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.
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):

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

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:

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)
I have developed simple application of progress bar in that when I hit the button then it will do some work in background and one progress bar is visible on foreground. afte completing back ground work it display the same screen. It works fine if I don't rotate mobile but when I rotate mobile then it throws java.lang.IllegalArgumentException: View not attached to window manager
I know when we rotate the device or open keypad it starts activity restarted. But How to avoid this error. My code is.

I have two projects in Eclipse: service and UI client.
In onCreate in UI client I have:startService(new Intent(this, ExampleService.class));
But this fragment: ExampleService.class throws NoClassDefFoundError exception at runtime. I have installed ExampleService.apk, and ExampleUiClient.apk. Project compiles, and everything looks fine. What I am doing wrong?
Is it possible to start service from other apk?
I am having this problem with the android database. I adopted the DBAdapter file the NotepadAdv3 example from the google android page.
CODE:...........
The error that i am receiving is from Log.e(TAG, e.toString()) in the methods retrieveKey() and storeKey() "no such table: myuserkey: , while compiling: SELECT userkey FROM myuserkey"
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?
I have a Thread that downloads data from internet

There is an activity that needs to be updated according to downloaded data.

Whenever I run above code I get NullPointer Exception .Please help me to update the view.
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.

I created a sql lite database with the following columns:
static final String dbName="demoDB";
static final String tableName="Employees";
static final String colID="EmployeeID";
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
db.execSQL("CREATE TABLE "+tableName+" ("+colID+" INTEGER PRIMARY KEY AUTOINCREMENT, "+
colName+" TEXT, "+colAge+" Integer);");
I want to select all the records in the database like this and display them in a gridview:SQLiteDatabase db=this.getWritableDatabase();Cursor cur= db.rawQuery("Select "+colName+", "+colAge+" from "+tableName, new String [] {});String [] from=new String []{DatabaseHelper.colName,DatabaseHelper.colAge};
int [] to=new int [] {R.id.colName,R.id.colAge};
SimpleCursorAdapter sca=new SimpleCursorAdapter(this,R.layout.gridrow,c,from,to);
GridView grid=(GridView)findViewById(R.id.grid);
grid.setAdapter(sca);but i receive the following exception:java.lang.IllegalArgumentException: column '_id' does not exist.the db table does not have a column with name '_id'so what is wrong with this code
In the following code, these lines:
CODE:.........
The app keep throws the Rescources.NotFoundException. I checked the xml file, all the ids are defined and they are all in the R.java. So I really don't know why the app throw this exception.

I would like to do some tests on SlidingDrawer however i always found RuntimeException when SlidingDrawer.onMeasure is called i check the code and think the exception is caused by unspecified MeasureSpec
so i would like to ask how to setup the MeasureSpec in SlidingDrawer?
I have recently noticed that when Running the function geoCoder.getFromLocationName() on android 2.2 (Froyo) then i Receive a IOExeption (Which does not occur on other SDK versions).
After some reserch i have found suggentions to add the following Permisions:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
However this does not solve the problem, and this appears to be a Android SDK Bug.
Is there a knows solution to this problem?
Here is the stack trace though it is not particularly helpful the inner stack trace is null so not great.

My XML layout in res/layout/edit.xml: Code...
When I try to switch from "edit.xml" to "Layout", I see this error: java.lang.UnsupportedOperationException: addView(View, LayoutParams) is notsupported in AdapterView I checked the documentation for AdapterView, and this is expected behavior. Why, then, does ADT expect it to work?
Is there someone troubled the same issue.

I have an android application that I am supporting and after calling one of the activities numerous time, it throws a stackoverflowerror when trying to get the extras from the intent.

I am using HttpURLConnection to send a GET request to a server. Upon reading the response code, the Android implementation of HttpURLConnection.doRequestInternal() throws an exception:
"java.io.IOException: Received authentication challenge is null"
I don't even get what the error is trying to tell me. I write an OAuth param string to the Authorization header, but this works fine on other occasions. There is nothing peculiar about my request apart from that.
Any idea what this means, what is causing this and how to get around it? This works fine with Sun's Java implementation, so I guess it's a problem with Apache Harmony?
My calls to getFromLocationName() always fail the "first" time I start my app. I catch the IOException which has reason:
Unable to parse response from server
Then I make a second call and it succeeds. Once things are "awake" all future calls to getFromLocationName() succeed, it's just that first one, and there is a ton of latency.
I haven't run this on a device yet, just in the emulator. This seems like a network problem, but it is so reproducible I'm thinking I'm not initializing something properly. I'm using Android SDK 1.1.
i want to implement a client for https, all in my localhost (in my apache, it is configured to ask authentication), with a resource " https://localhost:443/resources/resource1.xml" the server works fine.
I have a client for desktop, and it works fine, the resources are consumed using httpcomponents-client-4.0.3), i have readed that Android uses that version.
This is the code of my client in Android (practically is the same of desktop mapped to android) ,

I found this example where they used PowerMock and EasyMock to stub/mock the Menu and MenuItem classes for android. I have been trying to do something similar with PowerMock and Mockito with the Activity class.
I understand that a lot of the methods are final and that in the Android.jar they all just throw RuntimeException("Stub!").
I also understand that this test isn't complete but I just wanting to see if it is possible to mock the android Activity class.
But given that PowerMock allows you to mock classes with final methods shouldn't this code work?
CODE:............
I would think that the RuntimeException would no longer occur and "Title" would be returned but it still throws the exception.
I have tried all sorts of different things like doReturn("Title").when(mockActivity).getTitle(); and suppress(constructor(Activity.class));
I have a problem with a strange out of memory exception that only occurs on some devices (mostly HTC Desire). It happens there every time a user starts a certain activity (no matter how - there are two paths to that activity) and i'm really puzzled as to why (i checked for leaks and couldn't find any)...
The error is either thrown when calling setContentView or shortly after.
This is the code block that throws the error:
CODE:.........
As i said - the error is usually thrown when calling setContentView or when calling getMonthTimeStamps()
getMonthTimeStamps is a helper function which creates a list of dates available in the internal database. It creates a couple of (small objects) and returns an ArrayList.
Here is the function:

I'm not claiming that my code is flawless or perfect, but i really don't understand why this error is thrown. The XML-layout doesn't contain any references to images and not very complicated (textview, spinner, tablelayout).

I think the error is from this manifest file? when i want to start this activity "SearchResultForm" i have the exception?

It works fine on the device, but the Emulator throws an Exception:

I'm not sure if this is just an emulator thing, or whether this could replicate on a real device?
I read somewhere not to exception handle when developing in Android, is that true?
If one does need to exception handle are there any logging tools for 2.1 and above?
If shouldn't exception handle, why is it not recommended to at least use the below?
try {body-code} catch (exception-classname variable-name) {handler-code}
I am working on the task to search a location which stored in DB. After that i have to drop a pin on the corresponding location. I made a modification on Quick Search Box(QSB) to search the DB which is in my app. for that QSB performance i followed the Search Dictionary example in API Demos. when i click the search suggestion it reloads the current activity and drop the pin on it. when click the back button it shows the below exception in the Logcat. why it happens.
