long time ago, in a galaxy far, far away…

• Eclipse IDE - official IDE for Android development

• ADT plugin

• Apache Ant for building projects

Reality

• ADT plugin was buggy and unstable

• frequent crashes

• agony and crying after updates

• no multi-flavour support

• slow

• Clear project -> Restart -> Crying -> Clear project -> Restart -> Praying to God -> Clear project…

…so Google said…

and so, Android studio was born!

• officially announced at Google I/0 2013 Conference

• early alpha release was published in July, 2013

• quickly got attention of Android developers

Migrating from Eclipse

2. In Android Studio, close any projects currently open. You should see the Welcome to Android Studio window.

3. Click Import Non-Android Studio project.

4. Locate the project you exported from Eclipse, expand it, select the build.gradle file and click OK.
