dex2jar is a set of Java-based command-line tools for working with Android .dex and Java .class files. It converts Dalvik executables (e.g., from APKs) into Java class files (JARs) and can disassemble/assemble dex to/from smali.

Use cases

• convert an apk's dex to a jar for decompilation
• disassemble dex files to smali
• reassemble smali back into a dex file
• analyze android app bytecode
• read and write dex files programmatically
• decrypt obfuscated strings in android apps

When to choose

• you need to convert Android dex bytecode to Java class files for static analysis
• you want to disassemble or reassemble dex via smali syntax
• you're doing Android reverse engineering or malware analysis

When to avoid

• you need a full decompiler producing readable Java source (pair it with a decompiler like CFR or Fernflower)
• you need to build or run Android apps rather than analyze them
• you need active feature development - the project is largely in maintenance mode
