Android集成FAN插屏广告不显示问题及实现方法咨询

Hey there, let's dig into why your Facebook Audience Network (FAN) interstitial ad is showing a blank screen while banners work fine. First off, that SensorManager log you're seeing is almost certainly a red herring—it's a system-level warning that rarely causes ad display failures. The real issue is likely tied to how you're handling the interstitial ad's lifecycle or configuration. Here's how to fix it step by step:

• Double-check you're initializing the FAN SDK early on—call AudienceNetworkAds.initialize(context) in your Application class or the onCreate() method of your main Activity before trying to load any ads.
• Don't mix up placement IDs! Make sure you're using a valid interstitial ad ID from your Facebook Monetization Manager, not a banner ID (it's an easy mistake to make).
• Always load ads asynchronously and use the InterstitialAdListener to track success/failure—this is where you'll get real error details if something goes wrong. Here's a solid implementation snippet:

InterstitialAd interstitialAd = new InterstitialAd(context, "YOUR_VALID_INTERSTITIAL_PLACEMENT_ID");
interstitialAd.setAdListener(new InterstitialAdListener() {
    @Override
    public void onInterstitialDisplayed(Ad ad) {
        // Track when the ad shows up
    }

    @Override
    public void onInterstitialDismissed(Ad ad) {
        // Load a new ad here if you need to show another later
    }

    @Override
    public void onError(Ad ad, AdError adError) {
        // This is critical! Log the full error to figure out what's broken
        Log.e("FAN Interstitial", "Failed: " + adError.getErrorMessage() + " (Code: " + adError.getErrorCode() + ")");
    }

    @Override
    public void onAdLoaded(Ad ad) {
        // Only show the ad if your Activity is still in a valid state
        if (!isFinishing() && !isDestroyed()) {
            interstitialAd.show();
        }
    }

    @Override
    public void onAdClicked(Ad ad) {}

    @Override
    public void onLoggingImpression(Ad ad) {}
});
// Trigger the ad load
interstitialAd.loadAd();

• Interstitial ads need a live, non-destroyed Activity context to display properly. If you're trying to show the ad from a background thread or after your Activity has been paused/destroyed, it'll fail silently (resulting in that blank screen).
• Always add checks like isFinishing() and isDestroyed() before calling show()—like in the code above—to avoid this.
• Don't hold a static reference to the InterstitialAd instance—it can cause memory leaks and context-related issues down the line.

• Ensure your AndroidManifest.xml has the required permissions for FAN to work:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

• Also, verify the FAN activity is declared (it's usually added via manifest merging, but it's worth checking):

<activity
    android:name="com.facebook.ads.AudienceNetworkActivity"
    android:configChanges="keyboardHidden|orientation|screenSize" />

• Use FAN's official test interstitial ad ID to rule out issues with live ad inventory. For Android, the test ID is IMG_16_9_APP_INSTALL#2312433698835503. If test ads show up, the problem is likely with your live placement setup or ad availability.

• While this log isn't causing your ad problem, if you want to clean it up, make sure you're unregistering sensor listeners when your Activity pauses or destroys. For example:

@Override
protected void onPause() {
    super.onPause();
    if (sensorManager != null && sensorListener != null) {
        sensorManager.unregisterListener(sensorListener);
    }
}
