如何检测AdMob插页广告被Ad-Blocker拦截及获取拦截器包名？

Hey there, I totally get where you're coming from—pouring hours of work into building an Android app only to have ad blockers eat into the revenue that keeps your project going is incredibly frustrating. Let's tackle your questions head-on:

Unfortunately, the short answer is no—there’s no method that can guarantee 100% accuracy with zero false positives. Ad blocker tools are constantly evolving to evade detection, and legitimate scenarios (like poor network connectivity) can mimic ad blocking behavior. That said, there are several approaches that can significantly reduce false positives and help you identify most ad blocking cases:

• Monitor AdMob ad loading status
  Listen to AdMob’s ad load callbacks, specifically onAdFailedToLoad. Pay attention to error codes: if you repeatedly get errors like ERROR_CODE_NETWORK_ERROR when the device has a working internet connection, or ERROR_CODE_INVALID_REQUEST without any changes to your ad setup, it could indicate blocking. Always pair this with a network availability check first to rule out genuine connectivity issues.

• Test reachability of AdMob’s core domains
  AdMob relies on specific domains like googleads.g.doubleclick.net to serve ads. You can implement a lightweight network request (using libraries like OkHttp or the native HttpURLConnection) to check if these domains are reachable. If the request fails but other regular websites load fine, it’s a strong sign of ad blocking. Just avoid overdoing these checks to keep your app’s performance smooth.

• Check for suspicious proxy/VPN configurations
  Many ad blockers route traffic through a proxy to intercept ad requests. You can check the device’s proxy settings using code like:

  String proxyHost = System.getProperty("http.proxyHost");
  int proxyPort = Integer.parseInt(System.getProperty("http.proxyPort", "-1"));
  

  If a proxy is set that the user didn’t explicitly configure, it might be from an ad blocker. But be cautious here—many users use legitimate VPNs for privacy, so combine this with other detection methods.

• Avoid filesystem-based detection (mostly obsolete)
  Some older ad blockers modified the system hosts file, but on Android 10+, apps can’t access this file without root permissions. This method is unreliable now and prone to false positives, so it’s best to skip it.

Yes, but keep in mind this list is constantly changing as new tools launch and existing ones rebrand. Here are some common package names for popular ad blockers:

• com.adguard.android (AdGuard)
• org.adblockplus.android (Adblock Plus)
• com.blokada.android (Blokada)
• com.ghostery.android.ghostery (Ghostery)
• com.adblocker.android.adblock (Adblock Browser)
• net.adblockplus.android (Adblock Plus Browser)
• com.kvantum.android (KVANTUM ad blocker)
• com.webshield.adblocker (WebShield AdBlocker)

A word of warning: detecting solely by package name is risky. Users might have these apps installed but not enabled ad blocking, or some apps are privacy tools that don’t block ads. Always pair package name checks with the ad loading/network reachability tests above to minimize false positives.

Final Tips #

Instead of penalizing users immediately (like locking them out of your app), consider a friendlier approach: show a polite message explaining that ads fund your development work, ask them to disable ad blocking for your app, or offer an affordable ad-free in-app purchase option. This often yields better results than aggressive restrictions.
