[SOLVED] Qt 5.1 Installation Problem (for Android)
I want to make a program on Android. So I download the Qt 5.1 Windows 32bit Mingw. I did step by step what "that page":http://doc-snapshot.qt-project.org/qt5-stable/qtdoc/android-support.html says. "This page":http://qt-project.org/doc/qtcreator-2.8/creator-developing-android.html says I should do somethings in Package configurations. I cant found "Package configurations". Where is that?
I'm not answering with any specific expertise, just my experience when I installed Qt 5.1.
This may not solve your problem, but hopefully it will move you further along.
In the QT folder you will find an executable called "MaintenanceTool" or I guess if you are on Windows "MaintenanceTool.exe".
If you run that you will get three options:
Package Manger (which lets you add and remove components) which includes options for Android.
Update Components (which is generally worth doing).
Remove All Components (which you probably don't want to do.
My suggestion is to make sure you have the Android components installed.
I can't help any more than that, my only Android development was a little playing in Java using Eclipse, that didn't amount to anything worthwhile.
You have a desktop project and probably didnt install the qt for android version
Yeah, you need to make sure you very closely follow all the instructions for getting Android to run. For instance, I thought I had the right JDK installed, but I didn't and it lead to all sorts of headaches. You're sure you have all the Requirements mentioned in the Qt Creator page?
BTW, your picture is of the Build, not the Run configurations. Click the Run button near the top, next to Build, to see the Android configurations.
As I already mentioned, he wont get any android configurations on his current setup. It is clearly a Desktop project, not android. Btw, the run tab is correct on the picture. Thats not build :P
Yes You totally right. I downloaded wrong Qt version. I download Qt for Android (Windows 32Bit)
When I debug the a example of Qt on Android for x86 (GCC 4.4.3, Qt 5.1.1), "Create new AVD" window appears. I write the name and I press the OK Button. I get the error text.

My Android Settings
What should I do?
I dont know exactly if it makes any difference, but you are using the x64 android NDK and not the one for x86/32bit. You could try this one
You could also update your java version, more for security reasons :)
You found a good point. I download x86 NDK and problem doesnt still solve
Now I can start the Android Simulator. But My program is not working on simulator. Simulator starts and only show the main android screen.
Dont you have a real device to test it?
The android emulator has problems with Qt.

How can I connect my android phone with Qt? I find something below. There is a page that explain how to do that but I cant do that.
What is your device? Maybe its android API level is too low.
I have a Samsung Galaxy Note 2. My android version is 4.1.2. I download my computer the android 16 and 17 API.
The Qt project should be android level 16 then. 17 wont work.
Btw, you have for sure enabled usb debugging in the android developer options?
Yes Usb Debugging is opened. I cant understand why dont we fix? :(
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.
I got the text;
@List of devices attached
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.
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?
Yes I know. I use Windows 7.
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
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
I guess I should wait the Qt 5.2 for more stable. Emulator has a bug, yes. Why dont i connect my phone? :(
Same goes for you. I also posted in the other thread. You have spaces in your folder structure.
Remove the space in Android SDK-NDK
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.
What is the rest of the log to maybe see at which step it fails?
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?
