QT 5.2 Beta 部署 QTQuick 到 Android 失败：json 文件无效

Question

I am trying to deploy one of the QT Examples (ie calqlatr or samegame) to my Android Phone (4.0.4). I am using Windows 7 32Bit and QtCreator 3.0.0Beta. I successfully added the device and the kits to deploy it to QtCreator.

The build of the example succeeds as well but during the deployment I get the following error:

Invalid json file: C:/Qt/Qt5.2.0/5.2.0-beta1/mingw48_32/examples/quick/demos/build-samegame-Android_für_armeabi_GCC_4_8_Qt_5_2_0-Debug/android-libsamegame.so-deployment-settings.json
08:18:32: Der Prozess "C:\Qt\Qt5.2.0\5.2.0-beta1\android_armv5\bin\androiddeployqt.exe" wurde mit dem Rückgabewert 2 beendet.
Fehler beim Erstellen/Deployment des Projekts samegame(Kit: Android für armeabi (GCC 4.8, Qt 5.2.0))
Bei der Ausführung von Schritt 'Deploy to Android device'

I checked the named json file and it looks ok for me:

{
 "description": "This file is generated by qmake to be read by androiddeployqt and should not be modified by hand.",
 "qt": "C:\\Qt\\Qt5.2.0\\5.2.0-beta1\\android_armv5",
 "sdk": "C:/adt-bundle-windows-x86/sdk",
 "ndk": "C:\\Users\\mcc-lan\\android-ndk-r9b",
 "toolchain-prefix": "arm-linux-androideabi",
 "tool-prefix": "arm-linux-androideabi",
 "toolchain-version": "4.8",
 "ndk-host": "windows",
 "target-architecture": "armeabi",
 "application-binary": "C:/Qt/Qt5.2.0/5.2.0-beta1/mingw48_32/examples/quick/demos/build-samegame-Android_für_armeabi_GCC_4_8_Qt_5_2_0-Debug/libsamegame.so"
}

As there is no further error description I don't have a clue where to go next. I also have a slight uncertainty in the Android NDK, I downloaded and used: android-ndk-r9b-windows-x86.zip is that correct or do I need android-ndk-r9b-windows-x86-legacy-toolchains.zip ?

Thank your for any suggestions.

Answer 1

Ok, I'll answer the question myself. Sorry for that.

After some even more research I realized that the Problem was due to lengthy paths.

The default build path from QTCreator made Windows to fail during some command-line calls. I changed the build-paths to short directory names and everything succeeded.

Best regards.
