save picture in new directory

i want too save images in my own directory this is perhaps the directory on which the images are been saved

  Uri uriTarget = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, new ContentValues());

OutputStream imageFileOS;

and this is were i am giving my image uri Target where the image will going to be save

 imageFileOS = getContentResolver().openOutputStream(uriTarget);

                imageFileOS.write(arg0);

                imageFileOS.flush();

                imageFileOS.close();

how can i achive that by making my own directory and saving image there

The solution involving heavy Bitmaps is (IMHO) irrelevant when your phone or camera is taking JPEGs.

See the solution here for an almost instantaneous solution: https://stackoverflow.com/a/7982964/5426777

new FileOutputStream(myPath).write(byte[] myPictureCallbackBytes)

I have tried to take a picture and then crop it then stored it on SDCard.
Here are codes, maybe you will be inspired:


Take a photo:

        Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
        intent.putExtra("return-data", false);
        intent.putExtra(MediaStore.EXTRA_OUTPUT,
                Uri.fromFile(AVATAR_FILE_TMP));
        intent.putExtra("outputFormat",
                Bitmap.CompressFormat.JPEG.toString());
        intent.putExtra("noFaceDetection", true);
        startActivityForResult(intent, CODE_TAKE_PHOTO);


Then crop the photo:

if (requestCode == CODE_TAKE_PHOTO) {
    cropImage(Uri.fromFile(AVATAR_FILE_TMP));
}
public void cropImage(Uri uri) {
    Intent intent = new Intent("com.android.camera.action.CROP");
    intent.setDataAndType(uri, "image/*");
    intent.putExtra("crop", "true");
    // aspectX aspectY 是宽高的比例
    intent.putExtra("aspectX", 1);
    intent.putExtra("aspectY", 1);
    // outputX outputY 是裁剪图片宽高
    intent.putExtra("outputX", 400);
    intent.putExtra("outputY", 400);
    intent.putExtra("return-data", true);
    startActivityForResult(intent, CODE_CROP_IMAGE);
}


And at last, store the picture:

            Bundle extras = data.getExtras();
            if (extras != null) {
                Bitmap photo = extras.getParcelable("data");
                // civAvatar.setImageBitmap(photo); // 把图片显示在ImageView控件上
                FileOutputStream fos = null;
                try {
                    // store the picture
                    fos = new FileOutputStream(AVATAR_FILE);
                    photo.compress(Bitmap.CompressFormat.PNG, 100, fos);// (0-100)compress file.
                    AVATAR_FILE_TMP.deleteOnExit();
                } catch (FileNotFoundException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } finally {
                    IoUtils.closeSilently(fos);
                    finish();
                }
            }

And if you just store the picture, intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(AVATAR_FILE_TMP)); is OK.
