You are probably passing/getting a null tableName.
Try this:
if(b!=null){
tableName=b.getString("table_name");
catName=b.getString("level_name");
Log.d("Table Name",tableName);
Log.d("Level Name",catName);
}

Try this please:
public void addQuestionsUnit1(QuestionUnit1 quest){

db.beginTransaction();

Then finally the method for creating the signature:

signImage = (ImageView) findViewById(R.id.custimagesig);
b1.setOnClickListener(onButtonClick);
Button.OnClickListener onButtonClick = new Button.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(CreateOrEditActivity.this, CaptureSignature.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);
signImage.setImageBitmap(Bitmap.createScaledBitmap(b, 625, 625, false));
}
Not sure if if the CaputureSignature.class is needed? This is only to bring up the "Sinature Pad" for the customer to sign on.
I am not sure what i am doing wrong here? Could some one please help?
Please let me know if you require more information.
Thanks Guys :-)

Actually you are trying to get String of image but you saved a byte as blob so in place of String custsign = rs.getString(rs.getColumnIndex(ExampleDBHelper.PERSON_SIGNATURE)); you should try byte[] custsign = rs.getBlob(rs.getColumnIndex(ExampleDBHelper.PERSON_SIGNATURE)); and parse byte[] in bitmap and set to imageView.
Edit
byte[] custsign = rs.getBlob(rs.getColumnIndex(ExampleDBHelper.PERSON_SIGNATURE));
if(custsign.length>0){
Bitmap bitmap = BitmapFactory.decodeByteArray(custsign, 0, custsign.length);
imageView.setImageBitmap(bitmap);
}else{
Toast.makeText(this,"Image is Not Fetching ",Toast.LENGTH_LONG).show();
}

In SimpleCursorAdapter.java, you have a method bindView() which overrides the same method from its parent class, but you don't put any code in that method. Deleting the method should fix the error. But if you plan to override how binding works in that method, you may want to put some code in there starting with something like
super.bindView(view, context, cursor);

and my Main Java code:

public void Set_Referash_Data() {
contact_data.clear();
for (int i = 0; i < contact_array_from_db.size(); i++) {
String title = contact_array_from_db.get(i).getTitle();

String Price = contact_array_from_db.get(i).getPrice();

cnt.setDescription(Description);
cnt.setPrice(Price);

contact_data.add(cnt);
}
dbHelper.close();
cAdapter.notifyDataSetChanged();
list.setAdapter(cAdapter);
Log.e("Adapter issss ...", String.valueOf(cAdapter));
}
I found one example about how to delete title but it's not working.
How could I delete user by position in listview 'onclick' listener?
Any help would be great, thanks

db.delete(DATABASE_NAME, "username = ?", new String[] { userName });
You'll need to use the table name here, if all else is correct.
