A DEX file is an executable file saved in a format that contains compiled code written for Android, Google’s Linux-based mobile phone platform. It is technically referred to as a “Dalvik Executable,” and can be interpreted by the Dalvik virtual machine.
What is difference between Android runtime and Dalvik virtual machine?
ART and Dalvik are compatible runtimes running Dex bytecode, so apps developed for Dalvik should work when running with ART….Difference Between DVM and ART.
| DALVIK VIRTUAL MACHINE | ANDROID RUN TIME |
|---|---|
| Longer app loading time | Extremely Faster and smoother Faster and app loading time and lower processor usage |
Is Smali a bytecode?
From the official git¹, “smali/baksmali is an assembler/disassembler for the dex format used by dalvik, Android’s Java VM implementation”. The Java bytecode is compiled into Dalvik bytecode which is then executed by the Android environment; which in modern devices is Android RunTime (ART). …
How do you write Smali code?
Well the easiest way to do it would be starting from the opposite end.
- Get Android SDK and Eclipse downloaded and set up.
- Write the java code which resembles what you want to do as closely as possible for a simple non-system app.
- Build the apk in eclipse.
- Decompile and Baksmali the apk and look at the smali code.
