create a little Runnable which you can execute on the UI thread using runOnUiThread...
