Question

i have a very small problem. I am writing a file to sdcard. I’l show you two code, one code works and other doesn’t. It looks like this:
First one,

new FileOutputStream("/sdcard/HelloWorld.txt")

This works fine and creates a HelloWorld.txt file in sdcard.

Now second one,

  new FileOutputStream(android.os.Environment.getExternalStorageDirectory()+java.io.File.separator + "filetest" + java.io.File.separator + "HelloWorld.txt")

This throws error “/mnt/sdcard/filetest/HelloWorld.txt (No such file or directory)“.
I want to know why because i have mnt/sdcard path on my device, is it that it cannot find filetest folder if yes then isn’t it supposed to create filetest folder if its not created before.

Thanks.

Answer 1

First Make a directory of filetest if its not available,

File file = new File(android.os.Environment.getExternalStorageDirectory()+java.io.File.separator + "filetest");

file.mkdir();

Then execute your code…

OR

File f =    new File(android.os.Environment.getExternalStorageDirectory()+java.io.File.separator + "filetest" + java.io.File.separator + "HelloWorld.txt");

    if (!f.getParentFile().exists());
    {
        f.getParentFile().mkdir();
    }
