ERROR BACKSMALI A DEX FILE
Closed this issue · 1 comments
i used this command : java -jar baksmali-2.5.2.jar d classes.dex
i get this output :
Lcom/ano/gshell/AnoApplication;-><clinit>()V: Invalid debug offset
Lcom/ano/gshell/AnoApplication;-><init>()V: Invalid debug offset
Lcom/ano/gshell/AnoApplication;->dec(Ljava/lang/String;)Ljava/lang/String;: Invalid debug offset
Lcom/ano/gshell/AnoApplication;->dec(Ljava/lang/String;)Ljava/lang/String;: Invalid debug offset
Lcom/ano/gshell/AnoApplication;->attachBaseContext(Landroid/content/Context;)V: Invalid debug offset
Lcom/ano/gshell/AnoApplication;->attachBaseContext(Landroid/content/Context;)V: Invalid debug offset
the file decompiled but when i compile the file again and replace it inside the app root folder (replace with original smali.dex)
and build with apktool and resign the installed but then the app exit
and gives this logcat :

the application runs without error when compile with original classes.dex .
but exit with the one that decompiled and recompiled with backsmali.
Sounds like some form of copy/modification protection.
