sd-card

Is it true that the file path to external SDCard on Android devices are always "/storage/extSdCard" ? If not, how many variations are there? I need it for my App to test the availability of external SDCard. I am using Titanium, it has a method Titanium.Filesystem.isExternalStoragePresent( ) but it always return true even external SDCard is not mounted. I think it detect SDCard at local storage thus return true. But what I really want is detect whether physical SDCard is mounted or not. Can I do this by detecting the existence of file "/storage/extSdCard" alone? Thanks. Digoun Is it true that

I am trying to save a file to my SDcard on my Samsung Galaxy Nexus running 4.2.2. From my app I am using Environment.getExternalStorageDirectory() But it returns /storage/emulated/0/ Which is not where my SDcard information is located to. Is there any working method I can use to get the correct path to my SDcard? Actually, that is the correct location. From android 4,2 onwards, Google introduced multiple user accounts. Every user has his/her own external storage, which has the user ID in the path to maintain uniqueness. The primary (default) user's ID is 0. So you get /storage/emulated/0/ as

I've had a look at Stack Overflow question Initialization of a microSD card using an SPI interface and didn't see any answers that matched my issue (that is, things I haven't already tried). I have a similar issue where I'm trying to access a SD card through a microcontroller's SPI interface (specifically an HC908 ). I've tried following the flow charts in the Physical Layer Simplified Specification v2.00 and it seems to initialize correctly on Transcend 1 GB & 2 GB and an AE&C 1 GB card. But I'm having problems on three other random cards from my stash of old cards that I've used on my camera

As the database in my app grows, it is going to require more and more of the internal phone space. There isn't any sensitive/private data in the DB, so I'm interested in moving it to the SD card. I'm using SQLiteOpenHelper to assist with the database work. It's my understanding that you can't use this for DB-access on the SD card as you can't define the DB path. However, there are some (very poor) examples on the Internet that suggest you can override this limitation. However I've never gotten one of those code samples to compile. Is it possible? And if so--HOW! Please note that Froyo's "apps

I'm trying to make an mp3 player app, and when I run it from my phone it only reads MP3's that are present on the SD card itself. It does not read any MP3's from the subfolders that are present in the card. I want it to display all the MP3's present in the SD card(including the subfolders). public class SongsManager { // SDCard Path final String MEDIA_PATH = new String(Environment.getExternalStorageDirectory().getPath()); private ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>(); // Constructor public SongsManager(){ } /** * Function to read all mp3 files

Link :I worked on based on this Link I added this line to find the size (both Internal and External) size, return availableExternalMemorySize/(1024*1024); I tested in my Tablet. I am getting both Internal and External SD card size as, In Internal Storage: Total Memory --1007 Available Memory --683 In External Storage: Total Memory -- 1763 Available Memory -- 1554 But in Tablet, I saw settings. An External Storage size has 8GB. But it is showing me 1.7 GB around when I tested via programmatically. What is the procedure to find an External storage size? To get the external SD card's available
