I removed android:theme from AndroidManifest.xml:
<activity android:name="net.geographx.MainActivity"
android:configChanges="orientation|uiMode|screenLayout|screenSize|smallestScreenSize|layoutDirection|locale|fontScale|keyboard|keyboardHidden|navigation|mcc|mnc|density"
android:label="@string/app_name"
android:theme="@style/AppTheme"
android:launchMode="singleTask"
android:screenOrientation="portrait"
android:exported="true">
<!-- Splash screen -->
<meta-data android:name="android.app.splash_screen_drawable" android:resource="@drawable/splash"/>
<!-- Splash screen -->
Found an implementation here and added two pixels:
import QtQuick
import QtQuick.Controls
import QtQuick.Layouts
Menu {
width: {
var result = 0;
var padding = 0;
for (var i = 0; i < count; ++i) {
var item = itemAt(i);
result = Math.max(item.contentItem.implicitWidth, result);
padding = Math.max(item.padding, padding);
}
// It looks like two pixels are missing to remove the ellipsis.
// My first idea was that it is leftInset + rightInset, but it does not work.
var missing = 2;
return result + padding * 2 + missing;
}
}
From QT’s Purchasing:
//SKProductsRequestDelegate
-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
NSArray<SKProduct *> *products = response.products;
SKProduct *product = [products count] == 1 ? [[products firstObject] retain] : nil;
if (product == nil) {
//Invalid product ID
NSString *invalidId = [response.invalidProductIdentifiers firstObject];
QMetaObject::invokeMethod(backend, "registerQueryFailure", Qt::AutoConnection, Q_ARG(QString, QString::fromNSString(invalidId)));
} else {
//Valid product query
//Create a IosInAppPurchaseProduct
IosInAppPurchaseProduct *validProduct = new IosInAppPurchaseProduct(product, backend->productTypeForProductId(QString::fromNSString([product productIdentifier])));
if (validProduct->thread() != backend->thread()) {
validProduct->moveToThread(backend->thread());
QMetaObject::invokeMethod(backend, "setParentToBackend", Qt::AutoConnection, Q_ARG(QObject*, validProduct));
}
QMetaObject::invokeMethod(backend, "registerProduct", Qt::AutoConnection, Q_ARG(IosInAppPurchaseProduct*, validProduct));
}
[request release];
}
I simply opened arboreus_examples/qt6/CMake/UsingSwift/UsingSwift_v3/CMakeLists.txt in QT Creator and was able to build it and run.
In its main.cpp it creates a Swift wrapper and calls method:
ASwift* oSwift = new ASwift(&oEngine);
oSwift->mInit();
_A_DEBUG << oSwift->mString();
When I switched to QT 6.7.2 and set QT_ANDROID_TARGET_SDK_VERSION "34" (that is Android 14) my QT app started to crash with the following stack traces:
