Android App via debugger cashes updateNativeActivity() not found

Andy314

Hello, I an on the way to my first Android app with Qt.

Buildings and Deploying seems to work. I get the following message in the output page:

E/ample.TestQMake: No implementation found for boolean org.qtproject.qt.android.QtNative.updateNativeActivity() (tried Java_org_qtproject_qt_android_QtNative_updateNativeActivity and Java_org_qtproject_qt_android_QtNative_updateNativeActivity__) - is the library loaded, e.g. System.loadLibrary?
E/ashmem  : Pinning is deprecated since Android Q. Please use trim or other methods.

I use windows Qt 9.6.0 Clang x86_64.

It is the simple QWidget App created from the New Project Wizzard of the creator.
Only a MDI window. Can I run such apps as test on Andriod or must I make something with Activitys ?

Here is the full output:

Hi

first, QtQuick is recommended for Android and iOS over QtWidget which isn't optimal for those platforms.

I have serious doubt about MDI window on Android platform (iOS also). Android is not intended to open multiple windows at once and I just wonder whether windows inside window could be the actual cause of your issue.
I haven't made much mobile development with Qt but as far as I remember, android simulator has to be configured in 32 bits instead of 64 on older android versions, which might explain the "unexpected cpu variant for x86" message ?

No, you do NOT need to write any Activity related code to create an app for Android.

Yes you are right, MDI makes no sense here. I have a tablet app (with widgets!) that runs on a windows tablet very well. Now, I want to transform it to an Andriod app.
The current app ist only for testing, as the simplest gui app the creator creates automatically.

The hint about the 32 is interesting, I will I will investigate it further, before I answer.

The CPU hint seem to be no the problem. Its only a warning I found in the net. Because I take a newer Android is all 64 bit.

It is not really correct, what I wrote, that it is my first Android app - its my first I really will use.
When I began with QT - nearly 7-8 years ago - I had a large Windows Desktop Programm and made and try only for testing to let in run in Android. After about 3 day it worked and I was very impressed of it, how easy it was and how similar the gui looks (and in my favourite language C++).
Indeed I had a MDI Main Windows with menü etc. All was very small, so could not work by touch with but with the mouse all works like a normal windows desktop app. MDI Chield creates Qt in its onw way, that must not be OS-Windows, it think.
