🚨 Common Problems and Solutions (FAQ)

  • HTML code not working? Double-check that your HTML code is error-free by retesting it with Claude or a similar AI tool. Small syntax mistakes or unsupported elements can cause the app to malfunction, so thorough testing and validation are important before converting your code into an app.

  • App won’t install? Ensure that your device allows installation from unknown sources by enabling this option in your security settings. Without this permission, your device will block the installation of apps that are not downloaded from official app stores. Also, verify that your APK file is not corrupted or incomplete.

  • Can I add more advanced functions to my calculator app? Yes! You can extend your online calculator app with scientific functions like trigonometry, logarithms, or constants like π and e. Using AI code generators, you can request advanced math functions, then integrate and test them carefully. Consider a modular approach so you can update or add new features without breaking existing functionality.
  • What if my app doesn’t pass Google Play Store requirements?
    Google Play Store has policies regarding content, security, and permissions. Ensure your app does not request unnecessary permissions and follows privacy rules. Also, prepare proper app descriptions, screenshots, and use a unique package name. Testing your app on Google’s pre-launch report can help identify compliance issues before publishing.

  • How do I update my app after publishing?
    After initial publication, you can create a new version of your APK with bug fixes or new features and upload it to your developer console. AppsGeyser allows easy rebuilding and updating of your APK. Keep your users informed about updates through release notes or push notifications if supported.

  • What if I want to customize the app design?
    AppsGeyser provides options to customize icons, splash screens, and colors. For more advanced design changes, you might edit the HTML and CSS directly before converting to an app. Using AI tools, you can generate design suggestions or code snippets to enhance your UI. Remember to maintain usability and accessibility in your design choices.
