simple understandigs.

The german Wikipedia-Page "Android" says:
Um eigene Programme für Android zu entwickeln, benötigt man ein
aktuelles Java-SDK und zusätzlich das Android-SDK. Zuerst wird der in
Java geschriebene Quelltext mit einem normalen Java-Compiler übersetzt
und dann von einem Cross-Assembler für die Dalvik-VM angepasst. Aus
diesem Grund können Programme prinzipiell mit jeder
Java-Entwicklungsumgebung erstellt werden.
(To develop own programs for Android you need a recent Java-SDK and
additionally the Android-SDK. First the Java source code is translated
with a standard Java compiler and then adapted with a cross-assembler
for the Dalvik-VM. Therefore programs can be written in principle with
every Java Development Toolkit).
(I took the German Wikipedia page because this subject is covered
better than on the english page).
On Pro-Linux.de (Aug. 12, 2011) I found: A group of developers found a
way to run normal Java applications on Apple-iPads and Android devices
(http://www.pro-linux.de/news/1/17375/java-se-fuer-ios-und-android.html).
But no details seem to be known yet.
