 Hi Buddies,

I wanna get understood that why in emulator "dev/eac" is the device of

as I know, in external/qemu/audio, there is all kinds audio drivers,
such as oss, alsa,

but I am very curious why in the android linux system, the "dev/eac"
is connected with those drivers.

Anybody can give me some light on that?

 Hi David,

Thanks for your reply.

When I study the code in frameworks\base\libs\audioflinger
\AudioHardwareGeneric.cpp, I saw it does open the device node "dev/
eac" to get a File descriptor. Therefore , the question is how "/dev/
eac" is connected with the host linux's sound system. I have read the
code in external/qemu/hw/goldfish_audio.c, but I still can not figure
out how the device node "/dev/eac" in emulator's linux system is
connected with host linux's sound system.

1. Query sent SMS fro

Hello, when I send an SMS on my emulator, it goes to the content
content: / / sms / sit


So I want to get these SMS's sent from the content provider. But I do
not know how to do this. I know I should have the query () method and
then call it in the place where I want to search. I did this:

ContentResolver cr = getContentResolver ();// Getting object
final Uri CONTENT_URI Uri.parse = ("content: / / sms / sent");
public void myClickHandler (View view) (

        switch (view.getId ()) (

        R.id.btnVerSms case:
            cr.query (CONTENT_URI, null, null, null, null);



Once you have done a search, how do I list it in a ListView?
Would someone help me in detail? If you can, thank you.
