I have a picture in memory a format (output from pyplot) and I want to directly show it on the Android through Kivy, but I don't want to create a picture file. Is there any way to do this? On pyplot I am able to generate the file like object by writing it the object, but I don't know how to put it into Kivy.

Similar to the first answer but doesn't require img_pygame:
from kivy.core.image import Image as CoreImage
from kivy.uix.image import Image
import io
import qrcode # specific to my usecase, interchangeable with Pil.Image
# OR
from PIL import Image as PilImage
msg = "text"
image = Image(source="")
imgIO = io.BytesIO()
qr = qrcode.make(msg) # returns PilImage object
qr.save(imgIO, ext='png') # equivalent to Pil.Image.save()
imgIO.seek(0)
imgData = io.BytesIO(imgIO.read())
image.texture = CoreImage(imgData, ext='png').texture
image.reload()

But what if I want to play a video instead of an image?
If you want to display a binary image directly into kivy you can simply work with io module (import io) and kivy image module (kivy.uix.image)
Check this code:
from kivy.uix.image import Image, CoreImage
import io
f=open("img.jpg",'rb')
binary_data= f.read() #image opened in binary mode
data = io.BytesIO(binary_data)
img=CoreImage(data, ext="png").texture
new_img= Image()
new_img.texture= img

You could save the file into a buffer with StringIO (see this: Binary buffer in Python).
Something like:
from StringIO import StringIO
buff = StringIO()
plt.savefig(buff)
buff.seek(0)
from kivy.core.image.img_pygame import ImageLoaderPygame
imgdata = ImageLoaderPygame(buff)._data

How do I get the Image object to have the picture?
