title: How to extract code of .apk file which is not working?
body: <p>Actually I was trying to extract code of a .apk file called cloudfilz.apk and wanted to manipulate in its source code so I followed the steps given below:-</p>
  <p>make a new folder and put .apk file (which you want to decode) now rename this .apk file with extension .zip (eg: rename from filename.apk to filename.apk.zip) and save it..now you get classes.dex files etc...at this stage you are able to see drawable but not XML and java file...so continue...</p>
  <p>Step 2:</p>
  <p>now extract this zip apk file in the same folder(in this eg or case NEW FOLDER). now download dex2jar from this link <a href="http://code.google.com/p/dex2jar/" rel="nofollow noreferrer">http://code.google.com/p/dex2jar/</a> and extract it to the same folder (in this case NEW FOLDER).....now open command prompt and reach to that folder (in this case NEW FOLDER)....after reaching write &quot;dex2jar classes.dex&quot; and press enter.....now you get classes.dex.dex2jar file in the same folder......</p>
  <p>=&gt;Question:-I was successful to achieve step 1 but in step2 when I am executing dex2jar classes.dex I am getting an error on command prompt <code>java.lang.UnsupportedClassVersionError</code> ,I know this is due to incompatibility between my installed JDK version and classes.dex JDK version number so stuck here and don't have way out...</p>
