1. Welcome!

2. All you need to start writing your own Android
applications is
a copy of the Android SDK and
the Java development kit.

3. You need java platform to build Android
App with any IDE.
So if you don't have one:
Java JRE or JDK:
http://docs.oracle.com/javase/7/docs/webnotes/install/i
(sudo apt-get install openjdk-7-jre for Linux)

4. Problems?
Java JRE or JDK: check this out
http://docs.oracle.com/javase/7/docs/webnotes/ins
for Linux try something like:
tar xzvf ~/Downloads/jdk-7u<your version>-linux-x64.tar.gz
sudo mv jdk1.7.0_21/ /usr/lib/jvm/
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_<your
version>/bin/java 1
sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.7.0_<your
version>/bin/javac 1
sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.7.0_<your
version>/bin/javaws 1
sudo update-alternatives --config java
sudo update-alternatives --config javaws

5. IDEs: Android Studio or Eclipse
(Android Development Tools plugin)
Eclipse – less bugs, particularly popular for Java devel-
opment.
Installing Eclipse+ADT a bit more challenging.
Android Studio – a lot bugs, very easy to set up, better
app design tools, worse geo position tracking on virtual
device.

6. Eclipse ADT (for guys new to Eclipse):

Android Studio:
Eclipse (and want to follow few steps of upgrading it on
slides below):
http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developer
would recommend Classic:
