Droidcon+ODEX file disassembly

First, the advertisement. I will make a longer presentation at Droidcon London 2009 about Dalvik bytecode in general, using Dedexer examples. This will be a longer version of my previous, short presentation (also in podcast). If central London is convenient for you, please, come. Otherwise I will share the presentation after the event.

To celebrate the event, I finished the symbolic ODEX disassembly feature in Dedexer (look for version 1.8). This means that instead of ugly offsets, Dedexer now correctly decompiles the method and field names for execute-inline, iget/iput-quick and nvoke-virtual-quick instruction families if the dependency files are available. So instead of this:

.line 3041
invoke-virtual-quick {v5},vtable #0x2c
move-result-object v2
.line 3042
iget-object-quick v3,v5,[obj+0x28]
invoke-virtual-quick {v3},vtable #0xe
move-result-object v0
.line 3043
execute-inline {v2},inline #0x4
move-result v1

You will get this:

.line 3041
invoke-virtual-quick {v5},android/app/Activity/android/app/Activity/getPackageName ; getPackageName()Ljava/lang/String; , vtable #0x2c
move-result-object v2
.line 3042
iget-object-quick v3,v5,mComponent Landroid/content/ComponentName; ;[obj+0x28]
invoke-virtual-quick {v3},android/content/ComponentName/android/content/ComponentName/getClassName ; getClassName()Ljava/lang/String; , vtable #0xe
move-result-object v0
.line 3043
execute-inline {v2},Ljava/lang/String/length ; length()I , inline #0x4
move-result v1


Much better, isn't it? See you at Droidcon and I will explain how to interpret the code fragment above.
