Android gets the size of bitmap

Recently entered the new company internship, when looking at the project code to see the previous colleague is so written code to get the size of bitmap:

return Bitmap.getrowbytes () * bitmap.getheight ();//Get size and return

It feels strange why this is calculated instead of calling Bitmap.getbytecount directly ();

After reviewing the document, it is not known that the project is minsdk=8,targetsdk=19 and therefore cannot be called directly, but written in this way. However, I still feel that this is not rigorous, because the API level 12 after the version of the new method is still used.

Here's a summary of the code to get the bitmap image size:

public int getbitmapsize (Bitmap Bitmap) {if (Build.VERSION.SDK_INT >= build.version_codes. KITKAT) {//api 19return bitmap.getallocationbytecount ();} if (Build.VERSION.SDK_INT >= build.version_codes. HONEYCOMB_MR1) {//api 12return bitmap.getbytecount ();} return Bitmap.getrowbytes () * Bitmap.getheight ();//earlier version}
