Broadcast Receiver not correctly grabbing text message contents

Question

I am creating an application that will grab the contents of a text message and display it in a pop up. My Broadcast receiver is not shooting when a text message is received.

Broadcast Receiver class

public class SMSReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();
        Object[] pdus = (Object[]) bundle.get("pdus");
        SmsMessage[] msgs = new SmsMessage[pdus.length];

        /** sms sender phone */
        String smsSender = "";

        /** body of received sms */
        String smsBody = "";

        /** timerstamp */
        long timestamp = 0L;

        for (int i = 0; i < msgs.length; i++) {
            msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
            smsSender += msgs[i].getOriginatingAddress();
            smsBody += msgs[i].getMessageBody().toString();
            timestamp += msgs[i].getTimestampMillis();

        }
        intent.putExtra("sender", smsSender);
        intent.putExtra("body", smsBody);
        intent.putExtra("timestamp", timestamp);
    }

}

Dialog Activity public class PopSMSActivity extends Activity {

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

        showDialog();
    }

    private void showDialog() {
        final String sms_sender = getIntent().getStringExtra("sender");
        final String sms_body = getIntent().getStringExtra("body");
        final long timestamp = getIntent().getLongExtra("timestamp", 0L);
        final String display = sms_sender + "\n" + sms_body + "\n" + timestamp;
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setMessage(display)
                .setCancelable(false)
                .setPositiveButton("Reply",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                // reply by calling SMS program
                                smsReply(sms_sender, sms_body);
                            }
                        })
                .setNegativeButton("Close",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                // go back to the phone home screen
                                goHome();
                            }
                        });
        AlertDialog alert = builder.create();
        alert.show();
    }

    private void smsReply(String sender, String body) {
        Intent sendIntent = new Intent(Intent.ACTION_VIEW);
        sendIntent.putExtra("address", sender);
        sendIntent.putExtra("sms_body", body);
        sendIntent.setType("vnd.android-dir/mms-sms");
        startActivity(sendIntent);
        this.finish(); // close this Activity now
    }

    private void goHome() {
        Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_HOME);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
        this.finish();
    }
}

Manifest

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <receiver android:name="com.example.intereceptsms.SMSReceiver" >
            <intent-filter
                android:exported="true"
                android:priority="999" >
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>

        <activity
            android:name="com.example.intereceptsms.PopSMSActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

    <uses-permission android:name="android.permission.RECEIVE_SMS" />
    <uses-permission android:name="android.permission.READ_SMS" />

</manifest>

I am not pulling up any errors, so there must be something that I am missing, any help will be great. Thank You.

My Broadcast receiver is not shooting when a text message is received

That is because it is not doing anything, other than creating an Intent, which it then ignores. Presumably, your plan is to start PopSMSActivity, in which case you need the startActivity() call.

Also note that, while this is fine for experimentation, users may get very irritated if something takes over the foreground just because a text message arrived.
