I can't mount my sd card on the emulator and it gives me only a read option for the sd card as shown below :

Open the shell. Open your prompt, type:

adb shell

Then, remount your sdcard with rw permissions.

mount -o remount rw /sdcard

EDIT

sdcard without permissions:

i get an error saying that device not found. I want to do this on my emulator not on the real device – Suhail Gupta May 21 '12 at 05:18
You need to launch your emulator before opening the shell for your emulator. You can access the shell for your emulator in the same manner you can do for your device. Do not connect your device while running the adb command. Power on your emulator then go for the above steps. – Kazekage Gaara May 21 '12 at 05:20

your sdcard is not mounted properly. – Kazekage Gaara May 21 '12 at 05:36
just run `mount` on your shell to know if your sdcard is mounted. – Kazekage Gaara May 21 '12 at 05:37
Yup. Your sdcard isn't mounted. – Kazekage Gaara May 21 '12 at 06:01
Have you added a sdcard to your emulator? Check once by opening AVD Manager > Selecting your device > Details. – Kazekage Gaara May 21 '12 at 06:03
but i mentioned the sd card size while making the virtual device a.k.a emulator. How can i mount now ? – Suhail Gupta May 21 '12 at 06:03
If you have a sdcard, simply type `mount /sdcard` in your shell. – Kazekage Gaara May 21 '12 at 06:04
You have a sdcard, just try the `mount` command I just gave you. – Kazekage Gaara May 21 '12 at 06:06
i don't know why,but i have started getting `error:device offline` after i run the `mount /sdcard` the eclipse doesn't show anything in the file-explorer and log cat doesn't logs ! – Suhail Gupta May 21 '12 at 06:30
restart your `AVD` or create a new `AVD` as the other answer suggests. – Kazekage Gaara May 21 '12 at 06:32

[now when i have read-write permissions i can't see the images on the emulator i have pushed . what could be the reason ? I can see `IMG_201`,the image that i captured using the emulator but can't see the `bea.jpg` and `amsterdam.jpg` that i have pushed onto the emulator](http://i45.tinypic.com/33yt9ut.jpg) – Suhail Gupta May 22 '12 at 12:43
I don't have much of an idea about it. Post this as a new question, maybe someone might be able to help. – Kazekage Gaara May 22 '12 at 13:42

Make sure that you can created the SDCard for the Emulator by giving its size under

SD Card - Tab and also you have added SD Card Support to your device under Hardware - Tab

I would insist you to try to create another AVD and try it. – Lalit Poptani May 21 '12 at 05:35

use your AVD manager and specify that the AVD target has an sd card on the virtualization. Also Google limits the emulated card to 50Mb, at least they used to. So just open eclipse, bring up your AVD manager from the menu bar and edit the target AVD emulation to have a card installed, then input write permission in your android manifest file for permission, should work fine from there.
