AdMob广告横幅遮挡Android A30导航栏问题求助

Hey there, I totally get how frustrating this sudden UI overlap issue must be—especially since it worked flawlessly just two months ago. Let’s break down some targeted troubleshooting steps and fixes tailored to your UE4 + Android Studio setup:

1. Rule Out SDK or System Updates #

Since the problem popped up recently, it’s likely tied to a change you (or an auto-update) made, or a system update on the A30:

• Roll back your AdMob SDK to the version you were using two months ago and test again. Sometimes newer SDK versions tweak layout logic for system UI elements like navigation bars.
• Check if your A30 received a system OS update in the last two months. If it did, the navigation bar’s height or layout priority might have changed, requiring an adjustment in your app’s UI calculations.

2. Verify UE4’s Android Layout Settings #

UE4 has built-in settings that control how your app interacts with system UI:

• Head to Project Settings > Platforms > Android in your UE4 project. Double-check the Fullscreen Mode and Rendering Resolution options—make sure you aren’t forcing fullscreen mode that overrides the navigation bar’s reserved space.
• If you’re using a custom AndroidManifest.xml, ensure you’ve added the android:fitsSystemWindows="true" attribute to your main activity. This tells the app to automatically adjust its layout to avoid overlapping with system bars.

3. Dynamically Adjust AdMob Banner Position #

Hardcoding banner positions can fail if the device’s navigation bar height varies (e.g., when switching between gesture navigation and virtual buttons):

• Add native Android code to fetch the navigation bar’s actual height, then pass that value to UE4 to adjust the banner’s Y-position above the bar. Here’s a quick code snippet you can use in your Android project:

  Resources resources = getResources();
  int navBarHeightResId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
  int navBarHeight = 0;
  if (navBarHeightResId > 0) {
      navBarHeight = resources.getDimensionPixelSize(navBarHeightResId);
      // Pass navBarHeight to your UE4 game instance here
  }
  

• If you’re using a pre-built AdMob plugin for UE4, check for plugin updates or configuration options that let you set the banner to "avoid system UI" or align to the bottom of the safe area instead of the screen edge.

4. Check App Bundle Packaging Differences #

Compare your current Android Studio build setup to what you used two months ago:

• Did you enable new App Bundle features like Screen Density Splits or Language Splits? Sometimes these splits can cause unexpected resource loading behavior on specific devices like the A30.
• Test building a regular APK instead of an App Bundle to see if the issue persists. If it goes away, the problem is likely tied to App Bundle-specific packaging logic.

5. Test Across Other Devices #

Narrow down if this is an A30-specific issue:

• Test your app on other Android devices with virtual navigation bars. If only the A30 has the overlap, you can add a device-specific check (using the A30’s model ID) to adjust the banner position just for this device.

If the screenshots you mentioned show specific layout hierarchy issues, that could help pinpoint the exact problem—but starting with these steps should give you a solid path to fixing the overlap.
