Hallo experts, I've tested what's happing with my app when the iPhone is switched off while the app is active. For this purpose I logged the callback methods of the app's lifecycle in the xcode debugger console.

I read in another post that you can submit the app without the binary but I based on what I have seen this is no longer possible. It seems you cannot submit without the binary and the binary is submitted through the application loader. Is there any other known way to get the itunes/app store link to my app before I submit the binary?

I want to know if there is a way to restrict the size or movements of the UIViews in the GestureRecognizers. Sure I could write my own restriction code but wana know if we can set some property or something to have some bound limits.

I'm trying to test an app I'm developing on my iPhone. To do that I changed the target from Simulator to Device on Xcode. The application is correctly uploaded to the device and it works, or better, the main view is shown but if I try to open a secondary view, application crash.

It appears that all the touch methods of a UIView are only called if the touches began within the bounds of that view. Is there a way to have a view respond to a user who has touched outside the view, but then dragged his fingers into the view?

We have a great software foundation based on Microsoft MVC 2, Entity Framework 4, Repositories, POCOs, Service and Control layers, C# Views, JQuery and html. Firefox pulls 100 records in 250 ms, drops it in to a template, links the data to the markup, and we sit back and drink margaritas.

So, I've been messing around with the Facebook iOS SDK for a bit and as of the latest version I can't get the fbDidLogin method to be called. The login process works fine, with Safari used on the simulator and the Facebook app being used when running it on a device. However, after logging in I get transferred back to my app (as I should be) but as the fbDidLogin method hasn't been called, nothing has changed. As far as my app is concerned I'm not logged in. The demo app that is bundled with the SDK works fine. So I'm obviously doing something wrong, but I have no idea how to check what. I triple-checked all the methods used in the demo app against my own and as far as I can see everything looks the same. Any thoughts or ideas on how to debug this? Or has anyone had similar problems?

I would like to change the color behind the flip from white to a different color or picture. Is that possible?

iOS SDK 4.2 includes a new UIApplicationDelegate method called application:openURL:sourceApplication:annotation: . It is a replacement for application:handleOpenURL: and offers more information about the calling application: not only do we get the bundle identifier of the calling app, but also, in the annotation argument,

I'm thinking of upgrading to iOS SDK 4.2. But what I'm wondering is if I'll still be able to run the simulator as iOS 3.2. This is because I'm creating iAds for iPad but I still want to check if my program will run with iOS 3.2.

I'm trying to use the ActionBarSherlock library to provide backwards compatible ActionBar support with tabs in my Android app, so I downloaded the latest build, built the demo, and ran it.

When I switched from my debug map key to my signed map key my maps stop working. I get the following errors in logcat:

Some apps in the Android Market have a Top Developer badge under their name. For example: Facebook for Android .

Within the last days I do see increasing error messages that sound identical. I don't use tablets ActionBar - I'm developing for phones only.

I'm trying to enable hw acceleration in Honeycomb, and display some Bitmaps on Canvas. All works fine, but for large bitmaps (>2048 in one dimension), I get error in log:

I can't find good docs on PopupWindows showAtLocation and Gravity. After hacking for a few hours trying some black magic maths to calculate centers and try to align the view using Gravity.TOP I found a post that used Gravity.CENTER. I'm collecting my findings here in the hopes it saves someone else some pain.

I've been working on push notifications and I am able to implement it and display it on status bar, the problem I am facing is that I want to display it even if the phone is lock, Under the lock screen where it says ("drag to unlock"), I have seen notifications like that but cant find any example to that.

I am using AsyncTask and wondering what are the implications of passing the arguments to the constructor instead of passing them directly on the execute() call to the doInBackground(...) method, for example:

So I am thinking of getting Sprint Nexus S from ebay to do android development. I am wondering whether getting a locked phone will hinder me from doing any kind of development work on the phone (pushing to app market, connecting to internet(i don't care about 3/4G as long as I can use wifi I am good)). What are some things that I should be worried about when getting a locked phone for development? Will the locked phone even run without SIM?

After adding Google Guava r09 to our Android project the build time increased significantly, especially the DEX generation phase. I understand that DEX generation takes all our classes + all jars we depend on and translates them to DEX format. Guava is a pretty big jar around 1.1MB

I'm getting user reports from my app in the market, delivering the following exception:

I use anti aliasing to make my images more smooth. When using anti aliasing a dark border will be drawn around the images. This happens because Android uses the color black and mixes it with the yellow from the images. This is a gernal problem! When I draw a rectangle and set the alpha value to 127 the image also gets quiet dark. Instead of using black Android should use white to draw the transparency.

Does anyone knows an alternative to Android's webview component ? For some reasons, it's functionality's are insufficient for me : I need to be able to catch every single request to some url, when i'm browsing a wml page (wap). Anyway, I need to be able to do stuff that Android's webview is not made for. I thought "hey, let's play with the source code, I'm pretty sure that webviews are using apache.org librairies to access internet". Oh boy was I mistaken. Webviews use native code, and that's where I'm stuck.

I just had a look at the google io video "memory management for android". Slides are available here http://dubroy.com/memory_management_for_android_apps.pdf . The memory leak example is on slide 36.

I have seen many similiar questions but no good answer despite some of them being accepted. I have registered for C2DM. I received confirmation email. Then I wrote some simple app to register for C2DM. I get the id (tried on emulator and on real device). Then I got the auth token (with curl) for my email that I used for C2DM registration (the same email that I use in app for acquiring the id).

I am using a method to combine two Bitmap Images and write in the SDCard . The App. works fine in the emulator, but when I tried to execute in on the Real Device it throughs Null Pointer Exception at this line cs = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888); that is to create a new Bitmap on which I will draw both the images that are to be combined using Canvas .

I've been using Log.whatever() calls to Log various bits of information as I've been developing my Android app. As I prepare to publish my app to the Android Marketplace, I'm trying to figure out what I need to remove.

I have recorded an array[1024] of data from my mic on my Android phone, passed it through a 1D forward DFT of the real data (setting a further 1024 bits to 0). I saved the array to a text file, and repeated this 8 times.
