Cant create a folder on sdcard - mkdir always return false

android, mkdir, sd-card

Solution

try this

//creating directory

File root = new File(Environment.getExternalStorageDirectory()
                + File.separator + "myDir" + File.separator);
root.mkdirs();
directoryCreated = new File(root, "filename");

//saving file

FileOutputStream out = new FileOutputStream(directoryCreated);
bm.compress(Bitmap.CompressFormat.JPEG, 100, out);
bm.recycle();

Problem

I've googled a lot of information about my issue but I really don't get what i'm doing wrong, I just want to save an image to sdcard in specific folder, but folder.mkdir() always return false and I get an exception ``` java.io.FileNotFoundException: /mnt/sdcard/sakhcomcache/tv/1.gif: open failed: ENOENT (No such file or directory) ``` and of course I have a permission in my manifest ``` <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> ``` Here is my code ``` ..... private final static String CACHE_PATH = "/sakhcomcache/"; public final static String CACHE_FOLDER_TV = "/tv"; ..... public static void saveImageOnSDCard(final Bitmap image, final String cacheFolder, final String name) { new Thread(new Runnable() { @Override public void run() { try { File folder = new File(Environment.getExternalStorageDirectory() + CACHE_PATH + cacheFolder); if (!folder.exists()) { boolean create_succes = folder.mkdir(); //create_succes always false if(create_succes){ Log.i("create_succes", "create_succes"); } } File imageFile = new File(folder +"/"+ name.substring(name.lastIndexOf("/"))); if (!imageFile.exists()) { FileOutputStream out = new FileOutputStream(imageFile); image.compress(Bitmap.CompressFormat.PNG, 100, out); out.flush(); out.close(); Log.i("save succes", "save succes"); } } catch (Exception e) { e.printStackTrace(); } } }).start(); } ```
