解决方法
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state))
{
//SDcard is available
File f=new File("/sdcard/test.txt");
if (!f.exists())
{
//File does not exists
f.createNewFile();
}
//take your inputstream and write it to your file
OutputStream out=new FileOutputStream(f);
byte buf[]=new byte[1024];
int len;
while((len=inputStream.read(buf))>0)
out.write(buf,len);
out.close();
inputStream.close();
System.out.println("\nFile is created...................................");
}
