Android : Error in Call intent in Android

My MainActvitiy file-

package com.example.call;

import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.view.View.OnClickListener;

public class MainActivity extends ActionBarActivity {
Button b;
EditText e1;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
b=(Button) findViewById(R.id.button1);
e1=(EditText) findViewById(R.id.editText1);

    b.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            String abc=e1.getText().toString();
            Intent i=new Intent(Intent.ACTION_CALL);
            i.setData(Uri.parse("tel:"+abc));
            startActivity(i);

        }
    });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}
}
