<html>Bytecode Viewer (BCV) was designed to be extremely user and beginner friendly, because of this almost everything
|
|
is accessible through an interface, settings, tools, etc. This means if you give BCV a try you should get the gist of it
|
|
can do, however for those who don't want to run BCV until they're convinced they should use it, below is a complete list
|
|
of features BCV has, and what they do.
|
|
|
|
<h2>Command Line Interface (CLI):</h2>
|
|
<ul>
|
|
<li> -help Displays the help menu</li>
|
|
<li> -list Displays the available decompilers</li>
|
|
<li> -decompiler [decompiler] Selects the decompiler, procyon by default</li>
|
|
<li> -i [input file] Selects the input file (Jar, Class, APK, ZIP, DEX all work automatically)</li>
|
|
<li> -o [output file] Selects the output file (Java or Java-Bytecode)</li>
|
|
<li> -t [target classname] Must either be the fully qualified classname or "all" to decompile all as zip</li>
|
|
<li> -nowait Doesn't wait for the user to read the CLI messages</li>
|
|
</ul>
|
|
|
|
<h2>File:</h2>
|
|
<ul>
|
|
<li>Add (Ctrl + O) - If you add a jar/zip BCV will unzip it, if you add an APK or DEX file, BCV will run dex2jar
|
|
then run the jar input process.
|
|
</li>
|
|
<li>New Workspace (Ctrl + N) - It clears the opened jars/resources.</li>
|
|
<li>Run (Ctrl + R) - Runs the classfiles you've loaded into BCV in a secure sandboxed JVM instance that you can
|
|
fully debug.
|
|
</li>
|
|
<li>Compile (Ctrl + T) - Tries to compile all of the editable panes you've selected, if it's Java it'll compile with
|
|
Ranino. Krakatau and *Smali use their own assemblers.
|
|
</li>
|
|
<li>Save As Jar - Export the class files and loaded resources as a runnable Jar file.</li>
|
|
<li>Save As DEX - Run jar2dex and export the Classfiles as DEX.</li>

<li>Save Files As - Save all the Classfiles and resources as a zip.</li>
|
|
<li>Save Java File As - Save the currently opened decompiled Classfile.</li>
|
|
<li>Save Java Files As - Save all of the decompiled Classfiles as a zip.</li>
|

|
|
resources.

<h2>Notes:</h2>
|
|
<ul>
|
|
<li>If BCV fails to boot simply append -clean as an argument to clean the lib directory.</li>
|
|
<li>Relax and take notes, while I take tokes of the marijuana smoke.</li>
|
|
<li>BCV was created out of love for Java Reverse engineering.</li>
