• What is the purpose of both target API and minSDK

  - by Scott Ferguson

  Can somebody explain to me the difference between the project target and the minimum SDK? I want my app to run on Donut devices, and the APK I built with a target of 7 worked just fine. When I set an explicit minimum SDK in the Android manifest of 4 (1.6) the compiler bitched at me that the target exceeded the minimum. I reset the target to 4 only to see what would happen, and now I've got compiler errors. An example is the START_NOT_STICKY constant in android.app.Service. It doesn't exist in API level 4, but does exist in API level 7. This is also the case with Service.onStartCommand(). In API level 7 you need to explicity override this method, whereas in API level 4 you don't. So why does the app work in 1.6 despite all this? How could 1.6 know how to use SERVICE_NOT_STICKY when the associated API level doesn't know about it?

• iPhone GameKit Picker Fundamental Connection Issues

  - by Kyle

  Hello.. This is one of the more interesting things I've seen in iPhone development. The following question has nothing to do with code because I'm using an SDK Example from Apple (Tanks example). I have a 3GS iPhone, and a 3G iPhone both showing the GameKit picker screen. Both will eventually show the other phone in range just fine (It does take about 25 seconds, though). If I pick the 3G iPhone with my 3GS, the 3G will get a connection request and a connection can be made. However, it will ABSOLUTELY not work in the vice versa. Both phones have bluetooth switched on, and both phones are running the latest OS version. The simple fact is I'm using the SDK example, and it's just not working for the 3G trying to issue the connection. Is there any way to explain this extremely odd behavior? Thanks alot for reading!

• How to create a Word document from a Silverlight 4 application

  - by George Durzi

  I'm looking for some options to programmatically create a Word document from within a Silverlight 4 application. I found two approaches which seemed promising at first but don't look like they will work. OpenXML SDK The OpenXML SDK isn't available for Silverlight at this time. Word Automation via COM Interop dynamic wordApplication = AutomationFactory.CreateObject("Word.Application"); Apparently this requires that the Silverlight 4 application be granted permission to run with elevated privileges, which is only available for out-of-browser applications (which ours isn't) My other thought is to hand off the request to a back-end service which doesn't have these limitations. Wanted to check for any ideas before going down that path. Thank you!

• IPhone App Signing: A valid signing identity matching this profile could not be found in your keycha

  - by Ben Reeves

  I'm pulling my hair out over this. I just downloaded the iphone 3.0 SDK, but now I can't get my provisioning profiles to work. Here is what I have tried: Delete all provisioning profiles Delete login keychain Create new "login" keychain, make it default Create a new cert signing request Create new developer and distribution certs in the apple developer center Download and install them Download the WWDR cert and install it Create a new provisioning profile and double click it to install All the certificates report as valid, but xcode still won't recognize them. Anyone got any ideas? Thanks Edit: I completely re-installed osx and from a fresh install installed the 3.0 sdk and still the same problem.

• Android 2.2 AVD: no Quick Search Box?

  - by Felix

  I have recently updated my Android SDK to include support for Android 2.2 (API level 8). The app that I'm building integrates with the Quick Search Box (QSB) home screen widget, which I can't seem to find in this version (using both vanilla 2.2 and the Google APIs version). I was kind of excited when they announced that they have improved its functionality, but it seems there's no way for me to observe it. Is this normal? Are others experiencing the same issue? Or is this somehow related to my setup (running Archlinux and installed the Android SDK from the repositories).

• Project Active Executable can no longer be iPhone 3.2

  - by Rudiger

  I don't know how much you can help me because its under the NDA, but I recently updated to the OS 4 beta 3 xcode version. My project worked fine under 3.2 but under 4.0 parts are a not quite right I assume because it is still being developed. Every other installation of the beta sdk I could go into the project settings and select the iPhone 3.2 sdk and then change the target iPhone OS in the top left of Xcode but not this one. If I select 3.2 it still loads on 4.0 it seems I only have the 4.0 simulator. Under Active Target there is only 4.0. Any ideas how to get the 3.2 Simulator back?

• Why not standard Android emulators?

  - by Gerry

  I'm new to Android, but have published iphone and bberry apps. I see that I have to create an emulator using the SDK, before I can write and test an app. Why are there no default emulators? Why not at least a Nexus one, or HTC hero emulator shipped with the product? Sure its supposed to be flexible, but why not make it easy to create hello world and play around with a virtual Android phone? Both blackberry and iphone come with default simulators when you download the sdk. Thanks, Gerry

• getting all contacts (including from other syncAdapters) in android content handler.

  - by eyal

  Hi i have this Query: private Cursor getContacts(CharSequence constraint) { boolean hasConstrains = constraint != null && constraint.length() != 0; Uri uri = ContactsContract.Contacts.CONTENT_URI; String[] projection = new String[]{ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME }; String selection = hasConstrains ? projection[1] + " LIKE '"+constraint+"%'" : null; String[] selectionArgs = null; String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " ASC"; return managedQuery(uri, projection, selection, selectionArgs, sortOrder); } The first time issue it i give null as parameter to the function to the selection parameter is empty, meaning i don't filter any rows. The problem is i get only contacts i created myself using no syncAdapter. I used facebook app to synch my facebook contacts, but this query doesn't return them. I extracted the contacts2.db from the emulator and the view_contacts view shows me all the contacts, so the DB is updated. What should i do to get all the contacts regardless of how they were created (with which synch adapter)

• C# - Fingerprint Biometrics

  - by Jonathan.Peppers

  We are wanting to add support for fingerprint authentication in a .Net 3.5 application. We currently are only using the sdk from Griaule. But this only supports like 5 usb plug-and-play devices. We are wanting to support most readers included with laptops, tablets, etc. Is there a universal way to support many devices? I know there is a new standard starting with Windows 7, but we want to support XP and higher. Is there even a .Net SDK out there for UPEK or Authentec devices? Any ideas or help would be appreciated.

• How to recreate the default UIView the same as the default tableView:viewForHeaderInSection:?

  - by Hoang Pham

  I tried to implement the - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section to get the text label of the header in section of black color instead of the white color, but it looks so different from the default one created by the SDK, mine is so ugly. How to recreate the UIView with exactly the same as the one from the SDK? From Apple documentation: Discussion The table view uses a fixed font style for section header titles. If you want a different font style, return a custom view (for example, a UILabel object) in the delegate method tableView:viewForHeaderInSection: instead.

• Where is the Bonjour COM library?

  - by Twelve47

  I've downloaded and installed the Bonjour SDK for Windows on my Win7 64bit machine. I've tried to build both of the the projects in C:\Program Files\Bonjour SDK\Samples\CS. However they both reference Bonjour, causing me to get the following build error 'Cannot load type library for reference "Bonjour". Library not registered.' Bonjour appears to be installed properly as I can run the Bonjour Printer Wizard and it appears to work properly. Any idea why Visual Studio can't find the Library? I'm using Visual Studio 2008 by the way.

• Is there a Novatel Wireless Modem Emulator or something similar?

  - by David Brown

  Novatel Wireless provides their NovaCore SDK for developers wishing to interface with their line of modems. I'm currently developing an open source managed wrapper for it, but I'm having difficulties with testing. I own a Novatel MiFi and have mobile broadband service through Sprint, but that can only get me so far. The device is already activated, thus I can't test the network activation features of the NovaCore SDK. There are also certain features only available for HSPA modems, which I am not able to get in my area. Is there an emulator capable of emulating a Novatel Wireless modem so that I can test my library without physical hardware and an actual data connection? If not, do you have any other suggestions that might help in this situation? I've contacted Novatel Wireless via email and their developer forum, but have not received a response. Thanks!

• iPhone Text entry with completion and DONE button (not search)

  - by Adam Jack

  Using iPhone SDK 3.0, I wish to allow text entry with (optional) completion options that appear as typing is occurring, i.e. also allowing freeformat entry. As such I am using a UISearchBar (which has the text change events) and a UISearchDisplayController to present options. The problems is I want the DONE button to say DONE and not SEARCH, however I cannot find a way to set that. Clearly I feel I am missing something, or Interface Builder of the SDK API would have some property to set. I have seen other apps (in the store) that have achieved the result I want (free format entry, completion, DONE button) so maybe there is an alternative approach I am missing. Thanks in advance for any pointers.

• Android application chrashes after "share" intent

  - by Johe Green

  Hi, My app offers a "share/tell-a-friend" function. When the "share" button is pressed the following method is being called to open a list of apps, which can perform the action (Eg. Gmail, Twittroid, Facebook...): public void share() { Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND); shareIntent.setType("text/plain"); shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getText(R.string.menu_share_subject)); shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, getText(R.string.menu_share_body)); startActivity(Intent.createChooser(shareIntent, getText(R.string.menu_share_intent))); } The sharing functionality works basically. But when the sharing app (Facebook, Twitter, ...) tries to return to my app, a force close is thrown. I guess that my app gets closed in the background during the sharing process... at least that is what the debugger sais... Any ideas?

  - by noflipes

• iTunes Connect: Excluding iPad From Supported Devices

  - by mattmccomb

  I have just uploaded my first app to iTunes Connect and noticed that my list of supported devices is appearing as follows... Device Requirements : Compatible with iPhone, iPod touch, and iPad. I've developed specifically for the iPhone and iPod Touch and have not yet done any testing on the iPad simulator. I therefore don't want the app submission testers to try running my app on an iPad and rejecting it because of some minor issue. I've looked at setting the required device capabilities in my info.plist, but that doesn't appear to allow me to restrict at a device level. Is this a by-product of building using the 3.1.3 SDK? Are apps built using this SDK automatically upscaled to work on the iPad?

• iPhone Push Notification Reliablity

  - by David Beck

  How reliable do you find push notification on the iPhone to be? Does it improve when moving from the sandbox to production server? I am testing (with the sandbox of course) and have found that notifications are often delayed or not received at all. I am not talking about sending multiple messages and only the last one arriving, as the documentation indicates, but any notification never showing up. Also, I noticed that if I send a notification with an alert, and then send one with just a badge number, that the second notification will close the alert even after it's already opened. Does this happen between apps as well? For instance, if I send an alert for my app, and then the Facebook app sends a badge, will the Facebook badge close my alert window?
