Admob广告在多台安卓设备无法正常显示的原因咨询

Hey there, let's break down why your Banner and Interstitial ads aren't showing up consistently across your Samsung S5, Nexus 5, and Samsung Note 8:

1. Android Version Compatibility #

• Samsung S5 and Nexus 5 max out at Android 6.0 (Marshmallow), while the Note 8 supports up to Android 9 (Pie). Most modern ad SDKs (like Google AdMob) have reduced or dropped support for Android versions below 7.0 (Nougat) in recent updates. If you're using the latest ad SDK version, it might not fully function on these older OS versions.
• Check your build.plugin or related build files for your app's minSdkVersion and the ad SDK version you're implementing. For example, AdMob SDK 22.0.0+ requires minSdkVersion 19 but has limited support for versions below 24.

2. Hardware & Performance Constraints #

• Older devices like the S5 and Nexus 5 have far less processing power and memory compared to the Note 8. Ad loading and rendering can be resource-heavy, and these devices might struggle with the latest ad format optimizations that run smoothly on newer hardware.
• Look for crash logs or ANR (Application Not Responding) reports from these devices when attempting to load ads—this could indicate resource-related bottlenecks causing ad failures.

3. Ad SDK Configuration Checks #

• Double-verify that your Banner and Interstitial ad unit IDs are correctly implemented across all devices. While the Note 8 works, it's worth ruling out any accidental misconfiguration that might only affect older devices.
• Review your build.plugin content for any device-specific filters or configurations that might block ad loading on the S5 and Nexus 5. For example, a setting that restricts ad delivery to devices running newer OS versions.

4. Network & Device-Specific Restrictions #

• Outdated network libraries on older devices might prevent proper connections to ad servers. Also, check if the S5 or Nexus 5 have ad-blocking software (system-level or third-party apps) enabled that's intercepting ad requests.
• Samsung devices sometimes include built-in ad services—ensure the necessary services are enabled on the S5, as the Note 8 likely has these pre-configured out of the box.

Quick Troubleshooting Tip #

Roll back your ad SDK to a version that explicitly supports Android 6.0, and enable verbose logging for your ad SDK (e.g., using AdRequest.Builder().addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build() for AdMob) to get detailed logs about why ads are failing to load.

For a more precise diagnosis, sharing specific code snippets from your build.plugin and ad loading logs from the affected devices would help pinpoint the exact issue.
