Mobile Celestia for Android

[mario.schinder]

The main problem to migrate it to Android is, most of the software is written in C++, and there is a not easy and direct way to translate software from C++ to Java... so I guess that the amount of work is tremendous, maybe it is better to write it from scratch and maybe that code could be used to replace the current C++ one... otherwise... it does not look easy job to be done

maybe it is better to write it from scratch

well only if the original developers would do that.

Android apps can call C++ codes with JNI, and this is how this app uses the existing code, it uses a Java shim to call into the C++ code. The difficult part was getting it to work and render the first scenes, once it is done, it is just like any other mobile app, how to build a good UI and interaction model, etc.

Since it is already out there, you are more than welcome to try it from the play market.

really?! good to know I will try that, and actually I did not know that was a wrapper that allows Java to interact with C++ software... thanks!
