I would like to write an application that is triggered when a calendar reminder occurs. I realize there is no officially documented way of doing this, but I have seen in the log that when my calendar alarm goes off on my phone (Droid X), AlertReceiver indicates that it has received an android.intent.action.EVENT_REMINDER:
01-03 11:03:00.029 D 1523 AlertReceiver onReceive: a=android.intent.action.EVENT_REMINDER Intent { act=android.intent.action.EVENT_REMINDER dat=content://com.android.calendar/129407058000 flg=0x4 cmp=com.android.calendar/.AlertReceiver (has extras) }
So, I set up a simple BroadcastReceiver:
package com.eshayne.android;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class CalendarTest extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
android.util.Log.i("CalendarTest", "CalendarTest.onReceive called!");
}
}
with this manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.eshayne.android"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.READ_CALENDAR" />
<application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true">
<receiver android:name="com.eshayne.android.CalendarTest">
<intent-filter>
<action android:name="android.intent.action.EVENT_REMINDER" />
</intent-filter>
</receiver>
</application>
<uses-sdk android:minSdkVersion="8" />
</manifest>
Unfortunately, when I put this on my phone and set up a calendar event with a reminder - when the reminder alerts, I still see the AlertReceiver log entry, but not mine.
I have also read here about some system intents that require registering via code rather than in the manifest. So, I tried the following instead:
package com.eshayne.android;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
public class CalendarTestDisplay extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
android.util.Log.i("CalendarTestDisplay", "received broadcast");
}
},
new IntentFilter("android.intent.action.EVENT_REMINDER"));
}
}
with this modified manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.eshayne.android"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.READ_CALENDAR" />
<application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true">
<activity android:name=".CalendarTestDisplay"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="8" />
</manifest>
with no better result.
Any ideas what I may be missing? Or any other ideas of how I might be able to capture calendar alarm occurrences?
Thanks, Ethan
You need to set data scheme to "content" in the intent filter.
Using manifest, add data element inside intent-filter
<receiver android:name="com.eshayne.android.CalendarTest">
<intent-filter>
<data android:scheme="content"/> <!-- this was missing -->
<action android:name="android.intent.action.EVENT_REMINDER" />
</intent-filter>
</receiver>
Using code, add datascheme in one function call
IntentFilter filter = new IntentFilter(CalendarContract.ACTION_EVENT_REMINDER);
filter.addDataScheme("content"); // this was missing
registerReceiver(myRemindersReceiver, filter);
