how to get file path from sd card in android

You can get the path of sdcard from this code:

File extStore = Environment.getExternalStorageDirectory();

Then specify the foldername and file name

for e.g:

"/LazyList/"+serialno.get(position).trim()+".jpg"

Environment.getExternalStorageDirectory() will NOT return path to micro SD card Storage.

how to get file path from sd card in android

By sd card, I am assuming that, you meant removable micro SD card.

In API level 19 i.e. in Android version 4.4 Kitkat, they have added File[] getExternalFilesDirs (String type) in Context Class that allows apps to store data/files in micro SD cards.

Android 4.4 is the first release of the platform that has actually allowed apps to use SD cards for storage. Any access to SD cards before API level 19 was through private, unsupported APIs.

Environment.getExternalStorageDirectory() was there from API level 1

getExternalFilesDirs(String type) returns absolute paths to application-specific directories on all shared/external storage devices. It means, it will return paths to both internal and external memory. Generally, second returned path would be the storage path for microSD card (if any).

But note that,

Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using getExternalStorageState(File).

There is no security enforced with these files. For example, any application holding WRITE_EXTERNAL_STORAGE can write to these files.

The Internal and External Storage terminology according to Google/official Android docs is quite different from what we think.

this code helps to get it easily............

Actually in some devices external sdcard default name is showing as extSdCard and for other it is sdcard1. This code snippet helps to find out that exact path and helps to retrive you the path of external device..

String sdpath,sd1path,usbdiskpath,sd0path; 

if(new File("/storage/extSdCard/").exists()) 
{ 
  sdpath="/storage/extSdCard/";
  Log.i("Sd Cardext Path",sdpath); 
} 
if(new File("/storage/sdcard1/").exists()) 
{ 
  sd1path="/storage/sdcard1/";
  Log.i("Sd Card1 Path",sd1path); 
} 
if(new File("/storage/usbcard1/").exists()) 
{ 
  usbdiskpath="/storage/usbcard1/";
  Log.i("USB Path",usbdiskpath); 
} 
if(new File("/storage/sdcard0/").exists()) 
{ 
  sd0path="/storage/sdcard0/";
  Log.i("Sd Card0 Path",sd0path); 
}
