# Interface: com.pnfsoftware.jeb.core.units.code.android.IDexUnit - Super interfaces: `com.pnfsoftware.jeb.core.units.code.ICodeUnit` Interface for units representing Android Dalvik bytecode containers, aka Dex files. The Dex unit interface is a virtual view of the Dex bytecode contained an Android application \(APK\). Dex units use Java\-style internal addresses to identify items: \- package: `Lcom/abc/` \- type: `Lcom/abc/Foo;` \- method: `Lcom/abc/Foo;->bar(I[JLjava/Lang/String;)V` \- field: `Lcom/abc/Foo;->flag1:Z` More information here. Note that in the case of multi\-Dex APKs, the Dex unit represents a virtual, unified view of the separate Dex files contained in the APK. If required, the individual information about those Dex files can be retrieved via [IDexFile](com.pnfsoftware.jeb.core.units.code.android.IDexFile.md). Like many units, Dex unit objects emit [J#UnitChange](J#UnitChange) when the unit contents is being changed. IDexUnit set up event objects such that [JebEvent#getData()](JebEvent#getData()) will return a [UnitChangeEventData](com.pnfsoftware.jeb.core.units.UnitChangeEventData.md) with fields reasonably populated. How use the JEB API to interact with those objects? \- Writing JEB client scripts in Python is a great way to ease into the JEB API. \- Visit this public GitHub repository for sample code \- In the JEB client, use F2 to bring up the script manager, and try out some sample scripts Below is a sample client script that shows how to retrieve a project, find the main dex unit, enumerate dex methods, check the bytecode and search for specific instructions.
