Android mkdir not making folder
Does the /mnt/sdcard/tallgrass/
directory exist? (I'm guessing not, but you never know.)
The File.mkdirs()
method will create all needed directories; mkdir()
will only create the last directory in the pathname.

Tonight I am currently having issues doing something that I thought would be simple... making a folder in /mnt/sdcard.
I have set the follow permission:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
My
Main.java
has the following to make the folder:public class Main extends TabActivity { static int index = 1; private static final String TAG = "Main"; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); File folder = new File(Environment.getExternalStorageDirectory () + "/tallgrass/images"); boolean success = false; if(!folder.exists()){ success = folder.mkdir(); } if (!success){ Log.d(TAG,"Folder not created."); } else{ Log.d(TAG,"Folder created!"); } }
I get the "Folder created!" message in my log but when I check both
/mnt/sdcard
and/sdcard
neither one has the folder. I have tried calling:Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())
and it returns true. I just can't figure this one out because all signs are pointing that it should work. I have also tried it with the phone disconnected from the PC in case the SD card was mounting or something as I am currently using my phone instead of the emulator for developing. Speaking of which, does
debuggable
totrue
maybe prevent it from making the folder?Thanks!
