Deploy Qt3D project for Android under win 7 - qt5

I've successfully deployed the cube example APK by creating a new Quick 2 project and copy qml file there, but got "module "Qt3D" plugin "qthreedqmlplugin" not found" error message, any clue for this? I already place the so file into imports/Qt3D folder, but no success. Thanks.
Edit: I tried using Qt 5.1.1 and followed the Qt3D installation described here (http://qt-project.org/wiki/Qt3D-Installation) , and can get rid of the plugin not found error message above. But, this time, a message of “library “libQt53DQuick.so” not found” show up as follows:
W/Qt (29930): assets:/qml/3dCube/main.qml:2 (): assets:/qml/3dCube/main.qml:2:1: plugin cannot be loaded for module "Qt3D": Cannot load library /data/data/org.qtproject.example.test3D/qml/Qt3D/libqthreedqmlplugin.so: (Cannot load library: soinfo_link_image(linker.cpp:1635): could not load library "libQt53DQuick.so" needed by "libqthreedqmlplugin.so"; caused by load_library(linker.cpp:745): library "libQt53DQuick.so" not found)

The problem been solved! After adding the following line in my .pro file:
QT += qml quick 3dquick
The example works well in my sony android phone with adreno gpu, but not in my new lenovo yoga 8" with PowerVR gpu which I'll look into later.
Edit: BTW I eventually use QT5.2.1 for building my example.

That's because in Qt 5.3 there was no way to figure out the plugin dependencies of qml imports. In 5.4, we have the qml import scanner that avoids the need to edit your .pro files to mention qml import dependencies.

SideBySide issue with ArcGISRuntime SDK version100.11

Trying to update my WPF application from the ArcGIS Runtime SDK version 100.6 to 100.11. I used the existing style in the WiX package to update the dll's so that all I had to do was ensure all the shader .cso files were accurate in the Components. Here is the screen shot of my dll's that are configured:
When I try to run the application, I get an error that it cannot access the RuntimeCoreNet100_11.dll. In the Event Viewer I get the following message:
In running the SxsTrace program, for the runtimecoreAssembly, it states the Parser "Did not find manifest for culture Neutral".
Any help here would be very appreciated.
Update
per the instructions given in the comment, i added the manifest file to the dependency components in the component group pictured above. this allowed my app to start, but immediately crashed with a KERNELBASE.dll error. Anyone familiar with fixing those?
Looks like you're missing the manifest files. There should be 4 files to deploy to each clientXX folder: runtimecore.dll, runtimecoreAssembly.manifest, RuntimeCoreNet100_11.dll and RuntimeCoreNet100_11.WPF.dll

Not able to show image (API setDrawIcons() not found error)

I am using MPAndroidChart in our android project to show graph and it's very helpful. Using latest version 3.0.1 (https://github.com/PhilJay/MPAndroidChart#usage)
I have some requirement to show image on top of BarEntry after some condition met. Same is working in example code downloaded.
BarDataSet set1;
set1.setDrawIcons(true);// Cannot resolve method 'setDrawIcons(boolen)
Why the above API is not part of library MPChartLib, am I missing something here?
Above problem got solved after integrating MPChartLib source code.
File -> Project Structure
click plus button to add New Module
Import Gradle Project
from Source directory: and finish.
The setDrawIcons method was added in 3.0.2. Change your Gradle option to read compile 'com.github.PhilJay:MPAndroidChart:v3.0.2'

Trying to convert iOS project using WinObjC, but getting missing sys/types.h error

I'm running ....\bin\vsimporter.exe (with default settings) in my project folder and the .sln file seems to build successfully, but when I try running the simulator (on Win32 Solution Platforms, debug build), I get a bunch of errors. Most of the errors involve a missing file from the iOS 8.4 SDK (sys/types.h):
Error unknown argument: '-Xanalyzer'
Error 'sys/types.h' file not found
Error unknown type name 'XSym'
Am I supposed to include the iOS8.4 SDK? Any help/suggestions would be great.
I had the types.h problem too. Try to manually retarget to the Win 10 SDK:
Right-click on the solution and hit retarget, select the latest Win 10 SDK from the list, select all projects and click ok. The types.h problem should be gone.
Retarget answer worked for me to get rid of the errors with missing header files.
To get rid of the -Xanalyzer issue, I removed it from the .vcxproj file as a command line option using a text editor.
For the pods, I manually copied them from a Mac that already had them downloaded.

dlopen() error image not found

I have software that first loads a .dylib lets call libFirst.dylib using the following command:
void* handle = dlopen(path.c_str(), RTLD_LAZY | RTLD_GLOBAL);
Later on inside a function from the loaded libFirst.dylib I attempt to load another .dylib using the same command but for libSecond.dylib, the loading of this shared library gives me the following warnings in my Xcode console:
error warning: Ignored unknown object module at 0x129310 with type 0x8a8399
dlerror: dlopen(/path/libSecond.dylib, 9): Library not loaded: libFirst.dylib
Referenced from: /path/libSecond.dylib
Reason: image not found
What I don't get is that its says libFirst.dylib is not loaded but I am currently inside a function from libFirst.dylib, so how can this be?
All my paths in DYLD_LIBRARY_PATH appear correct too.
Thanks in advance, I have been stuck on this for days.
I ended up using -install_name to change the install name of all my libraries to #rpath/dylibName.dylib and then in Xcode I set the Runpath Search paths using #loader_path to find all my .dylibs that I was using.
use:
install_name_tool -id #executable_path/../Frameworks/mylib.dylib mylib.dylib
then check it with:
otool -D mylib.dylib
I think an easier way to get around this error would be to revert to an earlier version where you were not getting this error. Right click on the project folder and navigate to local history to revert to an earlier version. I verified this to be working on the android studio installed on Mac OS Big sur.

ClassNotFoundException on app startup (on device)

I have been able to run my app exactly ONCE on the device (N8). Since then I always get a ClassNotFoundException when I launch it. It goes like this:
ClassNotFoundException:
com.greencod.pinball.nokia.PinballMIDLet
at java.lang.Class.forName at
...rtCldc.loadApplicationClass at
...rt.jvm.loadApplicationClass at ...
Invoker.handleStarRequest at
...l.rt.midp.MidleInvoker.run at
java.lang.Thread.run
Note that the app runs fine on the emulator. Also, the first time that it ran was througth the debugger in eclipse. Now the debugger or a plain install doesn't produce an app that can run. I am new to Nokia development, so I must be doing something stupid, I just don't know what :) I am using the Symbian^3 SDK 0.9.
To get the application on the phone, I click 'create package' from the manifest view, which build the jar/jad files for 2 targets: SymbianEmulator and SymbianDevice, which I installed by scanning the SDK folder. After I have tried uploading the file to the device by dropping it in the Install folder, by using the debuger in eclipse and with the Ovi program on my computer. The phone itself is configured to accept unsigned application.
I am quite lost and any help is welcome.
Additional Info
Eclipse is building the jad for me, so I'm not sure that is the problem. Here is the jad file:
MIDlet-1: Pinball Deluxe,,com.greencod.pinball.nokia.PinballMIDLet
MIDlet-Jar-Size: 1882
MIDlet-Jar-URL: Pinball-MIDLet.jar
MIDlet-Name: Pinball Deluxe MIDLet
MIDlet-Vendor: GreenCod
MIDlet-Version: 0.1.0
MicroEdition-Configuration: CLDC-1.1
MicroEdition-Profile: MIDP-2.1
Navi-Key-Hidden: true
Nokia-MIDlet-App-Orientation: portrait
Nokia-MIDlet-On-Screen-Keypad: no
And here is my class declaration:
package com.greencod.pinball.nokia;
import javax.microedition.lcdui.Display;
import javax.microedition.midlet.MIDlet;
public class PinballMIDLet extends MIDlet { ... }
It has been solved: nokia forums. Basically the problem was that the build.properties of the project were messed up.
