Question: when i was inserting the bitmap image to files directory, it showing file not found exception and it is showing Is a Directory.

Here is my code:

```
            File mFolder = new File(getFilesDir() + "/sample");

            if (!mFolder.exists()) {
                mFolder.mkdir();
            }
             FileOutputStream fos = null;
             try {
                 fos = new FileOutputStream(mFolder);
                 bitmap.compress(Bitmap.CompressFormat.PNG,70, fos);

                 fos.flush();
                 fos.close();
              //   MediaStore.Images.Media.insertImage(getContentResolver(), b, "Screen", "screen");
             }catch (FileNotFoundException e) {

                 e.printStackTrace();
             } catch (Exception e) {

                 e.printStackTrace();
             }

```

Answer: 
Use `file.createNewFile()` if you want to make a file and not a directory.
You may also need to use `mkDirs()` if the path doesn't exist either.
```
File sdcard = Environment.getExternalStorageDirectory();
File dir = new File(sdcard.getAbsolutePath() + "/text/");
dir.mkdir();
File file = new File(dir, "sample.txt");
FileOutputStream os = null;
try {
    os = new FileOutputStream(file);
    os.write(enterText.getText().toString().getBytes());
    os.close();
}
catch (IOException e) {
    e.printStackTrace();
}

```
