Android Run Time •The Android Runtime was designed specifically for Android to meet the needs of running in an embedded environment where you have limited battery, limited memory, limited CPU. •The DVM runs something called dex files, D-E-X and these are byte codes that are the results of converting at build time. Class and JAR Files.
  • 17. Android Run Time •This is in blue, meaning that it's written in the Java programming language. •The core library contains all of the collection classes, utilities, IO, all the utilities and tools that you’ve come to expected to use.
