The most common errors
| Error | Cause | Fix |
|---|---|---|
| "There was a problem parsing the package" | The file did not download completely, or your Android version is too old | Delete the file and download it again; check your Android version |
| "App not installed" | Conflict with an older version of the app | Uninstall the old app first, then install the new one |
| "Install blocked" | Installing from unknown sources is not allowed | Allow it for your browser in Settings |
| Play Protect warning | The app is not from the Play Store | If the file came from the bookmaker's own page, tap "Install anyway" |
| Insufficient storage | The phone is full | Delete unnecessary files or apps |
"There was a problem parsing the package"
This message means Android could not read the file. The most common reasons are an incomplete download, a file that was renamed or opened by another app, or an app built for a newer Android version than yours. To fix it:
- Delete the APK from your Downloads folder.
- Download it again over a stable Wi-Fi connection and wait until the download is 100% complete.
- Open the file from your browser's download list or the Files app, not from a messenger.
- Check your Android version in Settings → About phone. If it is older than the version listed on the bookmaker's download page, use the mobile website instead.
"App not installed"
This usually appears when an older copy of the app is already on the phone and was signed differently, for example a version from another source. Uninstall the existing app first (your account and balance are stored on the bookmaker's server, not on the phone, so nothing is lost), restart the phone and install again. The same error can also be caused by a lack of free space or by a damaged file, so check storage and re-download if needed.
Play Protect warning or "Install blocked"
Google Play Protect warns about apps installed from outside the Play Store, and it may label a betting app as "unknown" or "harmful" simply because it is not in its catalogue. If you downloaded the file from the bookmaker's own page, you can tap "More details" and then "Install anyway". If the warning appears for a file you got from a chat or a third-party website, do not install it. "Install blocked" means your phone does not yet allow installs from the browser you used; see the next section.
Not enough storage
Installing needs free space for both the APK file and the unpacked app, so leave some margin above the file size. Clear the cache of large apps, delete old videos or downloaded files and remove apps you no longer use. On some phones Settings → Storage offers a quick "Free up space" option.
How to allow installs from unknown sources
- Go to Settings → Apps → Special access (or Security).
- Open "Install unknown apps".
- Select the browser you used to download the APK (Chrome, etc.) and turn the permission on.
- Once the app is installed, you can switch the permission off again.
The path differs slightly by Android version and brand:
| Android version | Where to find the setting |
|---|---|
| Android 8 and newer | The permission is given to each app separately: Settings → Apps → Special app access → Install unknown apps → choose your browser or Files app |
| Android 7 and older | One global switch: Settings → Security → Unknown sources |
| Samsung (One UI) | Settings → Apps → three-dot menu → Special access → Install unknown apps |
| Xiaomi, Redmi, POCO | Settings → Privacy protection or Apps → Special permissions → Install unknown apps |
On many recent phones you do not need to look for the setting at all: when you open the APK, Android shows a prompt with a direct "Settings" button.
How to update the app
Apps installed from an APK do not update through Google Play. When a new version is released, the app usually shows an update prompt; otherwise download the latest APK from the bookmaker's own page and install it over the old one. If you get "App not installed" during an update, uninstall the old version and install the new one cleanly.
What about iPhone?
APK files work only on Android. There is no app for iPhone or iPad — nothing to download from the App Store or the website. On an iPhone or iPad, open the bookmaker's website in Safari through our link, register with the code XBUNKER and use the mobile version. Optionally, you can add the mobile site to the home screen (Share → Add to Home Screen) as a shortcut.
Safety rules
- Download the APK only from the bookmaker's own page. "Bonus" or "hack" APKs from Telegram channels are often malware; read more: the truth about Aviator hacks.
- Be careful if an app asks for access to your SMS messages or contacts.
Red flags that an APK is fake:
- The file is sent in a Telegram or WhatsApp chat, or hosted on a file-sharing site.
- Its name promises something extra: "hack", "mod", "VIP", "unlimited bonus" or "predictor".
- The file size is very different from the one stated on the bookmaker's page.
- After installation it asks for accessibility access, device administrator rights or permission to read SMS.
- The login screen looks slightly different or the app asks you to log in again and again.
If you have installed such a file, uninstall it, change your bookmaker and e-mail passwords from a clean device and enable two-factor authentication where available.
