Different app names for different build flavors?

Question

I have 2 build flavors, say, flavor1 and flavor2.

I would like my application to be named, say, \"AppFlavor1\" when I build for flavor1 an

Answer 1

How do I make string/app_name different per flavor though?

I wanted to write an update, but realized that it is bigger than the original answer saying that I use a Python script that patches the source.

The Python script has a parameter, a directory name. That directory contains per-flavor assets, resources like launcher icons, and the file properties.txt with a Python dictionary.

{ 'someBoolean' : True
, 'someParam' : 'none'
, 'appTitle' : '@string/x_app_name_xyz'
}

The Python script loads the dictionary from that file and replaces the value between and by the value of properties['appTitle'].

The below code is provided on the as-is/as-was basis etc.

for strings_xml in glob.glob("res/values*/strings.xml"):
    fileReplace(strings_xml,'',properties['appTitle'],'',oldtextpattern=r"[a-zA-Z0-9_/@\- ]+")

to read properties from one or more such file:

with open(filename1) as f:
    properties = eval(f.read())
with open(filename2) as f:
    properties.update(eval(f.read()))

and the fileReplace function is:

really = True
#False for debugging

# In the file 'fname',
# find the text matching "before oldtext after" (all occurrences) and
# replace 'oldtext' with 'newtext' (all occurrences).
# If 'mandatory' is true, raise an exception if no replacements were made.
def fileReplace(fname,before,newtext,after,oldtextpattern=r"[\w.]+",mandatory=True):
    with open(fname, 'r+') as f:
        read_data = f.read()
        pattern = r"("+re.escape(before)+r")"+oldtextpattern+"("+re.escape(after)+r")"
        replacement = r"\g<1>"+newtext+r"\g<2>"
        new_data,replacements_made = re.subn(pattern,replacement,read_data,flags=re.MULTILINE)
        if replacements_made and really:
            f.seek(0)
            f.truncate()
            f.write(new_data)
            if verbose:
                print "patching ",fname," (",replacements_made," occurrence" + ("s" if 1!=replacements_made else ""),")",newtext,("-- no changes" if new_data==read_data else "-- ***CHANGED***")
        elif replacements_made:
            print fname,":"
            print new_data
        elif mandatory:
            raise Exception("cannot patch the file: "+fname+" with ["+newtext+"] instead of '"+before+"{"+oldtextpattern+"}"+after+"'")
