The most likely reason for it to be slow is that it is a huge image
you are loading. You could also try making it a PNG -- since pretty
much all of the UI is PNG images, those are loaded into each app as
they start, so the performance of that is clearly acceptable -- though
as far as I know JPEG
Using scale(0.5f, 0.5f) just means that the text will be drawn at half
its size, not that it will be drawn to fit in a rectangle that is half
the size of the screen. It depends on the length of the text you are
drawing, the font size and the type face you are using.

It is actually not very difficult to implement a list of checkboxes.
The key is to write a custom Adapter that keeps track of the selected
items (using a SparseBooleanArray for instance.) I wrote such an
adapter as an ApiDemo recently, I'll try to find the code and paste it
here. Note that the
It also supports u/u, but I don't think there's any way to set a
color only for specific words in the string without implementing your
own TextView. Either that or string together multiple textviews with
appropriate colors, but that probably isn't the best idea.

Hi Juan,
Start the second instance and run the command
adb -d 2 install ANDROID_SDK_PATH/samples/ApiDemos/bin/ApiDemos.apk
Note that you only need the -d 2 argument if you start the first
emulator first.

Is it possible to resume a background activity using an intent?
When I register a notification in the status bar and clicked on it an

Please help.
Thanks a lot.
here is the demo code what you want.

Hi All,
Is it common to use ScrollView as the parent layout for scrolling on a
screen? My screens normally go beyond the view of the screen.
Especially when I test using the QVJA emulator skins. Below is
example of what most of my layouts for app look like.
?xml version=1.0 encoding=utf-8?
I am having the same issue...let me know if you figure out a
solution...

Also, try rotating the device (Ctrl-Alt-Pg. down). The ratio (frames/
sec) is much slower in landscape mode than in portrait mode.
I suppose it is just an emulator issue and it will not be a problem
with the actual devices, so I'm not too much worried about it...

It's because the Android code isn't really Java, it's Dalvik, and the
Android emultator makes you report those things to the Dalvik output.
You yourself listed the process to print errors there, I suggest you
use it. ;)
