sdk interview questions
Top sdk frequently asked interview questions
I want to install SDK 4.3 in xcode 4.4 on mountain lion (os x 10.8), but when I installed the 4.3 sdk package from xcode 4.1 and launched the simulator from xcode 4.4, the simulator just told me that the ios simulator could not find the sdk.
The sdk may need to be reinstalled, which means it couldn't run! What's wrong with xcode 4.4 GM?
Are there any ideas about how to solve this kind of problem?

I want some examples. I always get confused, so with some examples I might be able to figure it out better.
Also: Is Eclipse an API or IDE?

I want to change the minimum SDK version in Android Studio from API 12 to API 14. I have tried changing it in the manifest file, i.e.,
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="18" />
and rebuilding the project, but I still get the Android Studio IDE throwing up some errors. I presume I have to set the min SDK in 'project properties' or something similar so the IDE recognises the change, but I can't find where this is done in Android Studio. Pointers greatly appreciated. Thnx.

In a UINavigationController-based iPhone app, in a method I would like to perform the programmatic equivalent of the back button being pressed and going back a view.
i.e. automatically press the Jobs button as seen here:
Is there a generic iOS call I can make, or is more information required?

I have CentOS 5, but I don't know the steps to install Java SDK on Linux.
Where to download the RPM file and what can I do next to fully install that.
Then I need to install Tomcat.
Or is there any ready-made package for all?

I have quite a few controls scattered throughout many table cells in my table, and I was wondering if there's an easier way to dismiss the keyboard without having to loop through all my controls and resigning them all as the first responder. I guess the question is.. How would I get the current first responder to the keyboard?

Lately Google and Intel have published a new way to run the emulator, which should work much better than the previous version (which has emulated ARM CPU). Here are some links about it: this and this.
However, after installing the new components and creating a new emulator configuration as instructed, I get an error and I also can't see any improvements. I've tried both API 10 and API 15, and with GPU enabled and disabled. None of those configurations helped. I've also tried it on two different computers and didn't get any boost (and got the same errors).
It seems that on the posts I've read about it, nobody had any problems with it and all report a much faster emulator.
The error it shows is:
emulator: Failed to open the HAX device!
HAX is not working and emulator runs in emulation mode
emulator: Open HAX device failed
Why is it happening, and is there a way to fix it? Is there anyone else who gets those errors or vice versa?
By the way, I have an Intel CPU, if that could be a problem.
EDIT:
here's what I see in the BIOS, so it should be available... :

How can I add 2 buttons into the UINavigationBar without XIB?
The 2 buttons should be aligned on the right side of the UINavigationBar.
I know how I can add one button, but how about two?
