Initialize local git repository and create origin master

Go to the root directory you want for this repo and execute following commands

 local$ git init

Create the repo on your server

 local$ ssh server
 server$ cd /path/to/git/root
 server$ mkdir newrepo.git && cd newrepo.git
 server$ git --bare init
 server$ exit

Add the origin master to your local git

 local$ git remote add origin ssh://server/path/to/repo.git
 local$ git push origin master

clone a git for local changes that can be pushed again to origin master

SSH login with key

Create ssh key on local computer

If you haven't already created a key to use, you can generate a RSA key with the following command

 ssh-keygen -t rsa

Add the key to the destination server

All you have to do is to copy the public part of your key onto the server's .ssh directory

 ssh-copy-id -i ~/.ssh/

Android Splashscreen

Howto implement a splashscreen in android

Frozen Egg
Frozen Egg - Market link
While working on the easter theme for Frozen Bubble (Frozen Egg => market://search?q=pname:ch.racic.frozenegg) I searched for a way to show a splashscreen while the app was loading.

The first implementation of a splash screen was to start a small activity that shows a splash image for a certain time period and the starts the main activity but this still shows the black screen while loading the main activity.
I remembered that toast messages can be customized and can contain images, thats my second implementation that I want to show to you.
Feel free to comment if you have better ways or ideas how to implement a splashscreen better.
