  • How to I make a navigation-based app?

    - by Dyldo42
    Yes, I know, most of you are thinking I'm an idiot, butt (kidding) I'm not. I've been searching everywhere for something on how to fully make a navigation-based iphone app, but all I've found is how to set up table views or navigation controllers. I haven't found anything on how to create a data model (something simple from arrays and dictionaries, SQLite and CoreData are a bit out of my scope) or navigate it. Does anyone know of any tutorials or anything like that? Thanks.

  • Why Camera.setParameters(Camera.Parameters) has no effect on Sony-Ericsson X10 and Droid?

    - by mobilekid
    Has anyone come across a strange behaviour with the Camera API when used on Sony-Ericsson X10 or Droid? For example the following code doesn't work on those devices. As a result I'm getting a lot of negative feedback on the Market translating into many cancelled orders... mParameters.set("rotation", orientation); mParameters.set("jpeg-quality", img_quality); mParameters.set("picture-size", "1024x768"); mCamera.setParameters(mParameters); Could you suggest an alternative way of achieving the same? Thanks.

  • API for configuring static IP addresses in an android application

    - by awoodland
    Is it possible to set the IP address of an interface in Android within an application? I can query the available interfaces and their current addresses using java.net.NetworkInterface, but this doesn't provide a facility to change these. Did I just miss something somewhere or is it not allowed? I was hoping to be able to make my application either change or add an alias to one or more of the existing interfaces at runtime on an "off the shelf" device. (2.1/2.2). Ideally I'd like to do this for both IPv4 and v6 addresses.

  • Click two buttons at the same time in Android

    - by sw333t
    I have two buttons that both have onTouchListeners and perform an action when pressed down. Why do they not work if you try to click both at the same time? I'm building for Android 1.6. I don't have a real device to test on, and you can't test clicking two things at the same time in the emulator. Thanks for any help.

  • iPhone app getting XML then refreshing it at intervals...

    - by user157733
    I have an app which gets some data from the web via an XML document. I have this working fine and have followed apples SeismicXML example (uses NSURLRequest etc). I am very new to this so I have to admit that I do not totally understand all the code that gets the XML - but it is working. My problem is that my app may be running for some time so I want to be able to refresh the XML every now and again and check to see if it is different. If it is different I need to update my contents. Basically this means my questions are.... Is there a standard way of doing this? I was thinking of creating a timer to call the function which parses the XML but I can't figure out which function to call. If anyone can give me any pointers or even better examples of this it would be fab. Thanks

  • Template apps for iPhone

    - by rob
    Is there a good place to get starter apps for iPhone, where you choose from any of a large set of permutations?...for instance with a nav bar and a flip screen and a 3 deep table view, with Core Data support etc. I guess what I was hoping for is some kind of wizard where you can check a few boxes and have a working app as a starting point....but more than just the 3 or 4 choices that come with xCode. If not a wizard, just a nice set of a couple dozen permutations. Also....is there any good sample apps out there that show the difference between identical apps, one which uses Interface Builder and one not? Aside from being handy for myself, I'd think these would be great as a teaching tool. I've googled a bit and come up with nothing.

    - by user312917
    I have alot of wav files stored in sqlite3, but when I retrieve one of them, I can't play it. The retrieve code is NSData *soundData = (NSDATA *)sqlite3_column_blob(statement, 0); mPlayer = [[AVAudioPlayer alloc] initWithData:soundData error:&error]; The data is stored as binary and it's there when I search for it using sqlite3.

Any ideas what I'm doing wrong?

  • Cannot change UIImageView frame in a custom table cell.

    - by jkally
    I have a custom table cell. In it I have put (via the IB) an image view of a certain frame In 'cellForRowAtIndexPath', under certain conditions, I would like to modify the frame of this UIImageView, so I write something like: UIImageView *imgv = (UIImageView *)[cell viewWithTag:1]; CGRect r = CGRectMake(20.0, 20.0, 10.0, 10.0); imgv.frame = r; But nothing expected happens (The frame does move a little though not to where I want, but doesn't change its size at all);

  • iPhone settings not honoured

    - by winsmith
    My iPhone app has the following problem: Freshly installed, when I read out my "Play Sound" preference with the following code: defaults = [NSUserDefaults standardUserDefaults]; NSLog(@"Play Sounds? %d", [defaults boolForKey:@"play_sounds_preference"]); The setting always reads out as false, even though the default setting is set to true. Any ideas? Here is my Root.plist: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>StringsTable</key> <string>Root</string> <key>PreferenceSpecifiers</key> <array> <dict> <key>Type</key> <string>PSGroupSpecifier</string> <key>Title</key> <string>General Settings</string> </dict> <dict> <key>Type</key> <string>PSToggleSwitchSpecifier</string> <key>Title</key> <string>Sounds</string> <key>Key</key> <string>play_sounds_preference</string> <key>DefaultValue</key> <true/> </dict> </array> </dict> </plist> When the user opens the Settings.app and navigates to my app's name, THEN the setting reads out as true, even if the user doesn't change anything.

  • Problem loading a contents URL into a string

    - by bebeTech
    I've been using this method for a few weeks now as suggested on my previous question and the app now keeps crashing with a Protocol 443 error - something about unable to resolve the address. Worked fine when first installed and then just stopped. The same with on the device itself, worked fine until this morning and now the same issue?? Nothing wrong with the URL as I can still load in a browser. If I leave it for a couple of days it starts working again?? Is there a more effecient way of using the Http POST and GET functions? All I am trying to do is perform a login and save the resulting page to a string. Is there a more Android friendly way?

  • How to sign an APK with more than one certificate?

    - by ddcruver
    How do I sign an APK with more than one certificate, so that I can do this when I publish to the Android Market: Version 1.0 = Signed with Certificate A Version 2.0 = Signed with Certificate A & B Version 3.0 = Signed with Certificate B The Android Market does give me some hope but I am not sure what to make of it, when I upload with a different sign certificate it gives me this message: "The apk must be signed with at least one certificate in common with the previous version." Motive: I have published an app on the market using the Android Signing Tool as part of MotoDev Studio for android. The problem is that it handles the keys itself and there is no way (documented) to get them. I want to change it to use a keystore and certificate that I have more control of and can use even if I don't use MotoDev Studio anymore. Also it seems that MotoDev Studio will lock you out of new features such as shared libraries.

  • android drawable changes sizes on screen when reading image from file

    - by Daniel Benedykt
    Hi I have an image on a private file. I read the file, create the drawable, and assign it to an ImageView. The ImageView has WRAP_CONTENT so the size is automatic. On 320x480 screens, the image looks good But on screens with more resolution and high density 480x800 or 480x854 (N1, droid) , when the image is for example 150x150, I see the image as 100x100. Of course it has something to do with the density but not sure how should I resolve this. This is my code: FileInputStream fis = this.openFileInput("icon.png"); icon = Drawable.createFromStream(fis, "icon"); fis.close(); imageView.setImageDrawable(icon); thanks
