I have an android application that use SQLite database to store data. One of its field is match_date that contain the date with time.
What I want is to create notification that include the team names and the date after comparing the current date with the stored date in the database and if they match a notification must appear.
The application work perfectly but without getting any notification so where is my error an how to fix this error?
I will appreciate any help.
This is my database table:
CREATE TABLE [match_list] (
[_id] INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
[stad_name] VARCHAR(50) NOT NULL,
[team1] VARCHAR(50) NOT NULL,
[team2] VARCHAR(50) NOT NULL,
[stage] varchar(50) NOT NULL,
[match_date] DATETIME NOT NULL,
[flags1] CHAR(255),
[flags2] CHAR(255),
[group_team] CHAR(1));
