a 1024x1024 bitmap will be (IIRC) 4MB. Creating a few will likely
cause you to run out of memory. Use Bitmap.recycle to free up the
resources that a bitmap you no longer need is using

I'm making a custom listview and I would like to use the standard
textview shown in the tutorial to display the text items (defined in
android.R.layout.simple_list_item_1). How do I instantiate it? The
best I can figure is using View.inflate in the ListAdapter's getView
method, but this throws a

You could use layout_weight. Give the elements that don't change size
a weight of 0 and the one that does a weight of 1. The two 0-weight
views will be their correct height and the 1-weight view will expand
to fill the rest of the space

I have an app that displays a camera picture as part of it, but if the
picture is in memory I get an out of memory exception when an
allocation of any size happens no matter what. If the app uses a
seekbar in addition to my PictureView the ~900 bytes it allocates are
too much. I even tried to lo
Whatever SurfaceHolder you gave the camera needs to have its type set
to SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS. This may not be your

I have an extension to ImageView that I would like to draw by manually
altering the ImageMatrix. When I set the View's scaling type to
matrix however, changing the matrix has no effect on the image. If I
put it into a different mode, say center, changing the matrix does

I'm having a similar issue with an ImageView based class that uses
Matrix transformations. I update the Matrix with setImageMatrix, but
the view does not update. how can I get the view to update?

Also there's overhead associated with putting the code into the middle
of the draw loop. The speed at which this loop runs will depend on
more than just the code you want to target. Maybe alter it so that it

I think I might go the offscreen buffer route and render when I can,
as FPS doesn't matter to me in the slightest. I'm looking at creating
a virtual canvas to draw to, but I'm not sure what to do with the
YCbCr array that can get it into a usable form. What would you
suggest I do with the array?
I'm working on an app that requires the user to be able to read some
text that's in the camera's preview images. The camera has plenty of
resolution for the range I'm looking at, but when it's shrunk down to
fit on the phone's display it's completely unusable. What I want to
