I wanted to know how to virtually create sd card in the emulator. Also I wanted to know where the app is really installed on the device.Is it in sd card or in internal memory..Thanks in advance
The above is answering your question related to your emulator SD card.
For installed app location follow this link:
Difference between Emulator and Real Device for Installed applications?
you can find your app stored location using DDMS in Eclipse. Usually you app will under
data->data->
If you want to use SD Card functionality in your Emulator then add new hardware SD Card Support. This option is avaible when you created new avd.

I'm trying to test a cocoonjs app I made on an Nvidia Shield. I was able to get to my app from an express server I had running on another pc and that worked fine but I'd like to be able to run the app locally off of an SD card in the shield.
I tried putting my .zip onto a micro sd and putting that into the shield but the launcher dosent show anything in the sd card list. I'm assuming that I have to somehow get the .zip file onto the internal shield sd card itself? Has anyone else done this before? Thanks in advance for the help and I apologize if I'm just missing something simple.
The only requirement is that the zip file should be on the root of the SD card.

How can I check if an SD card is present in an Android device? I'm especially interested in solutions for Android 2.2 and 2.3.
You can check if the external storage is avilable, but you do not know, if this is an SD-Card or not. Have a look at the documentation
I want to make an android application which should be installfrom sd card. i means as the sd card inserted in mobile it should prompt for installing my application. (ex: As soon as we put the tata photon or any other modem in to the system it prompt user to install the application)If i am right it is possible. so please guide me for the same. Please give the code as well.
thanks in advance :-)
If i am right it is possible
You are incorrect.
It is possible for an already-installed Android app to monitor changes in external storage and perhaps auto-install an APK. It is not possible for an uninstalled APK alone to do this, and approximately zero Android devices out of nearly one billion have this capability built in.
You can make a broadcast receiver which will fire when memory card will inserted.Just capture this event you can do what you want.
It may seem strange, but I wonder is an android app able to make the SD Card inside the device windows bootable? I thought of making the SD bootable and write ultimatebootcd to it. I did it through windows, but it would be so great if android can do it!
To make the SD card bootable, you have to modify the boot sector of the card. This can not be done from a standard Android application. If the Android device is rooted, it can almost certainly be done from a native Linux program, or an NDK program.
If the device is not rooted, you can probably not do what you want. As Chris Stratton commented, if the card is already made bootable, you could probably then change for instance what OS is booted up and how.
Say, there is startup code which loads and boots an OS, then you can change the configuration file for the bootloader. A starter: http://www.syslinux.org/wiki/index.php/Boot_an_Iso_image
I used Rufus and installed a syslynux on the SdCard from a PC running window 10.then I put the card back into the Moto phone. It's receiving files that I have moved from the internal storage to the card how ever I have not a chance to find out whether they Will open up In the PC or not.
I don't have an Android device to test this (yeah, i know. Android developer without an Android device) but i was wondering if in case there is either NO sdcard in the device, or the sdcard is full, when i need to store some data during the execution of my app, will it return an IOException? Or will it just store it automatically in the phone's memory? OR what happens in this situation, and what are the best steps to pursue?
you could check if the sd card is mounted or not
Is there a way to tell if the sdcard is mounted vs not installed at all?
EDIT:
you can check the availaible space in your phone (sdcard/internal)
How to Check available space on android device ? on SD card?
you might find this useful too.. An IOException IS thrown if you exceed the storage limit.
IOException is thrown when SDCard is full
You can setup the emulator so it uses a SD card and then fill it up with for example "dd". This should give you an environment you can use to test your application in the case when there is no room left on your SD card.
