How Applications Are Run on Android ?
How applications are run on Android ? Jean-Loup Bogalho & Jérémy Lefaure [email protected] [email protected] Table of contents 1. Dalvik and ART 2. Executable files 3. Memory management 4. Compilation What is Dalvik ? ● Android’s Virtual Machine ● Designed to run on embedded systems ● Register-based (lower memory consumption) ● Run Dalvik Executable (.dex) files What is ART ? ● Android RunTime ● Dalvik’s successor ● ART Is Not a JVM ● Huge performance gain thanks to ahead-of-time (AOT) compilation ● Available in Android 4.4 What is ART ? Executable files Dalvik: .dex files ● Not the same bytecode as classical Java bytecode ● .class files are converted in .dex files at build time ● Optimized for minimal memory footprint Dalvik: .dex files Dalvik: application installation ● Verification: ○ bytecode check (illegal instructions, valid indices,...) ○ checksum on files ● Optimization: ○ method inlining ○ byte swapping and padding ○ static linking ART: OAT file ● Generated during installation (dex2oat) ● ELF format ● Classes metadata Memory management Zygote ● Daemon started at boot time ● Loads and initializes core libraries ● Forks to create new Dalvik instance ● Startup time of new VM is reduced ● Memory layouts are shared across processes Dalvik: memory management ● Memory is garbage collected ● Automatic management avoids programming errors ● Objects are not freed as soon as they become unused Dalvik: memory allocation ● Allocation profiling: ○ allocation count (succeeded or failed) ○ total allocated size (succeeded or failed) ● malloc -
