Reading all of today's events using CalendarContract - Android 4.0+

由 旧街凉风 提交于 2019-11-30 07:13:34
问题 I'm trying to use Android's new calendar API to read all of today's calendar events. I'm have trouble finding the right selection on the database query to return all of the events. It seems that all recurring and all day events are left out of the selection. What selection args would permit me to obtain all of today's events from the calendar api? Here is my current attempt: Cursor cur = null; String selection = "((" + CalendarContract.Events.DTSTART + " >= ?) AND (" + CalendarContract.Events

Disable screenshots in android ics

由 北城余情 提交于 2019-11-30 04:26:06
For one of our secure apps, there is a requirement to disable the screenshot capability for the app in Android ICS. Is this possible on a non-rooted device? Thanks, Rajath Android Why don't you add this line in your activity class. This will do the trick. // This disables screen shot to be taken for current activity getWindow().setFlags(LayoutParams.FLAG_SECURE, LayoutParams.FLAG_SECURE); You may want to have a look at Mark Murphy's blog post . This will never be possible, period end of story. Its also possible for the owner of the device to obtain any encryption keys used by your application
