[SOLVED] Qt 5.1 Installation Problem (for Android)
-
There might be a problem with your adb/usb drivers.
Can you open a shell/cmd, go to your android sdk folder, then platform-tools and type in "adb devices". Your phone should be connected. If it gets recognized, you will see the device there. If its not there, then there might be some driver problems.

You got good point. I moved the SDK and NDK to different folder. I changed android settings on Qt (SDK and NDK locations). I have a weird error. I got the error when I build. How can I fix?

I found something.
If I dont connect my phone and I build the project, Android Emulator starts and it waits main screen.
!http://k1308.hizliresim.com/1d/2/r1hsd.jpg(qt)!If I connect my phone, I got the @ :-1: error: SDK-NDK\ndk-x86\android-ndk-r9/platforms/android-14/arch-arm/: No such file or directory@ error

I would recommend to try it on a linux distribution. Qt5.1 seems to be more stable on linux.
Or maybe try some older ndk: http://dl.google.com/android/ndk/android-ndk-r8e-windows-x86.zip

Here they are... We finally found the solution.
I fix the "install_target error" error. Cause of the error is spaces in my folder structure. My project's location is D:\Other\C++\Qt\my codes. I change the D:\Other\C++\Qt\my-codes. We should never use spaces.
Secondly, I have a layout problem. "Merhaba Dünya :)" label has a big background, you see. How can I do screen that like Windows (I mean similar windows)? Is there any article for Android Widget/Layout system on Qt?
