# dextk
Android dex file parser in Go
### Features
- String, classes and code parsing
- Low memory usage
- Mmap support
- Designed to support stream processing (No requirement to load entire dex file into memory)
### Example
```bash
go run ./cmd/example
```
```go
package main
import (
"fmt"
"log"
"github.com/csnewman/dextk"
"golang.org/x/exp/mmap"
)
func main() {
f, err := mmap.Open("classes.dex")
if err != nil {
log.Panicln(err)
}
defer f.Close()
r, err := dextk.Read(f)
if err != nil {
log.Panicln(err)
}
ci := r.ClassIter()
for ci.HasNext() {
node, err := ci.Next()
if err != nil {
log.Panicln(err)
}
for _, method := range node.DirectMethods {
fmt.Println(node.Name, ": ", method.Name)
processMeth(r, method)
}
for _, method := range node.VirtualMethods {
fmt.Println(node.Name, ": ", method.Name)
processMeth(r, method)
}
}
}
func processMeth(r *dextk.Reader, m dextk.MethodNode) {
if m.CodeOff == 0 {
return
}
c, err := r.ReadCodeAndParse(m.CodeOff)
if err != nil {
log.Panic(err)
}
for _, o := range c.Ops {
fmt.Println(" ", o)
}
}
```
Output:
```
