The following article describes recommended ways to port different types of
 
Android applications to Nokia platforms, and also covers the most typical
 
special cases.
 
 
== Normal Android Java Apps ==
 
 
[[File:porting-java.png|300px]]
 
 
Since Android applications are written in Java, direct code-level reuse is
 
typically not possible when porting to Qt. Typically the application design and
 
assets can be reused in a new QML UI, and the code rewritten.
 
 
== Java Native Interface ==
 
 
A notable special case is where the Java Native Interface (JNI) is used in the
 
Android application. JNI allows the use of C/C++ shared libraries from Android
 
code.
 
 
Although this is not a recommended way to develop basic Android applications,
 
it is very useful in some specific cases — for example, with games relying on
 
existing game engines, which are often written in C/C++.
 
 
If the Android application uses these kinds of C/C++ shared libraries,
 
code-level reuse is also often possible, especially towards the Maemo platform
 
but also sometimes towards the Symbian platform.
 
 
== WebKit ==
 
 
Nowadays, in addition to developing Android applications directly in the Java language, several Android applications are also built as web applications using the WebKit approach with tools like [http://www.appcelerator.com/products/titanium-mobile-application-development/ Titanium Mobile] or by utilizing the LibWebCore in manual fashion from the Android application.
 
 
For these types of web applications the recommended porting approach is to rewrite the application with Qt Quick, especially if the intention is to develop an impressive UI. For more information on Qt Quick, see [[Porting  Mobile Applications to Qt#Qt Quick and QML Language|the section on Qt Quick in the porting introduction]].
 
 
Developers could also consider building a Qt Quick application and basing its functionality on embedded web views; for more information, see [[Fundamental use cases for porting iPhone and Android applications to Qt#Web View|the Fundamental porting use cases document]].
 
 
== User interface ==
 
 
[[File:porting-graphics-requirements.png|450px]]
 
 
Although code cannot typically be reused, the graphics and design of the
 
application can often be reused to good effect. For example, in Qt Quick,
 
scaling of the existing UI elements is very easy and may not require much
 
rework from the UI designers.
 
 
Generally, however, your application will look best and be most usable if you
 
take some time to redesign the application layout. An application layout that
 
looks great on an Android device may not be very usable on a Nokia device,
 
since the usage paradigm of user interface and available features affecting the
 
user experience are different.
 
 
For more information on UI design for Nokia devices, see
 
[http://www.developer.nokia.com/Design/ the Nokia Developer Design and User Experience Guide].
