 ==== How to get Eclipse and Android work in Ubuntu? ==== ==== How to get Eclipse and Android work in Ubuntu? ====
 +For eclipse you need to use sun java packages (gcc gjc java is installed by default but it does not seem to work well)
 +  * https://help.ubuntu.com/community/Java
 +  * get JDK (SDK) package as well

 +==== Does anybody know how to launch another application, e.g. "YouTube" from your own program? ====
 +I know how to launch web-browser, if smb needs I can explain. Also I've installed some applications to the emulator, except YouTube :(. By the way we know how to send data from one activity to another and few other features, that could be useful just ask, may be we've faced with it! Vadim.
 +
 +A: A generic answer to this is that you need to know the intent filter of the started activity/application. When you know the intent filter you can always create intent that is going to match to the filter. Then, it is simply just a call on Context.startActivity(intent). All the "standard" platform applications and their AndroidManifest.xml files are in the public repository.
