How to set your app as default messaging app?

Intent intent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, YOUR_PACKAGE_NAME);

How to check if your app is default messaging app?

@TargetApi(Build.VERSION_CODES.KITKAT)
public static boolean isDefaultSmsApp(Context context) {
    return context.getPackageName().equals(Telephony.Sms.getDefaultSmsPackage(context));
}

From the preference activity add OnPreferenceClickListener and add the following code inside it which first check if it is already a default messaging app, then opens a screen where the user can change it else set the current app as the default messaging app.

 if (isDefaultSmsApp(getActivity())) {
                        startActivityForResult(new Intent(Settings.ACTION_WIRELESS_SETTINGS), 0);
                    } else {
                    final String packageName = getActivity().getPackageName();
                        Intent intent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
                        intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, packageName);
                        startActivityForResult(intent, 0);
                    }
