How Can I Get The Context Of Other Activity?

I'm working on the alarm app, and have trouble removing an existing alarm. I have to create the same pending intent to remove the alarm in the activity which lists all alarms in my

Solution 1:

This has nothing to do with contexts. The intent you schedule was created with getActivity. That is a different kind of intent than the one created with getBroadcast. You cannot use the latter to cancel the former.

(Edited to add code)

Intentintent=newIntent(
    getApplicationContext(),
    PushMainActivity.class);
PendingIntentpendingIntent= PendingIntent.getActivity(
    ListAddActivity.this,
    ALARM_CODE,
    intent,
    PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.cancel(pendingIntent);
