It's easy

Get these tools:

1) dex2jar to translate dex files to jar files

2) jd-gui to view the java files in the jar

The source code is quite readable as dex2jar makes some optimizations.

Procedure:

And here's the procedure on how to decompile:

Step 1:

Convert classes.dex in test_apk-debug.apk to test_apk-debug_dex2jar.jar

d2j-dex2jar.sh -f -o output_jar.jar apk_to_decompile.apk

Note: In the Windows machines all the .sh scripts are replaced by .bat scripts

dex2jar documentation

Step 2:

Open the jar in JD-GUI
