No rule to make target error while building for Android

[Awareness]

I am using Qt 5.2 and Qt Creator.I am trying to build a simple project for Android ,when I try to build an automatically-created widgets project,Qt Creator gives this error:


"06:56:53: The process "C:\Qt\Qt520\Tools\mingw48_32\bin\mingw32-make.exe" exited normally.
06:56:53: Configuration unchanged, skipping qmake step.

I have installed(or I think so) Android Sdk.When I run Android Sdk Manager it lists:

Android Sdk Tools - Rev 22.3 - installed
Android Sdk Platform-tools - Rev 19 - installed
Android Sdk Build Tools - Rev 19 - installed

Android 4.4(API 19):
SDK Platform - Api:19 - Rev 1 - installed
ARM EABI v7a System Image - Api:19 - Rev 1 - installed

Extras:
Android Support Library - Installed

The other components aren't installed

I downloaded ndk and extracted the files to a folder.
I downloaded and extracted Apache Ants to a folder.
I set a system variable called ANDROID_NDK_HOST : windows
I have set JAVA_HOME system variable to point jdk directory.
C:\Program Files\Java\jdk1.7.0_45

I added these to Path variable : %ANT_HOME%\bin;%JAVA_HOME%\bin;<MINGW_ROOT>\bin;%PATH%

Inside Qt Creator,I added:
Android SDK Location:C:\downloads\AndroidSdk\adt-bundle-windows-x86-20131030\adt-bundle-windows-x86-20131030\sdk


Android NDK Location:C:\downloads\AndroidNdk\android-ndk-r9b-windows-x86\android-ndk-r9b

It says:"Found 6 toolchains for this NDK."
"Automatically create kits Android tool chains" is enabled.
"Qt version for architecture mips is missing."

Ant location:C:\downloads\ApacheAnt\apache-ant-1.9.2-bin\apache-ant-1.9.2\bin\ant.bat
JDK location:C:\Program Files\Java\jdk1.7.0_45

While I am creating a new project,I select only one of the Android ones on kit selection menu.

Also I have another question too,do I have to connect an Android device to computer for building an Android application or not?

I solved the problem at last.

It seems like the problem was ndk directory's long name:
mingw32-make: *** No rule to make target '..\..\..\..\..\..\downloads\AndroidNdk\android-ndk-r9b-windows-x86\android-ndk-r9b\sources\cxx-stl\gnu-libstdc++\4.8\libs\armeabi-v7a\include\bits\c++config.h', needed by 'main.obj'. Stop.

When I copied ndk directory to c:\android-ndk-r9b instead of c:\downloads\AndroidNdk\android-ndk-r9b-windows-x86\android-ndk-r9b ,and after setting the new path under Qt->Tools->Options->Android , it built the project without problems.
