What is the meaning of hexadecimal number that see in strings of MAT report?

Question

I used eclipse Memory Analysis Tool ( MAT ) to take a heap dump profile for a process on an android device. along with all objects I see a cryptic looking hexadecimal number

example:

android.graphics.Bitmap @ 0x428e5c90

android.graphics.Bitmap @ 0x428f5888

android.graphics.Bitmap @ 0x42717950

android.graphics.Bitmap @ 0x426fed10

Can anyone help me find out what these numbers are and also can i use them in tracking more specifically the items they are associated to?

Answer 1

Its hash code. You can find that specific bitmap using Gimp

Steps to get bitmap

1] click on bitmap you will get its detail information in right-side pane.

2] click on mBuffer and right click on it, you will get options in that select copy --> save value to file save value with ".data" extension.

3] Now open that file on Gimp.

4] choose "Image type" as "RGB Alpha" set height and width as mentioned in mWidth and mHeight fields in MAT.

Answer 2

That's HachCode of object, one of several things used for testing for equality, because Hashed values are more or less unique. For more information, refer to source code of Object
