android - 通过 Intent 打开Samsung S Planner时发生异常

我正在尝试打开已安装的日历应用程序，以便用户可以输入新事件。我使用以下意图在Nexus和许多其他设备上都能正常工作。

Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");

到目前为止，唯一的问题是安装了S Planner日历应用程序的三星设备。执行该意图后，LogCat中将显示以下异常，并且S Planner应用程序将严重崩溃（带有系统错误对话框）。

在尝试跟踪CalendarEventModel中发生的事情时，我没有在publicly available sources中找到任何线索。

有人知道如何正确启动S Planner来创建新事件吗？

最佳答案

我已经创建了用于创建日历事件的实用程序类，希望您发现它有用：

public class CalendarOrganizer {
    private final static int ICE_CREAM_BUILD_ID = 14;
    /**
     * Creates a calendar intent going from startTime to endTime
     * @param startTime
     * @param endTime
     * @param context
     * @return true if the intent can be handled and was started,
     * false if the intent can't be handled
     */
    public static boolean createEvent(long startTime, long endTime, String title, String description,
            String location, boolean isAllDay, Context context) {
        Intent intent = new Intent(Intent.ACTION_EDIT);
        int sdk = android.os.Build.VERSION.SDK_INT;
        if(sdk < ICE_CREAM_BUILD_ID) {
            // all SDK below ice cream sandwich
            intent.setType("vnd.android.cursor.item/event");
            intent.putExtra("beginTime", startTime);
            intent.putExtra("endTime", endTime);
            intent.putExtra("title", title);
            intent.putExtra("description", description);
            intent.putExtra("eventLocation", location);
            intent.putExtra("allDay", isAllDay);

//          intent.putExtra("rrule", "FREQ=YEARLY");
        } else {
            // ice cream sandwich and above
            intent.setType("vnd.android.cursor.item/event");
            intent.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, startTime);
            intent.putExtra(CalendarContract.EXTRA_EVENT_END_TIME, endTime);
            intent.putExtra(Events.TITLE, title);
            intent.putExtra(Events.ACCESS_LEVEL, Events.ACCESS_PRIVATE);
            intent.putExtra(CalendarContract.EXTRA_EVENT_ALL_DAY , isAllDay);
            intent.putExtra(Events.DESCRIPTION, description);
            intent.putExtra(Events.EVENT_LOCATION, location);

//          intent.putExtra(Events.RRULE, "FREQ=DAILY;COUNT=10")
        }
        try {
            context.startActivity(intent);
            return true;
        } catch(Exception e) {
            return false;
        }
    }
}
