#Android meetup
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
