aachen.de Android belongs to the leading operating systems for mobile devices, e.g. smartphones or tablets. The availability of An-droid’s source code under general public license allows inter-esting developments and useful modifications of the platform for third parties, like the integration of real-time support. This paper presents an extension of Android improving its real-time capabilities, without loss of original Android func-tionality and compatibility to existing applications. In our approach we apply the RT_PREEMPT patch to the Linux ker-nel, modify essential Android components like the Dalvik virtual machine and introduce a new real-time interface for Android developers. The resulting Android system supports applications with real-time requirements, which can be im-plemented in the same way as non-real-time applications
