[android-developers] Slow motion video

[TheBear]

I am able to play back video using the mediaplayer with the standard
video control buttons.

My question is how can I use a slider /progress bar to act as a play
back speed.
which function would I have to override and how.
basically

while not end of movie
play next frame
sleep (value of progress bar   (0 - 100) * 4000);

this way when the slider/progress bar is at 0 sleep is 0; thus there
is NO delay in playback

when the slider is at 100 then sleep is 40,000, thus there is a 40
second delay between frames causing the video to slow.

As you can see I have a concept but I am not sure of the routines, I
found reference to play a frame
 but could not find any examples and it would appear that it is now
depreciated.

thanks in advance

[android-developers] Re: Camera App

[TheBear]

Okay thanks for that, but what I'm trying to do is have a single
button in my app, and then let the user decide if they want to photo
or video once they are in the  camera app.  Just as if they selected
the camera app from the home screen.

How can I just call the camera app from within mine and have it behave
as if they clicked it from the home screen ?

thanks again

[android-developers] Mouse Pointer

[TheBear]

Anyone know how to create a mouse pointer  for the finger ??

I have a framelayout  which displays an ImageView  This must be the
background image
Then on top  I am trying to draw lines
I'm trying to have a mouse pointer  (looks more like a target sites)
so that you can fix the start of the line
then  using the same fix the end of the line and finally draw a line
between the two points

I'm using the onTouch  and triggering with ACTON_DOWN etc..

When I move the pointer it either leaves a ghost trail behind,  or  if
using XferMode   leaves a black square ?

any help would be greatly appreciated

thanks in advance
