Attempt to invoke virtual method on null object reference SQLite

Trying to access pieces of information in my database, depending on whether the email address matches, however I keep getting the error message:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.wolfe_000.final_final_zeno/com.example.wolfe_000.final_final_zeno.Main}: java.lang.NullPointerException: Attempt to invoke virtual method 'android.database.sqlite.SQLiteDatabase android.content.Context.openOrCreateDatabase(java.lang.String, int, android.database.sqlite.SQLiteDatabase$CursorFactory, android.database.DatabaseErrorHandler)' on a null object reference

Here is the function that is causing the problem:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Name = (TextView) findViewById(R.id.Username);
    Weight = (TextView) findViewById(R.id.textView11);
    Goal = (TextView) findViewById(R.id.textView26);
    img = (ImageView) findViewById(R.id.ProPic);

    DatabaseOperations DOP = new DatabaseOperations(CTX);
    Cursor CR = DOP.getInformation(DOP);
    CR.moveToFirst();
    do
    {
        if(EMAIL.equals(CR.getString(2)))
        {
            NAME = CR.getString(0);
            WEIGHT = CR.getInt(3);
            GOAL = CR.getInt(4);

        }
    }while(CR.moveToNext());

    Name.setText(NAME);
    Weight.setText(Integer.toString(WEIGHT));
    Goal.setText(Integer.toString(WEIGHT-GOAL));
}
