My aim is to save a drawing from my fragment to my android device. I have been trying to use the same approach in Activity class and it work. However when i try to use it in fragment class, it does not worked.

The app didn't crash it just display this error log.

Here is the code:

View content = v;
content.setDrawingCacheEnabled(true);
bitmap = content.getDrawingCache();
File file;

String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/req_images");
myDir.mkdirs();

Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-" + n + ".jpg";
file = new File(myDir, fname);
//Log.i(TAG, "" + file);

if (file.exists())
    file.delete();

try {
    FileOutputStream out = new FileOutputStream(file);
    bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
    out.flush();
    out.close();
} catch (Exception e) {
    e.printStackTrace();
}

it could be either you are missing read external storage permission or */storage/sdcard0/req_images/Image-296.jpg* file is missing — Illegal Argument, Nov 28 '14 at 04:19

Instead of

   myDir.mkdirs();

use

file.mkdirs();

mkdirs creates only parent directories, so use it on file rather than directory.

Edit: Then maybe add this too

file.createNewFile();

I think you are already deleting the file after creating it and then you are trying to convert the non-exists file into the bitmap which is not valid. That is why you are getting an error no such file or directory found.

Just remove the line file.delete(); from your code and try out.

Thank you very much for the answer... i finally don't get any error.. however the i can't find the picture either in gallery nor file manager.. – Azharan Nov 28 '14 at 07:00
@Azharan You have create new file again from your bitmap object and save it into sdcard then only you will be able to get it. – GrIsHu Nov 28 '14 at 07:28
Make sure you have given write external storage permission in your manifest file. – GrIsHu Nov 28 '14 at 07:40
Thank you very much for helping out with this one. Actually the problem is on the external storage permission. I didn't enable it at first. However, i still need the **file.delete();** because if not, only the folder will be created but there is no image in it. Thank you very much again @GrlsHu – Azharan Nov 28 '14 at 07:59
@Azharan Glad to help always :) – GrIsHu Nov 28 '14 at 08:06
