Do you add <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> in AndroidManifest file ?

UPDATE: if you want to save to internal storage, you can use below code:

private void storeImage(Bitmap image) {
    try {
        String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmm").format(new Date());
        String mImageName="MI_"+ timeStamp +".jpg";

        FileOutputStream fos = openFileOutput(mImageName, MODE_PRIVATE);
        image.compress(Bitmap.CompressFormat.PNG, 90, fos);
        fos.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

it will save to data/data/your_packagename/files

You can use below code to save bitmap to internal storage.It will create dirctory in internal storage imageDir , and you have to give the name to save your image i.e profile.jpg

 private String saveToInternalStorage(Bitmap bitmapImage){
            ContextWrapper cw = new ContextWrapper(getApplicationContext());
             // path to /data/data/yourapp/app_data/imageDir
            File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
            // Create imageDir
            File mypath=new File(directory,"profile.jpg");

            FileOutputStream fos = null;
            try {           
                fos = new FileOutputStream(mypath);
           // Use the compress method on the BitMap object to write image to the OutputStream
                bitmapImage.compress(Bitmap.CompressFormat.PNG, 100, fos);
            } catch (Exception e) {
                  e.printStackTrace();
            } finally {
                try {
                  fos.close();
                } catch (IOException e) {
                  e.printStackTrace();
                }
            } 
            return directory.getAbsolutePath();
        }
