How can I get this path by something like Environment.getExter

Answer 1

On some devices (for example samsung galaxy sII )internal memory card mabe be in vfat. In this case use refer last code, we obtain path internal memory card (/mnt/sdcad) but no external card. Code refer below solve this problem.

static String getExternalStorage(){
         String exts =  Environment.getExternalStorageDirectory().getPath();
         try {
            FileReader fr = new FileReader(new File("/proc/mounts"));       
            BufferedReader br = new BufferedReader(fr);
            String sdCard=null;
            String line;
            while((line = br.readLine())!=null){
                if(line.contains("secure") || line.contains("asec")) continue;
            if(line.contains("fat")){
                String[] pars = line.split("\\s");
                if(pars.length<2) continue;
                if(pars[1].equals(exts)) continue;
                sdCard =pars[1]; 
                break;
            }
        }
        fr.close();
        br.close();
        return sdCard;  

     } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return null;
}
