Android emulator does not emit a signal
I'm currently on a test project and I'm using the KVM Android Emulator.
BEHAVIOUR: when I run the code, the app gets correctly opened in the phone emulator but then it no longer responds.
PREAMBLE: I checked if all Qt connects are correctly performed by declaring them as bool, and then I had the value printed
const bool connected = connect(myObject, SIGNAL(mySignal()), myClass, SLOT(mySlot());
qDebug("connection is %i", connected);
In all cases the connects were OK.
HINT: by using the breakpoints I noticed the debugger never entered one particular slot. This slot should be called every time the signal readingChanged() is emitted by an object of type QGyroscope(), which belongs to the Android emulator.
HYPOTHESIS: it is likely that the Android emulator does not emit one or more signals related to the Gyroscope. If you simply want to have the values measured by the Android emulator printed on the emulator itself, you will find out you can. However, the signals associated with these values are never emitted.
QUESTIONS:
1) How can I check if a signal with a void argument is actually emitted?
2) Is there a fix for a signal not emitted by the Android emulator?
Thanks in advance. Any hint is welcome
