Call C++ function from android BroadcastReceiver

[MajidKamali]

Hi.
I have an android application written in Qt. It has a BroadcastReceiver which receives incoming calls and shows a custom activity written in java.
Is it possible to call C++/Qt function and run native code, in that activity? How? (I want to access ciphered database from Qt)
Qt program may not be running while receiving BroadcastReceiver.

Thanks

You can call C++/Qt to native code with JNI, here is link to start
http://doc.qt.io/qt-5/android-support.html
and this is good example to start with Qt Android : http://doc.qt.io/qt-5/qtandroidextras-notification-example.html

I know how to call C++/Qt function from android.
But In this case Qt application is not running, while broadcast receiver receives signal from Android.

Hello.

See example:
Qt\Examples\Qt-5.7\androidextras\notification

Qt\Examples\Qt-5.7\androidextras\notification\android-sources\src\org\qtproject\example\notification\NotificationClient.java

This class extends
public class NotificationClient extends org.qtproject.qt5.android.bindings.QtActivity

In other words this is your activity , add BroadcastReceiver there.

Check that there is a change in AndroidManifest.xml

android:name="org.qtproject.example.notification.NotificationClient"

Where this class becomes its main activity.

I have helped .
