Ngamanye amaxesha ufuna ukubona, yaye yintoni uhlobo ngokuzalisa inkqubo ethile? Emva koko kufuneka asebenzise Ebuyiselwayo-zobunjineli. Yintoni na? Zisebenza njani? Njani le nkqubo? Konke oku uya kufunda kweli nqaku.
Yintoni a iinkqubo reverse-zobunjineli?
Ngoko wabiza analysis yesicelo inkqubo ukuze balwazi ukuba lusebenza njani, ukuze kwixesha elizayo ukuyenza le nkqubo ngokwenza utshintsho oluyimfuneko. kusetyenziswa Ngokuqhelekileyo le debugger njongo kunye assembler. Kuxhomekeka umgangatho software esetyenzisiweyo iya kwahluka yaye isiphumo isixa sexesha ekufuneka lichithwe kuwo ukuzisa ngendlela eqhelekileyo. Cacisa reverse-zobunjineli kwabasaqalayo umzekelo ilungileyo. Njengoko yawo enze isicelo esibhaliweyo sokuba Android. Ngoku makhe kuba ukufumanisa oko nendlela.
Ukusebenza kunye Android-izicelo
Okokuqala kufuneka ukucacisa ezinye iindawo. Isicelo isebenzisa bytecode kunye LogCat. Oku nabalingani zendawo ngaphambili ekhankanywe kubengqukuva kunye assembler. Kuyimfuneko ukuba ukuqonda isakhiwo kwezicelo ngokwabo. Ngenxa yoko, inkqubo nganye yifayile kunye ulwandiso Download. Wapakisha zip'om.

Kodwa ngaba unako ukufumana opcodes dalvik - iseti eyodwa imiyalelo asetyenziswa kumatshini onesiqhamo. Kuba isifaniso sinokuthi kulo ibandla isikhukhula. Classes.dex kwakhona inokujikwa ibe ifayile embizeni. Nokuba kwimeko enjalo, ungafumana i java-ikhowudi emva decompilation, nto leyo eya kuba ngaphezulu okanye efundeka ngaphantsi. Leyo kwindledlana sihambe.
decompilation
Le nkqubo iza kwenziwa ngokusebenzisa inkqubo APK wesitali. Phambi kokuba uqale, qinisekisa ukuba kukho umqhubi ezichanekileyo devaysa nesebenza imo USB-USB. Ekuqaleni, siya kufuneka ukuhambisa ifayile oya kuthi silandelwe ibe umyalelo apk_manager \ indawo-Download-apha-for-modding. Emva koko kufuneka usebenzise Script.bat. Ukuba akukho ngxaki, ngoko ukuqala i console, nto leyo eya kuba magama eluhlaza. Khetha inombolo indawo elithoba - "kuyekwe". Xa le nkqubo iqale, kuyimfuneko ukuba avale console. Emva koko, inzala vula Download-ifayile usebenzisa archiver kunye kucatshulwe kuyo classes.dex, ukuba lumakishwe dex2jar program. Kuba nathi isiphumo efunekayo kuyimfuneko ukuba into kunye ulwandiso .bat. Uya kubona ifayile, neliya kuphela ngo .jar. Ukuza kuthi ga ngoku, i-window ayivaleki.
thina uhlaziye idatha
Ukuze ufumane ulwazi malunga nesicelo, kufuneka uvule ibonakale. Ngokutsho kuyo, thina unokumisela ukuba lisebenza umsebenzi omkhulu. Yaba yena lowo ngoku osondeza kubaluleke kakhulu kuthi. Kunqweneleka ukuba bajonge ezantsi program. Ukuba Undoqo ulwazi malunga umphathi mvume, kunzima kakhulu ukwenza zobunjineli umva. Ukuba uguqulela jd-gui nokwandisa umthi, sinako ukubona namespaces eziliqela. Ukucinga ukuba bobathathu. Kulo sokuqala iifayile ezinxulumene izibhengezo. Le yesibini iya kuba iiklasi ngumphathi mvume. Kulo wesithathu, thina iinkcukacha eziyimfuneko. Yinto xa thina sihambe. Kuza kufuneka ukuba ukufumana nokususa isitshixo, kwaye ke eminye imigca ezikhangela nokuba onelayisensi version ukusebenza. Zonke ezi kufuneka zicocwe. Kwandula Umphathi wethu APK ifuna indawo apho kwindawo ekhankanyiweyo bytecode. Ngoku makhe senze kuphambuko encinane gqabaza iqela, leyo ezinokuba kunokubangela iingxaki. Emva koko, siya kufuneka nje ukuba iqulunqe inkqubo.
Yakha izicelo
Oku kuya kusinceda zonke Manager efanayo APK. Kulo console, abangancedekanga itshixiwe thina, khetha umba №14. trick elandelayo. Ukuba isicelo kunokuba nzima, xa uqala, nokuba ngokupheleleyo okanye ukuphelelwa ukusebenza kwayo. Musa Ungakhathazeki, oko kuthetha ukuba kuphela gabhu apho kwenye indawo ukuya.

Njengoko ubona, i zobunjineli umva asinto ishishini lula, yaye oko kufuna ukuba ivenkile enkulu ulwazi. Nokuba yonke into isebenze ngaphandle naziphi na iingxaki, kuya kuba yimfuneko ukuba ukuvavanya ukusebenza izicelo. Oko kukuthi, i-reverse-engineering umsebenzi ngakumbi ethatha ixesha elide. Siyaqhubeka sisebenze de zonke iingxaki ezithe zafunyaniswa.
ukuphepha
Kuthekani ukuba sifuna ukukhuselwa Zonke Android-sicelo evela zobunjineli umva?

Ngoko ke, uthathe ithuba yinto ezitho developer oluthixo izixhobo umgangatho kwendalo kunye nophuhliso.
isiphelo
Asinako ukuba abhalwe-zobunjineli angamelwa njengento zazidla ngokuba elungileyo okanye embi. Kakade ke, ukususela kwinqanaba umbono developers, abaye udale isicelo, oko akukho isiganeko tsakela. Kodwa kwelinye icala, kwiimeko ezininzi abanamava badwelisi benkqubo ababhala iifayile oluyimfuneko lixesha ibiza ngaphantsi ukusetyenziswa izixhobo ezinjalo. Nangona ngababhekisi abo basandula kuqalisa reverse-zobunjineli zingenza eyakho i inkonzo elungileyo ukuba akukho ingcamango ukuphumeza njani into, nokuba ngumzekelo, hayi kakhulu inkcazelo ecacileyo mibuthoinganceda ekufikeleleni kule njongo.
