Call an activity using Alarm Manager & Broadcast Receiver - broadcastreceiver

Question

I'm trying to create an app that automatically make phone calls after regular intervals to a specified number. I'm using Alarm Manager and Broadcast Receiver for this purpose. Alarm Manager can't initiate PHONE CALL activity and application terminates giving an error.
Here's my code. I am new in this Dev this.
*MainActivity.java
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
private TextView label;
private EditText phoneNum;
private PendingIntent pendingIntent;
private AlarmManager manager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
label=(TextView)findViewById(R.id.entertextlabel);
phoneNum=(EditText)findViewById(R.id.phonenofield);
Intent alarmIntent = new Intent(this, AlarmReceiver.class);
pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, 0);
//pendingIntent = PendingIntent.getActivity(this,1,alarmIntent,0);
}
public void startAlarm(View view) {
manager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
int interval = 10000;
manager.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), interval, pendingIntent);
Toast.makeText(this, "Alarm Set", Toast.LENGTH_SHORT).show();
}
public void cancelAlarm(View view) {
if (manager != null) {
manager.cancel(pendingIntent);
Toast.makeText(this, "Alarm Canceled", Toast.LENGTH_SHORT).show();
}
}
}
*AlarmReceiver.java
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.widget.Toast;
/**

public class AlarmReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent arg1) {
// For our recurring task, we'll just display a message
Toast.makeText(context, "I'm running", Toast.LENGTH_SHORT).show();
Intent in = new Intent(Intent.ACTION_CALL);
in.setData(Uri.parse("tel:[phone]"));
context.startActivity(in);
}
}
I'm getting error "Call requires user permission...."
at
context.startActivity(in);

The issue is resolved.
I used the Flag "FLAG_ACTIVITY_NEW_TASK" with with the intent in AlarmReceiver class.
New code is as follows
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.widget.Toast;
/**
* Created by Saud on 05/11/2015.
*/
public class AlarmReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent arg1) {
// For our recurring task, we'll just display a message
Toast.makeText(context, "I'm running", Toast.LENGTH_SHORT).show();
// Intent in = new Intent(Intent.ACTION_CALL);
//in.setData(Uri.parse("tel:[phone]"));
Intent in = new Intent(Intent.ACTION_CALL);
in.setData(Uri.parse("tel:[phone]"));
in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(in);
}
}
