[SOLVED] Dynamically adding files to the cache in Android

[trajano]

How do you dynamically add files to the cache/ folder in Android? On the PC I can do the renpy.loader.get_path to get the real path but this fails on Android

Code: Select all

        def queue_blips(who, what, cps):
            """
            Queue the blips.  This creates a blip every other character and resets the blip when a comma or space is detected.
            If the CPS is higher frequency than the blip length, it switches to Wendy Oldbag mode where it just beeps as fast
            as it can.
            """

            computed_blip_file = "cache/%d.wav" % ( hash( (who, what, cps) ) )
            computed_blip_path = os.path.normpath(renpy.loader.get_path(computed_blip_file)).replace("\\", "/")
            if os.path.isfile(computed_blip_path):
                renpy.sound.play(computed_blip_file)
                return

            tokens = textsupport.tokenize(unicode(what))
            odd = False

            blipout = wave.open(computed_blip_path, "wb")
            blipout.setframerate(blip_framerate)
            blipout.setsampwidth(blip_sample_width)
            blipout.setnchannels(blip_channels)

            cps_stack = []
            # initial character gap

            def silence(seconds):
                silence_byte_length = seconds *  blip_framerate * 2
                return audioop.tostereo(b'\0' * int(silence_byte_length), 1, 1, 1)

            def blip(seconds):
                silence_byte_length = ((seconds - blip_length) *  blip_framerate ) * 2

You *might* get away with using the save directory:

Code: Select all

define config.save_directory = "sub_folder_name"

# Note: That is often set in options.rpy based on the project name (near line 145)

#
# then, in the code that wants to use that directory, read the value with :
config.savedir # <-- full absolute path depending on platform (do Not use this to set the value)

I was able to write to the save directory, but Ren'py won't read the files from it in Android for media playback. I found a workaround using io.BytesIO the example I have is in my blip library viewtopic.php?f=51&t=55866
