I'm using URLConnection to connect to the main server. The server implements digest authentication. If I connect to the server with java library, the connection is successful. But if I use the same code for android, the connection is rejected for the reason - username and password do not match.
Here is the code for my Java project:
code:...........
The above code works fine and I'm able to connect to my host server which is implementing digest authentication. I'm unable to use the same code for Android to connect.
Here is my android code:
code:.........
If the same code works for Java, it should also work for Android.
The code loops in the Authenticator as it finds username and password not matching in the Android code for some reason which in fact are correct. The code runs perfect for Java project.

I have a Service Receiver and a phone state listener class to determine the status of the phone. When the state is "CALL_STATE_RINGING", I call upon the method stopAllPlayback() in my main Activity. It is at this point that users report "Forced Close" messages. Can you help me determine where the problem might be? I'm new to Java so I'm not 100% sure how to troubleshoot based on a stack trace.
Here's the stack trace:...............

I have developed an application which has tabActivity using SDK 1.0 r2.
1st Tab contains List view. -> the list contains some images
2nd and 3rd contains some webviews.
The app works fine on G1 mobile.
Today I downloaded SDK 1.5 and ran the same app on SDK 1.5.
The app got crashed when I scroll down/up the list items very fast (fling)
code:............
I am not understanding the above error log.
Then I experimented some thing like this: I removed the TabActivity, just shown only list activity. Then I scroll down/up the list items. Then there is no crash.

In my application users take photos with an Activity that implements SurfaceHolder.Callback. The uri.toString() is then passed as an extra to a subsequent Activity that displays the image. All fine, except for in Android 1.6 the jpgs on the sdcard have a strange noise when looking at them through mac finder or win explorer after mounting the sdcard. The images have purple and yellow stripes on their upper half. Fine on camera gallery.
Here's some relevant code.

Im writing a program that offers a quick reply dialog upon receipt of an SMS.
However, I am getting an unexpected result. When I receieve an SMS, the appropriate dialog activity comes up displaying the correct phone number and message, however there is a second activity behind it that is the 'default' activity in my program (it is what opens when i launch my application)
I do not want this second activity to come up. The quick reply activity should come up by itself over top of whatever the user was doing before.
The 'floating' activity:

I'm writing an application that starts with a loading activity. In the loading activity the app requests html from web and parses the html, then it sends the parsing result to the main activity. The main activity has several tabs, and contents of these tabs are based on the result of parsing.For example, the result of parsing is a list of strings ["apple", "banana", "orange"], and I need to pass this list to main activity, so that the main activity can create three tabs named after three fruits.I would like to know if there is any way to pass a list of strings among activities, BTW, is it the common way of do this?

I created an application which enables the user to set whether he wants to receive notification while the application runs in background mode. If the notifications are enabled an activity should be started (the dialog should appear on the screen).
I tried to enabled it the following way:
CODE:...........
This is the method from main activity. When onPause() is executed isRunningInBackground is set true.
When I tried to debug it when the main application was running in the background the line
startActivity(intent) had no effect (the activity didn't appear).
Does anyone know how to midify the logic in order to start an activity from the main activity when the main activity is running in the background (after onPause() is called)?

Need an example of how to create/start a new activity from the main activity. I have a button click event on the main layout. Originally I just used setContentView(R.layout.secondactivity); which brings up the layout but I don't think that is correct since the secondactivity class is not instantiated at this point yet. I have looked for such an example and can not find one.

I hav an app that is like a relational database. There is a main app activity that users manage things with. There is also a widget that will display important info and add data to the database. When the widget is clicked, a configure class displays a way for the user to edit data. When the configure activity is done, the widget is updated and instead of going back to the home screen, the apps main activity is started. I can't find where the main activity is being called from. Wouldn't I have to create an intent and start Activity() to get this behavior? When done updating, I want the home screen and not my app.

I just got back from my local VZW store. No line. I immediately downloaded Google Maps. It installed and ran fine.
Turned on Google Navigation and navigated home. GPS locked quickly, seemed accurate (within reason, maybe 25-50 feet) and gave perfect spoken turn-by turn directions. Woo hoo.
I am gonna download some things and play for a while, but my # 1 concern looks to be appeased right now.

I keep getting error: device not found when I try to use adb with my phone.
~Windows XP SP2, 32bit
~The SDK is installed and working.
~The USB drivers have been downloaded through the SDK.
~The phone is in USB Debug mode.
~The USB drivers have been installed in windows.
~Windows device manager shows that everything is working fine.
~Windows recognizes the phone when it is plugged in.
The ONLY thing that does not work is that the phone won't show up in the list of devices adb sees. Everything else appears to be setup and working just fine!

Has anyone else downloaded this off of the market yet? It's the smoothest home replacement I've tried yet, and even has the pinch helicopter view. Only downside thus far is that you can't customize the four shortcut icons at the bottom, but they're my four most used programs anyways, so I don't really mind. And that you can't use HTC widgets, but I expected that.

long story short I dropped my hero into a glass of water while half asleep. I immediately pulled the battery out and threw the whole thing into a bag of rice for 2 days. Pulled it out today and it works. But theres noticeable water streaks on the screen when you look at it from an angle. Will these streaks ever go away? I have insurance, so I can get a new one for 100$ but not sure If I should throw the money at it since it still works perfect, minus these ugly streaks.

From digging around a bit, getAssets() is an inherited method from ContextWrapper. It returns an AssetManager, and using open() it can return an InputStream. What I'm attempting to do at this point, is use the GLSurfuceViewActivity, Cube and CubeRenderer to work and learn off of and read in vertex data from a binary file. I've already created the binary output by parsing a model obj file and added to the assets directory. My Shape class (modified from the Cube class) does not have access to calling getAssets() since it's not a subclass of Activity or ContextWrapper. Once I accepted that, I tried to think of the best way to read in the data (without storing it extra places) to the Shape class. What I did, and seems to be working okay, was modify the Shape and ShapeRenderer constructors to accept an AssetManger as a parameter.

Is there a way to manage application activities by hand, like this: user activating an application from menu, it does some initialization, then creates some activity (is it necessar y to declare all activities in the application manifest?), and listens to it's events. On some event application decides to close one activity and open another - so it contains all the application logic. Didn't found anything like this in examples, they all have all the logic in the activity classes. Maybe I need to user Services? (Maybe I don't understand right, what an activity represents. For me it's like window in windows, or Displayable in j2me) I'm very new to android development, trying to understand the basics.

I have a service which collect data and send them to a certain URL and updating the main activity GUI, so which is better in the performance to use a long service with listeners to collect the data and threads in it to update the GUI and sends to the internet or to make another service responsible for updating the GUI and sending to the URL only while the first one just collects the data?

so the application I've written has a service (that tracks GPS data) with a single main activity that binds to it with bindService in it's onStart() method, and unbinds from the service in it's onStop() method using unbindService( ServiceConnection ). I also have an activity which is an options screen, that is launched by pressing a button on the main activity. On this options screen, I have a checkbox that says "Run in background", which, if set to true, means that when the user exits the application with eier the Home or Back buttons, the service will continue running, not turning the GPS off. I do this by calling this.startForeground onUnbind, and this.stopForeground onRebind, if the setting is set to true, and stopping and starting my location reader onUnbind and onRebind respectively if the setting is false. If the service is running in the background, it also displays a notification to ensure the user understands that the GPS is still running and draining their power. This notification is displayed and stopped by relying on the startForeground and stopForeground methods......
