I have been using the debugger to step through and the error is caused by the line:
db.delete("TempCourses", null, null); The error occurs whether I check if there is data in the table or not. I guess I could try and drop the table everytime I want to clear it but it certainly seems I should be able to delete the contents. I have also tried the following: String sql = String.format("DELETE FROM TempCourses WHERE _id > 0 "); db.execSQL(sql); I get the same NullPointerException error on the line: db.execSQL(sql); Thanks...
