Kindly, help please : wrong interpretation of event handler's parameter

[Sandeep Tuppad]

Hi Guys,

Hope you are doing good. Thank you very much for your efforts on dex2jar.

I have attached following files:

1) app-debug.apk -- The compiled apk

2) app.rar - The app folder of the android project zipped contains source code 

3) app-debug-dex2jar.src.zip -- The reverse engineered code generated with dex2jar+jdgui

The function attached to a button in MainActivity is:

    public void TextData(View view) {

        System.out.println("Clicked on TextData");

        String text1 = "First text information on clip"+String.valueOf(count);

        String text2 = "Second text information on clip"+String.valueOf(count);

        String desc = "testing-text"+String.valueOf(count);

        clipboard = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);

        data = ClipData.newPlainText(desc, text1);

        data.addItem(new ClipData.Item(text2));

        clipboard.setPrimaryClip(data);

        count++;

    }

However in the reverse engineered code the function is decoded as:

  public void TextData(View paramView)

  {

    System.out.println("Clicked on TextData");

    paramView = "First text information on clip" + String.valueOf(count);

    String str1 = "Second text information on clip" + String.valueOf(count);

    String str2 = "testing-text" + String.valueOf(count);

    this.clipboard = ((ClipboardManager)getSystemService("clipboard"));

    this.data = ClipData.newPlainText(str2, paramView);

    this.data.addItem(new ClipData.Item(str1));

    this.clipboard.setPrimaryClip(this.data);

    count += 1;

  }

The paramView(view in original code) is being assigned with "First text information on clip"+String.valueOf(count); incorrectly, while it's no where referenced in the function. 

I see this happening with every function which has a parameter being used as the first object being used for assigning value.

The behavior can be observed with other functions too. Kindly help.

have you tried another  decompiler, like https://bitbucket.org/mstrobel/procyon/wiki/Java%20Decompiler
