if i add the gridlayout directly to the scrollview instead of adding it to the relative layout the scroll works

multiple kv

	def build(self):

	l= Builder.load_file('newui.kv')

	carousel.add_widget(l)
	carousel.add_widget(m)
	self.m = m
	self.l = l
	self.rootlayout = rootlayout
	self.carousel = carousel

this works on linux but not android.

	def change_image(instance, photo):
	"""open selected image, resize and blit into texture"""
	global currentTexture
	##try:
	img = PILImage.open(instance.selection[0])
	##print img
	currentTexture = Texture.create(size= (180,240))
	img2 = img.resize((180,240), PILImage.BICUBIC)
	buf = img2.tostring()
	currentTexture.blit_buffer(buf, colorfmt='rgb', bufferfmt='ubyte')

blit_buffer problem

	def change_image(instance, photo, image_slider):
	"""open selected image, resize and blit into texture"""
	global currentTexture
	try:
	img = PILImage.open(instance.selection[0])
	except: pass
	img = img.resize((180,240), PILImage.BICUBIC)
	buf = img.tostring()
	with open('buffer.txt', 'w') as f:
	f.write(buf)

in this case: self.cb = Callback(self.setup_gl_context) There are 3 instances of Callback in memory and they all reference a list that keeps growing whenever the scene is updated

	def setup_gl_context(self, *args):
	#clear_buffer
	glEnable(GL_DEPTH_TEST)
	self.fbo.clear_buffer()

using Color() in a frame buffer object

	#this draws a magenta ellipse:

	c = Ellipse(size = (200,279), pos = (220,118))

	with self.fbo:
	Color(1,0,1,1)
	c
	glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)
	Rectangle(size = (640,480), texture = self.tex.texture)

why does the frame rate slow down?

	def new_color(self, *args):
	with self.fbo:
	Color(self.mood[0], self.mood[1],self.mood[2],self.mood[3])
	Ellipse(size = (205,279), pos = (224,115))
	glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)
	Rectangle(size = (640,480), texture = self.tex.texture)
