Building Your Custom Android APK

This guide will help you create a custom Android APK for 66text. The APK is installed on your Android phone and is responsible for:

Sending SMS messages through your device.
Receiving real-time notifications when new SMS messages need to be sent.

YouTube Tutorial: We also have a full walkthrough on this process. We only send this to confirmed customers. Get in touch.

Tip: Start by setting up Firebase first, then customize and build your app.

Step 1: Configure Firebase

Firebase powers the real-time notifications in 66text. Setting it up first ensures your app can receive SMS tasks later.

Create a Firebase Project

Go to the Firebase Console.
Click Add Project and follow the steps to create a new project.

Add Your Android App to Firebase

In your Firebase project, go to Project Settings → General.
Click Add App and select the Android icon.
Enter your app's package name (this must match what you will use in Step 4).
Complete the setup and download the google-services.json file.
Place the downloaded google-services.json file in your Android project folder at:
```
app/
```

Generate a Service Account JSON

In your Firebase project, go to Project Settings → Service Accounts.
Click Generate New Private Key to download your Service Account JSON file.
From the General tab, copy your Project ID.

Upload to 66text

Log in to your 66text Admin Panel.
Navigate to Settings → SMS → Firebase Settings.
Upload the Service Account JSON file you downloaded.
Enter your Firebase Project ID.
Click Save.

Important: Keep both your Firebase JSON files private and secure.

Step 2: Install Android Studio

Download and install the latest version of Android Studio.

Android Studio is the official tool for building and customizing your 66text Android app.

Step 3: Open the 66text Android Project

Unzip the 66text package you downloaded after purchase.
Inside, locate the file named android.zip.
Extract android.zip to a folder on your computer.
Open Android Studio → Open Project → select the extracted folder.

Step 4: Customize the App Name & Identifiers

To generate a completely unique app, you must customize the following:

App name – what users see on their phone.
Package name – the app's unique technical ID, required by Firebase.
App icon (optional).

Change the App Name

Go to: app/src/main/res/values/strings.xml.
Find the line:
```
<string name="app_name">66text</string>
```

Replace 66text with your desired name:

<string name="app_name">My SMS Gateway</string>

Save the file.

Update the Package Name

The package name uniquely identifies your app on Android and must match the package name you registered in Firebase.

In Android Studio, locate the folder: app/java/com.66text.app.
Right-click → Refactor → Rename → Rename Package.
Enter a unique package name, for example:
```
com.yourcompany.smsapp
```
Open app/build.gradle and update the applicationId to match:
```
applicationId 'com.yourcompany.smsapp'
```
Click Sync Now when prompted.

Tip: Use a reverse domain format like com.mybusiness.mygateway to ensure it's unique.

Customize the App Icon (Optional)

Replace the default icon with your own brand image:

Go to: app/src/main/res/mipmap-*/.
Replace ic_launcher.png files with your icon images.
Or use Android Studio's built-in Image Asset tool.

Step 5: Build the APK

Now that your app is customized, it's time to generate the APK file.

In Android Studio, go to Build → Generate Signed Bundle / APK.
Select APK and click Next.
If you don’t have a keystore yet:
- Click Create New.
- Fill in your keystore details and save the file securely.
Sign the APK using your keystore and click Finish.
The APK will be generated in: app/release/.

Step 6: Upload APK to 66text

After generating your APK, upload it to 66text so it can be installed on your Android device.

Log in to your 66text Admin Panel.
Go to Settings → SMS.
Scroll to the APK upload section.
Upload your newly generated APK and click Save.
Once uploaded, you can download and install it directly on your phone.

Step 7: Install and Test

Install the APK on your Android device.
Open the app and grant all requested permissions (SMS, notifications, etc.).
Send a test SMS from the 66text dashboard to confirm everything works.

Hosting & Domains

These are my recommendations based on past experiences with hosting or domain platforms.

I currently use Hetzner to host all my websites and Namecheap for all my domain names.

VPS Hosting

(Intermediate, Advanced)

For quick & easy VPS server management without complications:

☁️ Cloudways - use affiliated link for $50 credit

If you're comfortable managing your VPS and don't need managed cloud hosting:

🇩🇪 Hetzner - use affiliated link for 20€ credit
🪁 Vultr - use affiliated link for $300 credit

Shared Hosting

(Beginner)

For beginners with limited knowledge, a shared web hosting plan is recommended:

🏷️ Namecheap - recommended for beginners
🌍 Siteground - reliable shared hosting option

Domains

NameCheap for domain registration, they offer good prices and a simple interface without headaches. I've used them since I've started AltumCode.

Frequently asked questions

Any static text from the website can be changed from the Admin Panel -> Languages -> {language name} -> Translate app page.

It is recommended to create a new language instead of editing the original one, so that it won't get overwritten when updating to a new version.

You also have the advanced option to directly edit the app/languages/english#en.php file for the user app side or the app/languages/admin/english#en.php file for the admin panel side.

That is because your current hosting setup does not allow form submissions with all the existing translation fields.

To fix this, you must increase your max_input_vars PHP ini variable to the value you see mentioned in the Admin Panel -> Languages -> {language name} -> Translate app page.

If you do not have the option or do not know how to increase this value, contact your webhost provider.

You can create a new language pack and start translating from the Admin Panel -> Languages -> Create language -> Translate app page.

You also have the advanced option to directly duplicate the app/languages/english#en.php file for the user app side or the app/languages/admin/english#en.php file for the admin panel side following the same naming concept for the file: language_name#language_code.php.

In the vast majority of cases, this is caused by either one of those cases:

Nginx server - You haven't done the Nginx setup properly or at all.

Apache server

You do not have the .htaccess file uploaded.
You do not have proper permissions (CHMOD 644) for the .htaccess file.
Your web host provider does not have mod_rewrite enabled for Apache.
The .htaccess file exists, but the content is not the same as the original file from my product.

If you run a server which supports .htaccess, some servers might not accept the first line of the .htaccess file. Try to delete the first line on the .htaccess file.
If you get this error when submitting a form, this means that your webhost blocked the request. Try to disable mod_security, as it may trigger a false-positive, or contact your webhost provider.

Spam registrations can not ever be fully prevented. No website can do fully get rid of spam. My products offer a lot of spam protection measures, so you would simply have to use them.

Email confirmation - Set from the Admin panel -> Settings -> Users section.
Captcha - Set from the Admin panel -> Settings -> Captcha section.
Country block - Set from the Admin panel -> Settings -> Users section.
Email domain block - Set from the Admin panel -> Settings -> Users section.
Auto delete unconfirmed / old users - Set from the Admin panel -> Settings -> Users section.
Bulk deletion of users - Set from the Admin panel -> Users page. In case you want to delete a lot of users in bulk.
Email shield plugin - Which uses advanced algorithms and multiple blacklists from the web to prevent spam domains sign ups.

Editing the structure & components of the page is done from the themes/altum/views/index/index.php file.

Editing the text is done as mentioned above in the 📝 How can I update text on the website? section.

Editing the images is done directly via the Admin panel -> Settings -> Custom images page.

To disable the original landing page in order to redirect to a custom made landing page, you must go in the Admin panel -> Settings page and find the Custom landing page URL field where you can add your new landing page URL.

You are either not sending the Bearer Authentication header properly, or your web host provider is dropping that header before it reaches my product. In such case, you need to contact your web host provider, or you can personally try a quick fix, which might work for some people: https://stackoverflow.com/questions/26549250/apache-strips-down-authorization-header

This can be done in multiple ways, depending on your actual CSS/SCSS knowledge.

Easiest way: You can edit the theme colors directly Admin panel -> Settings -> Theme page.
You can write your own custom css, that overwrites the already existing rules, and paste that in the Admin panel -> Settings -> Custom CSS field.
You can manually replace the colors via the bootstrap CSS files in the themes/altum/assets/css/ folder.
You can also fully modify the theme, by editing the bootstrap SCSS files in the themes/altum/assets/css/ folder, recompile them back to CSS, and then overwrite the original CSS bootstrap files (advanced).

Keep in mind: Support for any kind of customizations is not included, so this is fully up to you.

You can do this via the Admin panel -> Resources, Pages section.

That is most likely because you've skipped or misconfigured a step when configuring the payment gateway.

In this case, you'd need to access your database manager (such as phpMyAdmin), select the database of the installed product, go to the users table, find your admin account and set the password to $2y$10$uFNO0pQKEHSFcus1zSFlveiPCB3EvG9ZlES7XKgJFTAl5JbRGFCWy which equals to admin as the password. Now you need to find the uploads/cache/ from the product installation files and delete the folder you see inside.
