 Anybody know what's up with this stacktrace? I see it often during
debugging, but none of it is in my code. When it comes up it seems the
debugger fails to attach. Is this an android bug?

1. Bitmaps (.bmp) don't show up in 'Pictures' when on SDCard


For the purpose of testing I need to store some small (20x20px)
bitmaps on the SDCard of the emulator.

If I store the files in jpg format then media scanner picks them up
and I can view them with the stock 'Pictures' application.

When I use the '.bmp' file format as created via the JAI based tool I
am testing, the files do not show up on the phone, a look at the file
explorer shows the files to be there next to their jpg equivalents on
the SDCard under the folder pictures.

I mount the SDCard to add the files if it makes any difference.

I need the files to be lossless ARGB_8888 format, is there something
other than .bmp I can use?

Kind regards,


2. Dialog Theme problem when using dev option "Immediatly destroy activities"

I'm a little lost here... i got some wired behaviour when i enable the
above option.
I guess the problem is about recreating the dialog especially the
activity behind the dialog.

I did the following:
1. open an activity with dialog theme (OK)
2. obscuring the dialog activity with a fullscreen child activity so
it gets destroyed (OK)
3. moving back to the dialog activity (ERROR)

The dialog activity creates just fine but there seems to be a problem
in recreating
the activity behind the dialog activity. It doesn't mater if it's the
homescreen or for example
maps or calculator. The symptoms are always the same.

If i turn "Show Background" on it shows the No-Activity pattern behind
the dialog.

The de{*filter*} output suggests that there is some heavy creation/
deletion going on:

Some programs provide a little more output (Here Maps) but obviously
it runs in circles:
