I'm trying to make an AppWidget, and for some reason the Eclipse debugger doesn't suspend on any of the breakpoints I set (but I know the code is executed because I see it working on the emulator). I don't have this problem with other 'regular' apps (non AppWidgets). Is this a known limitation, or is it just a problem on my installation?

Im working on a widget, I'm using eclipse and windows vista 64 bit. I run the app in debug mode and I put a breakpoint on the context.startService line below but the app isn't stopping. My widget is displaying as expected, just showing my frame and some text saying loading.
CODE:..............
When I am running the emulator my console gets spammed with messages like this, even when im not in debug mode. [2009-05-20 03:02:38 - ddms]Can't bind to local 8643 for debugger
We have discovered a potential bug in the implementation of AppWidgets. Here is a simple reproducer.
Attached is the code for an application containing a TestActivity and a TestWidget. TestActivity extends MapActivity and TestWidget is a simple widget provider which updates a TextView every 2 seconds. Now if the TestActivity is launched with no instance of TestWidget running, it works just fine. But if the TestActivity is launched after placing the TestWidget on the home, it results in ClassNotFoundException. Here is what we get:
CODE:.............
So it seems we have an inconsistency in the way the class loader works for the same apk.
WORKS - Launch the application by itself, without invoking the Widget. DOES NOT WORK - Create a Widget on the Home screen and then launch the application from the launcher.
The source code for this application (http://www.yousendit.com/ download/TzY3ZGVhZy96NE4zZUE9PQ) has been attached. Hope someone from the Android team can shed light on this behavior.
This error is seen on the 1.5r3 SDK. Not sure if this has been addressed in 1.6 and 2.0 SDKs..
We have created an AppWidget that takes user inputted text into an EditText and displays a calculated amount of text inside a TextView on the Home Screen. We calculate the amount of text based on the AppWidgetInfo.minWidth, minHeight attributes. We do this to simulate scrolling; we cut up the user-inputted text into chunks that will fit into the widget and swap them based on button clicks.
When we save the widget with the device in Landscape mode, it calculates the appropriate amount of text for Landscape mode and displays it in the widget. The problem is when the user changes orientation of the device to Portrait mode (without opening the widget and resaving the text), the calculated amount of text for Landscape mode is still displayed. This also happens in the vice versa case (the user is in Portrait and saves, etc.)
How can we tell our AppWidget to recalculate the amount of text displayed on screen orientation change? Is this possible? How would you solve this problem?
I'm making an Android AppWidget to sit on the home screen.
The user's home screen space is precious, so I want the widget to be small. The ideal size would be 2x1 cells.
Some documentation suggests you can have any size you like?
But the AppWidget graphical design guidelines imply that only standard sizes are supported: 4x1, 3x3, 2x2.
Does that refer to the available PhotoShop templates or is it a limitation of Android itself?
I'm finding that a 2x1 widget works on my actual device (HTC Wildfire) but expands to 2x2 on the emulator.
HTC have their own special implementation of the home screen, so maybe my widget will only work at 2x1 on HTC devices?
Is there any way to create a 2x1 widget, or should I use a standard size?
My widget was adapted from the Simple Wiktionary sample.
The manifest has android:minWidth="146dip" and android:minHeight="72dip".
There's a RelativeLayout with android:layout_width="fill_parent" and android:layout_height="wrap_content"
I'm just starting with Android, so apologies in advance if this is a silly question. :)
There is a given set of predefinied Views that can be used in layouts for AppWidgets. How can a customized View added to this list?
The minimum requirement is that the class is annotated with RemoteView. What else is necessary to be acceptable as view in the layout.xml?
Is it possible to programmatically create and/or destroy AppWidgets?
View 7 Replies View RelatedI'm writing a widget. Currently, I'm have a simple ImageView, and calling RemoteViews.setImageViewBitmap(). I'm using a service to do the updates.
I thought it might be a good idea to reuse an existing RemoteViews instance, so I'm only querying it the first time around, and subsequently simply call setImageViewBitmap() with the new image.
This works well initially, but after some time I first start getting "!!! FAILED BINDER TRANSACTION !!!" errors, and later, an OutOfMemory exception.
Simply creating a new RemoveViews instance every time works flawlessy on the other hand. I'm just curios why that would be, any ideas?

View 1 Replies View RelatedI am trying to debug my application on Emulator, but it just stucks off on one message "Waiting for Debugger - Application XXX is waiting for the debugger to Attach". Its really annoying probably I am missing something.
Im programmign on Windows with Elcipse and a Motorola Droid. ADB will successfully download the code to the Droid and run it, but ive been unable to get debugging to work either remotely or with the emulator. (To be honest Im having multiple problems with the emulator and id rather just not have to use it.)
Does remote debugging work? If so, how would I get it working? If not, does emulator debugging work and how would I get that working?
Right now my "debugging" consists of setting the text of an onscreen text-view, but thats not a good long-term solution.
Whenever I try to run debugger for my applications, it gets stuck on "Waiting for Debugger." It works fine on a ADP1 phone. Leaving it for a while ends up restarting the phone. I even reset the phone to factory mode and the problem persists.
View 2 Replies View RelatedI was debugging away and moved my phone a bit and the debugger lost contact. I figured it was just a loose USB so I reseated the cable and attempted to restart the debugger. Now the debugger can't find my phone. I can manage the phone from DDMS without any problem so it's not a phone, cable, or driver issue. Something went wacko in the debugger setup. When I go to Run Configurations in Eclipse, the phone is simply not in the list of choices. Any ideas where I can look for what's wrong?

View 1 Replies View RelatedIt seems like every step I take in the Android world I run into problems. Im soon up to 20 questions here on StackOverflow hehe =)
Usually, I have my HTC Hero connected to the computer via USB and I launch the application either in debug mode or in normal mode.
So, the last time I ran the app in normal mode. Then I disconnect the device (I want to try to have it "free", not connected to computer) and I start the app from the menu. When I do that I get a popup saying "Application xxx is waiting for the debugger to attach" and there it stops and eventually dies.
Why is it waiting for the debugger, when the last time I ran the app (while connected) I didnt run it as Debug?
Im asking because Im trying to debug a SQL query problem and adb only seems to show part of the SQL string and chops off the end.
Im getting an "unrecognized token" error when running a query:

As you can see the query above appears truncated.
I am debugging an app that tests an API I wrote. There is a section of code that simply reads a DB cursor like this:

It seems that DDMS does not accept that a debugger in another host connects to it (a scenario where host A has the Emulator and DDMS running, and host B has the debugger). It appears that DDMS is binding to the loopback address. Does anyone know if that is intentional ?
View 2 Replies View RelatedDoes anyone know how to get the debugger to launch on an ADP1?. It was recently flashed to 1.5. Dev platform is Eclipse on Windows XP with the SDK 1.5 USB driver installed (HTC Dream Composite Interface). Windows can see the device and adb can see the device with "adb devices" command. USB Debugging has been enabled on the device and the application manifest has android:debuggable="true" set in it. The LogCat windows is showing log output from the ADP1 too.
But when Selecting Run->Debug or Run->Run the avd is always launched. The instructions say that it should launch to the device or give a choice if the avd is running too.
Do anyone know what needs to be done to get the debugger to launch against the real device instead of the avd?
Assuming I didn't start in debug mode, is there a way to make the eclipse debugger automatically start if my app throws an exception inside the emulator?
Alternatively, is there a way to get a more useful error message out of the emulator (something more useful than "Sorry, your app terminated unexpectedly").
Is possible to uninstall factory apps with root access.But, ADB have 'root' command that give root access to the terminal what you are in, so, in this case, factory apps can be uninstalled by androig debugger with root acces?
like:
adb root
adb uninstall XXX
I've literally spent 15+ hours trying to figure out this one bug (when I should be studying for finals). Any help is greatly appreciated. The bug appears on the dev1 phone running cupcake. It was not present before the upgrade. Basically, the problem is that when a activity with a webview and 2 threads is run, the service that runs after it will always crashes the process (but it works fine when the debugger is attached). The worst part is that it crashes at arbitrarily places in the service, so I can't isolate the error.
The details:
I have an activity with a WebView. The activity executes two threads, one after the other using the basic new Thread(new Runnable() {public void run()... Both threads use the same handler to report back results to the main activity. Flow works like this: when the activity starts, the first thread gets data to construct the URL that the webview will load (using DefaultHTTPClient). Then when the user navigates to a certain page, the second thread is again fired (using DefaultHTTPClient) to get some xml. This works fine.
The problem happens right afterwards. Once the activity with the webview finishes (it calls finish on itself), a service is started that has a thread that using DefaultHttpClient to downloaded some xml, process it, etc. The service crashes at arbitrary points with no error messages, simply displaying a memory dump, and kills the main process with it. When I attempt to debug the process, it runs just fine w/ no crashes. I've repeated this at least 30 times, with the same result. (no crash w/ debugger, crash when installing signed apk file to device and running it).
The program doesn't crash when the threads are removed from the activity with webview. So even if the webview activity runs (but all threads are removed), the service runs just fine regardless of the debugger.
Here is how my threads start (both of the ones in the activity with the webview, and the main thread in the service that is launched afterwards):

Here is what logcat displays:
