Admob广告加载失败求助：ErrorCode:0，新账号无广告显示

Hey there, let's figure out why your ads aren't loading with that ErrorCode: 0 message. Since you just created your AdMob account yesterday, that's the biggest hint here—let's walk through the most likely fixes step by step:

1. Wait for the New Account Cool-down Period #

Google typically takes 24-48 hours to fully activate new AdMob accounts and their associated ad units. During this time, even valid requests might return no ads (ErrorCode: 0) while their systems process and verify your account. This is the most common issue for new users, so give it a day or two and test again first.

2. Use Official Test Ad Unit IDs #

Your current ad unit ID is tied to your new account, which might not be active yet. For testing, replace it with Google's official test IDs to rule out account/unit approval issues:

• For banner ads, use this test ID: ca-app-pub-3940256099942544/6300978111

Update your activity_main.xml like this:

<com.google.android.gms.ads.AdView 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="https://schemas.android.com/tools"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:id="@+id/adView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_alignParentBottom="true"
    ads:adSize="SMART_BANNER"
    android:layout_gravity="bottom"
    ads:adUnitId="ca-app-pub-3940256099942544/6300978111"> <!-- Test ID here -->
</com.google.android.gms.ads.AdView>

If test ads load successfully, that confirms your code is working and the issue is with your account/ad unit activation.

3. Verify Ad Unit Status in AdMob Console #

Log into your AdMob account and check the status of your ad unit:

• If it shows "Pending approval" or "Disabled", that's why ads aren't loading. Wait for approval (usually within 24 hours) or check if you missed any setup steps.
• Ensure your app is correctly linked to your AdMob account (double-check that the app ID in your initialization code matches what's listed in the console).

4. Check Required Permissions #

Make sure your AndroidManifest.xml includes these critical permissions for ad loading:

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

Without these, the SDK can't connect to AdMob servers to fetch ads.

5. Update Google Ads SDK #

Outdated SDK versions can cause compatibility issues. Check your app-level build.gradle and make sure you're using the latest version of the Google Ads SDK:

implementation 'com.google.android.gms:play-services-ads:22.6.0' // Replace with latest available version

You can find the latest version number via Android Studio's dependency update prompts.

6. Dig Deeper in Logcat #

Beyond the ErrorCode:0 message, look for more detailed logs in Logcat. You might see messages like:

• No ad config (indicates no ads are available for your request, often tied to new account status)
• Account not approved (your account is still under review)
  These messages will give you a clearer picture of what's blocking the ads.

Give these steps a try—most likely it's just the account activation waiting period, but testing with the official test IDs will confirm if your code is solid.
