Android :: ProgressDialog In AsyncTask Throws An Exception

Jun 25, 2010

I'm trying to make a simple ProgressDialog appear while my AsyncTask is fetching data. In my onPreExecute() method I have this: pd = ProgressDialog.show(c, "Loading...", "Please wait");

c is the context passed into the constructor of my AsyncTask from this.getApplicationContext(). Unfortunately, I keep getting an exception with this message: Unable to add window -- Token null is not for an application

What am I doing wrong?

Using this instead of this.getApplicationContext() has revealed another problem. When I call ProgressDialog.show(..., a ProgressDialog is displayed, but not until after the AsyncTask has completed. In other words, the data loads and then the dialog is displayed. If I include pd.dismiss() in my onPostExecute() then I never even see the dialog (presumable because it is closed before it ever gets opened).

It turns out that fetch.get() was hogging the UI thread and not letting the ProgressDialog display.

Android :: Calling NotifyDataSetChanged() Throws Exception

Oct 7, 2010

I have a ListView that I'm binding to an adapter. The adapter is a protected member of my main class. I have a listener thread that receives data and updates the source list for my adapter. When I call the adapter's notifyDataSetChanged() method, an exception is thrown:

Runtime Exception: PhoneLayoutInflater(LayoutInflater).inflate(int, ViewGroup, boolean) line: 322

I've read that the notifyDataSetChanged() method has to be called on the UI thread, and I'm doing that. In fact, just to be sure, I even update the ListView's data source on the UI thread. All I do in my listener thread is update a protected member that houses the data. Here's an example of what I'm doing (note that I don't have the part of the code that calls the AsyncTask, but it's fired from a listener):

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

Does anyone have any pointers or ideas as to why I'm getting this exception? Any help is much appreciated.

Here are the layout files, as requested:

main.xml:

Android :: PreferenceScreen - Intent - Element Throws Exception

Sep 17, 2010

I've got a probleme with an exception, but I don't know why I get this exception.

The project is about implementing an AbstractAccountAuthenticator with an AbstractThreadedSyncAdapter to sync certain data on a server with a content provider.

I made everything and both adding accounts and syncing is running without any problems.

Now I've tried to add a Preference-Screen just like suggested in the android reference (search for AbstractAccountAuthenticator, it is explained there) via xml like this:

autenticator.xml:

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

The Preference-Screen-xml looks like this:

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

The screen is promted how it should be, but and that is the problem: When I click on the PreferenceScreen with the intent it leads to a crash of the system (both in the emulator and my HTC-Desire).

Logcat says:

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

Here the part of the manifest, where the activity is defined:

CODE:.......

The whole test-code (it is my project on the essentials to find the problem) is to find at googlecode (http://code.google.com/p/ cleanproject/source/browse/) (Eclipse-Project)

Android :: How To Handle Throws Clause In Java Exception Handling

Sep 4, 2010

I have class A in which I have a method openfileConnec().

It was written like the below:

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

Now I come to class B where I will call this method like the below:

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

I was asked a question in an interview as follows:

Why does the method have a throws Exception in its declaration? Is it that on of the methods called in the implementation throws the base class exception? Also If we get a exception during calling the method (fileConnect( )) control goes to catch block. After executing catch where should the control go, what should be sent to base case?

Android :: Activity - Sometimes - Throws Wrong State Class Exception When Being Resumed After Kill

Nov 24, 2009

I'm testing how my app behaves when killed by the OS due to low memory conditions. I always have three activities on the stack, like: A B C (then C launches maps or some other heavy process)

when my app is killed, and I return to it, C starts itself up again ok. When I hit the back button to go to B, I [sometimes] get an exception thrown which I can't trace. Output is below. I don't know where to go from here. I've only seen one other post mentioning this exception, but it was related to a reproducable error when rotating the device. This only happens sometimes.

Android :: Rotate Bitmap With Canvas.rotate

Sep 24, 2010

As we know, we can rotate a bitmap through 2 ways. The 1st way is: Matrix mt = new Matrix(); mt. postRotate (degree);Bitmap bitmap = CreateBitmap(src, 0, 0, w, h, mt, true); canvs.drawBitmap(bitmap, 0, 0, paint); In this way, we always need create new bitmap for every rotation, it is not good way for high performance game or app.The 2nd way is: canvas.save(); canvas.rotate(degree); canvas.drawBitmap(bitmap, 0, 0, paint); canvas.restore();In this way, we avoid creating new bitmap frequently, but the rotation bitmap is distortion, the bitmap quality is worse than first way.So, Is there 3rd way to rotate bitmap with high performance and good quality? Your any comments are really appreciated!

I am developing one application in which i am getting an exception, and i know this one is the silly or small mistake which i am doing but your help may catch me out and make my day:

CODE:.......

In above code, if i make i=0 or i=1 in tryDemo function then it is running successfully , but if i make it other than 0 or 1 then it throws an exception as "Demo - Demo Exception".

The exception which i am getting, as follows:

Update:- 2
If I remove the "thread" part and wrote the whole function code in the button click event and replaced the "getApplicationContext()" with v.getContext() then it is running successfully.........but i want to implement it within the THREAD.

Nexus :: Rotate 1 Way / Landscape Works / Rotate Other Way / It Doesn't

Jul 1, 2010

I just bought the Nexus One unlocked for AT&T and really like it. 1 wierd thing is that when I rotate the phone counter clockwise, the screen goes to landscape just fine; but when I rotate it clockwise it does not go to landscape "the other way". And, if I'm holding the phone 'normally' and rotate it 180 degrees ('upside down') it doesn't follow.My youngest daughter delights in telling me that her iPhone does this with no problem. What's up with that?

Android :: Illegal Argument Exception When Trying Run Open GL ES 2.0 Application

Jun 12, 2010

When I add the following line to my GLSurfaceView class I get an IllegalArgumentException from some random place. I don't know where the problem is because it doesn't give a stack trace. set EGLContext Client Version(2); What else do I need to do to get an OpenGL ES 2.0 application to work? I have tested this with a completely empty renderer class (and also put breakpoints on every callback, and none of them get hit, indicating that the error occurs before my renderer even gets involved). Does anyone have a complete working example of how to get started with Android OpenGL ES 2.0 development? [There is also a stackoverflow entry here -> http://stackoverflow.com/questions/3026368/illegalargumentexception-w]

I can browse to address and see the xml results using the Android Emulator browser and from my machine. I have given my app the INTERNET permission.

I've seen it mentioned that I might need to configure a proxy but since the web service i'm calling is on port 80 this shouldn't matter should it? I can call the method with the browser.

Android : Received App.Application Null Pointer Exception

Sep 23, 2010

When my app loads, I fill my android.app.Application with some data. The app runs fine as I use it and all the data is available. However, when I leave the app over night and look at it again the next day, I receive NullPointerExceptions when attempting to use that same data. I do not believe Application objects get garbage collected, so I have no idea what is going on? I also lose static objects in classes used by my Activity classes. I am on Froyo 2.2 on a Google Nexus One. Looks like someone else had a similiar issue: http://groups.google.com/group/android-developers/browse_thread/threa...
