如何得知proguard是否成功混淆原始碼
Android由於其代碼是放在dalvik虛擬機上的代碼，所以能夠很容易的將其反編譯為我們可以識別的代碼。所以可以利用dex2jar, JD-GUI工具來查看代碼, 看proguard是否成功混淆原始碼.
方法如下:
首先先找到反組譯的apk檔，請將apk解壓, 產生一個classes.dex的檔案
下載dex2jar
https://sourceforge.net/projects/dex2jar/
執行 d2j-dex2jar.bat "classes.dex", 然後產生了classes_dex2jar.jar
下載JD-GUI
http://jd.benow.ca/
打開classes_dex2jar.jar就可觀看原始碼
如果像以下, 很多內容都變成a b c d....就是proguard成功混淆代碼了
public static com.docsearcher.index.h a;
public static File b;
public static Integer c;
public static Integer d;
public static TextApp r = (TextApp)TextApp.a();
public static int u = -1;
public static boolean v;
public static boolean w;
private com.google.android.gms.ads.h A;
private TextView B;
private com.docsearcher.index.f[] C;
private ImageButton D;
private ImageButton E;
private ImageButton F;
private ImageButton G;
this.M = paramInt;
this.f.f = 0.0F;
System.gc();
this.k = this.i.a(localObject, this.l);
this.q = (Integer.toString(this.k.curHit + 1) + "/" + Integer.toString(this.k.maxHit));
this.o.setText(this.p + ":" + this.q);
this.f.v = this.k;
this.g.b = this.k;
this.f.c = this.k.contentString;
this.f.d = ((File)localObject).toString();
this.I.b.getCurrentItem();
proguard的用法請參考
