    I think they forgot to google translate the disadvantages of JEB Decompiler

    I haven't used JEB to comment, but I've gotten a lot of mileage out of and then feed the normal Java jars it produces into and (of course) one shouldn't overlook picking your favorite tool for dealing with AndroidManifest.xml which often has fun things hiding in it
