smali java

gistfile1.txt

      If you need to know the value of a string - e.g. a parameter - 
      you can use Log.d(String tag, String message) to log it to the system log.
 
 const-string/jumbo v0, "YourTag"
 invoke-static {v0, p1}, Landroid/util/Log;->d(Ljava/lang/String;Ljava/lang/String;)I
 
 
 
      If you are having trouble navigating the smali code and understand the flow of an app 
      you can use the following smali code. It will call Thread.dumpStack() which logs the current thread's call stack.
 
 invoke-static {}, Ljava/lang/Thread;->dumpStack()V
