Justin,
In case of the calendar application the activities
<activity android:name="MonthActivity" android:label="@string/
month_view"
android:theme="@style/CalendarTheme" />
<activity android:name="WeekActivity" android:label="@string/
week_view"
android:theme="@style/CalendarTheme" />
<activity android:name="DayActivity" android:label="@string/
day_view"
android:theme="@style/CalendarTheme" />
<activity android:name="AgendaActivity" android:label="@string/
agenda_view"
android:theme="@android:style/Theme.Light"
android:exported="true" />
have no action assigned. When you try to start this activities from
SDK level you get the permission error because you don't have the
correct permissions.
When you start the calendar application with
calendarIntent.setClassName
("com.android.calendar","com.android.calendar.LaunchActivity");
the calendar app is brought to the foreground at the last activity it
was. If you left the calendar app in the MonthActivty, it will be in
the monthActivity after executing the command above.
I assumed that you can use the PackageManager to find out about
activities but
PackageInfo packageInfo = pm.getPackageInfo
(taskInfo.topActivity.getPackageName(), GET_ACTIVITIES);
in case of the calendar application returns NULL.
I noticed that the approach you took works fine for 3rd party apps and
some of the system apps but not all system apps ...
