Abstract

Ovaj rad se bavi problematikom analize APK datoteka i dekompajliranja njihovog koda niže razine u izvorni kod. Na početku su opisane komponente Android aplikacija, njihov proces izgradnje i sigurnosni model. Zatim je objašnjena struktura APK datoteka i smali kod koji je ponekad potreban kako bi se razumio izvoran kod aplikacije. Osim toga navedeni su neki alati koji olakšavaju analizu APK datoteka. Za dekompajliranje prevedenog su korištena tri dekompajlera: Jadx, Procyon i Fernflower. U posebnom poglavlju je objašnjeno kako ih koristiti, koje su njihove mogućnosti i kako ih koristiti programski. Osim dekompajlera objašnjen je i alat dex2jar koji je korišten za transformaciju DEX datoteka u JAR datoteke. Zatim je opisano kako razviti vlastiti dodatak za Android Studio razvojno okruženje u IntelliJ IDEA alatu. Objašnjena je IntelliJ platforma, komponente dodataka i kako podesiti IntelliJ IDEA alat za razvoj. Na kraju je prikazan razvijeni dodatak za Android Studio koji integrira navedene dekompajlere i nudi dodatne mogućnosti.

Abstract (english)

This thesis studies the analysis of APK file and decompilation of its bytecode into source code. At the beginning the components of Android applications, their build process and security model are described. Then the structure of APK file and smali code which is some times needed in order to understand the source code are described. Additionally some tools which make analysis of APK file easier are mentioned. For decompilation of compiled code three decompiler were used: Jadx, Procyon and FernFlower. In separate chapter it is described how to use them, which are their features and how to use them programmatically. Besides decompilers the tool dex2jar for transforming DEX files to JAR files is described. Then it is described how to develop custom plugin for Android Studio development environment in the IntelliJ IDEA tool. IntelliJ platform, components of the plugin and how to setup the IntelliJ IDEA tool for plugin development are described. At the end, the developed plugin which integrates mentioned decompilers and provides additional features is shown.
