Question

I’m trying to create a generic login screen for Android. I’d like the program to check if the username and password (currently hardcoded) is listed. If the account is listed, you will be taken to a new screen called menuTest. I have the basic login working (without activity or intents). But when I try to add the intents, I get an error. How can I fix this? Below is my sample code.

Below are a few links containing screenshots of crash and logcat (edit: links are dead).

try changing Intent loginIntent = new Intent(this, menuTest.class); to Intent loginIntent = new Intent(Login.this, menuTest.class);
