Question

ComponentName componentName = new ComponentName("com.android.calendar",
        "com.android.calendar.LaunchActivity");
if (componentName != null) {
    Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
    // com.android.providers.calendar.CalendarProvider
    intent.setFlags(android.content.Intent.FLAG_ACTIVITY_NEW_TASK);

    intent.setComponent(componentName);
    startActivity(intent);
} else {
    Log.i("", "98979");
}

LogCat returns the following error:

ERROR/AndroidRuntime(601): Caused by: android.content.ActivityNotFoundException:
Unable to find explicit activity class {com.android.calendar/com.android.calendar.LaunchActivity};
have you declared this activity in your AndroidManifest.xml?

What is the new calendar address or package?

Answer 1

try this,

its working for me, to open google Calendar, not phone’s

 Intent i = new Intent();

//Froyo or greater (mind you I just tested this on CM7 and the less than froyo one worked so it    depends on the phone...)
cn = new ComponentName("com.google.android.calendar", "com.android.calendar.LaunchActivity");

 //less than Froyo
 cn = new ComponentName("com.android.calendar", "com.android.calendar.LaunchActivity");

i.setComponent(cn);
startActivity(i);

i am also searching to open phones calendar
