[Vietnam Mobile Day 2013] - Memory management for android applications

The document discusses memory management for Android apps. It covers heap size limits which have increased over time from 16MB to 64MB on newer devices. It also discusses garbage collection, noting that earlier versions had stop-the-world pauses over 100ms while newer versions since Gingerbread are concurrent with pauses under 5ms. Bitmap management is also covered, explaining how bitmaps were freed via recycle() before Android 2.3, resulting in full garbage collections, whereas newer versions free bitmaps synchronously during concurrent garbage collection.
