Android AlarmClock ACTION_SET_ALARM intent produces exception

问题

The given example produces an Exception (android.content.ActivityNotFoundException: No Activity found to handle Intent)

Intent i = new Intent(AlarmClock.ACTION_SET_ALARM); 
i.putExtra(AlarmClock.EXTRA_MESSAGE, "New Alarm"); 
i.putExtra(AlarmClock.EXTRA_HOUR, hours); 
i.putExtra(AlarmClock.EXTRA_MINUTES, mins); 
startActivity(i); 

on my SGS2 Android Version 2.3.3. Do you have any ideas, what can be going wrong? An another intent request (e.g. selecting a contact from the address book) works fine.

Thank you, Artjom

The device does not support that activity. This is not unheard of. Either catch the exception and let the user know, or use PackageManager and queryIntentActivities() to see if anything will respond to your Intent in advance of calling startActivity().

You need to set permission in manifest file also.

<uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>
