AlarmManager Activity ( TRIGGERING Broadcast from here)

 package com.mainActivity;

    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;

    public class AlarmManagerActivity extends Activity {
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            Intent intent = new Intent(AlarmManagerActivity.this,BroadClass.class);
            intent.setAction("BROADCAST_ACTION");
            sendBroadcast(intent);
    }
    }

BroadClass Activity where I have defined the Broadcast Reciever

   package com.mainActivity;


    import android.app.Activity;
    import android.content.BroadcastReceiver;
    import android.content.Context;
    import android.content.Intent;
    import android.content.IntentFilter;
    import android.os.Bundle;
    import android.widget.Toast;



    public class BroadClass extends Activity {

        public BroadcastReceiver broadCast;

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);



            registerReceiver(new BroadcastReceiver() {

                @Override
                public void onReceive(Context arg0, Intent arg1) {
                    // TODO Auto-generated method stub

                    Toast.makeText(BroadClass.this, "SDK Manager Activity", Toast.LENGTH_SHORT).show();


myFunction();   //which i want to call

                }
            },new IntentFilter("BROADCAST_ACTION"));


        }


        @Override
        protected void onResume() {
            // TODO Auto-generated method stub
            IntentFilter filter = new IntentFilter();
            filter.addAction("BROADCAST_ACTION");
            registerReceiver(broadCast, filter);

            super.onResume();


        }

public void myFunction(){

//mycode here

    }

Kindly Help me..
Thanks in advance

Have you tried removing the BroadcastReceiver setup in onResume? You’re registering a new broadcastreceiver with an empty IntentFilter.

Remember, onResume is always run after onCreate, and in your case resetting the filter that was initially set.
