Hi,
I'm pretty sure that I'm missing something fairly basic...
Our Android Qt app registers its desire to be opened when a certain type of
USB device is plugged into the Android phone / tablet:
AndroidManifest.xml:
...
<intent-filter>
<action
android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
</intent-filter>
<meta-data
android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
android:resource="@xml/device_filter" />
...
The xml/device_filter.xml file is setup to list the devices that we want
to respond to.
Now if the user plugs in such a device, an Android system message pops up
and asks if they want to launch our app. Awesome, exactly what I want.
Here comes the question - inside the app, how do I know that I was
launched by that intent? And how do I get to the extra data that is
available through that intent?
Andrid docs tell me
(https://developer.android.com/guide/topics/connectivity/usb/host) that in
Java all I need to do is:
UsbDevice device = (UsbDevice)
intent.getParcelableExtra(UsbManager.EXTRA_DEVICE);
and now I can get the deviceName, PID and VID for that device...
But how do I do this from a Qt app?
I found the documentation here http://doc.qt.io/qt-5/qandroidintent.html
but that still doesn't tell me how I know that I have received an intent
and how to get the Java intent object.
Because once I know that I think I should be able to get to that info via
QAndroidIntent::extraVariant(const QString &key) ...
Does someone have a working example of how a Qt Android app can respond to
a USB device being plugged in? Or any other pointers to working code?
Thanks
/D
