My Fragment doesn't get destroyed after it is recreated

I am developing a gallery application, I display all the icons from the external storage into my application. I followed the tutorial from the below link and it is working.
https://deepshikhapuri.wordpress.com/2017/03/20/get-all-images-from-gallery-in-android-programmatically/
Now in addition to this, I provide an option for the user to take a picture from the application and save it to the gallery. When the picture is taken using the Camera intent, the image gets actually saved in the gallery. But I have to intent to another fragment and come back to the Gallery to see the picture I have taken.
To see the changes immediately, onActivityResult() of the Camera intent, I am recreating the fragment. But the problem occurs when we click the back button. The recreated fragment stays in the backstack forever. I am brain faded searching for answers. Any help is appreciated.
Please find below what I have tried so far.

App crashes when trying to load image from SQLite Database

In my app I have a few EditText's that users can fill in and hit save and it will save those details. I also have a button that opens up a blank canvas for the user to sign on (digital signature). Then when the user selects save the image is displayed in an ImageView, and then finally the user can tap on save again to save the form with the image. All of this works, but as soon as the user selects save to save the form the app crashes with the following error:
java.lang.NumberFormatException: Invalid int: "android.widget.ImageView$ImageViewBitmapDrawable#efa14f0"

Here is the code I use:
FormDBHelper.class
public static final String USER_SIGNATURE = "signature";
....
USER_SIGNATURE + " BLOB, " +
....
public boolean insertPerson(String customername,
......
byte customersign, int
jobnumber) {
SQLiteDatabase db = this.getWritableDatabase();

contentValues.put(USER_SIGNATURE, customersign);
contentValues.put(USER_JOB_NUMBER, jobnumber);
db.insert(PERSON_TABLE_NAME, null, contentValues);
return true;

public boolean updatePerson(Integer id,

contentValues.put(PERSON_JOB_NUMBER, jobnumber);
db.update(PERSON_TABLE_NAME, contentValues, PERSON_COLUMN_ID + " = ? ", new String[]{Integer.toString(id)});
return true;
}
Then in my CreateFormActivity.class
private FormDBHelper dbHelper;
EditText nameCustomer;
....
ImageView signatureImage;
Button saveButton;
LinearLayout buttonLayout;
Button editButton, deleteButton;
int personID;
.....
nameCustomer = (EditText) findViewById(R.id.editCustName);

buttonLayout.setVisibility(View.VISIBLE);
rs = dbHelper.getPerson(personID);
rs.moveToFirst();

#Override

return;
case R.id.editButton:

buttonLayout.setVisibility(View.GONE);
nameCustomer.setEnabled(true);
nameCustomer.setFocusableInTouchMode(true);
nameCustomer.setClickable(true);
....
signatureImage.setEnabled(false);
signatureImage.setFocusableInTouchMode(true);
signatureImage.setClickable(false);
......
public void persistPerson() {
if (personID > 0) {
if (dbHelper.updatePerson(
personID,
nameCustomer.getText().toString(),
....
(byte) Integer.parseInt(signImage.getDrawable().toString()),
....
Integer.parseInt(jobEditText.getText().toString()))) {
Toast.makeText(getApplicationContext(), "Form Update Successful", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getApplicationContext(), FragmentJob.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
} else {
Toast.makeText(getApplicationContext(), "Form Update Failed", Toast.LENGTH_SHORT).show();
}
} else {
if (dbHelper.insertPerson(
nameCustomer.getText().toString(),
....
(byte) Integer.parseInt(signImage.getDrawable().toString()), **this is where it crashes (413)**
Integer.parseInt(jobEditText.getText().toString()))) {
Toast.makeText(getApplicationContext(), "Form Inserted", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "Could not Insert Form", Toast.LENGTH_SHORT).show();
}
Intent intent = new Intent(getApplicationContext(), FragmentFormJob.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}
}
This is my code (in the same class) where the user taps on the button to create their signature:
Button.OnClickListener onButtonClick = new Button.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(CreateFormActivity.this, CaptureUserSig.class);
startActivityForResult(i, 0);
}
};
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
if (resultCode == 1) {
Bitmap b = BitmapFactory.decodeByteArray(
data.getByteArrayExtra("byteArray"), 0,
data.getByteArrayExtra("byteArray").length);
signatureImage.setImageBitmap(Bitmap.createScaledBitmap(b, 512, 512, false));
}
}
}
AFAIK this should work, unless I have made a mistake somewhere along the line. But for the life of me I can't seem to figure it out.

Hello I am getting this strange error in my app. The first time the application starts it runs however when I store a photo from the camera the app crashes and shows this log. The app takes photo from the camera or gallery and saves them in the database and displays the photo in a custom gridview.

Can someone please help. I searched but I could not find a solution

Your problem is that you are storing path in CAMERA_PATH, which is string and trying to get a Blob. There is a type mismatch and thats why the error is thrown.
You need to insert a blob in the CAMERA_PATH before you try retrieving a blob from there.

I am trying to export a single contact from the address book to .vcf. Where am I going wrong?

Try with this dude it will open your contact jusr pass contactId in this
Intent intent = new Intent(Intent.ACTION_VIEW);
//pass your contact id
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, String.valueOf(contactId));
intent.setData(uri);
mcntxt.startActivity(intent);
