decompiling - Android decomplie strange problems -


i have catch strange problem android decomplie.
research, decomplie android apk apktool , dex2jar, every thing seems ok, when use jd-gui open decomplied .jar file, cannot found android activity class file in it, interested saw androidmanifest.xml file has wrote activity path in it, , promise cannot found these classes file path, what's wrong it? , how can it?

--[updated]--
found not activity class file not exists, custom widget class file too, saw layout xml has used custom widget, cannot found them real file. there in way can hide class file prevent others decompile?

enter image description here enter image description here

disassembling .dex file contains java source code. file commonly classes.dex, multi dex applications can exist anywhere in classes#.dex # number >= 1.

you not find androidmanifest.xml , various layout files in .dex file. these located elsewhere (resources.arsc, androidmanifest.xml , res/) , decoded human-readable form apktool.

additionally, can't hide anything. if application runs on android, there chance can decoded. obfuscation can help, won't prevent viewing of source.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
