Is it possible to view Dalvik bytecode for my app in Android Studio? If so, how?
Update:
My app is written in Java using Android Studio and I want to see my Java classes byte code, which is also known as Dalvik bytecode, (not the source code) inside Android Studio.

Dalvik bytecode format is still used as a distribution format, but no longer at runtime in newer Android versions. Android itself is a Linux system with Dalvik sitting on top of it. DVM takes android app, turns them from java code into bytecode that the Linux system can run.
Starting with version 0.2.10, Android Studio includes a built in viewer for viewing Dalvik VM traces. This is intended as a replacement for traceview tool that is part of DDMS/Monitor and ADT.
In ART instead of interpreting code at runtime code was compiled before running the app and when the app was running, machine code was already prepared. This approach hugely improved runtime performance since running native, machine code is even 20 times faster than just in time compilation. ART in Android L used a lot more RAM than Dalvik.
If you already have a trace file that was generated programmatically on the device, then pull that file from the device to your host and then open it in Android Studio (File | Open...) Click on the "Start Method Tracing" icon as shown in screenshot 1 below.
It is now possible to inspect bytecode directly from Android Studio (Since version 3.0 Canary 1). Go to Build-> Analyze APK..., select your APK file. Navigate too class you are interested in, right click on it and select "Show Bytecode". You can also use your mapping file if your APK file is generated with Proguard.
