I'm working on a project for my A Level controlled assessment. For context, I am creating an application to manage a Scout group, and I am currently working on allowing the user to create a record containing Scout details, and insert it into a database. This is my first project I've created based around databases, and I have never used Android Studio, XML or Java before, nor am I being taught them - this is all being done off my own back.
For this reason, I'm having a fair bit of trouble. I am having trouble inserting a record into a database - I have followed a couple of different tutorials, but it still doesn't seem to be working. The IDE itself isn't giving me an error, however when I click the "save" button on a device running my application, it crashes. I have absolutely no idea where the error could be, so I've attached a fair bit of code from the database manager and the "Add a Scout" screen.
Many thanks in advance.
UPDATE
I've been told that I should insert my logcat trace into the question - it's below. I had to remove the other code to make space for this - if someone still needs it, just let me know.
UPDATE #2
Again, I've removed things from the previous update so I don't exceed the character limit.
The IDE is telling me that the issue causing the crash is with the following line:
lblError.setText("Error - please fill all necessary fields");
I will attach the full Java code for this screen below, so it can be seen in context.
I can't see anything wrong with this line - is anybody able to help?
Many thanks in advance.
