Since we support QString and QList specializations, we should also
support QStringList directly. That's a bit more involved as we need
to specialize the code path for QString, which is not convertible to
or from jobject. But once we have mapped the type to jstring it
follows the implementation for lists of objects.
We now need to generate temporary local references when
converting a QString to a jstring, so manage a local frame. We do
so explicitly in chunks of 100 local references.

QObject::startTimer() returns 0 in case of failure, for example when
someone tries to register a timer with a negative interval.
However, QTimer internally uses -1 as an invalid timer id.
This could lead to a situation when the timer was not really started,
but QTimer::isActive() returned true.
This patch fixes it in two ways:
- check the return value of QObject::startTimer() and treat 0 as an
error.
- do not treat 0 as a valid timer id when calculating the active state.
As a drive-by: move the `using namespace std::chrono_literals;`
declaration to the top of tst_qtimer.cpp, so that we do not need to
repeat it in each test case.

This changes takes Qt for Android Java code away from the Delegate
classes that uses heavily Java reflection to invoke Activity/Service
calls and overrides. So instead of that, now, we have a QtActivityBase
and a QtServiceBase classes which handle the override logic needed for
Qt directly without reflection.
These Base classes extend Android's Activity and Service directly, and
are inside the internal Qt android package (under Qt6Android.jar).
For example, to handle onConfigurationChanged, instead of the current
way where we need this in QtActivityDelegate:
public void onConfigurationChanged(Configuration configuration)
{
try {
m_super_onConfigurationChanged.invoke(m_activity, configuration);
} catch (Exception e) {
e.printStackTrace();
}
handleUiModeChange(configuration.uiMode &
Configuration.UI_MODE_NIGHT_MASK);
}
And then this in QtActivity:
@Override
public void onConfigurationChanged(Configuration newConfig)
{
if (!QtLoader.invokeDelegate(newConfig).invoked)
super.onConfigurationChanged(newConfig);
}
public void super_onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
}
And having to keep it's Method handles around and then use Java
reflection
to call the override behavior done by Qt and the superclass methods.
instead of that, we can do it now in QtActivityBase like:
@Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
handleUiModeChange(newConfig.uiMode &
Configuration.UI_MODE_NIGHT_MASK);
}
Then, we would still have our user facing QtActivity class which extends
QtActivityBase and benefit from the same implementation of Qt logic done
in the base class.
An additional benefit to this approach is that now QtActivity will be
very lightweight and doesn't need to have all the boilerplate code as
before.

To fix that, register the native function via a proxy that is a variadic

Constructing such objects means constructing a Java object of the class
the object type represents, as per the Q_DECLARE_JNI_CLASS declaration.
This is not without ambiguity, as constructing a type with a jobject
parameter can mean that a type wrapping an existing jobject should be
created, or that a Java object should be created with the provided
jobject as the parameter to the constructor (e.g. a copy constructor).
This ambiguity is for now inevitable; we need to be able to implicitly
convert jobject to such types. However, named constructors are provided
so that client code can avoid the ambiguity.
To prevent unnecessary default constructed QJniObjects that are then
replaced immediately with a properly constructed object, add a protected
QJniObject constructor that creates an uninitialized object (e.g. with
the d-pointer being nullptr), which we can then assign the constructed
jobject to using the available assignment operator. Add the special
copy and move constructor and assignment operators as explicit members
for clarity, even though the can all be defaulted.
Such QJniObject subclasses can then be transparently passed as arguments
into JNI call functions that expect a jobject representation, with the
QtJniTypes::Traits specialization from the type declaration providing the
correct signature.
QJniObject's API includes a lot of legacy overloads: with variadic
arguments, a explicit signature string, and jclass/jmethodID parameters
that are completely unused within Qt itself. In addition the explicit
"Object" member functions to explicitly call the version that returns a
jobject (and then a QJniObject). All this call-side complexity is taken
care of by the compile-time signature generation, implicit class type,
and template argument deduction. Overloads taking a jclass or jmethod
are not used anywhere in Qt, which is perhaps an indicator that they,
while nice to have, are too hard to use even for ourselves.
For the modern QtJniTypes class instantiations, remove all the overhead
and reduce the API to the small set of functions that are used all over
the place, and that don't require an explicit signature, or class/method
lookup.
This is a source incompatible change, as now QJniTypes::Object is no
longer a primitive type, and no longer binary equivalent to jobject.
However, this is acceptable as the API has so far been undocumented,
and is only used internally in Qt (and changes to adapt are largely
already merged).

If we construct the QJniObject from a jobject, then we know the jclass,
but not the class's name. If className is called while the stored name
is empty, get the name of the jclass and updated the stored value.
