i decompiled an Android .apk file using dex2jar, grabbed the java source files using jd-gui "File Save All Sources" and got a .zip file and the java files within. I did exactly the steps in this "guide": http://a4apphack.com/security/sec-code/extract-android-apk-from-market-and-decompile-it-to-java-source. Then i made some changes in a couple of the java files, now i am wondering how i can recreate an apk file. Decompiling with apktool, backsmali and smali tools work with .smali files, but now i have .java files...
