    Notification service using OpenWatch, Tasker and PHP

    Setup Tasker

    1. create a new time-based profile, let it run every 5 minutes or so
    2. add the following actions:
      1. Net → HTTP Get
        • Server:Port: www.example.org (<your webserver>)
        • Path: /notifier/notify.php (adapt according to your setup)
        • Attributes: <leave empty>
        • Timeout: 10 (default)
        • Mime Type: text/plain; charset=utf-8
        • Output File: <leave empty>
      2. Tasker → Stop
        • If: [X]
        • %HTTPD Isn’t Set
      3. Variable → Variable Split
        • Name: %HTTPD
        • Splitter:
        • Delete Base: [ ]
      4. Alert → Notify (you can omit this one if you like)
        • Title: Remote Notification
        • Text: %HTTPD1 %HTTPD2 (%HTTPD3 seconds ago)
      5. Misc → Action Intent
        • Action: com.smartmadsoft.openwatch.action.VIBRATE
        • Cat: None
        • Data: <leave empty>
        • Extra: line1:%HTTPD1
        • Extra: line2:%HTTPD2 (Note: There are 2 Extra input fields)
        • Target: Broadcast Receiver
    3. Done!

    Setup Server

    Put the following file onto a webserver capable of running PHP scripts (notify.php):

    <?php

    class DataStore {
    private $file;
    private $data = array(
    'entries' => array(),
    );
    private $modified = false;

    public function __construct( $filename = 'queue.json' ) {
    $this->file = getcwd() . '/' . $filename;
    if ( file_exists( $this->file ) ) {
    $this->load();
    }
    }

    public function __destruct() {
    if ( $this->modified ) {
    $this->save();
    }
    }

    public function add( $line1, $line2 ) {
    $this->data['entries'][] = array(
    'timestamp' => time(),
    'line1' => $line1,
    'line2' => $line2,
    );
    $this->modified = true;
    }

    public function getNext() {
    if ( $this->getCount() > 0 ) {
    $entry = array_shift( $this->data['entries'] );
    $this->modified = true;
    return $entry;
    }
    return array();
    }

    public function getCount() {
    return count( $this->data['entries'] );
    }

    private function save() {
    $json = json_encode( $this->data );
    file_put_contents( $this->file, $json, LOCK_EX );
    $this->modified = false;
    }

    private function load() {
    $fc = file_get_contents( $this->file );
    $this->data = json_decode( $fc, true );
    $this->modified = false;
    }
    }

    $ds = new DataStore();

    header( 'Content-Type: text/plain; charset=utf-8' );
    if ( isset( $_REQUEST['l1'] ) && isset( $_REQUEST['l2'] ) ) {
    // new notification ~~> store
    $ds->add( $_REQUEST['l1'], $_REQUEST['l2'] );
    } else {
    // else: Display next notification, if any
    $entry = $ds->getNext();
    if ( isset( $entry['timestamp'] ) ) {
    $span = time() - $entry['timestamp'];
    echo $entry['line1'] . '¶' . $entry['line2'] . '¶' . $span;
    }
    }

    Usage

    Under Linux, you can send a notification like this:

    wget -O - --quiet "http://www.example.org/notifier/notify.php?l1=This+is+line1&l2=And+this+is+line2"
