I am writing an android application in which users can pick a photo from their gallery and upload it to a server. How should I accomplish this? The application mainly uses SOAP webservices to communicate with the server, but I do not know how to serialize a stream of bytes in KSOAP and therefore I need some help. The solution should not necessarily use KSOAP. A valid solution would be to upload the photo on some server, and just retrieve the URL, which will be stored in the database.

Has there been an upgrade to the market that changes the minimum requirements for an app? I have taken a couple months off and now whenever I try to upload an app, I get the unhelpful message "The server could not process your apk. Try again.". This happens even when I upload the exact same apks that I have uploaded before and ones that work fine with adb push onto devices.

Since this morning, I've been getting the error in the subject when I try to upload a new APK version to my Market Developer Console. At first, I figured it was just a brief server outage, but not since it's gone on all day. I also suspect it's only affecting me, since I've seen no other mention of it on this group. Well, I'm mentioning it now.
Anyone come across this before? I've released enough APKs that I'm quite familiar with the Console; while that doesn't rule out a stupid mistake, of course, I don't think that's the case here. Obvious possibilities that I think I HAVE ruled out: I've confirmed that it's the correct package name, and that it's signed with the same key as it always has been. Beyond that, I'm not sure what to consider.
I have also contacted Market Support, with no response as yet. And I did notice that this morning was the first time the "Draft application" feature became available on my Console; not sure if that's relevant, but coincidences are suspicious.

I have 3 days into this and my mind is melting oozing out my ears...
The end result is that I want to upload selected photos from and Android phone to a php website.
I can display the images from the camera and get the filename that I want to upload. However I cannot use FileInputStream on the file name because it is not private to my application. Use FileInputStream generates an error that the file contains a path separater.
Does anyone know how to get the filestream running? Do I have to copy the file into a private file store?
After 3 days of googling this I am amazed I haven't that answer.

I need to upload an image to a remote PHP server which expects the following parameters in HTTPPOST:
*$_POST['title']*
*$_POST['caption']*
*$_FILES['fileatt']*
Most of the Internet searches suggested either :
Download the following classes and trying MultiPartEntity to send the request:
apache-mime4j-0.5.jar
httpclient-4.0-beta2.jar
httpcore-4.0-beta3.jar
httpmime-4.0-beta2.jar
OR
Use URLconnection and handle multipart data myself.
Btw, I am keen on using HttpClient class rather than java.net(or is it android.net) classes. Eventually, I downloaded the Multipart classes from the Android source code and used them in my project instead.
Though this can be done by any of the above mentioned methods, I'd like to make sure if these are the only ways to achieve the said objective. I skimmed through the documentation and found a FileEntity class but I could not get it to work.
What is the correct way to get this done in an Android application?

when using it with an imap (not gmail) mail account, can k-9 upload the emails you send from the mobile to the 'sent' folder on the imap server? I searched several forums reviews blogs etc but couldn't find anything on this point. It would be very useful because it would allow me to easily keep track of the emails I send from the mobile, just like I do with Profimail on my Nokia at the moment.

I'm writing an app that uploads files to a web service. My question is how to write a Service to handle this: I want to upload in a background thread (or process not sure of the precise wording), so that the user can go to other applications without interrupting the upload, and show a notification / kill the thread when the upload is complete.I'm guessing it should be a Service, with a Notification to show the user what's going on: but should it be a LocalService or a RemoteService, as per the API examples? And do I need to call a new thread once I start the service, or do all services by definition run in a different thread?

I have run into an requirement of my application that i cant find a way to do this.
I need my application to be fullscreen and no title bar (done), and this application will have a background image. However, all the activities/views of my application must be transparent/translucent so the application background will be visible all the time behind the information i am displaying.
Basically i would like to have this behavior
http://www.geeky-gadgets.com/wp-content/uploads/2010/05/amazon-kindle-android-app.jpg
supousing that the image you see is not the phone wallpaper, but the application background image. What would be the application configuration in the manifest file and what would be the configuration for eacy activity/view?
I also noticed that, i need to setup each activity to be fullscreen without title bar. Is there a way to do this globaly in the application so all activities will behave this way?

I have a service that listens to the serial port. According to data received from serial i switch between particular service states, and start particular activities on state transitions. I would like to accomplish it in following way: Let's assume there is one active Activity1 started from previous state, I call startActivity from service to start a new one Activity2, but I want to simulatenously destroy Activity1 when Activity2 gets on top of the stack. I tried to call finish() in Activity1.onStop but it seems not to work (Activity1.onDestroy() doesn't get called). I'd prefer to finish Activity1 after Activity2 gets on top in order to avoid blinking.

I have a service that's running in the background, is there any way (short of keeping a count of onBind() and onUnbind()) to know the number of activities that are bound to it?
I am trying to provide a "quit" function. all my activities derive from the same base class. I am keeping a global static around that says the "quit" button was pressed. then on each of the activities onResume() method, I look for the global static "quit" variable and if it's set to true, I call "finish()" so my activity shuts down, and then next activity on the task stack appears -- which goes through the same process of checking the global static "quit" variable until it gets to the root activity -- which effectively goes back to the main desktop screen.
However, I need a way to reset the global static "quit" variable, otherwise, when I launch the app again, it will check the global static quit variable and shutdown immediately - never coming back up. So, I want to know if there are any activities bound to my service, if not, I would set the global static "quit" variable back to false so that the app could be relaunched again.

I have an Android Service that I would like to keep running even after the last Activity has been popped off the stack, or the User has chosen to do something else.
Essentially the Service is listening for changes on a remote server, and I would like to generate a Notification if and only if an Activity from the app isn't running(or visible). In other words, I don't want the Notifications to occur while the User is directly interacting with the app.
In the case where the User is directly interacting with the app, the Service will notify the Activity and update appropriate UI elements based on the changes. I plan to implement this through the Observer pattern.
How can the Service know if none of apps Activities are bound to it?

I am using a TabActivity (Main) with 3 TabSpecs
I am using Intents for the content of the 3 Tabs
TabA, TabB, TabC for example.
All these tab activities use common data that is stored in SharedPreferences
In the Main TabActivity I have an options menu which has a refresh option.
CODE:.............
This refresh uses an AsyncTask (updateCommonDataFromWeb) to reload the common data from the web.
I need a way to tell the 3 tab activities to refresh their views and rebuild their content from the newly downloaded data.
When the tab activities are first created they load the data from SharedPreferences like so:
CODE:..............
I thought about making a common method on each of the tab activities
like.... reloadViewData()
I thought maybe I could use the activity manager from the Main TabActivity to get the activity of the current tab like so:
CODE:.............
Unfortunately i cant get this approach to work, whilst activity is the correct instance its an Activity instead of a TabA,TabB or TabC
Maybe i've completely taken the wrong approach to the whole thing.
I have also read alot about not using Activities for tab content instead using views.
However I dont know what view to use to replace my <RelativeLayout /> as i cant use my R.layout.* as views.

I am programming a game. I have a service for the background-music. When I press the home-button and leave my activities, the service still runs in background. How can I stop the service, when there is no more visible activity in my program and restart it, when the user goes back to my game (some activity of it)?

Is there a way I can test if there are any other activities in my app still alive? I am looking to stop a service in an onDestroy method, but only want to do this if there are no other activities from my app still alive on the stack.
I have the call stop the service in the main activity's onDestroy() method. This works perfect EXCEPT that if a user launches my app, then launches a few activities in my app, then hits the home screen and RELAUNCHES my app, they will subvert my order and the main activity will now be above other activities of my app. From this state, if they hit the back button and 'back out' of my home screen they will trigger the onDestroy() method and kill the service even though there are other activities open on the stack. I want to avoid this by stopping the service ONLY if I am sure there are no other activities of mine open on the stack.

I currently have a service called ConnectionService. It instantiates a Connection object that gives me access to a controller of TCP.
I start the service from a splash screen activity, which sends and intent and starts my "main" activity once a connection has been established. In the "main" activity, I can access my Connection object and communicate with the controller. However, when I start a new activity from the "main" activity and bind to the service, I get a NullPointerException when I try to call methods in the ConnectionService.

I want to create an application to remote control my PC.
For example: Volume (get actual volume level, increase/decrease/mute volume), TVtime (start/quit tvtime, get actual channel, toggle fulscreen, channel up/down, toggle input source, toggle aspect ratio), Amarok (start/quit amarok, get current song, prev/next song, play/stop/ pause), etc.
The application for the PC is done (in python). The communication protocol used is very simple.
For example: "volume:get_level", "volume:up", "volume:mute", etc. Now I'm working on the android application.
What I have implemented till now is to create an activity, with: - an edittext to enter host:port - a button to connect/disconnect to/from server - the onCreate method creates a new thread for socket communication to send/receive messages to/from PC. - a textview to display information received from PC (eg. volume level) - a button to send command to PC I'm using handler to communicate between the tcpclient thread and the main activity.
It is working... But I want to use more than 1 activity. I want to use different activity for every program controlled. Searching for a solution to transfer the thread's handler to a new activity I have found that it is not possible, and I have to use a service.
So, my question is: how to send message from different activities to the same service, how to send message from service to the actual activity and how can I check in the service which is the actual activity? Because the service is running in the same thread as the activities I suppose that I still have to create a new thread for socket communication. How can I send the data received by the socket to the service?

I have a service component (common task for all my apps), which can be invoked by any of the apps. I am trying to access the service object from the all activities, I noticed that the one which created the service [startService(intent)] has the right informaion. But rest does not get the informaion needed.
My Code is as below:
CODE:................
If I invoke startService(intent). it creates a new service and runs in parallel to the other service.
If I don't invoke startService(intent), serviceObj.getData() retuns null value.

I'm trying to refactor/redesign an Android app. Currently, I've one UI activity (Activity 1) that creates a DataThread. This thread is responsible for network I/O and interacts (provides data) with the UI activity via a handler.
Now, I want to add another activity (a new UI screen with Video) - Activity 2. Activity 1 is still the main activity. Activity 2 will be invoked when the user clicks a button on Activity 1. Activity 2's data also comes from the DataThread.
My idea is to put the logic of my DataThread inside an Android Service (DataService). My question is - can more than on activity bind to my DataService at the same time? Is there a way to tell the service to provide data to a specific activity only?

The official documentation describes tasks as follows: All the activities in a task move together as a unit. The entire task (the entire activity stack) can be brought to the foreground or sent to the background. Suppose, for instance, that the current task has four activities in its stack three under the current activity. The user presses the HOME key, goes to the application launcher, and selects a new application (actually, a new task). The current task goes into the background and the root activity for the new task is displayed. Then, after a short period, the user goes back to the home screen and again selects the previous application (the previous task). That task, with all four activities in the stack, comes forward. Is there a way to programmatically detect when the task of the current Activity moves into and out of the background? I would like to know when the user has switched switched to another application, vs. when the user navigated to another Activity in the current app.

I am designing an app that will have some activities separated in tabs. Some of them will have to perform tasks in the background will the user is in another tab. What is the best strategy for designing an app like this? I was thinking about using a service but it can be killed by android dalvik, isnt it?
