Java to Smali Code Converter

How it works:

This tool helps you convert Java code changes to Smali code by analyzing the differences between your original and modified Java files, then applying similar transformations to the Smali code.

📚 Java to Smali Conversion Patterns:

🔤 String Literals:

Java: "Hello World" Smali: const-string v0, "Hello World"

🔧 Method Declarations:

Java: public void myMethod(String param) Smali: .method public myMethod(Ljava/lang/String;)V

🏷️ Field Declarations:

Java: public static String modulePath; Smali: .field public static modulePath:Ljava/lang/String;

📞 Method Calls:

Java: Log.d("TAG", message); Smali: const-string v0, "TAG" invoke-static {v0, v1}, Landroid/util/Log;->d(Ljava/lang/String;Ljava/lang/String;)I

🏗️ Object Creation:

Java: new StringBuilder(); Smali: new-instance v1, Ljava/lang/StringBuilder; invoke-direct {v1}, Ljava/lang/StringBuilder;->()V

Original Java Code: Paste the original Java code
Original Smali Code: Paste the Smali code compiled from the original Java
New Java Code: Paste your modified Java code
Generate: Click convert to get the corresponding modified Smali code

🎯 Common Conversion Patterns:

Package names: com.example.app → Lcom/example/app;
Method signatures: (String, int) → (Ljava/lang/String;I)V
Variable registers: Java variables become Smali registers like v0, v1, p0, p1
Control flow: if-else becomes conditional jumps like if-nez, goto
Switch statements: Become sparse-switch or packed-switch with jump tables
