[SOLVED] Qt 5.1 Installation Problem (for Android)

kingsta

I got the text;
@List of devices attached
4df7... device@

Note: "..." means its continuing

When I close the Usb Debugging Mode on my phone, I got only "List of devices attached" text.

I guess driver has no problem. Am I right?

Ye, thats good. But do you know what I just saw? You are using android for x86 and not armv7. Your note 2 has an ARM cpu and not x86.

kingsta

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?

Same issue like this guy, are you also on windows 8 maybe?

kingsta

Yes I know. I use Windows 7.

kingsta

I found something.

If I dont connect my phone and I build the project, Android Emulator starts and it waits main screen.

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

Moster

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

kingsta

I guess I should wait the Qt 5.2 for more stable. Emulator has a bug, yes. Why dont i connect my phone? :(

Moster

Same goes for you. I also posted in the other thread. You have spaces in your folder structure.
Android SDK-NDK\ndk-x86\android-ndk-r9
Remove the space in Android SDK-NDK

kingsta

I think You got the point. I changed the folder name Android-SDK-NDK. So If I connect my phone, I got the @:-1: error: [install_target] Error 1@ error now. If I dont connect my phone, I still see the main android screen.

Moster

What is the rest of the log to maybe see at which step it fails?

kingsta

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?
