What is a secret code?

In Android a secret code is defined by this pattern: *#*#<code>#*#*.
If such a secret code is executed, the system Dialer app will trigger this code: (Source AOSP)

static private boolean handleSecretCode(Context context, String input) {
    int len = input.length();
    if (len > 8 && input.startsWith("*#*#") && input.endsWith("#*#*")) {
        Intent intent = new Intent(TelephonyIntents.SECRET_CODE_ACTION,
                Uri.parse("android_secret_code://" + input.substring(4, len - 4)));
        context.sendBroadcast(intent);
        return true;
    }

    return false;
}

How to execute a secret code?

There are two ways to execute a secret code:

Directly through the dialer application of your Android device.

Simply write the secret code like: *#*#123456789#*#*.

String secretCode = "123456789";
Intent intent = new Intent(Intent.ACTION_DIAL);    
intent.setData(Uri.parse("tel:*#*#" + secretCode + "#*#*"));
startActivity(intent);

String secretCode = "123456789";
String action = "android.provider.Telephony.SECRET_CODE";
Uri uri = Uri.parse("android_secret_code://" + secretCode);
Intent intent = new Intent(action, uri);
sendBroadcast(intent);

How to create your own secret code?

Add these lines in your AndroidManifest.xml
And whenever *#*#123456789#*#* is submitted, your receiver will be notified.

<receiver android:name=".MySecretCodeReceiver">
    <intent-filter>
        <action android:name="android.provider.Telephony.SECRET_CODE" />
        <data android:scheme="android_secret_code" android:host="123456789" />
	</intent-filter>
</receiver>
