+    \title Android Custom Activity
+    \ingroup examples-qtandroidextras
+    \example customactivity
+    \brief Demonstrates working with custom Android activities.
+
+    \image customactivity.png
+
+    This example demonstrates how to create an Android Activity and run it from
+    your Qt application. The activity is composed of a Java class and an Android
+    XML layout which is started from the main app. The activity can send back data
+    after finishing which can be used in QML.
+
+    When you click the \uicontrol{"Start custom Android activity"} button, the
+    activity is started, and the activity has a text view and a button to exit.
+    The activity can either use the button or the back gesture to go back.
+
+    \include examples-run.qdocinc
+
+    \section1 Create Activity Class
+
+    Define an Android class called \c CustomActivity in the CustomActivity.java
+    file as follows:
+
+    \quotefromfile customactivity/android/src/org/qtproject/example/activityhandler/CustomActivity.java
+    \skipto package
+    \printuntil /^\}/
+
+    The Activity's layout is defined at \e {customactivity/android/res/layout/second_activity.xml}.
+
+    To use this Activity, it must be defined in the \e AndroidManifest.xml file
+    as follows:
+
+    \quotefromfile customactivity/android/AndroidManifest.xml
+    \skipto :custom_activity
+    \printuntil </activity>
+
+    \note To use any native JNI calls, you must extend \c QtActivity instead of
+    \c Activity.
+
+    \section1 Start the Activity
+
+    To start an Activity from Qt, you need to create an intent using \l{QAndroidIntent},
+    then call \l{QtAndroid::startActivity} providing the intent, a custom request
+    code, and a callback function. The latter is called after the activity has
+    finished. You can start the activity as follows:
+
+    \quotefromfile customactivity/activityhandler.cpp
+    \skipto showSecondActivity
+    \printuntil });
+    \printline }
+
+    Then, define the callback function that is called directly after the activity
+    is done:
+
+    \quotefromfile customactivity/activityhandler.cpp
+    \skipto ActivityHandler::activityReceiver
+    \printuntil }
+
+    \note You can first check that the \c requestCode and \c resultCode are correct.
+
+    To connect C++ with QML, add an instance of the C++ class that is handling
+    the JNI logic as a QML property in the \e main.cpp file:
+
+    \quotefromfile customactivity/main.cpp
+    \skipto ActivityHandler
+    \printuntil setContextProperty
+
+    Then, add a \l Connections element to watch for messages from C++ in the
+    \e main.qml file:
+
+    \quotefromfile customactivity/main.qml
+    \skipto Connections
+    \printuntil /^\ {4}\}/
+
+    And set the \c onClicked for the \uicontrol{"Start custom Android activity"}
+    button to:
+
+    \quotefromfile services/common/main.qml
+    \skipto onClicked
+    \printline onClicked
+
+    \sa {Qt for Android}, {Qt Android Extras}
